1.What is air brake compressor?

An air brake compressor is a mechanical device used in vehicles, particularly in heavy trucks and buses, to compress and supply air to the air brake system. This compressed air is stored in reservoirs and used to actuate the brakes, ensuring safe and effective stopping power.

2.How do compressed air brakes work?

A. Compressed air brakes, commonly used on heavy trucks, buses, and trains, operate through the following process:

B Air Compression: An engine-driven compressor generates and pumps compressed air into the storage tanks (air reservoirs).

C.Reservoir Storage: The clean, dry compressed air is stored in air reservoirs until needed.

DBrake Application:

Brake Pedal: When the driver presses the brake pedal, a valve (known as a brake valve or foot valve) is activated.

Control Signal: This action sends a control signal to the brake chambers, relaying compressed air to the brake actuators.

Brake Actuators: The brake actuators (also called brake chambers) use the air pressure to push a diaphragm or piston, converting the air pressure into mechanical force.

Brake Mechanism Activation:

Drum Brakes: In drum brakes, this mechanical force pushes the brake shoes against the drum, creating friction and slowing the vehicle.

Disc Brakes: In disc brakes, it presses brake pads against the rotor discs, generating friction and decelerating the vehicle.

Release: Releasing the brake pedal causes the control valve to exhaust the air from the brake chambers back into the atmosphere, allowing the return springs to retract the brake shoes or pads, and thus releasing the brakes.

System Protection: Safety devices like pressure relief valves and low-pressure warning systems ensure the system operates within safe parameters.

Throughout this process, the air pressure in the system is continuously monitored and regulated to ensure effective and safe braking under various operating conditions. Regular maintenance of the air brake system is crucial to ensure its reliability and performance.
