Comparison between single chamber brake chamber and double chamber brake chamber.-Anshang Vehicle Parts (Jiaxing) Co., Ltd.

Single chamber brake chamber:

Purpose: to provide braking force for wheels

Working principle: the pressure from the air chamber acts on the diaphragm, and the diaphragm and piston move to the right. The piston is transmitted to the brake rod (clearance adjusting arm) through the push rod, and then to the brake. When the brake chamber is vented, the spring returns the piston and diaphragm to its original position. The acting force of the diaphragm air chamber depends on the acting force of the diaphragm and the effective acting area of the diaphragm. The effective working area of the diaphragm changes with the bending amount of the diaphragm.

Dual chamber brake chamber:

Purpose:

Used to generate braking force for wheels. The diaphragm part is used for service braking, and the spring part is used for auxiliary and parking braking.

Working principle: during service braking, compressed air enters the first chamber through the air inlet, acts on the diaphragm, overcomes the right movement of the compression spring, and the generated braking force acts on the clearance adjusting arm to brake the wheels. When the pressure in the second chamber decreases, the compression spring will push the diaphragm and push plate back
