Parking brake chamber is a brake device with spring energy storage and air release. The charging pressure enters the pressure chamber from 12 ports and produces the force acting on the piston. When the pressure is greater than 0.65Mpa, the force acting on the piston is greater than the pre-tightening force of the spring. The piston goes up to the limit and the brake is removed. If the air in the pressure chamber is completely emptied, the spring pushes the piston down and pushes the push rod of the main brake to generate braking, and the braking strength is related to the spring pretightening force. When the pressure of the pressure chamber is lower than 0.65MPa, the braking force produced by the chamber is inversely proportional to the pressure value, so emergency braking can be implemented.
