Abstract

The invention discloses a diaphragm type spring braking chamber of a truck braking system, wherein a one-way valve is arranged in an inner hole of the contact position of a piston rod of an energy storage piston (13) and a diaphragm and comprises a one-way valve plug screw (8), a valve seat (11), a rubber valve (12) and a one-way valve opening (14) are arranged on the one-way valve plug screw (8), and the valve seat (11) is axially fixed through a hole baffle ring (9). By adopting the technical scheme, the traditional parking braking cavity respiration structure is improved, the cost is reduced, the property is improved, a dust collecting device of the product is additionally arranged, therefore, the reliability, the dustproof performance, the durable performance and the like of the product are improved, the service life is prolonged; and the product structure is simplified and the failure rate of a braking air chamber is lowered.

Description

technical field [0001] The invention belongs to the technical field of truck braking systems, and relates to the technology of braking force output of the truck braking system. More specifically, the invention relates to a diaphragm spring brake air chamber of the truck braking system. Background technique [0002] In the prior art, the diaphragm spring brake air chamber of the truck brake system adopts a breathing pipe to lead to the public air filter of the driving cavity. Because there is no special filter medium for this structure, the poor working environment of the truck will cause the parking cavity to suck dust and fail to work for a long time. [0003] As shown in the accompanying drawings of this manual figure 1 As shown, the energy storage cylinder 4 is provided with a threaded bush 1 , and the adjusting bolt is installed in the energy storage cylinder 4 through the threaded bush 1 . A dust cover assembly 7 is provided on the push rod. In the figure, when the a...
