Fast heat dissipation motor vehicle brake disc

Abstract

The invention discloses a fast heat dissipation motor vehicle brake disc which comprises an installation disc. The outer side wall of the installation disc is provided with an upper brake disc and a lower brake disc through a bolt. Multiple supporting assemblies are symmetrically arranged between the upper brake disc and the lower brake disc. Multiple sets of heat dissipation through holes are symmetrically formed in disc bodies of the upper brake disc and the lower brake disc, and multiple arc grooves are symmetrically formed in the upper surface of the upper brake disc. The fast heat dissipation motor vehicle brake disc is simple in structure and high in practicability, the braking performance of a motor vehicle is improved in rainy days or the motor vehicle passes through puddles of water, in addition, the heat dissipation rate of the brake disc is increased, and traffic accidents caused by the high-temperature recession phenomenon of the brake disc are avoided.

technical field [0001] The invention relates to the technical field of brake devices, in particular to a fast heat dissipation motor vehicle brake disc. Background technique [0002] The brake disc is a very important part of the braking system. When the brake is stepped on, the brake disc clamps the brake disc and relies on the friction between the two to perform the braking effect. The internal polymer compound will be thermally decomposed due to frictional heat. Under the condition of poor exhaust, it is easy to form an air cushion film on the surface of the brake disc, which will reduce the high-temperature friction coefficient and cause high-temperature recession. [0003] Existing drum brakes or solid disc brakes are difficult to achieve rapid heat dissipation. Although the heat dissipation holes on the solid disc brake are helpful for the heat dissipation of the brake disc, a small number of heat dissipation holes have no obvious heat dissipation effect, and the heat ...

[0002] The brake disc is a very important part of the braking system. When the brake is stepped on, the brake disc clamps the brake disc and relies on the friction between the two to perform the braking effect. The internal polymer compound will be thermally decomposed due to frictional heat. Under the condition of poor exhaust, it is easy to form an air cushion film on the surface of the brake disc, which will reduce the friction coefficient at high temperature and cause high temperature recession.

[0003] Existing drum brakes or solid disc brakes are difficult to achieve rapid heat dissipation. Although the heat dissipation holes on the solid disc brake are helpful for the heat dissipation of the brake disc, a small number of heat dissipation holes have no obvious heat dissipation effect, and the heat dissipation holes are too dense. It will reduce the strength of the brake disc and cause potential safety hazards. Therefore, we propose a fast heat dissipation motor vehicle brake disc
