Carbon fiber composite materials have been widely used in the field of medical devices. This is mainly because of the continuous development of the medical industry. The choice of medical equipment and devices is more inclined to high-performance and high-precision materials. As a high-performance material widely used in recent years, carbon fiber composite materials have also been used for research and testing. It is found that the performance advantages of carbon fiber medical devices are better, This is the important reason why carbon fiber is used in medical devices. Carbon fiber stretcher Stretcher is a medical instrument often used in hospitals. The important function of stretcher is to fold and carry easily. The weight of carbon fiber composite material is only one quarter of that of steel, but the mass is three times of the rigidity. That can greatly reduce the convenience of our medical staff in the use of stretcher. The bearing capacity is also better. The other is that the wear resistance of carbon fiber composites is also very good. The service life of carbon fiber stretchers using carbon fiber composites is also longer. Carbon fiber medical board The medical board is mainly used for CT photography and the bed board of medical devices. The important reason why this medical device uses carbon fiber composite material is that, in addition to its light weight, high strength and better mobility, the carbon fiber composite material has a relatively high rate of radiation transmission, which can help us to obtain better images during the examination process and facilitate targeted treatment. Carbon fiber prosthesis Carbon fiber prostheses are those that need to be used by patients. Because carbon fiber has different properties because of different resins, the carbon fiber prostheses made of PEEK food-grade carbon fiber composites can better achieve skin-friendly effects without rejection. According to the above contents, there are many reasons for using carbon fiber composites in medical devices. The important reason is that the medical devices produced by carbon fiber composites can better meet the market needs and improve the performance of medical devices. Medical devices also need more technical support.

1. High strength This is an important advantage that we must say when we talk about carbon fiber. The carbon fiber UAV parts with very high strength can well meet the strength requirements of UAVs in some special environments, such as poor operation, drop, collision, etc. Because of their high strength, they can well guarantee the damage of UAVs. 2. Strong corrosion resistance Carbon fiber products have very good corrosion resistance because of the resin material in their prepreg. The carbon fiber composite has stable chemical structure, is resistant to acid, alkali, salt spray and other complex environments, and can be used for a long time without fear of rust corrosion. It has low thermal expansion coefficient, good material stability, relatively low maintenance cost, convenient storage and transportation, and long service life. 3. High impact resistance The UAV made of carbon fiber composites has good safety, impact resistance and high designability in terms of overall performance. The high strength of carbon fiber can resist the strong resistance when flying, and it is not necessary to worry about damage when hitting other objects due to careless operation mistakes.

How much does it cost to install the carbon fiber tail? The current market price of real carbon fiber tail is about 500-2000 yuan, and the price of customized carbon fiber tail of some luxury cars may be tens of thousands. Due to the strong customization of carbon fiber parts, the manufacturing process can refer to how the carbon fiber products for automobiles are produced as we introduced earlier. Basically, each type of tail needs to be made by hand. Therefore, genuine carbon fiber tail, especially the tail with good process quality, is more expensive. At the same time, for the customized tail fins of some luxury cars, due to the high price of mold opening components (such as the original tail fins or the original factory modified tail fins ordering mold opening), there are few orders after mold opening, which also causes the market price of these personalized carbon fiber tail fins to remain high. We often see carbon fiber tail fins with complex and beautiful structures installed on sports cars. In daily life, we can also see that some modified cars are equipped with automobile tail fins. The price for installing carbon fiber tail fins is about how much. How to choose carbon fiber tail? Today we will take you to know whether the carbon tail you hope to install will really play its role as you expect? The tail wing, diffuser, turbocharger and carbon fiber body are known as the four piece kit of the automobile industry! If you can figure out some high case terms such as pneumatic modeling, downforce, aerodynamics, etc., it will take you a minute to deal with girls. But as the title says, "The tail is not installed if you want to.".

It is the first time to see a modified carbon fiber, which is like a woven bag. Like LV woven bag, even if the LV brand is hung, it still looks very bad, but little brother A Chang, the modification technician of Balance, praises it endlessly. The little mosquito wondered, is it really so good? I learned that I was really misled by his unattractive appearance. So people, the more ignorant they are, the easier it is to make subjective judgments. Carbon fiber has many excellent properties, such as low density, high strength, good over temperature resistance, fatigue resistance, small thermal expansion coefficient, anisotropy, good corrosion resistance, and good X-ray transmission. Materials with these characteristics are used on vehicles. In the sporty direction, lighter weight can perform better when the vehicle is accelerating, braking or cornering. It has high strength and can achieve better transmission efficiency when applied to the half shaft and transmission shaft. Giulia and Stelvio of Alfa Romeo also have applications. The proportion of Giulia and Stelvio carbon fibers of Alfa Romeo is less than 1/4 of that of steel. The tensile strength of carbon fiber resin composites is more than 3500 MPa, and the tensile elastic modulus is 23000 ~ 43000 MPa, which is also higher than that of steel. These characteristics make carbon fiber the most lightweight body modification. But carbon fiber is also fiber, why is it so expensive? It is expensive mainly for four reasons. 1,?? For raw materials, only 1 ton of carbon fiber can be burned from 2 tons to 2.2 tons of raw silk, with a cost of about 40000 to 60000/ton. 2,?? For equipment cost, the import of a thousand ton line for a complete set of equipment will be more than 200 million, and if some of the equipment is made in China, it will also be 150 million, with an annual production capacity of about 1500 tons. 3,?? The processing technology of carbon fiber is heat treatment, which requires a large amount of electricity, accounting for 25% - 30% of the production cost of carbon fiber. (This electricity bill is really expensive.) 4,?? The R&D cost is high because carbon fiber is a multidisciplinary product with about 3000 control points in the whole process. BMW Carbon Fiber Bicycle 2000 US $Yema Carbon Fiber Bumper 800 US $Carbon Fiber also has two points to pay attention to: 1. When purchasing carbon fiber modified parts, pay attention to the resin types in carbon fiber products, including cyanate ester resin, epoxy resin and ester resin. The three grades are decreasing. Cyanate ester resin is mainly used in aerospace and military industries. 2. Poor plasticity. At present, many of our car bodies can be repaired after collision, because steel and other metal materials have ductility. The carbon fiber material only shows high strength along the fiber axis, but its impact resistance is poor, and it is easy to be damaged. After collision, it cannot be repaired, so it can only be replaced as a whole. Ferrari? Therefore, the price of carbon fiber is high due to its characteristics, cost and irreparability. The all carbon fiber body Koenigsegg Knox has released a report. In the "Road Map for Expanding the Application of Carbon Fiber in Automobile", it is said that by 2025, the application of carbon fiber in automobile will become mainstream. The progress of carbon fiber processing technology, the increase of patent number and the control of production cost will slow down the price of carbon fiber automotive supplies. This article comes from the author of the car home number, which does not represent the standpoint of the car home.

When the new generation 911 GT2 RS is about to be launched, Manhart has brought a retrofit kit for the 991.2 generation GT2 RS, which has further improved its power and visual effect. Manhart TR900 is based on the highest 911 GT2 RS with Weissach and Clubsport. In terms of appearance, this track monster has been replaced with carbon fiber accessories including front splitter, air inlet, side skirt and diffuser developed by DB Carbon. Fortunately, the refitter did not replace the Y-spoke central locking magnesium alloy wheel in Weissach kit. The gold color of the wheel hub echoes with the new sticker, which reflects the deep midnight green paint of the car body. In terms of power, the original factory output of the 3.8T twin turbocharged horizontally opposed six cylinder engine is 690 horsepower and 750 Nm. After installing the ECU rewriter of Mapswitch, TTH 1000 turbocharger, CSF intercooler, Manhart IPD aluminum alloy manifold and the tail section of Kline Innovation, the comprehensive output is increased to 945 horsepower and 1050 N · m, and the 7-speed PDK dual clutch transmission has also been upgraded. The only thing that remains unchanged is the original Porsche carbon fiber ceramic brake disc. After all, the performance is really outstanding. At present, the price of the retrofit kit Manhart has not been announced. As a reference, a 2018 911 GT2 RS Weissach was sold for 443000 dollars a few months ago. It seems that refitted cars with more than 900 horsepower are really commonplace. Which do you prefer, the original or the Manhart TR900?

Whether you support EV sports, which has almost occupied the automotive news field in recent years, or not, things are changing rapidly.

According to this model of BMW, the concise version, classic version and retro version at the beginning of Z are presented respectively. The three versions can be switched freely according to your favorite and desired feeling. Literally, it means the simple style when R18 was first released, the classic style modified according to the body, and the vintage blood style to show these versions. There are 15 kinds of optional refitting parts specially designed for R18, which can be used to create three types of cars that meet the public's aesthetic preferences. Let's have a look. 1. Cruise style windshield The original R18 was designed for riding. It is divided into transparent color and smoke gray. The function of windshield is self-evident. It uses PMMA plastic. This PMMA: polymethyl methacrylate is the chemical name of polymethyl methacrylate, which is a polymer compound polymerized from methacrylate. It has smooth surface, bright color, small proportion, high strength, corrosion resistance, moisture resistance, sun resistance, good insulation, sound insulation and other properties. The windshield is 460mm wide, 405mm high and 5mm thick. 2. Sports windscreen PMMA plastic materials are still used, including black, transparent and black gray, with width of 325 mm, height of 320 mm, depth of 80 mm and thickness of 5 mm. It has a fashionable feeling of rock music when combined with the lampshade. 3. Rock music lampshade A specially designed handlebar cover combines noble appearance with sportiness in a balanced way. The perfect match with the windshield is also available in black, smoke gray and transparent colors. The lampshade is exquisite, which truly encloses the headlights. It has a unique design and obvious high recognition. It is made of high-quality ABS plastic. Width: 340mm, height: 430mm, depth: 340mm, thickness: 5mm. 4. Handlebar heightening Raise the handlebar base by about 25 mm. The tilt of the handlebar and the seat position can adapt to personal needs and improve significantly, greatly improving the riding suitability and comfort. There are two kinds of black and silver, which are made of high-strength aluminum precisely processed in the machine shop. 5. Handlebar end mirror This is a customized model. The mirror is very clear and thin, and can be installed at the end of the handlebar, without disturbing the lines of the motorcycle. The mirror surface has a diameter of 100 mm, and the mirror arm length is 120 mm, which is suitable for handlebars with a diameter of 22 mm. This kind of demand is not very clear, but thousands of people have their own preferences. 6. Wunderlich swing saddle "RockBob" The unique swing saddle is made of "RockBob" style leather. It adopts diamond texture structure. The gradual two-layer structure of the seat core has a soft top layer and a tight core, which can ensure comfort and reduce the specific pressure load on the hips. It is specially tailored for the seat geometry of BMW R 18. The 3D contour has a forced hollow groove for reducing the tailbone, which realizes excellent ergonomic seat comfort and allows riders to use it to increase riding comfort. It is divided into R18 classic version and 2020 version, with black and brown colors available. The seat height is 735 mm, about 45 mm higher than the R 18 standard seat height, and about 25 mm higher than the R 18 Classic standard seat height. 7. Spring for swing saddle "RockBob" group The swing saddle at the rear of the "RockBob" is equipped with black saddle springs with soldering color and powder coating, which are made of spring steel. The convex winding structure is used. If you don't like the original soldering color, you can have more choices. The black color also highlights the atmosphere, which is also very consistent with the color matching of the original car. Similarly, there are two different versions of R18 classic and 2020.

Types of carbon fiber modification 1: Graphic sticker. Many people just like the pattern of carbon fiber and want to spend a small price to modify the carbon fiber, so this carbon fiber decal is very suitable, because it costs only a few yuan and dozens of yuan for a bundle, so they can paste the whole vehicle. But this kind of carbon fiber decal has only lines, not the true three-dimensional sense of carbon fiber. It is called false carbon fiber. 2: Water transfer carbon fiber Water transfer printing of carbon fiber will slightly raise the level of carbon fiber decals. Its carbon fiber pattern is a water transfer process, covering the upper layer of the piece with carbon fiber patterns. Its price is actually the price of plastic pieces. Therefore, it does not have the three-dimensional sense of real carbon fiber, but also belongs to false carbon fiber. 3: Carbon fiber cladding Carbon fiber cladding, the so-called carbon coating. It is a real carbon fiber, but it is wrapped with a layer of carbon fiber cloth on the surface. The low parts are still of the quality of plastic or metal and other original parts. The coating of carbon fiber will lead to orange peel, blistering and other phenomena after a long time, so its quality is not as good as that of full carbon, and the price will be very attractive. 4: Wet carbon fiber This is a real carbon fiber, which is a grade higher than the previous ones. However, wet carbon fiber production is a common cost-effective production process, with resin plus glass fiber on the back and carbon fiber on the surface. With this production process, more people who like carbon fiber will not stop because of the price. It has the same quality and texture as pure carbon. It's just that the weight is not as light as pure dry carbon. If it's not racing track and pursuit of light weight, then I highly recommend using wet carbon fiber. 5: Dry carbon fiber patch Pure carbon fiber production process, but this is a patch, which is installed with adhesive, and pasted to the original car parts to make a decoration. 6: Dry carbon fiber replacement - Z top carbon fiber Here, the top carbon fiber is the replacement of dry carbon fiber. It is made of pure carbon fiber, lightweight, and hard to harden. Its price is also the highest.

It is easy to tell how many pistons a caliper is. The round mouths on both sides of the caliper are the pistons. Count them, and there are several pistons that are several pistons. This can be known at a glance, just give Xiaobai some popular science. Generally speaking, we modify the brakes to change the calipers of the opposite piston type. The calipers are: four-piston, six-piston, eight-piston. 1. First of all, to correct a wrong statement, it is not that the more pistons the caliper, the stronger the brake. Whether the braking effect of a car is good or not depends on too many things, such as oil circuit design, brake master cylinder, pedal design, brake oil selection, brake disc, brake pad and so on. For example, some American big bikes have single-piston floating calipers, but the pressure of the calipers can crack the discs of ordinary family cars. So the question is, what is the difference between multi-piston calipers and single-piston calipers? The answer is that the multi-piston caliper has more friction area, the caliper is smaller, and the brake feedback is more delicate. 2. Of course, some car owners will ask, after changing the multi-piston caliper, will the master cylinder of the original car not be able to carry it? This question depends on the fuel supply data of your car's master cylinder. Generally, the car on the market, such as the master cylinder of the BMW F3/8x code, can be driven completely. (It is a few models that cannot be driven. When you change the brakes, the technician will tell you) 3. Also, some car owners bought a complete set of imported original car brake calipers, thinking that there will be no jitter problem after they are installed on the car. To explain here, it does not mean that the full set of imported brake calipers will not shake. Because every car is made of tolerances, and over time, the car itself will wear out. These small errors will affect the performance of the caliper. This problem is written in the manual of the brake caliper kit. Common old brake brands are: Brembo, AP, alcon, endless. These are the four kings of brake brands. These four brands are also regulars in DTM, Le Mans and other events. As for the new generation of brake brands, there are also many, but the quality still has to pass the test of time, so I will not recommend it here. As for the question of how many piston calipers should be selected, I can only give a rough reference here. After all, the problem of this relationship is a bit complicated, and you can consult if you need it.

The steering wheel modification should be a question that many car owners have considered. So whether the steering wheel modification is illegal or not will affect the annual review? The answer is that the steering wheel modification is not illegal. As long as it does not affect normal driving, car owners can change the steering wheel to the way they like according to their own preferences. It should be noted that the steering wheel can only be modified from the outside of the steering wheel. For example, it is OK to replace the steering wheel with a carbon fiber steering wheel or upgrade the T-Carbon carbon fiber steering wheel patch. However, the internal structure of the steering wheel is not allowed to be changed at will, because there are many very important parts involved in the steering wheel, such as the airbag structure and the steering system are also controlled and applied through the steering wheel, These are related to whether the vehicle can be used normally. In addition, some car owners will ask whether the steering wheel modification needs to go through the filing formalities? The answer is still no. It is particularly important to remind all car owners that they must go to a regular 4S shop or a professional refitting shop to refit the steering wheel. The steering wheel is related to vehicle safety, so they must be careful. If only the system is refitted to improve the vision of the steering wheel, then there is no need to refit the steering wheel, just replace the T-Carbon Net carbon fiber steering wheel patch is enough. Compared with upgrading to carbon fiber steering wheel, the carbon fiber steering wheel patch can also achieve a cool effect, and has higher cost performance.

Just bought a new car and started to go on the road, the most likely problem is the car paint. The paint surface is scratched, and the scar should be light white. In that case, it is fine. It only needs to be polished with coarse wax for a few times, and there is no need to do too much treatment. Dongguan Ludi Automobile Technology Co., Ltd. - BMW modification, Mercedes-Benz modification, Audi car modification parts production company, let's briefly talk about it: 1. Color of refinish paint The color of the refinish paint is generally prepared by the repair personnel on the spot. Because the length of the car's use time and the frequency of use are different, the paint of the car will fade to varying degrees. The color difference affects the appearance. In addition, in order to reduce the chromatic aberration, the repair personnel will generally re-spray all the associated car bodies to reduce the degree of chromatic aberration. A small touch-up paint has a lot of knowledge in it. In fact, the original paint is better, because the process of the original paint is very high-end, and the paint that is repaired in the later stage cannot be compared with the original paint environment alone. Compare. The editor suggests that if it is only a small scratch and the metal surface is not exposed, do not touch up the paint. If the metal surface has been exposed, there is no way to do it, and only the paint surface can be repaired later. Second, paint attention points If the car paint is only scratched on the surface, it does not matter if it is not treated. If the scratches are serious, the primer can be seen, and the scratched parts are parts made of engineering plastics such as bumpers, rear-view mirrors, etc. It doesn't matter if these parts are scratched or repaired, it depends on the owner. Willing. If the heavily scratched part is on other parts of the body, it must be repainted. If it is not repainted, the steel plate will begin to rust. Once it has rusted, it will be useless to touch up the paint. When refinishing paint, you should go to a professional paint spraying factory. If you want to get a good spray painting effect, you must need a dust-free high-temperature paint baking workshop and a highly skilled paint sprayer, so you must find a professional paint sprayer. factory. Here, what the editor wants to say is that some maintenance companies say that they use the original paint for repairs, which is simply impossible, because the original paint needs to be baked at a high temperature of 200 ° C. If it is If you use the original paint to repair, the other parts on the car may not be able to withstand the high temperature of 200 ° C. In fact, the paint used for the repair is specially designed for low-temperature baking.

What should I pay attention to when cleaning the air suspension of the car? Dongguan Ludi Automotive Technology Co., Ltd. - BMW modification, car modification, BMW modification company and tell you: This link should not be underestimated. For some riders, the shock absorber airbag leaks and a small hole appears, which makes it impossible to use it normally! This situation is rare, mostly for the rear shock absorber airbag, there are two main reasons 1. Hard objects (such as small and hard sand and stones) enter the tray carrying the airbag. While the airbag springs bear the weight of the vehicle for a long time, they are worn by the hard objects and cause air leakage! ! 2. After the installation is completed, the construction party does not check whether there is friction with the metal around the airbag spring, which causes the airbag spring to rub against it for a long time, wear out and leak! ! So when you wash your car, or when you are about to repair and maintain it, pay attention to the gaps around the airbag, whether there are hard objects or friction points! ! Dongguan Ludi Automobile Technology Co., Ltd. is a professional research and development, production and sales of automotive carbon fiber exterior modification parts, mainly including car hood, large surround, front lip, rear lip, side skirt, rear wing and various carbon fiber products; the company upholds integrity , innovative, professional and efficient service tenet, people-oriented, service-oriented, win-win cooperation, pursuit of excellence business philosophy, dedicated to creating a professional car carbon fiber exterior modification parts sales service organization.

Is there any way to modify the exhaust without affecting the low torque? Dongguan Ludi Automobile Technology Co., Ltd. - Audi modification parts production, Audi modification parts, Audi modification parts manufacturer and share with you: I believe everyone wants to say whether there is such a thing that can take into account the high back pressure at low speed and low back pressure at high speed? And this is the more popular valve exhaust at present. Simply put, it is installed on the exhaust pipeline. An adjustable valve that controls exhaust back pressure based on valve opening and closing. This has to mention passive valves and active valves. Passive valves do not require additional power to be driven, and are generally installed inside the muffler or on the connecting pipe at the mid-end. It is mainly composed of a spring and a baffle. When the engine speed is low, the exhaust airflow is small, which is not enough to overcome the tension of the spring to blow the baffle up, and the exhaust pipe is blocked by the baffle, so the back pressure becomes larger. When the engine speed is high, the exhaust airflow is large enough to blow the baffle up, and the exhaust pipe is fully opened at this time, and the back pressure is low, thus ensuring the power output of the engine. Active valves require additional power to drive, generally installed on the tail pipe, and are divided into electric valves and pneumatic valves according to different driving methods. The electric valve is driven by a motor, and the pneumatic valve is driven by a vacuum pump. Similar to passive valves, when the engine speed is low, the valve is closed to increase the back pressure, and when the engine speed is high, the valve is opened to reduce the back pressure. Compared with the passive valve, the active valve has lower back pressure at high speed, because the opening energy of the valve is provided by the battery, which will not cause the power loss of the engine, and the passive valve requires a part of the energy from the engine to overcome the tension of the spring, but this part of the energy is very small and can be ignored. Therefore, modification is not a simple matter. Any modification requires an understanding of the influencing factors and principles behind it.

How to choose the right brake caliper when modifying the brakes of your car? Ludi Auto Technology - BMW modification, Mercedes-Benz modification, Audi modification parts manufacturer and share with you: Generally speaking, we modify the brakes to change the calipers of the opposite piston type. The calipers are: four-piston, six-piston, eight-piston. It is easy to tell how many pistons a caliper is. The round mouths on both sides of the caliper are the pistons.

When you are refitting Benz, don't step on the thunder to report the misunderstanding. I will tell you about this in detail in the following. In addition, no modification is 100% safe, which is also the reason why many people want to modify but dare not find it. It depends on their choice. If you particularly want to transform yourself, you should also carefully consider it. I. modification Report some car owners like to take precautions in advance or complete some tasks in advance, for example, they plan to refit Mercedes Benz. When there is no modification, it is meaningless to go to the relevant institutional departments to report the modification content. Because the change can't catch up with the plan, you said that it might not be necessary to refit after it was refitted to Z, but after it was reported, it was after the refitting. This will have a certain impact. It must be reported after the modification is successful. This is really effective. II. Modification accident if you pay more attention to the information about Mercedes Benz modification, you will find that there are some modification accidents. The reason why these accidents occur is that the modification is not in place. It may be the problem of the replaced equipment, or it may be the problem of the installation during the installation, so the consequences are very serious. If only property is lost, it is only financial loss, and there is no danger in terms of personal safety. However, some car owners have caused some traffic accidents because of the high risk of transformation, which has caused great harm to themselves. Some of them are even irreparable, like this, which is really not advocated. Therefore, when refitting, it is also necessary to select a reliable platform or reliable personnel with certain transformation ability.

1. Selection of car audio wiring (1) The smaller the resistance of the car audio wire, the less power is consumed on the wire, and the higher the system efficiency. Even if the wire is thick, the efficiency of the whole system cannot be achieved because the speaker itself will lose a certain amount of power. (2) The smaller the wire resistance, the greater the damping coefficient; the greater the damping coefficient, the greater the redundant vibration of the speaker. (3) The larger the cross-sectional area of the wire (the thicker), the smaller the resistance, the greater the allowable current value of the wire, and the greater the allowable output power. (4) The choice of power insurance. The fuse box for the mains cable should be as close as possible to the car battery. The insured value can be determined according to the following formula: Insurance value = (sum of total rated power of all power amplifiers in the system 2)/average value of vehicle power supply voltage 2. Wiring of the power cord (1) The current capacity value of the selected power cord should be equal to or greater than the value of the fuse connected to the power amplifier. If you use a sub-standard wire as the power cord, it will generate humming noise and the sound quality will be severely compromised. (2) When the power line is used to supply power to multiple power amplifiers separately, the wiring length and structure from the split point to each power amplifier should be the same. When the power lines are bridged, a potential difference is created between the power amplifiers, resulting in AC noise, which can seriously damage the sound quality. When the host is powered directly from the mains, it reduces noise and improves sound quality. (3) Thoroughly remove the dust on the power (battery) connector and tighten the connector. If the power connector is dirty or not tightened, there will be contact resistance at the connector. The presence of contact resistance can cause humming noise, which can seriously impair sound quality. Use sandpaper and a fine knife to remove any dirt from the seams. (4) When wiring is used for the vehicle power system, avoid wiring near the generator and ignition device. Generator noise and ignition noise can radiate into the power lines. When the factory-installed spark plugs and spark plug cables are replaced with high-performance ones, the ignition spark is stronger, which in turn is more prone to ignition noise. (5) The principle to follow is the same for the inner power cable and the audio cable. 3. Wiring of audio signal lines (1) Wrap the connector of the audio signal cable tightly with insulating tape to ensure insulation. When the joint comes into contact with the body, noise may be generated. (2) The audio signal line is as short as possible. The longer the audio signal line, the more susceptible it is to interference from noise signals. Note: If the length of the audio signal cable cannot be shortened, the extra long section should be folded instead of rolled. (3) The wiring of the audio signal line is at least 20 cm away from the power line that drives the computer unit and the power amplifier. If the wiring is too close, the audio signals that the wires can pick up can create induced noise. Separate audio signal and power cables on both sides of the driver's and passenger's seats. Note that when approaching the wiring of the power cord and the microcomputer unit, the audio signal lines must be more than 20 cm away from them. If the audio signal line and the power line need to cross, we recommend 90 cross.

Dongguan Ludi Automobile Technology Co., Ltd. - BMW modification, Mercedes-Benz modification, Audi modification parts manufacturer has sorted out several fuel-saving operations for automatic transmission models for riders: 1. Smooth driving Do not deliberately stress the speed of acceleration for an automatic transmission car, because the automatic transmission is designed for comfort. When driving normally, you only need to step on the accelerator pedal for about 1/3, and the transmission computer will control the transmission according to the vehicle speed and engine load signal. Upshift. If you need to overtake, quickly depress the accelerator to the bottom, and the gearbox will forcibly lower 1-2 gears to increase the torque. After overtaking, release the accelerator quickly and return to normal driving. The forced downshift should not exceed 5 seconds, and the forced downshift will Serious impact on the automatic transmission should be avoided if there is no special need. 2. Correct operation When starting, step on the brakes, put the gear lever into the driving gear, wait for 0.5 seconds, and feel a slight vibration of the body before starting; if you don't wait for 0.5 seconds or feel no vibration, release the brake and step on the accelerator, which will cause the automatic transmission. Internal shock, resulting in rapid wear. If the ground is flat, the brakes are released, and the vehicle does not crawl, there is a problem with the transmission or braking system. When the car is not stopped, do not engage the opposite gear and P gear, which will cause serious damage to the automatic transmission. 3. Upshift in advance If you drive an automatic transmission car late, do not step on the accelerator very much, this will only have the opposite effect. Because the automatic transmission skip time is judged by the computer according to the vehicle speed signal and the engine load signal, the engine load signal depends on the size of the accelerator; under normal circumstances, the larger the accelerator at the same speed, the later the skip, and the smaller the accelerator, the skip. The sooner, so when the speed of the car is about to reach the upshift point, you can release the accelerator, and the transmission will upshift in advance, which can achieve the effect of saving fuel. Fourth, pay attention to maintenance Regularly clean the radiator of the engine radiator, maintain a normal water temperature, and clean the engine throttle valve and injector regularly, so as to save fuel and obtain a good shifting feeling. The transmission oil does not need to be changed frequently, and the oil change interval is generally 4- 60,000 kilometers, you must use the oil of the level specified by the manufacturer when replacing it. You can't add less or more. Never use inferior automatic transmission oil. The inferior oil has poor anti-oxidation and lubricating ability, and the gearbox is used for a short time. It will be seriously worn and glued, the light is overhauled, and the gearbox is scrapped.

Regarding the composition and function of each part of the automobile transmission system, the Dongguan Ludi Auto Technology carbon fiber Audi modified parts manufacturer is introduced as follows: An overview of the transmission system It is introduced that the basic function of the drive train is to transmit the power released by the engine to the driving wheels of the car to generate driving force, so that the car can travel at a certain speed. For a car with front and rear drive, the torque released by the engine is sequentially transmitted to the rear wheels through the clutch, gearbox, universal joint, drive shaft, final reducer, differential, and half shaft, so the rear wheel is also called the rear wheel. for the drive wheel. When the driving wheel gets the torque, it will give a backward force to the ground, and thus cause the ground to generate a forward reaction force against the driving wheel, and this reaction force is the driving force of the car. The front wheel of a car generally has no direct power connection with the drive train, so it is called a driven wheel. The composition and placement of the drive train varies with the type of engine, the orientation of the equipment, and the purpose of the car. For example, off-road vehicles mostly use four-wheel drive, and then an assembly such as a transfer case is added to its drive train. 2. The placement type of the drive train Tell everyone that the common installation type of mechanical drive train is mainly related to the position of the engine and the drive type of the car. It can be divided into: 1. Front Front Drive-FR: Front-engine, rear-wheel drive This is a traditional placement type. Most of the trucks, some cars and some passenger cars at home and abroad use this type. 2. Rear rear drive - RR: that is, rear engine, rear wheel drive This type of placement is mostly used on large passenger cars, and a few miniature and light cars also use this type. The rear-mounted engine makes the front axle less likely to be overloaded, and can make more full use of the trunk area. It can also effectively reduce the height of the body floor or make full use of the space under the floor in the middle of the car to place luggage, which is also conducive to reducing the high temperature and noise of the engine. Impact of the driver. The disadvantage is that the engine has poor heat dissipation conditions, and some faults in travel are not easily detected by the driver. Remote control also complicates the control mechanism and makes it inconvenient to repair and adjust. However, because of its outstanding advantages, it is used more and more in large passenger cars. 3. Front Front Drive-FF: Front-engine, front-wheel drive This type of control mechanism is simple and the engine heat dissipation condition is good. However, when the car mass moves backward when going uphill, the adhesion mass of the front driving wheel is reduced, and the driving wheel is easy to slip; when braking downhill, because the mass of the car moves forward, the front wheel is overloaded, and it is prone to rollover at high speed. Most cars now take this type of placement. 4. The drive train of an off-road sedan Off-road cars are generally all-wheel drive, the engine is in front, and a transfer case is installed behind the gearbox to transmit power to all wheels. At present, light off-road sedans generally use 4×4 drive type, medium-sized off-road sedans use 4×4 or 6×6 drive type; heavy off-road sedans generally use 6×6 or 8×8 drive type.

What is the function of installing car springs? Dongguan Ludi Auto Technology - carbon fiber BMW modification, Mercedes-Benz modification parts, Audi modification parts manufacturer to share with you the introduction of BMW modification shop as follows: First, the meaning of spring modification: The BMW refit shop introduced that the spring mainly plays a role in linking the handling. The essence of modifying the car spring is to improve the handling. Generally, the springs that are harder or shorter are replaced. The springs control many factors related to control. The change of the spring It will cause a very complex change in handling characteristics. In terms of stiffness, the rolling resistance of the suspension can be improved and the rolling of the body during cornering can be reduced. The lowering of the car height can simultaneously lower the center of gravity of the body, reduce the transfer of body weight when cornering, and improve stability. And the reduction of the car height can also take into account the aesthetic effect. Second, the basic functions of the spring: The BMW tuning shop introduced that one is to serve as a buffer between the suspension system or the chassis and the ground, that is, to maintain comfort, and the other is to keep the tires on the ground when the car is running on uneven roads. 3. Explanation of mainstream springs - progressive springs: The BMW tuning shop tells everyone that in order to better realize the basic function of the spring, a nonlinear spring with a compound elastic coefficient, also known as a progressive spring, will be used. Progressive springs can increase the spring rate as the spring compresses, and require a high degree of skill in design and manufacture. When traveling on bumpy roads, the spring rate will increase to maintain the stability of the body. The current progressive springs are mostly unequal-pitch springs or springs with variable coil diameters. When the unequal-pitch springs are compressed, local line-to-line contact will occur, so that the effective number of turns will change, resulting in changes in the elastic coefficient K. The change of the upper and lower ring diameters is the Z direct method of changing the elastic coefficient.

Brabus, the world-famous tuning brand for tuning Mercedes-Benz cars, recently released their aerodynamic kits and interior trim parts specially designed for the electric car EQS. Officials claim that taking the EQS 450+ model as an example, the wind resistance coefficient is lower after installation, and the battery life can be increased by 7% when driving at a speed of 100 to 140 kilometers per hour. The modification of electric vehicles is quite special. In order not to destroy the original warranty regulations, only the interior and exterior are upgraded, and these kits are common to all EQS vehicles. In addition to watching the excitement, prospective car owners can also pay special attention. It is not the first time for Brabus to modify an electric car. Not long ago, it launched an exclusive appearance kit for the Porsche Taycan. However, considering the original factory warranty plan, it is only limited to the kit, and does not involve the body structure and power programming. Based on the above reasons, the modification kits specially launched for Mercedes-Benz EQS (parameters | inquiry | pictures) this time also only have interior appearance kits, emphasizing not on performance, but on improving battery life. Officially, the EQS 450+ is used as a modification example. After replacing the appearance kit specially designed by Brabus for EQS, in addition to changing the Mercedes-Benz logo into the B logo, the wind resistance coefficient is also reduced. According to the official information given by Mercedes-Benz, the wind resistance of the EQS is as low as 0.20Cd. Although the official did not say how much the wind resistance coefficient was reduced after replacing with the carbon fiber kit specially designed for EQS, it only said that when the vehicle was traveling at a speed of 100 to 140Km/h, the battery life was increased by about 7%. Taking the EQS 450+ as an example, the officially announced WLTP battery life is 770km. After replacing the whole carbon fiber kit, the battery life increases by about 53.9 kilometers when the speed is between 100 and 140Km/h. These kits include carbon fiber front air dam trim, carbon fiber front lower spoiler, carbon fiber rear lower spoiler, carbon fiber three-dimensional rear spoiler, carbon fiber side skirts, and air pressure reduction modules. In addition, the original factory also launched an exclusive 22-inch Brabus Monoblock Z Platinum Edition forged aluminum ring, with Brabus SportXtra suspension system, the front suspension can be lowered by 15mm when driving, and the rear suspension can be lowered by 25mm, which is improved by lowering the center of gravity. driving dynamics. The changes in the car are not large, and the steering wheel has not been replaced. At present, only the interior-related trim panels are available. As for the power, it has been said before, and it is not in the scope of modification and upgrading.
