Embodiment Construction
[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0016] Compared with the existing installation method of the output force push rod, the present invention provides an installation method that is simple, less time-consuming, less prone to errors, improves production efficiency, and reduces labor intensity. Therefore, the output in the embodiment of the invention The push rod end 21 and the mating plug-in parts on the end installation base 22 are inserted into each other, and when the length of the output force push rod is just a predetermined value, the mating plug-in parts are radially compressed to generate Plastic deformation, so that t...

The invention provides a method for mounting the end of an output force pushing bar of a vacuum booster and an actuating mechanism thereof. The output force pushing bar comprises a pushing bar end and an end mounting base, the end mounting base is fixed in a sub-assembly of the vacuum booster, and the pushing bar end and the end mounting base have mutually matched plugging parts. The method comprises the following steps of plugging the mutually matched plugging parts, radially compressing the plugging parts to enable the plugging parts to generate plastic deformation when the length of the output force pushing bar is just a preset value, so that the output force pushing bar end and the output force pushing bar are integrated. The actuating mechanism comprises an output force pushing bar end mounting mechanism, a positioning member, a riveting mechanism and a feeding mechanism. In the invention, the output force pushing bar has simple mounting way, takes a short time, is not easy to have a fault, improves the labor intensity, can also guarantee the consistency of part machining and is more suitable for the modern line production.
Description
technical field [0001] The invention relates to a method for installing an output push rod of a vacuum booster and an actuator of the method. The vacuum booster belongs to a part of a brake system, and the method is especially applicable to automobiles. Background technique [0002] The brake device system includes a master cylinder and a vacuum booster, wherein the vacuum booster includes an output force push rod, and the vacuum booster is connected with the piston of the master cylinder through the output force push rod. In the case of a car, the brake pedal acts on the pushrod, which pushes the master cylinder piston so that the piston moves in a chamber of the master cylinder and increases the pressure on the output side of the master cylinder. [0003] In such a master cylinder and vacuum booster system, there is a controlled idle travel in order for the brake pedal to act as quickly as possible on the corresponding master cylinder piston. Typically, the length of the ...
