Description

Efficient heat dissipation brake disc

technical field

The utility model relates to a wheel brake mechanism, in particular to a brake disc.

Background technique

The brake disc is used to brake the wheel. During the working process, the friction surface of the brake disc contacts the side of the wheel and decelerates the wheel through friction. The friction between the brake disc and the wheel causes the brake disc to generate a large amount of heat. In the prior art, the brake disc has a cake-shaped overall structure, and the heat accumulates in the cake-shaped overall structure. The heat dissipation effect is poor, which causes the brake disc to deform and cause danger.

Contents of the invention

The purpose of the utility model is to provide a brake disc that can improve the heat dissipation effect in view of the deficiencies in the prior art.

The high-efficiency heat dissipation brake disc provided by the utility model includes a brake disc body and at least two layers of heat dissipation outer edges arranged on the side of the brake disc body. A gap is provided between the heat dissipation outer edges of the layers.

Compared with the prior art, the beneficial effects of the utility model are:

The high-efficiency heat dissipation brake disc provided by the utility model includes a brake disc body, and at least two layers of heat dissipation outer edges are arranged on the brake disc body, and the heat generated by the brake disc body during braking can be transferred to each layer of heat dissipation outer edges. There is a gap between two adjacent heat dissipation outer edges, and the heat dissipation outer edge realizes heat dissipation through heat exchange with air, thereby reducing the heat accumulated in the brake disc body, thereby improving the heat dissipation effect of the brake disc.
