Brake wheel cylinder

Abstract

The invention relates to a brake wheel cylinder. The brake wheel cylinder comprises a cylinder body, a spring, a right brake mechanism, a right brake push rod, a right guide sleeve, a right end cover, a left brake mechanism, a left end cover, a left guide sleeve and a left brake push rod, wherein an axial through hole is formed in the cylinder body, an oil inlet hole is formed in the middle of the upper end of the cylinder body, an oil nozzle is installed at the upper end of the oil inlet hole, the right brake mechanism and the left brake mechanism are installed at two ends of the axial through hole respectively, and the spring is arranged between the right brake mechanism and the left brake mechanism. The brake wheel cylinder has the advantages that the structural design is reasonable, production costs are low, the brake push rods are separated from pistons so that production machining difficulty is reduced, mounting and using are convenient, adjustment and replacement are easy, balls are matched with spherical grooves to form sphere pairs, stability and flexibility of movement of the brake push rods are improved, the guide sleeves are matched with the brake push rods, movement accuracy is guaranteed, meanwhile, abrasion is reduced, and production costs are saved.

Description

technical field [0001] The invention relates to an automobile brake system, in particular to a 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 structure of the brake push rod of the traditional brake wheel cylinder and the piston is integrated, because the movement track of the piston is a reciprocating straight line during the braking process, so that the brake push rod of the brake cylinder during the braking process of the car The motion is also a reciprocating linear motion, which increases the friction between the push rod and the car brake shoe swing rod, which intensifies the wear between the two, shortens the service ...

AI Technical Summary

Problems solved by technology

The structure of the brake push rod of the traditional brake wheel cylinder and the piston is integrated, because the movement track of the piston is a reciprocating straight line during the braking process, so that the brake push rod of the brake cylinder during the braking process of the car The motion is also a reciprocating linear motion, which increases the friction between the push rod and the car brake shoe swing rod, which intensifies the wear between the two, shortens the service life of the brake wheel cylinder, and even causes the brake failure of the car. A traffic accident occurs with unimaginable consequences

There are various brake wheel cylinders on the market at present, but none of them solves the problem of large mechanical wear between the brake push rod and the automobile brake shoe swing rod, or uses lubricating oil to reduce the wear. But this not only increases the cost of the car owner, but also does not fundamentally solve the problem, and there are potential safety hazards, so a kind of brake wheel cylinder is urgently needed to solve the above-mentioned problems
