In the automotive industry, the brake air chamber of the car is also called the brake cylinder of the car. Its function is to convert the pressure of the compressed air into a mechanical force, which can drive the rotation of the brake camshaft, and finally achieve the braking action. How does a car's brake chamber work?
The components of the brake air chamber mainly include the air inlet, the shell, the diaphragm, the cover, the support disc, the bolt, the push rod, the clamp, the return spring and so on. When the car is braked, the air can enter the brake air chamber through the air inlet, at this time the diaphragm begins to deform due to the air pressure, and then pushes the push rod, and at the same time drives the brake adjustment arm to rotate the brake cam , and finally realize the braking of the car. In the same way, it is not difficult to understand, how can the brakes of the car be released? It only needs to exhaust the air in the brake chamber to the atmosphere, and the diaphragm and push rod return to their original positions, and it can be achieved.
Our more common brake chambers include diaphragm type, piston type and composite type. The diaphragm type brake air chamber is separated by a diaphragm to make it in two different spaces, and the connecting fork and the brake adjusting arm are connected together.
