Brief description of the drawings
Fig. 1 is the profile of the clutch slave cylinder of the specific embodiment of the invention；
Fig. 2 is the exploded view of the clutch slave cylinder of the specific embodiment of the invention.
Embodiment
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
Clutch release system includes clutch slave cylinder.Referring to Figures 1 and 2, clutch slave cylinder 1 includes：Cylinder body 2,
Piston 3 and the stop part 4 on cylinder body 2.Cylinder body 2 is provided with annular pressure chamber 2a, pressure chamber 2a and surround the axis of cylinder body 2,
Piston 3 is used for reciprocating in the axial direction of pressure chamber 2a interior edges cylinder body 2；Stop part 4 is located at piston 3 and is axially distant from pressure chamber
Side in 2a, come off for stopping piston 3 from cylinder body 2.When oil-filled in pressure chamber 2a, piston 3 moves to stop part 4,
Stop part 4 can stop that piston 3 is scurried out from cylinder body 2 vertically.
Wherein, stop part 4 is arranged on the outer peripheral face 20 of cylinder body 2.This can bring following advantage：
The inner peripheral surface 21 of stop part 4 and cylinder body 2 is without common factor, it is not necessary to inner peripheral surface 21 is improved, after mould molding,
The knockout course of cylinder body 2 from inner peripheral surface 21 is readily achieved, simple for manufacturing the mold design of cylinder body 2 of clutch slave cylinder 1,
It is easily achieved, manufacturing cost reduces.Moreover, the space outside cylinder body 2 is larger.This can give the outer peripheral face 20 of stop part 4 and cylinder body 2
Assembling process provides larger operating space, lifting assembling convenience, reduces installation cost.
The inner peripheral surface 30 that is radially outward higher by piston 3 of the stop part 4 along cylinder body 2.When piston 3 keeps out stop part 4, piston
3 corresponding end-faces have sufficient backstop area vertically with stop part 4, and this can more effectively lift the backstop effect of stop part 4
Fruit, prevent piston 3 is scurried out from coming off.
Clutch slave cylinder 1 can be clutch alignment formula pair cylinder, and pipe is externally provided with the one end of cylinder body 2 away from stop part 4
Body 10, the outer peripheral face 20 of body 10 and cylinder body 2 define pressure chamber 2a.Release bearing 5 is coaxially provided with outside cylinder body 2, is separated
Bearing 5 is axially offseted with piston 3 vertically, and release bearing 5 can be axially moved with respect to the cylinder body 2 of clutch slave cylinder 1.Separation shaft
5 are held by the pressure towards piston 3, can be axially moved with piston 3 into pressure chamber 2a, pressure chamber 2a internal drainages；Toward pressure
Oil-filled in chamber 2a, piston 3 is promoted the counter motion of release bearing 5 by hydraulic pressure.
Preloading spring 6 is arranged with outside clutch slave cylinder 1, the one end of preloading spring 6 is against clutch slave cylinder 1, and separately
One end is against release bearing 5, and axial pretightening is carried out to release bearing 5.Seal closure 7, seal closure 7 are covered with outside preloading spring 6
Release bearing 5 and clutch slave cylinder 1 are axially fixed to, seal closure 7 plays sealing function to clutch slave cylinder 1, isolation
External dust and water pollution.When release bearing 5 compresses preloading spring 6 and moved, seal closure 7 is deformed and elastic deformation.
Cylinder body 2 outer peripheral face 20 formed with holding tank 23, stop part 4 is limited in holding tank 23 and along the footpath of cylinder body 2
To protruding from outside holding tank 23.In assembling, stop part 4 is loaded in holding tank 23, easy to operate, lifting assembling effect
Rate.
Holding tank 23 has two side walls 230 that are axially opposing along cylinder body 2 and setting, and stop part 4 can be clamped on two sides
Between wall 230, stop part 4 is limited vertically.
Holding tank 23 can be manufactured by mould molding.Compared to prior art press fitting groove is formed in the inner peripheral surface of cylinder body
Mould, holding tank 23 is formed in the outer peripheral face 20 of cylinder body 2, after shaping, cylinder body 2 is easily achieved from the demoulding of outer peripheral face 20 so that into
Type mold design is simple.
Axial direction of the internal diameter of cylinder body 2 along cylinder body 2 can have uniformity, the inner peripheral surface 21 of cylinder body 2 do not formed projection or
Groove, cylinder body 2 are also easy to realize from the demoulding of inner peripheral surface 21.
Stop part 4 in a ring, surround cylinder body 2.The stop part 4 of annular can have greater overlap area vertically with piston 3
Domain, it can more effectively stop that piston 3 is leapt up out from cylinder body 2.
For convenience of installation, annular stop part 4 circumferentially has breach 40.In assembling, breach 40 can be opened, by only
Block piece 4 is enclosed on cylinder body 2, and is moved in holding tank 23, and breach 40 shrinks afterwards, and stop part 4 is limited in holding tank 23.
Breach 40 can be manufactured on the stop part 4 of a closed ring.Or stop part 4 can directly utilize c-type
Ring.
As an improvement scheme, stop part can not have breach, when mounted vertically be pressed stop part strength
On cylinder body.In this case, the outer peripheral face of cylinder body can be not provided with holding tank.
In the prior art, in order to facilitate punching press to baffle ring, the thickness design of baffle ring is relatively thin, causes baffle ring can not
Axially larger pressure is born, causes piston that there is the risk for washing baffle ring and play disengaging cylinder body open.And in the technical program,
Punching operation need not be carried out to stop part 4.It is contemplated that the axial width of stop part 4 can design it is thicker, it is sufficient to bear
Piston 3 axially larger impulse force without deforming easily, stop part 4 can for a long time, effectively play backstop action.
Cylinder body 2 includes：The Part I 24 and Part II 25 axially connected；Part II 25 is more remote than Part I 24
Pressure chamber 2a, the external diameter of Part II 25 are less than the external diameter of Part I 24, and holding tank 23 is formed at the periphery of Part II 25
Face.The external diameter of Part II 25 is smaller, and the breach 40 of such stop part 4 need not open large-size, be advantageous to assemble.
Holding tank 23 ends to Part I 24 along the axial direction of cylinder body 2.So, in assembling process, Part I 24 rises
To the effect of assembling positioning, when stop part 4 is axially moved to Part I 24, that is, assemble in place.After mounting, stop part 4
Axially abutted with Part I 24, it is compact-sized.
Stop part 4 is plane along the two axial end surfaces 41 of cylinder body 2.Wherein, it is towards the surface 41 of the side of piston 3
Plane, this can provide stop part 4 and the contact area of piston 3, strengthen backstop effect.Therefore, stop part 4 can be at least along cylinder body
2 surface for being axially facing piston 3 is plane.
As a kind of variation, stop part can have it is multiple, all stop parts are circumferentially arranged along cylinder body.Now, cylinder
The outer peripheral face of body is correspondingly provided with multiple holding tanks, and stop part can be limited in corresponding holding tank.
Although present disclosure is as above, the present invention is not limited to this.Any those skilled in the art, this is not being departed from
In the spirit and scope of invention, it can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
The scope of restriction is defined.
