What is the heavy duty casting Brake drum for semi trailer and truck:

The truck and trailer brake drum, commonly known as the brake drum, is one of the more critical parts in the automobile brake system. It is the frictional part of the drum brake system. In addition to having the required strength and rigidity as a component, it also has a high and stable Wear resistance, heat resistance, heat dissipation and heat capacity, etc.

Brake drum types for reference:

Brake drum (2)

The brake drum is a type of cast iron shaped like a tambourine, which is fixed with the tire and rotates at the same speed. When braking, apply oil pressure to push the brake shoes to contact the brake drum inner rim, we can control the rotation of the wheel to achieve the purpose of braking by the friction force comes from contact.

Brake drum (4)

The brake drum is generally made of a special type of cast iron (gray iron HT250) that is heat-conductive and wear-resistant. Truck brake drum rotates with the wheel and axle. When a driver applies the brakes, the brake lining pushes radial force against the inner surface of the brake drum, and the ensuing friction slows or stops rotation of the wheel and axle, and thus the vehicle. This friction generates substantial heat.

Brake drum maintenance:

Due to the frequent braking of the car during driving, the brake drum is prone to alternating hot and cold, which is very easy to wear, crack and crack. Regular inspection and maintenance are very important. The following conditions must be repaired and replaced:

Brake drum (8)

1. The diameter of the brake drum exceeds the scrap size or although it does not exceed the scrap size, after cutting, the brake drum whose diameter exceeds the safe repair size should be replaced.

2. Brake drums with a taper or roundness error exceeding 155μm should be replaced.

3. When the friction surface of the brake drum changes due to the change of the metallographic structure caused by the braking heat, it should be replaced.

4. When there is any crack on the brake drum, it should be replaced

5. After the brake drum is cut, there must be no cracks and deformation, and its size must meet the requirements of the original manufacturer.
