Working of Air Braking System :
When the brake pedal is pushed the brake valve opens and compressed air is allowed into the brake chamber.
The brake valve consists of three passages.
1. Air intake
2. Exhaust
3. Brake chamber
When the brake pedal is pressed the exhaust passage will be closed and Air intake passage open and compressed air goes back to the chamber. During return stroke the exhaust passage opens while intake closes and used air goes to the atmosphere. This system fitted with an emergency mechanical brake, which can be used when air supply fails the air brake system, which is called an air-assisted hydraulic braking system.
Working principle:
As shown in the figure, in the air brakes the compressed air (around 700 kPa) is used to actuate the brake mechanism. The figure shows the complete layout of the Air Brake System. It consists of Air filter, unloading valve, Air compressor, Air reservoir, Brake valve, and 4 numbers brake chamber. The compressor takes atmospheric air through the air filter and compresses the air. This air is stored under pressure in the air reservoir. From this reservoir air goes to various accessories of the vehicle which operates on compressed air. Part of the air goes to the brake valve. The control of the brake valve is done by a driver who controls the intensity of braking according to an emergency.
Pedal Depressed: When the brake pedal is depressed, compressed air from the reservoir is transmitted through pipes equally in all directions to the brake chambers through brake valve which further applies the brake.
Pedal Released: When the driver releases the brake pedal, the master cylinder piston returns to its original position due to return spring, and the pressure is dropped. It releases brake shoes from brake drum to their: original position and brakes are released.
