AI Technical Summary

Problems solved by technology

The brake push rod and the piston of the traditional brake wheel cylinder have an integrated structure. If the piston is damaged, the two must be replaced together. This not only makes maintenance difficult, but also increases maintenance costs and wastes resources.
In addition, when the piston slides in the piston hole, it will often deviate over time, that is, the axis of the piston and the axis of the piston hole are not on the same straight line, which will often cause the piston to be stuck. Stuck will cause the brake system to fail, the consequences will be disastrous

Abstract

The invention relates to a combined brake wheel cylinder. The combined brake wheel cylinder comprises a cylinder body, an axial through hole is formed in the cylinder body, a right piston and a left piston are mounted at two ends of the axial through hole of the cylinder body respectively, a semi-spherical groove is formed in one end of the right piston, a conical boss is arranged at the other end of the right piston, a guide column is mounted on the surface of the conical boss, a guide hole is formed in one end of the left piston, the guide column is inserted into the guide hole, a semi-spherical groove is formed in the other end of the left piston, a spring is installed between the right piston and the left piston, the spring sleeves the conical boss, leather rings are disposed in middles of the right piston and the left piston, leather bowls are mounted at left and right ends of the cylinder body, brake push rods are arranged at one end of the right piston and one end of the left piston, and dust-proof covers are installed at two ends of the cylinder body. According to the combined brake wheel cylinder, the brake push rods are hinged to the pistons through sphere pairs, the movement flexibility of the brake push rods is improved, the guide column is matched with the guide hole, and thereby, the accuracy during movement of the pistons can be guaranteed.

Description

technical field [0001] The invention relates to an automobile brake system, in particular to a combined brake wheel cylinder. Background technique [0002] As we all know, the automobile brake wheel cylinder is installed in the automobile wheel disc, which is used for automobile braking and is an important device to ensure the safety of automobile braking. Common hydraulic brake wheel cylinders are usually used in general automobiles, generally including cylinder body , Piston, spring nozzle, etc. The brake push rod and the piston of the traditional brake wheel cylinder have an integrated structure. If the piston is damaged, the two must be replaced together. This not only makes maintenance difficult, but also increases maintenance costs and wastes resources. In addition, when the piston slides in the piston hole, it will often deviate over time, that is, the axis of the piston and the axis of the piston hole are not on the same straight line, which will often cause the pis...
