[0002] The brake system is an important component on the automobile, which comprises a disc brake and a drum brake, and the disc brake realizes braking through the cooperation of a brake disc and a friction plate on a caliper.

[0003] During braking, the friction plate and the disc surface of the brake disc rub against each other, generating a large amount of heat, and 95% of the heat energy will be absorbed by the brake disc. If the braking frequency is high, the temperature of the brake disc will continue to rise (may exceed 600℃). The excessively high temperature of the brake disc will cause the following safety hazards:

[0004] 1. The brake disc itself is insufficient in strength, and under high temperature conditions, the brake disc is prone to cracking and other failures.

[0005] 2. The friction pair effect of the brake disc and the friction plate will be reduced (the friction coefficient of the friction plate will decrease sharply under high temperature), and the braking effect of the whole vehicle will be reduced, which may cause the vehicle to be unable to stop.

[0006] 3. The excessively high temperature will accelerate the wear of the friction plate and the brake disc, and reduce the service life of the brake disc and the friction plate.

[0007] At present, the brake of a conventional vehicle on the market generates a large amount of heat during braking, and the heat dissipation is slow, which leads to a high temperature of the brake and reduces the braking efficiency. INVENTION CONTENTS
