Stainless steel car rear brake drum: Stainless steel
The brake drum is the main component of the drum brake system. The friction between the inner surface of the brake drum and the brake pads during braking acts as a brake. The brake drum is a cast iron piece shaped like a tambourine, which is fixed to the tire and rotates at the same speed. When braking, oil pressure is used to push the brake shoes to contact the inner edge of the brake drum, and the friction generated by the contact is used to suppress the rotation of the tire to achieve the purpose of braking.
1、Anti-corrosion anti-wear.
2、High coefficient of friction.
3、Bearing capacity is strong.
4、Emergency stop brake,refuse to shake, high stability coefficient.
5、High temperature resistance, long life.
6、Good heat dissipation performance.
The brake drum is an important component of the drum brake system. The inner surface of the brake drum of the drum brake is where the braking device generates a braking torque. With the same braking torque, the diameter of the brake drum of a drum brake device can be much smaller than that of a disc brake. Therefore, in order to obtain a powerful braking force, a large vehicle used for loading can only install a drum brake in a limited space of a rim.
The brake drum have sufficient wall thickness, and cast circumferential or axial stiffeners on the outer surface near the opening to improve strength. These stiffeners also play a role of heat dissipation, which can reduce the temperature of the friction surface, shorten the brake cooling time.
