Abstract

The invention relates to the field of vehicle braking systems, and discloses a three-cavity spring braking gas chamber. The three-cavity spring braking gas chamber comprises a cylinder body, a connecting base and a fixing base. A spring cavity is formed in the cylinder body. A membrane cavity is formed between the connecting base and the fixing base. A relief piston is further connected with the interior of the cylinder body in a sliding mode, and a remote control forced relief cavity is formed between the relief piston and the connecting base. A communicating opening which is used for communicating with the external gas is formed in the connecting base. By the adoption of the scheme, the forced relief can be relatively conveniently achieved, and the parking braking operation can also be normally applied after the forced relief is accomplished.

Description

technical field [0001] The invention belongs to the field of vehicle brake systems. Background technique [0002] The spring brake air chamber is widely used in the car brake system and is installed on the drive axle of the car to provide braking force for the car. It is mainly composed of two parts: the diaphragm cavity is used for service braking; the spring cavity is used for auxiliary braking and parking braking, and a mechanical relief mechanism is provided to realize forced relief. [0003] With this kind of brake chamber, when the brake fails to be released normally, the driver and passengers need to get off the car, manually screw the screw with a tool, unscrew the screw and compress the parking brake spring to achieve forced relief, which is inconvenient to operate. And the parking brake can no longer be applied normally after the forced release. Contents of the invention [0004] The object of the present invention is to provide a three-chamber spring brake air...
