• Specification

• Function

1.Providing friction for braking: The friction disc is an important part of the braking system. When the brake is applied, it generates friction with other components. By converting the kinetic energy of the machine into heat energy, it slows down or stops the moving machine, ensuring the safety during the operation of the equipment. For example, when a large - tonnage dump truck needs to stop, the friction disc plays a key role in the braking process.

2.Ensuring steering stability: In the steering system, the friction disc can cooperate with other parts to adjust the speed difference between the left and right wheels, enabling the machine to turn smoothly. It can provide appropriate resistance to ensure that the steering is stable and accurate, and prevent problems such as skidding or excessive steering during the steering process of the machine.
