What is the working principle of the brake chamber?-Anshang Vehicle Parts (Jiaxing) Co., Ltd.

The brake air chamber shell and cover are made of steel plates and connected together by clamps and bolts to form the whole shell. A rubber diaphragm is installed between them. The diaphragm separates the whole shell into two completely isolated air chambers. The air chamber between the diaphragm and the cover is connected to the double chamber brake valve, and the air chamber between the diaphragm and the housing is usually connected to the atmosphere. In the free state, the diaphragm is close to the cover plate, and the other side is in contact with the disc on the push rod. A return spring is installed between the disc and the end face in the housing, and a connecting fork is installed at the other end of the push rod to connect the brake adjusting arm. The entire brake chamber is bolted to a special bracket.

When the vehicle is released from braking, the compressed air in the brake chamber is discharged into the atmosphere through the double chamber brake valve or quick release valve, and the diaphragm and push rod return to their original state under the action of the return spring. When the vehicle is braked, air enters the brake air chamber from the air inlet. Under the action of air pressure, the diaphragm deforms, pushes the push rod, drives the brake adjusting arm, rotates the brake cam, and presses the brake shoe friction plate against the brake drum to generate braking.
