Bus Brake Linings

Buses is any type of motor vehicle used for transporting goods or paying passengers. Baiyun develops and manufactures drum brake linings for buses including truck & bus which require powerful braking force.

For large buses, strong braking forces are required. To this end, drum brakes linings are widely used because they are more lightweight and costs less that disc brakes, while capable of delivering more braking force.

Drum Brake Linings for Buses

Drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. Drum braking linings have brake drums that rotate with the wheels.

Brake shoes fitted with drum brake linings (friction material) which press against the drums from the inside to generate braking force (decelerate and stop) are set inside of the drums.

With this system, friction is generated by pressing the brake linings against the inside surfaces of the drums. This friction converts kinetic energy into thermal energy. Drum rotation helps to press the shoes and the lining against the drum with more force, offering superior braking force in comparison with disc brakes. On the other hand, it is very important to design the components so that the heat from the thermal energy is dissipated efficiently into the atmosphere.

There are three types of drum brakes depending on how the brake shoes are pressed on to the drums; leading/trailing shoe type, twin leading shoe type and duo-servo type.

Structure of drum brakes

Drum brakes are a brake system with brake drums (rotor) which rotate with the wheels. Inside each drum are brake shoes fitted with brake linings (friction material). Pistons (pressure mechanism) press against the drums from the inside to generate braking force, thus making is possible to decelerate and stop the vehicle.
