Automobile hydraulic cylinder setter

Abstract

The invention relates to the comprehensive development and application of automobile maintenance engineering, belonging to the mechanical engineering of automobile maintenance. According to the basic principle of parallelogram and trapezoidal thread driving torque, one of two equal modules is used as a positioning block, and a positioning round bar and a module hole form a force point through close fit; and a module hole of the other module is in loose fit transmission with the round bar, the module is pulled by a trapezoidal thread, and the torque is transferred up and down by the positioning round bar. In practical use, the setter is arranged on the inner side of a braking cylinder bracket, and the trapezoidal thread rotates clockwise so that the module expands outwards to compact a piston for resetting. To take out the cylinder piston, a dustproof sleeve groove of the cylinder piston is clamped by a movable fixture, a module connection hook is sleeved thereon, the setter is arranged on the outer side of the braking cylinder bracket, and the trapezoidal thread rotates anticlockwise to pull the piston out of the cylinder. Through the invention, time and labor are saved in operation by one person.

Description

technical field [0001] The invention relates to the comprehensive development and utilization of automobile maintenance engineering, which belongs to the mechanical engineering of automobile maintenance. Background technique [0002] Most of the existing automobiles are disc brake systems. If you use the brakes for a long time, decelerate, and switch between spring, summer, autumn and winter, the brake system will produce some dirty substances, which will affect the braking return. During maintenance and cleaning, it is mainly time-consuming and laborious to reset the sub-pump. Many maintenance units use manual and crowbars to hard press the sub-pump piston to reset it, which is very unsafe. Contents of the invention [0003] The purpose of the present invention is to reduce unnecessary losses, from the perspective of economy, practicality and durability, and according to the principle of automobile design structure, a hydraulic sub-cylinder setter is designed. It meets t...

[0002] Most of the existing cars are disc brake systems. If you use the brakes for a long time, decelerate, and switch between spring, summer, autumn and winter, the brake system will produce some dirty substances, which will affect the braking return.

During maintenance and cleaning, it is mainly time-consuming and laborious to reset the sub-pump. Many maintenance units use manual and crowbars to hard press the piston of the sub-pump to reset it, which is very unsafe.
