AI Technical Summary

Technical Problem

Existing brake cylinders suffer from problems such as short disc spring life and easy breakage, large mechanical wear, high noise, and inability to infinitely change braking force.

Method used

It adopts a bladder accumulator and hydraulic system, and uses high-pressure gas instead of disc springs. By changing the inflation pressure and oil pressure, it can achieve automatic compensation and stepless change of braking force, reduce mechanical wear and reduce noise.

Benefits of technology

It extends the service life of the brake cylinder, reduces mechanical wear and noise, and has an automatic braking force compensation function, which can steplessly change the braking force.

Abstract

The application belongs to the technical field of brake manufacturing, and relates to a brake cylinder and a control method thereof. The brake cylinder comprises a cylinder, a front cover, a rear cover, a piston and a screw rod. The front cover and the rear cover are respectively sealed and connected to the front end and the rear end of the cylinder. The piston is arranged in the cylinder and divides the inner cavity of the cylinder into a working chamber and an energy storage chamber. The front end of the piston is integrally provided with a piston rod. The diameter of the piston rod is smaller than that of the piston. The piston rod is in sealed sliding connection with the front cover. The end of the piston rod away from the piston is fixedly connected with the screw rod. The brake cylinder further comprises a bag-type energy accumulator. The control method of the brake cylinder is to change the inflation pressure of the energy accumulator and set a certain working oil pressure under the condition that the design parameters of the brake cylinder are constant, so that the required braking force of the brake can be obtained. The device has a long service life, small mechanical wear, low noise, an automatic braking force compensation function and can infinitely change the braking force of the brake cylinder.
