Abstract
The invention discloses a plunger type plastic clutch working cylinder which comprises a limit base, a U-shaped retainer, a spring holder and a spring. A center hole of a cylinder body is of a step-hole structure divided into an outer hole in the big end and an inner hole in the small end. The limit base which is of an annular structure is mounted between the outer hole and a plunger; the plunger is inserted in a center hole of the limit base and is limited by an internal flange arranged at the outer end of the limit base. A packing cup is mounted between the inner end of the limit base and the step of the inner hole of the cylinder body. A spherical groove matched with a pusher is formed in the center of the outer end of the plunger, a blind hole is formed in the center of the inner end of the plunger, and the spring holder is mounted in the blind hole. One end of the spring sleeves the spring holder while the other end of the spring is abutted against the bottom of the cylinder body. During separation of a clutch, the plunger is driven hydraulically to move between the center hole of the limit base and the inner hole of the cylinder body, with the packing cup fixed. The plunger type plastic working cylinder has stable structure, and allowable working pivot angle thereof is increased, so that oil leakage is avoided, quality of products is improved and failure rate after sale is reduced.

Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 1, clutch clutch release slave cylinder of the present invention comprises push rod 1, guard shield 2, piston 4, leather cup 6 and cylinder body 9, it is characterized in that: also comprise position limit socket 3, U-shaped back-up ring 5, spring seat 7 and spring 8, the center hole of described cylinder body 9 is shoulder hole structure, be divided into the large exit orifice of end and the endoporus of small end, the position limit socket 3 of loop configuration is installed between exit orifice and piston 4, move on the center hole of position limit socket 3 and the endoporus of cylinder body 9 in the center hole that piston 4 is sleeved on position limit socket 3, position limit socket 3 outer end is provided with the inward flange for piston limit, between position limit socket 3 the inner and the endoporus step of cylinder body 9, leather cup 6 is installed, leather cup 6 end face leans against on cylinder body step, back leans against on position limit socket.
As shown in Figure 4, center, piston 4 outer end has the ball recess coordinated with push rod 1, push rod 1 end face withstands on ball recess place, the inner center of piston 4 has blind hole, be provided with spring seat 7 in blind hole, spring 8 one end is enclosed within spring seat 7, as shown in Figure 5, spring seat is that spring play the guiding role, and spring 8 the other end withstands on bottom cylinder body 9; When clutch separation, hydraulic drive piston movement, piston 4 moves between the center hole and the endoporus of cylinder body 9 of position limit socket 3, and leather cup does not move.
The internal diameter of above-mentioned position limit socket 3 center hole is identical with the internal diameter of cylinder body 9 endoporus.
As shown in Figure 2, position limit socket 3 outer side surface has annular groove circumferentially, and U-shaped back-up ring 5 opening end is stuck on the annular groove of position limit socket 3, and U-shaped back-up ring 5 intermediate section to be stuck in outside cylinder body 9 in groove, position limit socket 3 as shown in Figure 3, thus is fixed on cylinder body 9 by U-shaped back-up ring 5.
Therefore, when piston 4 moves, between leather cup stationary housing of the present invention and position limit socket, position limit socket 3 and leather cup 6 all keep fixing, and leather cup is not along with piston moves together.Internal piston is emptied, spring is contained in internal piston, led by spring seat, be fixed on piston assembly inside, spring can not produce scraping to cylinder body when moving bending, make clutch clutch release slave cylinder structural stability by leather cup and spring improved structure thus, increase permission work pivot angle, avoid leakage of oil.
Specific embodiment of the invention working procedure is as follows:
As shown in Figure 2, the outer end of position limit socket has groove, is fixed on cylinder body by U-shaped back-up ring (see figure 3).Position limit socket internal diameter is identical with the cylinder diameter of the small end endoporus of cylinder body, and in close cylinder body oral area one end, position limit socket has projection, and bump openings size is less than piston external diameter, plays piston limit effect.
As described in Figure 4, piston external diameter is identical with cylinder diameter, is Spielpassung.Piston left end has a ball recess, coordinates with push rod.Empty in the middle of piston right-hand member, there is a spring seat (see figure 5) inside, for spring play the guiding role.With internal piston consistent size bottom piston seat, avoid producing play.Spring one end is enclosed within spring seat, and the other end withstands on cylinder base.When piston movement, spring is also tight, bending at internal piston, can not produce scraping to inboard wall of cylinder block.
Production is concrete implement in have employed the Novel work cylinder of this structure after, under the same work pivot angle, working life, more original structure was high by more than 30%, and the rate of breakdown after sale caused because of eccentric wear reduces more than 90%.Thus, (work pivot angle of the present invention can reach 5 degree to invention increases the work pivot angle of product, 3 degree can only be reached) in existing, greatly reduce rate of fault, avoid leakage of oil, avoid the eccentric wear scraping of spring, improve quality of product, improve structure, there is significant technique effect and significance.
Above-mentioned embodiment is used for explaining and the present invention is described, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment make the present invention and change, all fall into protection scope of the present invention.
