Abstract

The invention discloses a composite brake pad with stable performance. A brake pad body consists of a pre-friction region, a main friction region and a heat dissipation region, wherein the pre-friction region has a proper friction coefficient, is high in braking performance and cannot scratch a brake flange; the pre-friction region is located at the forefront part of the brake pad body, can form an excellent friction layer and a transfer film through wear to a certain extent, and achieves a good pre-friction effect, so that a foundation is laid for efficient work of the main friction region; the main friction region is compounded by various new fiber materials; the multiple new fiber materials can complement the respective performance shortcomings and also carry out mutual traction action to generate high performance. In a braking process, the highest temperature can be up to 380 DEG C, the friction coefficient and the wear rate of the brake pad cannot be changed, and no cracks appear under sudden braking; the heat dissipation region carries out reasonable matching on various components to ensure that the advantages of all the materials can be fully developed in a friction material, is high in temperature resistance, high in thermal stability and relatively low in heat conductivity, and meets the technical requirements of high wear resistance, high speed and safety of the brake pad.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a composite brake pad with stable performance. Background technique [0002] Today, with the rapid development of the automobile industry, the safety and environmental protection of vehicles are particularly important, and people's new requirements for automobile brake pads are constantly increasing. Automobile brake pads are subjected to external pressure to generate friction during work, so that the vehicle can achieve the purpose of deceleration. Therefore, the wear resistance and heat resistance of the material of the brake pad are very important. In addition, the friction materials used in the automobile brake pads we use now contain many heavy metal substances, including antimony, chromium, cadmium, copper, barium, copper and other heavy metals. Every time a car brakes, a small amount of heavy metal dust is released and accumulated in the environment, causing harm. For example,...
