What does air brake mean?

Air brake is a braking method relative to oil brake, and also a braking system, mainly used in medium and large-sized vehicles, characterized by rapid response, harsh braking, and strong force. The information about air brake is as follows: Components: It consists of brake operating mechanism, dual-circuit braking mechanism, brake, air compressor, etc. Among them, the brake operating mechanism includes brake pedal, pedal hanger, manual brake valve, etc.; the dual-circuit braking mechanism includes air reservoir, brake valve, low-pressure alarm, air pressure regulator, brake pipe, directional valve, relay valve, safety valve, and drain valve. Working principle: The parking brake system of this type of vehicle normally uses a powerful spring to maintain the braking state. When the vehicle needs to move, the driver releases the parking brake by performing an air charging action. A certain air pressure must be reached to push open the spring, which means releasing the parking brake before the vehicle can move. In conventional braking, the parking brake locks the drive shaft, while the foot brake uses compressed air to enter the brake chamber to lock the wheels.
