Uses: The combined spring brake air chamber is used to provide braking force to the wheels, it consists of two parts, the diaphragm brake part is used for service braking, the spring brake part is used for emergency braking and parking brake, and the spring brake part is used for emergency braking and parking brake. The braking part and the diaphragm braking part work completely independently.
When the service is braked, the compressed air from the foot brake valve enters the A cavity through the 11th port, acts on the diaphragm, and compresses the spring C to push out the piston e, and the force acting on the diaphragm d acts on the diaphragm d through the push rod b. On the brake adjustment arm, a braking torque is applied to the wheels. During parking braking and emergency braking, the hand brake valve makes the compressed air in the B cavity fully or partially release its energy through 12 ports, and generates braking torque on the wheels through the piston e, the push rod b and the brake adjustment arm. . Unscrew the loosening bolt g to mechanically loosen the parking brake part, which is used to manually connect and remove the brake in the absence of compressed air.
