Abstract

Provided is a high-performance ternary compound brake pad. A brake pad body is formed by a pre-friction region, a main friction region, and a heat radiation region. The pre-friction region has a proper friction coefficient, and brake performance is good and does not scratch a brake disc. The pre-friction region is on the forefront of the brake pad body, and through certain degree abrasion, an excellent frictional layer and a transfer film are formed, so as to play good pre-friction role, and lays foundation for high-efficiency operation of the main friction region. The main friction region is composited by a plurality of kinds of new fiber materials, and the materials make up defects of respective performance and have high performance caused by mutual dragging effect. In a brake process, highest temperature reaches 380 DEG, and the brake pad would not change the friction coefficient and wear rate, and the brake pad would not have cracks when the brake is slammed. The heat radiation region ensures advantages of each material to be fully developed in the friction material through rational matching of various components. The temperature resistance of the heat radiation region is good, and the heat radiation region has good heat stability and relatively low heat conduction force, and satisfies 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 high-performance ternary composite brake pad. 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...
