Abstract

The invention discloses a matching valve of a heavy truck braking system. The matching valve comprises an upper shell assembly (1) and a lower shell (7), wherein an air inlet (14) is arranged on the upper shell assembly (1); air outlets (15,16) are arranged on the lower shell (7); the matching valve is provided with an exhaust cover assembly (9); an exhaust port (17) is arranged on the exhaust cover assembly (9); a piston assembly (5) and an exhaust valve core (18) are arranged in the matching valve; a return spring (3) is arranged between the upper shell assembly (1) and the piston assembly (5); and the exhaust valve core (18) is matched with a valve port which is arranged on the lower shell (7) and leads to the exhaust port (17). According to the technical scheme, a braking force of an automobile front axle is reduced during incomplete brake; the brake performance of the whole automobile is improved by adjusting the ratio of input pressure to output pressure when the speed is reduced to be low by braking; and the matching valve has the effect of braking a quick release valve of an air chamber.

Description

technical field [0001] The invention belongs to the technical field of the air pressure control system of the heavy truck, and relates to the technology of the air delivery device of the control system. More specifically, the invention relates to a matching valve of the brake system of the heavy truck. Background technique [0002] In the prior art, the brake performance of the matching valve of the heavy truck brake system is not high enough, and its structure is not reasonable and compact enough. Contents of the invention [0003] The problem to be solved by the present invention is to provide a heavy-duty truck braking system matching valve, the purpose of which is to improve the braking performance of the whole vehicle. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] The heavy-duty truck brake system matching valve provided by the present invention includes an upper housing assembly and a lower housing,...
