Description
Technical field
The utility model relates to guider technical field, particularly relates to a kind of guide device used in automobile shock absorber.
Background technique
Automobile is through uneven road surface, although the shock-absorbing spring in shock absorbing apparatus can filter out the vibrations on road surface, spring itself still has reciprocal jump, and vibration damper is just being used to the reciprocal jump suppressing this spring.The main structure of vibration damper inserts in cylinder with the piston rod of piston, is full of oil, piston has throttle orifice in cylinder, and the oil in two-part space separated by piston can be complemented each other.The working principle of vibration damper is when vehicle frame and vehicle bridge or when there is relative movement by vibrations between vehicle body and vehicle bridge, piston in vibration damper moves up and down, fluid in vibration damper chamber just flows in another chamber from a chamber through different holes repeatedly, friction now between hole wall and fluid and the intermolecular interior friction of fluid form damping force to vibrations, make thump Conversion of Energy be fluid heat energy, then be dispersed in air by shock absorber.
Guider is one of strength member in vibration damper, mainly the piston rod be slidably mounted in shock absorber working cylinder is play the guiding role, ensure the smoothness of piston in running, and by the oil-through hole of guider, unnecessary shock absorber oil being transported in oil storage cylinder in piston movement process, guarantee clutch release slave cylinder is communicated with oil storage cylinder.The guider mesa sidewall lower end circumferentially of prior art is vertical, and it is not very convenient that whole like this guider assembles up; And the piston rod mounting hole of prior art guider is by tool sharpening out, but after processing cutter exit not very convenient; And prior art guider in use, due to long-time use, some oil can be remained at piston rod surface, oil sealing pressure increase can be caused when using like this, and then reduce the working life of guider.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of easy to assembly, withdrawing convenient and the guide device used in automobile shock absorber that working life is higher.
The technological scheme that the utility model adopts is: a kind of guide device used in automobile shock absorber, comprise guider body, step surface is provided with outside described guider body, described step surface comprises the small stair face of large diameter large step surface and minor diameter, described large step surface is connected by inclined-plane with small stair face, described guider body inside is provided with the oil outlet flowed out for fluid, for install piston rod mounting hole and to be interference fitted in mounting hole and with the lining of piston rod sliding fit, outside described guider body, the lower end of small stair face sidewall is provided with a plane of inclination and chamfering, and described plane of inclination is connected by vertical plane with between chamfering, a tool withdrawal groove for cutter withdrawing is provided with in described mounting hole, and described lining is provided with multiple salient point for being wiped off by the fluid that piston rod remains.
Adopt above structure compared with prior art, the utility model has the following advantages: arrange a plane of inclination and chamfering in small stair face side wall lower ends, and plane of inclination is connected by vertical plane with chamfering, convenient during such guider assembling; And a tool withdrawal groove is set on mounting hole, after processing mounting hole like this, cutter withdrawing is more convenient, and arranges salient point on lining, and when such piston rod slides in lining, the fluid on piston rod can be wiped off by salient point.
As preferably, described tool withdrawal groove is the circular groove of circular arc cross-sections, and is positioned at the upper end of mounting hole.Withdrawing better effects if is set like this.
As preferably, described mounting hole lower end is provided with chamfering.Arranging lining like this, to be fit into mounting hole more convenient.
As preferably, described multiple salient point composition two circle salient point circles, described two circle salient point circles are separately positioned on the upper and lower two ends of lining, and the salient point in each salient point circle distributes along lining even circumferential.Such setting, the fluid on piston rod can better be cleaned out, and can not affect the normal work of piston rod.
