Brake drum with radiating rib structure

Abstract

A brake drum with a radiating rib structure comprises a brake drum body shaped like a cylinder, a boss arranged in the brake drum body in the peripheral direction, a dust cover which is installed in the brake drum body in an inserted mode and makes contact with the boss and multiple radiating ribs which are arranged at the tail end of the outer side of the boss in the peripheral direction. Each radiating rib is of a long-strip-shaped structure, and the radiating ribs are arranged in the axis direction of the brake drum body. By means of the radiating ribs, the radiating area of the brake drum is significantly increased; meanwhile, the tail end of the brake drum is completely exposed in the air, and good air motion can be formed at the tail end by means of rotating of the brake drum in the running process; by means of the strip-shaped radiating ribs, air motion is effectively accelerated, heat produced during the braking process of the brake drum body 1 can be efficiently and smoothly radiated, the heat fading effect of a braking system is effectively avoided, and the safety of braking is guaranteed. In addition, the dust cover is matched with the brake drum body for use on the inner side of the barrel-shaped drum wall through the boss, foreign matter such as sand dust and liquid is effectively blocked from entering, and the protective effect is better.

Description

technical field [0001] The invention relates to a brake drum with a cooling rib structure. Background technique [0002] The brake drum is an important part of the drum brake, and the performance of the brake drum directly determines the braking performance. During the braking process, the brake drum will generate heat due to brake friction, especially on vehicles that require frequent braking or long-distance braking in mountainous areas or mining areas. The high temperature of the moving drum will affect the braking performance. At present, the method of installing water spraying device on the surface of the brake drum is generally used to dissipate heat from the brake drum. Although water spraying on the outer surface of the brake drum can reduce the temperature of the brake drum, it will also cause the inner wall and outer surface of the brake drum to generate heat. The sharp temperature difference may cause the phase change stress of the brake drum, which will lead to...

Problems solved by technology

At present, the method of installing water spraying device on the surface of the brake drum is generally used to dissipate heat from the brake drum. Although water spraying on the outer surface of the brake drum can reduce the temperature of the brake drum, it will also cause the inner wall and outer surface of the brake drum to generate heat. Sharp temperature difference, which may cause phase change stress in the brake drum, and then lead to cracks in the brake drum

In addition, due to the structural characteristics of the brake drum and the limitation of space layout, it is difficult to implement the solution of adding heat dissipation ribs on the front end surface of the brake drum or outside the friction surface, and the front end of the brake drum goes deep into the tire, and together with the tire Rotating too fast, the air flow in the front end is not ideal
