Bidirectional brake wheel cylinder assembly

Abstract

The invention discloses a bidirectional brake wheel cylinder assembly which comprises a cylinder body and a push rod, wherein a radial through hole is arranged in the cylinder body; left and right pistons are arranged in the radial through hole; a spring is connected between inner lateral surfaces of the left and right pistons; the outsides of the left and right pistons are respectively provided with concave cavities; dustproof covers with middle holes are respectively arranged on the cylinder body and at both ends of the radial through hole; the tail ends of the push rod are provided with ball joints; the ball joints are in running fit with the inner walls of the concave cavities and are limited by check rings; the front end of the push rod passes through the through holes in the middle of the dustproof covers and extends out; the cylinder body is provided with an oil nozzle communicated to the radial through hole; the cylinder body is provided with an opening and is in threaded connection with a bleed screw; and the end part of the bleed screw is provided with a bleed cap. The bidirectional brake wheel cylinder assembly has compact structure and light weight, occupies small space, has good sealing performance and is provided with the bidirectional brake pistons. The connection relation between the pistons and external braking parts is designed into the relation that the concave cavities are matched with the ball joints. The motion space of the external braking parts is greatly expanded. The bidirectional brake wheel cylinder assembly has high practical value.

Description

technical field [0001] The invention relates to the field of automobile brakes, in particular to a bidirectional brake wheel cylinder assembly. Background technique [0002] The brake wheel cylinder generally relies on compressed air or oil to enter the brake cylinder, and pushes a set of basic devices such as the piston to perform the braking function. It is a part of the automobile brake and is used to generate the force that hinders the movement or movement trend of the vehicle, that is, the braking force. . [0003] Most of the existing brake wheel cylinder structures are relatively complex, bulky, and take up a lot of space, which brings a lot of inconvenience to installation and maintenance; in addition, the internal piston sealing performance is not good, which greatly affects the work efficiency. Most of the installed brake parts are fixedly connected, so that the brake parts can only move in a straight line, which limits the action space of the brake parts. C...
