Everyone knows that no matter what the car, especially the vehicle, the regulations on braking are relatively high, and the speed of the vehicle is fast. If the actual effect of the braking is not good, it is very easy to cause a road traffic accident, so everyone Do you know what are the factors that endanger the braking performance of vehicles? The most important thing is the friction plate, so if it must be dismantled and replaced, it must be of good quality to ensure safety. So, do you know what factors should be considered when buying friction plates? Let me explain to everyone below.
Factors that endanger the braking performance of vehicles:
The first thing I think of must be the friction plate, because people usually touch and hear a lot, and the frequency of disassembly and replacement is also very much. The whole process of braking is the whole process of two friction plates clamped to the brake disc, causing sliding friction between them and reducing the speed. Therefore, the pros and cons of the raw materials of the friction pads and brake discs, and the size of the friction resistance, will immediately harm the pros and cons of the braking performance.
Car brake friction linings The porcelain friction linings used on high-performance super sports cars, carbon fiber material porcelain brake discs, etc., have high friction resistance, small heat decay, and short brake spacing. There is also the total number of piston rods of the brake master cylinder. A common car has only one piston rod for a brake master cylinder. In a performance car, there will be two or three piston rods. This will promote the energy of the friction plate to be large and symmetrical. Hazard braking performance.
Secondly, tires are also a critical factor that compromises braking performance. Since the sliding friction of the two friction pads and brake discs is not good enough, the sliding friction between the tires and the road surface is necessary in order to have the braking effect. Generally, the wider the tire, the larger the total contact area with the road, the better the raw materials, the more effective the layout of the texture, the greater the frictional resistance with the road, the greater the sliding friction caused, and the better the actual braking effect. Therefore, in order to improve the actual effect of braking, in addition to the friction lining, the tire is also a factor that cannot be ignored.
There is also brake fluid. Brake fluid cannot be reduced and is used to transmit braking force. The temperature caused by brake friction is high. The brake fluid can ensure that it does not vaporize. It can also ensure sufficient circulation when the temperature is low in winter. Therefore, the brake fluid that meets the standard is very important.
Factors that must be considered when choosing a friction plate:
When choosing a friction plate, you must consider the packaging, color, surface, paint, material, processing technology, storage, tight connection, logo, and whether there are errors or omissions. The following is a detailed introduction:
The packaging of the original parts of the friction plate of the reducer is generally relatively standard, with a unified standard specification and model, and the hot stamping handwriting is clear and reliable. The printing and packaging of fake and inferior products is relatively rough, and it is usually very easy to find loopholes in the packaging.
Some original parts have a specific color on the surface. If they meet other colors, they are fake and inferior parts.
The surface of the original parts is hot stamped or cast and marked clearly and reliably, while the appearance of the fake and inferior products is not smooth.
Illegal businessmen take the waste parts through simple production and processing, such as disassembly, assembly, assembling, assembling, painting, etc., and then selling counterfeit qualified products, illegally making huge profits.
The raw materials of the original parts are selected according to the design plan. The fake and inferior products are mostly replaced by cheap and inferior raw materials.
6. Processing technology
Although the appearance of fake and inferior goods is sometimes very good, it is very prone to cracks, sand holes, weld bumps, burrs or knocks due to poor processing technology.
If the friction plate has problems such as cracking, air oxidation, discoloration or embrittlement, it is likely to be caused by poor natural environment, long storage time, and poor raw materials during storage.
8. Tightly connected
If the friction plate bolts are loose, the glue is opened, the joints of household appliances parts are welded, and the interface of the paper filter element is loosened, it cannot be applied.
Some reliable parts are marked with some marks. Pay attention to the production license and specific friction resistance marks on the selection package. The quality of products without these two marks is difficult to ensure.
10. Errors and omissions
Reliable total process components must be intact and undamaged to ensure smooth installation and normal operation. Some small parts on some general parts are rarely installed, usually "parallel import mobile phones", which causes difficulties in installation. Usually, due to the shortage of some small parts, all the total distance components are damaged.
The above is a detailed explanation of the factors that endanger the braking performance of vehicles and the factors that must be considered when choosing friction linings. When buying friction linings, everyone can refer to the above method and look forward to helping everyone.
