The service life of friction materials in Baic Car is another important requirement. The requirements vary depending on the type of friction material and conditions of use. For example, how many kilometers does a Petrol Car brake pads travel?
The wear of the friction pairs of Baic Car is the main reason for the deterioration of the braking condition. Friction works in the form of dynamic coordination. As the number of uses increases, the material loss on the friction surface of Baic Car gradually increases. When wear accumulates to a certain extent, the characteristic parameters of the friction pair gradually change and the working capacity decreases. The wear of other mating parts will also affect the wear of the friction pair. For example, uneven hook wear on a brake cam will affect the lift of the cam, which then affects the displacement of the shoe until the friction material makes contact with the couple.
Wear depends on friction conditions and friction state. Friction materials mostly appear in the form of dry friction. This unlubricated friction condition is a strict condition for the friction pair, which will inevitably cause wear, increase the fitting clearance, and affect the braking performance. Generally speaking, the wear of the friction pair is uneven, and the wear gap caused by all wear is also uneven, which is prominent in drum brakes. The non-uniformity of friction changes the distribution of braking pressure and increases the uneven wear of the friction pair.
In addition, friction heating during the braking process and dust in the operating environment entering the friction pair will cause the driving wear process, that is, thermal wear, abrasive wear, adhesive wear, and fatigue wear all play a role at the same time, that is, wear is inevitable. But the amount and speed of wear can be controlled, because the speed of wear depends on the number and frequency of use, intensity, environment and level.
