Description

Technical Field

[0001] The utility model relates to the field of dry brakes, in particular to a dry brake capable of accelerating temperature reduction. Background Art

[0002] A dry brake generally includes a wheel hub, which is provided with a plurality of through holes, in which friction materials are embedded, and an annular friction disc is provided on both sides of the friction materials, and the friction disc is coaxially arranged with the wheel hub. When braking, the friction disc and the friction material rub against each other, and finally the wheel hub braking is achieved by means of the friction between the two. When the existing dry brake is working, the brake pad and the brake disc are wrapped on the inner side of the shell. Based on the working principle of the dry brake, a large amount of heat is generated after the friction between the brake pad and the brake disc. The wrapping of the shell makes the heat dissipation effect of the dry brake very poor. When the temperature of the brake pad and the brake disc is high, the braking effect of the dry brake will be deteriorated, which reduces the safety of the vehicle after frequent braking.

[0003] Therefore, it is necessary to invent a dry brake that can accelerate cooling. Utility Model Content
