[0002] The brake disc is a very important part in the car, because the brake disc is an indispensable part of the braking system. It can be said that the quality of a brake disc directly affects the safety performance of the entire car.

[0003] The brake disc also rotates with the car during operation. When braking, the brake caliper clamps the brake disc, so that the axle fixed on the brake disc also stops rotating. This is the principle of automobile braking, and the process of stepping on the brake is the process of the brake caliper clamping the brake disc;

[0004] In the prior art, most brake discs are made of rigid materials, and the entire brake disc is cast. When a brake disc is damaged, it needs to be directly replaced with another one, which causes material waste and is inconvenient for dispersed replacement. In addition, the existing brake discs are made of steel with a relatively smooth surface. The brake caliper needs to use a lot of force to clamp the brake disc, which is inconvenient for the brake caliper to clamp. Therefore, a new composite brake disc is proposed to solve the above problems. Utility Model Content
