The brake drum, also commonly referred to as the brake drum, is an important part of the vehicle's braking system. It is installed on the wheel hub and works closely with the vehicle's brake pads, together equivalent to the structure and For Shaanxi Automobile Trucks, the role of the rear brake drum is extremely critical.

The main functions of the rear brake drum include the following:
1. Conversion function: When the vehicle is driving, the wheel rotation drives the brake drum to rotate. When the brake system is activated, the brake drum converts the rotational motion of the four wheels to interrupt the heat energy through the friction with the brake pad, thereby achieving the purpose of blocking and stopping.
2. Providing friction: The inner surface of the brake drum is specially treated to provide sufficient friction. This friction responds to the brake pad during braking, ensuring that the vehicle can stop quickly and smoothly.
3. Evaporation effect: Since a large amount of heat is generated during braking, the design of the brake drum is conducive to the transfer of heat. The special materials and structures enable the heat to be quickly transferred and transported to the air, avoiding overheating and damage to the brake system
4. Stability and safety: The working state of the rear brake drum directly affects the braking performance and driving stability of the vehicle. A good brake drum can ensure that the vehicle can achieve effective braking at high speeds, heavy loads or complex road conditions, thereby improving the safety of the vehicle.
