Application

Application of air chamber2


The brake air chamber is a device composed of an air inlet, a cover, a diaphragm, a support plate, a return spring, a housing, a push rod, a connecting fork, a clamp, and a bolt.

The brake air chamber is also called the brake cylinder. The function of the brake air chamber is to convert the pressure of the compressed air into the mechanical force that makes the brake camshaft rotate to realize the braking action. It is the executive element in the automobile air brake system and an important safety part on the automobile.


1. According to the function classification, there are single air chamber and double air chamber. The front and rear brake chambers of the dual air chambers are of different sizes, but their structures are basically the same.

2. According to the structure classification, there are membrane type and piston type. The brake air chamber is clamp clamping diaphragm type.

Service Brake Chamber (T09/T12/T16/T20/T24/T30)

The service brake chamber is used when only the application of service brake air is required on an axle.

There will be no emergency braking provided on this axle.

You will find service brake chambers on steer axles, some rear axles, and old trailers that use a relay emergency valve to apply parking air pressure to the service chamber.


Spring Brake Chamber (T2024/T2424/T2430/T3030)

The spring brake chamber consists of the service brake and parking/emergency brake.

The service brake is the section at the clamp closest to the axle. The diaphragm, pushrod and return spring may be serviced by removing the clamp. The spring/emergency brake is everything from the first clamp to the end farthest from the axle. The spring brake must be completely replaced if it is faulty.
