for achieving the above object, the utility model provides following technological scheme: a kind of vehicle shock absorber with dust-proof cover, comprise piston rod, oil storage cylinder and clutch release slave cylinder, clutch release slave cylinder is coaxial to be arranged in oil storage cylinder, described piston rod is arranged in clutch release slave cylinder, the end of piston rod is provided with the piston valve assembly, the top of described oil storage cylinder is the vibration damper sealing, the bottom of clutch release slave cylinder is provided with the bottom valve assembly, be provided with guider between oil storage cylinder and piston rod, guider be set on clutch release slave cylinder and with the clutch release slave cylinder interference fit, with the oil storage cylinder Spielpassung, be provided with oil sealing between guider and piston rod, oil sealing and piston rod are flexibly connected, it is characterized in that: described oil sealing edge is provided with the turnup structure that is sealed and matched with vibration damper sealing and guider, turnup structure is provided with seal washer towards guider one side, and described vibration damper sealing is provided with dust-proof cover, dust-proof cover is set on the oil storage cylinder outer wall.
The utility model further is set to: described dust-proof cover includes the installation sleeve that is fixedly set on oil storage cylinder, and installation sleeve is extended with the flanging mouth that turns up, and the inwall of flanging mouth is the circular arc wall that contacts sealing with piston rod.
After adopting above-mentioned the setting, the sealing between dust-proof cover and piston rod is reliable, prevents that effectively dust and particle from falling in vibration damper.
Further be set to: the installation sleeve madial wall of described dust-proof cover is provided with hemispheric positioning convex again, and corresponding oil storage cylinder outer wall is provided with the positioning groove that coordinates with positioning convex.
The above-mentioned setting down, the installation of dust-proof cover coordinates reliable, and sealing effect is better.
Further be set to: be provided with guide liner between described guider and clutch release slave cylinder, described guide liner is set on piston rod again.
The above-mentioned setting down, between guider and piston rod for being slidably connected, adopt above-mentioned further arrange after, make guider more flexible with relative activity between piston rod.
By adopting technique scheme; the oil sealing of vehicle shock absorber adopts turnup structure; be sealed and matched with guider and oil storage cylinder; and the turnup structure pad is established seal washer, is provided with dust-proof cover in the vibration damper sealing, makes vehicle shock absorber obtain repeatedly seal protection; sealing is improved; this turnup structure has increased the bearing capacity of vibration damper sealing part simultaneously, improves the internal pressure of bearing of vehicle shock absorber, thereby has improved the durability of product.
Below in conjunction with accompanying drawing, the utility model is further described.
