What are the classifications of brake drums?

Brake drum is the friction coupling of drum brake, in addition to the strength and stiffness required as a component, but also should be as high and stable friction coefficient as possible, as well as the appropriate wear resistance, heat resistance, heat dissipation and heat capacity.

Brake drum classification

The basic shape of the brake drum is drum, and there is a connecting hole on the mounting surface.

Monolithic casting type

Brake drum is made of high strength gray cast iron or alloy cast iron containing Cr. This kind of brake drum has simple structure, convenient processing, large heat capacity, but large mass, and is mostly used for medium and heavy duty vehicles.

Combined steel plate and cast iron

Brake drum by steel plate stamping drum and cast iron drum ring two parts of a body, the mass is small, used for cars and light vehicles.

Combined light alloy and cast iron

Brake drum body is light alloy material (such as aluminum alloy, etc.), lined with cast iron lining ring. This kind of brake drum is not only of small quality, but also of good heat dissipation. It is mostly used for cars.
