Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the current clutch master cylinder that the pressure of the liquid outlet hole is not easy to build up and the speed of hydraulic oil backfilling the liquid supply chamber is relatively slow, and provide a method that is easy to build up the pressure of the liquid outlet hole and the backfill pressure of the hydraulic oil. Faster clutch master cylinder

Abstract

The invention relates to the field of automobile clutches and aims to provides a clutch master cylinder which comprises a pump body, a piston, a reset spring and a push rod, wherein the reset spring is used for resetting the piston; the front end of the push rod stretches into the pump body, so as to push the piston; a pressure cavity is formed by the front end of the piston and the pump body; an annular groove is formed in a side wall of the piston; a liquid feeding cavity is formed between the annular groove and a side wall of the pump body; a liquid inlet hole communicated with the liquid feeding cavity and a liquid outlet hole communicated with the pressure cavity are formed in the pump body; a liquid passing through hole communicated with the liquid inlet hole is formed in one end of the pump body; if a clutch pedal is not trampled, the piston is in an initial position; the other end of the liquid passing through hole is communicated with the pressure cavity. When the clutch master cylinder works, the pressure of the liquid outlet hole is easy to establish, and the pressure cavity is backfilled with hydraulic oil faster.

Description

technical field [0001] The invention relates to the field of automobile clutches, in particular to a clutch master cylinder. Background technique [0002] The clutch master cylinder is a part connected to the clutch pedal and connected to the clutch booster through the oil pipe. Its function is to collect pedal stroke information and realize the separation of the clutch through the action of the booster. The invention of Chinese Patent Publication No. CN102367844A discloses an automobile clutch master cylinder assembly, including a cylinder body, a piston is slidably installed in the cylinder body, a spring seat is fixed at the rear end of the piston, and a cushion is placed between the spring seat and the cylinder body. Spring, the front end of the piston is connected with a push rod, the end of the spring seat is covered with a dust cover, the front end of the push rod is screwed with a nut, the side wall of the cylinder body is inserted with an oil inlet joint, and an oil...
