Description

Technical Field

[0001] The utility model relates to the technical field of disc brake discs, in particular to a disc brake disc with good heat dissipation performance. Background Art

[0002] The disc brake, commonly known as the disc brake, is a very important component in the braking system. It is a brake disc connected to the wheel. The disc brake disc rotates with the wheel when the car is driving. When braking, the high-pressure brake oil pushes the brake pad, and the friction between the brake pad and the disc brake disc plays the role of slowing down or stopping the car. The potential energy of friction is eventually converted into heat energy, which is bound to make the brake disc withstand high temperatures. Based on the limitations of material properties and processes, the disc brake disc can only be equipped with various heat dissipation holes to increase the surface area and improve the heat dissipation efficiency. This method has the disadvantage that the heat dissipation efficiency is difficult to improve. When the outer ring of the disc brake disc is subjected to high heat, the inner ring of the disc brake disc contacts the heat. Under long-term heating conditions, the disc brake disc is squeezed by the brake pad and easily twisted and deformed.
