Description
Technical field
The utility model relates to a kind of clutch master cylinder.
Background technique
Traditional clutch master cylinder generally includes the cylinder body of an end opening, active chamber in the cylinder body; Be provided with piston in the active chamber; The corresponding cylinder body opening end of piston is provided with push rod, and cylinder body is provided with the oil inlet hole of oil outlet and conducting inlet connector and active chamber, yet its compensate opening normally is arranged on the neutral position of active chamber; There is following defective in this structure: oil-feed, exhaust, oil extraction time are longer; Thereby influenced disengaging performance, and leather cup can swipe inevitably in the course of the work, thereby the working life that causes clutch master cylinder with compensate opening.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide that a kind of disengaging performance is better, the clutch master cylinder of longer service life.
Be to realize above-mentioned purpose, the utility model provides following technological scheme: a kind of clutch master cylinder comprises the cylinder body of an end opening; Active chamber in the cylinder body; Be provided with piston in the active chamber, the corresponding cylinder body opening end of piston is provided with push rod, and cylinder body is provided with the oil inlet hole of oil outlet and conducting inlet connector and active chamber; Said oil inlet hole is arranged on the other end of opposed openings end in the valve pocket; The relative push rod the other end of piston is connected with connecting rod, and the relative piston the other end of connecting rod is provided with the centre valve assembly that matches with oil inlet hole, is folded with Returnning spring between centre valve assembly and the piston.
Through adopting technique scheme, shorten oil-feed, exhaust, oil extraction time, thereby improved disengaging performance, and, there is not the situation of leather cup scraping compensate opening, prolonged working life.
The utility model further is provided with: said centre valve assembly comprises spool; The spool outside is arranged with return spring holder; Said Returnning spring is folded between return spring holder and the piston; The corresponding oil inlet hole of spool position is provided with the Sealing that matches with oil inlet hole, and the spool middle part also is provided with annular boss, also is folded with pressure spring between relative oil inlet hole opposite side of annular boss and the return spring holder.
The utility model further is provided with: the opening end of said cylinder body also is provided with dust-proof cover, also is provided with the stopping back-up ring between the opening end of cylinder body and the push rod.
Below in conjunction with accompanying drawing the utility model is further described.
