Introduction and Principle of Air Disc Brake/Clutch

Pneumatic air disc brake/clutch, also known as disc brakes, whichever shape suggests that it is named after. It consists of hydraulic control, the main components include a brake disc, wheel cylinders, calipers, tubing and the like. Brake discs with alloy steel and fixed on the wheel rotates with the wheel. Cylinder fixed on a stationary brake plate, brake caliper on two friction plates are mounted on both sides of the brake disc, wheel cylinder pistons by hydraulic tubing conveyed role in promoting the friction plate is pressed against the brake disc friction braking action up just like with pliers vise rotating plate, forcing it to stop the same. Disc brake heat dissipation, light weight, simple structure, easy to adjust. Especially high load high temperature performance, stable braking effect, and are not afraid of mud invasion, driving in the winter and bad road conditions, disc brakes make it easier to stop the car in a shorter time than drum brakes. On some disc brake rotor has opened a lot of holes, in order to accelerate and improve brake ventilation efficiency.

Disc brakes along the brake disc to apply force against the brake shaft moment, small radial dimension, braking performance and stability.
Disc brake structure type. Conventional disc brakes a little disc, the overall style and cone disc three.

Point Disc Brake

Since only a small portion of the friction surface of the brake disc, so that point disc. Fixed caliper floating caliper two. In order not to brake shaft by radial forces and bending moments, disc brake cylinder should point arranged in pairs. Braking torque is large, it can be multi-brake cylinder. If necessary, in the middle of the open air grooves to reduce friction temperature, heat insulation measures should be taken to prevent the deterioration of hydraulic oil temperature.

Complete Disc Brake
This brake compact structure, large friction area.
