Abstract
The invention discloses a clutch branch pump suitable for a manual transmission automobile. The clutch branch comprises a clutch branch pump body and a dustproof cover, wherein the clutch branch pump body consists of a cylinder body, a piston, a piston push rod, a pressure spring, an exhaust screw and a dustproof plug; the piston, the piston push rod and the pressure spring are arranged in the cylinder body, and the exhaust screw and the dustproof plug are arranged on the wall of the cylinder body; the dustproof cover is arranged at the cylinder port of the cylinder body in a sealing mode; the piston push rod extends out of the dustproof cover in a sliding and sealing mode; a calibrated scale is arranged on the outer surface of the piston push rod along the axial direction; an annular groove is formed in the peripheral surface of the cylinder port in a surrounding mode, and the cross section of the annular groove is of a hook-shaped structure; an inner flanging is arranged on the cover port of the dustproof cover, and the cross section of the inner flanging is of a hook-shaped structure suitable for the shape of the cross section of the annular groove; the inner flanging of the cover port is engaged with the annular groove of the cylinder port. The clutch branch pump has the advantages that the wear condition of a friction plate of a clutch driven plate is accurately and quickly judged in time, serious potential safety hazards caused by the fact that the friction plate of the clutch driven plate is not changed in time are effectively avoided, and the occurrence that the dustproof cover is easily separated from the cylinder body of the clutch branch pump is completely eradicated.
Description
Technical field
The present invention relates to manual-gear vehicle hydraulic type clutch control system, especially relate to the clutch slave cylinder that is suitable for manual-gear vehicle.
Background technique
At present, manual-gear vehicle all adopts hydraulic type clutch control system, and it is mainly comprised of diaphragm spring clutch, clutch general pump, clutch slave cylinder, clutch oil pipe, clutch flexible pipe and clutch pedal etc.The hydraulic oil of on-off control mechanism is from the clutch liquid in clutch general pump lubricating cup.In vehicle using process, the friction plate of clutch driven plate can wear and tear, before may wear to limit case, and the clutch driven plate that just must more renew, otherwise can damage engine flywheel and clutch compressing disc.But, the inspection of clutch driven plate friction plate abrasion degree need to be opened clutch and be carried out, this is just in time judged whether friction plate has reached wear limit and brought difficulty, therefore has the potential safety hazard of damaging clutch compressing disc or flywheel due to the driven disc more not renewing in time.Meanwhile, the dust-proof cover of existing clutch slave cylinder and the linkage structure of the pump housing are clamping, and dust-proof cover is stuck in the draw-in groove at pump housing assembling position by the in-flanges of its cover mouth; Therefore, clutch slave cylinder is being installed and is being transported in handling process, and dust-proof cover and the pump housing easily depart from, and causes operator to repeat to install; And when dust-proof cover is under temperature distortion state, the easy and pump housing departs from, and causes foreign matter to enter in clutch slave cylinder cylinder body, cause the wearing and tearing of cylinder interior textural anomaly and reduction of service life.
Summary of the invention
The object of the invention is to provide a kind of clutch slave cylinder that is suitable for manual-gear vehicle.
For achieving the above object, the present invention takes following technical proposals:
The clutch slave cylinder that is suitable for manual-gear vehicle of the present invention, comprise by cylinder body, be arranged on piston, piston push rod, the pressure spring in described cylinder body and be arranged on the exhaust bolt on cylinder wall, the clutch slave cylinder body that dust plug forms, and sealing the dust-proof cover that is arranged on described cylinder body cylinder mouth place, described piston push rod slipper seal is extended outside described dust-proof cover; Described piston push rod outer surface is axially provided with calibrated scale along it; Around described cylinder mouth outer circumferential face, offer the annular groove that transverse section is hook-shape structure, the cover mouth of described dust-proof cover is provided with in-flanges, and the transverse section of described in-flanges is the hook-shape structure adapting with described annular groove transverse shape; The in-flanges of described cover mouth and the annular groove phase interlock of described cylinder mouth.
The invention has the advantages that realization judges the state of wear of clutch driven plate friction plate promptly and accurately, fast, effectively avoid more not renewing in time the serious potential safety hazard that clutch driven plate friction plate brings; Stop the generation of described dust-proof cover and the easy break-off of clutch slave cylinder cylinder body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the I portion structure for amplifying schematic diagram of Fig. 1.
Embodiment
As shown in Figure 1, the clutch slave cylinder that is suitable for manual-gear vehicle of the present invention, comprise by cylinder body 1, be arranged on piston 2, piston push rod 3, the pressure spring 4 in described cylinder body 1 and be arranged on the exhaust bolt 5 on cylinder wall, the clutch slave cylinder body that dust plug 6 forms, and sealing the dust-proof cover 8 that is arranged on described cylinder body cylinder mouth 7 places, described piston push rod 3 slipper seals are extended outside described dust-proof cover 8; Described piston push rod 3 outer surfaces are axially provided with calibrated scale 9 along it.As shown in Figure 2, around described cylinder mouth 7 outer circumferential faces, offer the annular groove 10 that transverse section is hook-shape structure, the cover mouth of described dust-proof cover 8 is provided with in-flanges 11, and the transverse section of described in-flanges 11 is the hook-shape structure adapting with described annular groove 10 transverse shapes; Described dust-proof cover 8 in-flangess 11 of cover mouth and the annular groove 10 phase interlocks of described cylinder mouth 7.
Working principle of the present invention is summarized as follows:
As shown in Figure 1, the present invention is in vehicle using process, wearing and tearing along with clutch driven plate friction plate, clutch cover and plate assembly diaphragm separation finger will move to gearbox direction (car load+directions X), thereby drive release bearing to move to gearbox, simultaneously, the piston push rod 3 that disengaging yoke promotes clutch slave cylinder moves to car load-directions X, be that the positive size numerical value of exposing of clutch slave cylinder piston push rod 3 high scale chis 9 is increasing, therefore, the degree of wear of clutch driven plate friction plate is just reflected at a glance by the displacement scale on clutch slave cylinder piston push rod 3.When the displacement scale of piston push rod 3 reaches capacity sizing, can judge that clutch driven plate friction plate has arrived wear limit, the clutch driven plate that need to more renew, this determination methods is simple, accurate, quick, has effectively avoided more not renewing in time the serious potential safety hazard that clutch driven plate friction plate brings.In addition, by the calibrated scale 9 on piston push rod 3, also can obtain fast the real work stroke of clutch slave cylinder on real vehicle, solve the problem of existing actual measurement clutch slave cylinder stroke inconvenience.As shown in Figure 2, the cylinder mouth 7 of cylinder body 1 is hook-type annular groove 10 structures with the cover mouth joint of dust-proof cover 8, after both assemblings, interlock is tight, be difficult for departing from, not only solved existing clutch slave cylinder install and transportation handling process in dust-proof cover 8 easily depart from, cause operator to repeat the problem of installing with cylinder body 1, solved again clutch slave cylinder dust-proof cover 8 and easily caused foreign matter to enter in cylinder body 1 with cylinder body 1 disengaging under temperature distortion state, and caused the problem of cylinder body 1 internal structure inordinate wear.
