Abstract
The utility model discloses a clutch master cylinder with an oil return piece. The clutch master cylinder comprises a cylinder body, a working cavity is formed in the cylinder body, the right end of the working cavity is opened an oil outlet is formed in the left end, a piston is installed in the working cavity in a sliding mode, a spring seat is arranged at the left end of the piston, a spring is arranged on the spring seat, the left end of the spring abuts against the opening portion of the oil outlet, a push rod hole seat is arranged at the right end of the piston, a connecting rod is connected between a piston assembly and the push rod hole seat, a seal ring is arranged on the side wall of the piston, the oil return piece is fixedly installed on the end face of the piston, a secondary leather cup is arranged on the side wall of the push rod hole seat, an oil inlet joint is arranged on the side wall of the cylinder body, and an oil filtering piece is installed in the oil inlet joint. The clutch master cylinder is simple and compact in structure and small in size, and reduces machining difficulty of the body of the clutch master cylinder.
Description
Technical field
The utility model relates to a kind of clutch master cylinder that has the oil return sheet.
Background technique
What clutch used in the present automobile operation mechanism all is conventional clutch slave cylinder, piston in its structure only arranges seal ring between inner walls, oil leakage phenomenon appears in the course of the work easily, in addition, in the linkage structure of existing piston and push rod, behind the gap that the clutch plate wearing and tearing are produced, can not replenish automatically, the shortcoming of this system is complex structure, wheel cylinder center and separator levers are difficult to guarantee concentricity, produce noise and impact, make wheel cylinder produce eccentric wear easily, thereby influence the working life of wheel cylinder.
The model utility content
The utility model provides a kind of problem at leakage of oil in the above-mentioned clutch slave cylinder working procedure, provide simple in structure, compact, volume is little, can effectively prevent into the clutch slave cylinder assembly of ash and leakage of oil.
The utility model technical solution problem provides following scheme:
A kind of clutch master cylinder that has the oil return sheet, comprise cylinder body, the inside of described cylinder body is provided with active chamber, the right-end openings of described active chamber, left end is provided with oil outlet, be slidingly fitted with piston in the described active chamber, the left end of described piston is provided with spring seat, described spring seat is provided with spring, the left end of described spring withstands on the oil outlet oral area, it is characterized in that: the right-hand member of described piston is provided with the push-rod hole seat, is connected with connecting rod between described piston assembly and the push-rod hole seat, and the sidewall of described piston is provided with seal ring, be installed with the oil return sheet on the described piston end face, the sidewall of described push-rod hole seat is provided with secontary cup, and the sidewall of described cylinder body is provided with fuel inlet fitting, and the oil strain sheet is installed in the described fuel inlet fitting.
Oil outlet on the left end sidewall of described cylinder body connects oil nozzle.
The utility model working principle: the utility model is installed the oil return sheet at the sidewall of piston assembly, and filter sheet is installed in fuel inlet fitting, play the effect that purifies hydraulic oil, when the oil inlet hole oil-feed, leather cup on the piston is further opened, pressure is more high, sealing effect is more good, termination at cylinder body is provided with dust-proof cover, can effectively prevent dust, make to produce pressure in the cylinder body active chamber, it is outwards mobile to promote piston and push rod, promotes disengaging yoke by push rod again, release bearing, separate platen, thereby the effect that the power that reaches the cut-out motor transmits to speed changer, the spring in the described active chamber plays buffer function when pistons work, reduce noise and impact.
Description of drawings
Fig. 1 is structural representation of the present utility model.
