Pneumatic braking systems utilize compressed air as the power source for braking.
Features: Easy braking operation, strong braking force, short pedal travel; however, it consumes engine power; braking is relatively abrupt and the structure is relatively complex.
Applications: This type of pneumatic braking system is commonly used in heavy-duty trucks and some medium-sized vehicles.
The main components are an air compressor, brake chamber, air reservoir, pressure regulating valve, and brake control valve.
Air Compressor: Driven by the engine via a drive belt, gears, or directly using a camshaft.
Brake Chamber: Converts the pressure from the air reservoir into the mechanical force that rotates the camshaft.
Air Reservoir: Pressure Regulator: Adjusts the compressed air pressure in the air reservoir, maintaining it within a specified range.
Brake Control Valve: Controls the working pressure in the brake chamber, allowing for changes and automatic adjustment.
