Structural characteristics and usage of spring brake chamber

The spring brake air chamber is composed of two independent diaphragm air chambers, which are independently operated by the service brake and the parking brake or the emergency brake components. It is used to provide braking force for the wheels. When braking, compressed air enters cavity a through port 11, acts on diaphragm b, compresses spring c, push rod d pushes out, the pressure acting on diaphragm acts on the adjusting arm through the connecting rod, and it exerts on the wheel Braking torque. When parking and emergency braking, the manual control valve makes the compressed air of E cavity completely or partly released through port 12, and the energy storage spring g also releases energy completely or partly, through the diaphragm f, push rod kd and brake The adjusting arm acts on the wheel brake. When driving normally, put the loose bolt h in hole A and tighten it with a nut. When mechanical loosening is required, put the loose bolt in the trayi, rotate it 90 degrees, and then unscrew the loose bolt to realize manual connection without compressed air. Except for braking.
