Clutching device

Abstract

The invention provides a clutching device. The clutching device comprises a cylinder body, a return spring, leather cups and a piston. The return spring is installed at the tail end of the piston, andthe return spring and the piston are installed in the cylinder body. The leather cups are installed at the two ends of the piston, and a guide sleeve is installed outside the piston and makes close contact with an inner cavity of the cylinder body. The clutching device is long in service life, excellent in performance, reliable in quality, simple in structure and convenient to install.

Description

technical field [0001] The invention relates to the field of clutch technology, in particular to a clutch device. Background technique [0002] The clutch device is used to compress the force and displacement of the automobile clutch pedal to establish a certain hydraulic output device through the compression of the hydraulic oil. After the hydraulic oil is discharged, the next action cycle must be prepared. When the piston retreats, the hydraulic oil needs to be replenished in front of the piston. When the piston is at the limit position, the pressure needs to be balanced. Therefore, a balance compensation mechanism is generally required in the clutch device to operate normally. The clutch device in the prior art includes a compensation hole type liquid replenishment structure, but the compensation hole is easily blocked, and there are many potential failure factors. For example, the patent "201220006022.5" discloses a clutch master cylinder with an accumulator, which inclu...

Problems solved by technology

[0003] In order to overcome the problems of low force transmission efficiency and pressure building failure in the prior art, the present invention provides a clutch device, including a cylinder, a return spring, a leather cup, and a piston, wherein the return spring is installed at the end of the piston , the return spring and the piston are installed in the cylinder, and the two ends of the piston are equipped with leather cups. It is polytetrafluoroethylene. The two ends of the piston in contact with the guide sleeve have at least one annular gap. The piston divides the space in the cylinder into a pressure chamber and a liquid supply chamber. The left end of the pressure chamber is larger than the right end. The diameter of the cavity is small, the cylinder body includes an oil inlet hole and an oil outlet hole, and the oil inlet hole of the cylinder body includes an oil inlet pipe joint
