SYSTEM DESIGN & DEVELOPMENT IN CALCULATION OF RESPONSE TIME FOR AIR BRAKE SYSTEM

INTRODUCTION:

COMPONENTS OF AN AIR BRAKE SYSTEM:

Air brake system consists of the following components:

Compressor:

The compressor generates the compressed air for the whole system.

Reservoir:

The compressed air from the compressor is stored in the reservoir.

Unloader Valve:               

This maintains pressure in the reservoir at 8bar.When the pressure goes above 8 bar it immediately releases the pressurized air to bring the system to 8-bar pressure.

Air Dryer:

This removes the moisture from the atmospheric air and prevents corrosion of the reservoir.

System Protection Valve:

This valve takes care of the whole system. Air from the compressor is given to various channels only through this valve. This valve operates only at 4-bar pressure and once the system pressure goes below 4-bar valve immediately becomes inactive and applies the parking brake to ensure safety.

Dual Brake Valve:

When the driver applies brakes, depending upon the pedal force this valve releases air from one side to another.

Graduated Hand Control Valve:

This valve takes care of the parking brakes.

Brake Chamber:

The air from the reservoir flows through various valves and finally reaches the brake chamber which activates the S-cam in the brake shoe to apply the brakes in the front

Actuators:

The air from the reservoir flows through various valves and finally reaches the brake chamber, which activates the S-cam in the brake shoe to apply the brakes in the rear.
