Technical Field
The utility model relates to the technical field of brake drums, in particular to a wear-resistant automobile brake drum.
Background
In automotive braking systems, drum brakes are a low cost, simple maintenance type of brake. The brake drum is a core component of the drum brake, and plays a role in converting kinetic energy of the whole vehicle into thermal energy to be stored and emitting the thermal energy into air. The heat dissipation capability is one of the most important performances of the brake drum, otherwise, the brake drum temperature is too high to cause extremely reduced braking efficiency, and the braking safety of the whole vehicle is affected. The friction between the inner wall of the brake drum and the brake pad produces braking effect, and heat is generated in the friction process, so that the temperature of the brake drum is increased, and especially, more heat energy is generated during long-time braking. In the use process of the traditional brake drum, the inner wall of the drum body of the traditional brake drum often has too high abrasion rate, so that the frequency and cost for replacing the brake drum are increased, and the cooling effect of the traditional brake drum is poor, for example, the brake drum is watered and cooled, and burst is easy to generate. For this purpose, wear-resistant motor vehicle brake drums are proposed.
