Double Diaphragm Spring Brake Chamber And Combined Spring Brake Chamber

Double diaphragm spring brake chamber

Several typical uses:

The double-diaphragm spring brake air chamber is composed of two independent diaphragm air chambers, which are operated independently by the service brake and parking brake or emergency brake elements, which are used to provide braking force for the wheels.

working principle:

1. When braking, the compressed air enters chamber a through 11: it acts on the diaphragm b and e compresses the elastic tube & n the push rod d is pushed out, and the pressure acting on the diaphragm acts on the adjustment arm through the connecting rod. The wheels generate braking torque.

2. During parking and emergency braking, the manual control valve releases the compressed air in chamber E completely or partially through port 12, and the energy storage spring g also completely or partially releases energy, through the diaphragm f, push rod kd and The brake adjustment arms act on the wheel brakes.

3. When driving normally, put the loosening bolt h in the hole A and tighten it with nuts. When mechanical loosening is required, put the loosening bolt into the tray i, rotate it 90 degrees, and then unscrew the loosening bolt to realize no compressed air. Remove the brake manually.

Combined spring brake chamber

Purpose: The combined spring brake air chamber is used to provide braking force for the wheels. It consists of two parts, the diaphragm brake part is used for driving brake, the spring brake part is used for emergency brake and parking brake, and the spring The brake part and the diaphragm brake part work completely independently.

working principle:

During the service braking, the compressed air from the foot brake valve enters the chamber A through port 11, acts on the diaphragm, and compresses the spring C to push the piston e out, and the force acting on the diaphragm d acts on the diaphragm d through the push rod b. On the brake adjusting arm, a braking torque is generated on the wheel. During parking braking and emergency braking, the hand brake valve makes the compressed air in chamber B pass through port 12 to fully or partially release its energy, and generate braking torque on the wheel through piston e, push rod b and brake adjustment arm . Unscrewing the loosening bolt g can mechanically loosen the parking brake part, which is used to manually disconnect the brake without compressed air.
