Abstract

The invention relates to an 8-inch vacuum booster assembly with a floating diaphragm structure, belonging to the technical field of automobile braking systems. The front housing part is riveted to therear housing part. A diaphragm is arranged between the front housing part and the rear housing part. The rear housing gas seal is interference-fitted with the rear housing part to form a sealed shell, and the rear housing gas seal is interference-fitted with the valve body. The booster disk is riveted with the valve body, and the control valve part and the valve body are clamped and assembled through a locking plate. The feedback disk, the retainer ring, and the master cylinder push rod are assembled in the valve body, and the return spring is assembled on the retainer ring, and the dust cover is assembled on the rear housing part. The 8-inch vacuum booster assembly with a floating diaphragm structure has the advantages of novel structure, improved product reliability, good positioning, simple assembly, small occupying space and easy processing.

Description

technical field [0001] The invention belongs to the technical field of automobile brake systems, in particular to a vacuum booster assembly. Background technique [0002] The existing conventional vacuum booster assembly used for automobile braking consists of: front housing, rear housing, rear housing bolts, rear housing air seal, control valve parts, lock plate, dust cover, adjustment fork, pressure block, Feedback plate, master cylinder push rod, retainer, return spring, valve body, diaphragm, booster plate and other main components. [0003] During the operation of the conventional vacuum booster assembly, the input force from the brake pedal drives the control valve part to cooperate with the valve body, and the vacuum booster assembly is divided into two chambers, the front chamber is the vacuum chamber, and the rear chamber is connected to the atmosphere through the diaphragm. , which is affected by atmospheric pressure to produce a boosting effect. [0004] However...
