Abstract
The invention discloses a high sealing clutch master cylinder, which comprises a cylinder body. A piston is arranged in the cavity of the cylinder body in a sliding way, the rear end of the piston is sleeved in a dustproof cover, the dustproof cover is wavy, the front end of the piston is provided with a valve seat, a valve shell is arranged in the valve seat and is filled with a valve apron, a spring is cushioned between the piston and the cylinder body, the front end of the cylinder body is provided with an oil nozzle, and the oil nozzle is provided with a dustproof plug. The functions of a clutch are realized via the sliding piston. Meanwhile, the sealing valve seat is arranged in the piston, the structural design is reasonable, the improvement of the sealing performance of the clutch can be facilitated, and the braking force of the automotive clutch can be improved.
Description
Technical field
The present invention relates to clutch field, specifically belong to the high sealing clutch master cylinder.
Background technique
Clutch master cylinder, wheel cylinder are equivalent to two oil hydraulic cylinders, and the turnover oil pipe is arranged on the master cylinder, and wheel cylinder has only a pipe.Step on clutch, the pressure transmission of master cylinder is divided pump work to wheel cylinder, and disengaging yoke breaks away from flywheel with clutch compressing disc and sheet, at this moment just can begin gear shift.Loosen the clutch, wheel cylinder quits work, and clutch compressing disc and sheet contact with flywheel, and power transmission continues, the oil backflow oil-feed kettle of wheel cylinder.When the gear shift difficulty, when separation is thorough, need to detect clutch master cylinder, wheel cylinder has or not oil seepage phenomena, has problem in time to solve, and reduces to wear and tear.Other do corresponding inspection.
Summary of the invention
The purpose of this invention is to provide a kind of high sealing clutch master cylinder, reasonable in design helps improving the sealability of clutch, has improved the braking force of automobile clutch.
Technological scheme of the present invention is following:
The high sealing clutch master cylinder includes cylinder body, and inner chamber of cylinder block is slidingly fitted with piston; The rear end of piston is set with dust-proof cover, and it is wavy that dust-proof cover is, and the front end of piston is equipped with valve seat; Be provided with valve casing in the valve seat, be filled with the valve leather circle in the valve casing, be equipped with spring between piston and the cylinder body; The front end of cylinder body is equipped with oil nozzle, and dust plug is installed on the oil nozzle.
The rear end of described piston is provided with the hole and uses back-up ring.
The present invention adopts the piston of slip to realize the function to clutch, is provided with seal valve seat in the piston simultaneously, and reasonable in design helps improving the sealability of clutch, has improved the braking force of automobile clutch.
Description of drawings
Fig. 1 is a structural representation of the present invention.
