The bottom of the piston rod is sleeved with the piston valve, the bottom valve is arranged at the bottom of the working cylinder, the oil seal guide assembly is arranged on the top, corresponding to the working cylinder and the oil storage cylinder, of the piston rod, the top of the piston rod is matched and connected with an upper flying ring through threads, the top end of the piston rod is connected with a rubber bushing through the upper flying ring, the dust cover is arranged between the oil storage cylinder and the rubber bushing, one end of the dust cover stretches into and is clamped into the oil storage cylinder, and the other end of the dust cover abuts against and presses the rubber bushing. The structure and assembly of the dust cover are improved, the dust cover can wholly cover the part, outside the working cylinder, of the piston rod, and therefore the piston rod can be well protected; the dust cover can be well fixed through the upper flying ring and the rubber bushing, the dust cover cannot easily disengage, and therefore the good shock absorbing effect of the shock absorber can be kept.
Description
Technical field
The utility model relates to auto parts machinery field, is specifically related to a kind of cylindrical automobile shock absorber.
Background technique
In order to improve the stationarity of automobile running, make it more comfortable; in automotive suspension, conventionally vibration damper can be installed; its working principle is when being subject to vibrations to occur relative movement between vehicle frame and vehicle bridge; piston in vibration damper is up and down; fluid in vibration damper chamber just flows in another chamber from different spaces repeatedly in a chamber; now; the intermolecular interior friction of friction between hole wall and fluid and fluid forms damping force to vibrations; the heat energy that the Conversion of Energy that makes thump is fluid, then have vibration damper to absorb to be transformed in air and go.
Current vibration damper generally includes clutch release slave cylinder, oil storage cylinder, piston rod, piston valve, bottom valve, oil sealing guidance set, dust-proof cover, piston valve is sheathed on the bottom of piston rod, bottom valve is arranged at clutch release slave cylinder bottom, oil sealing guidance set is arranged at the top of the corresponding clutch release slave cylinder of piston rod and oil storage cylinder, dust-proof cover is arranged at the outside of oil storage cylinder, wherein dust-proof cover is next for vibration damper is also to have played very important effect, can prevent that particle or dust from entering into makes fluid become muddy and can prevent that piston rod and oil sealing guidance set are scratched in vibration damper, yet, existing dust-proof cover itself and imperfection, it is just installed to oil storage cylinder one end, the part of piston rod outside clutch release slave cylinder can not be completely capped, therefore still can not be well protected, and when piston rod moves down, its surface meeting some particles of adhesive tape or dust enter in clutch release slave cylinder, when thump is excessive, dust-proof cover is also easily loosening even to come off, thereby affect the working stability of vibration damper.
Model utility content
The technical problems to be solved in the utility model has been to provide a kind of cylindrical automobile shock absorber; it has solved existing vibration damper due to dust-proof cover imperfection; make piston rod can not be well protected and its surperficial can some particles of adhesive tape or dust enter in clutch release slave cylinder and make fluid become muddy; and when thump is excessive; dust-proof cover is also easily loosening even to come off, thereby affects the working stability of vibration damper.
In order to solve the existing problem the utility model of background technique, adopted following technological scheme: a kind of cylindrical automobile shock absorber, comprise clutch release slave cylinder, oil storage cylinder, piston rod, piston valve, bottom valve, oil sealing guidance set, dust-proof cover, described piston valve is sheathed on the bottom of piston rod, described bottom valve is arranged at clutch release slave cylinder bottom, described oil sealing guidance set is arranged at the top of the corresponding clutch release slave cylinder of piston rod and oil storage cylinder, described dust-proof cover is arranged at the outside of oil storage cylinder, described piston rod part connects a upper rings by screw-thread fit, described piston rod top connects a rubber bushing by described upper rings, described dust-proof cover is arranged between oil storage cylinder and rubber bushing, its one end Extender Card is loaded on oil storage cylinder, the other end presses on rubber bushing.
By adopting technique scheme; dust-proof cover is installed in oil storage cylinder by one end; the other end presses on rubber bushing; by piston rod, the part outside clutch release slave cylinder all covers dust-proof cover like this; it is well protected; neither can be scratched and also can not carry a large amount of particles or dust and make fluid keep pure; thereby do not affect the damping efficiency of vibration damper; and upper rings arrange can be better the fixing position of rubber bushing; thereby also can dust-proof cover is better fixing; make it be difficult for getting loose, strengthen it and use work efficiency.
Further setting of the present utility model: described upper rings is provided with an annular groove along outer surface, described dust-proof cover is provided with an annular recess and compresses and be socketed on annular groove.
By adopting technique scheme, the annular recess on dust-proof cover can well be socketed on the annular groove of upper rings outer surface, and dust-proof cover can further be fixed like this, makes it more be difficult for getting loose, and is conducive to the normal operation of vibration damper.
Further setting of the present utility model: described dust-proof cover is to have flexible plastics to make.
By adopting above-mentioned technological scheme, when piston rod moves up or down, dust-proof cover just can upwards stretch or to lower compression, because dust-proof cover has good elasticity, make it be difficult for producing distortion, is not easy to damage.
The beneficial effects of the utility model are: cylindrical automobile shock absorber of the present utility model is by the improvement to this body structure of dust-proof cover and assembling; dust-proof cover can the part outside clutch release slave cylinder all be covered piston rod; it is well protected; neither can be scratched and also can not carry a large amount of particles or dust and make fluid keep pure; thereby do not affect the damping efficiency of vibration damper; and can dust-proof cover is better fixing by upper rings and rubber bushing are set; make it be difficult for getting loose, strengthen it and use work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model cylindrical automobile shock absorber embodiment's structural representation.
