Abstract
The utility model discloses a shock absorber which comprises a cylinder body, a piston, a piston rod and a dustproof device. The end, located on the cylinder body, of the piston rod is the locating end. The dustproof device comprises a plurality of dustproof sleeves and a shock absorbing spring. Each dustproof sleeve comprises a sleeve bottom plate and a sleeve side wall, wherein a sleeve cavity is formed by the sleeve bottom plate and the sleeve side wall in an enclosure mode. Each dustproof sleeve bottom plate is provided with a sliding through hole matched with the piston rod. The adjacent dustproof sleeves are matched. The sleeve bottom plate of the dustproof sleeve of the uppermost end makes contact with the locating end, and the inner diameter of the sleeve cavity of the dustproof sleeve of the lowermost end is matched with that of the cylinder body. The shock absorbing spring is arranged on the piston rod in the sleeve cavities in a sleeved mode. One end of the shock absorbing spring is fixedly connected with the inner walls of the sleeve bottom plates. The dustproof sleeves in the dustproof device have the good dustproof effect and the certain protecting effect, and can protect the piston rod from being influenced by the external force; due to the shock absorbing spring, the whole dustproof device can have a certain shock absorbing function in the contracting process.
Description
Technical field
The utility model relates to a kind of automobile absorber technical field, and more particularly, it relates to a kind of vibration damper.
Background technique
Vibration damper has spread in the various traffic tool now, vibration damper is the impact bringing for alleviating road surface, absorb rapidly the vibrations that produce while jolting, the normal travelling state that vehicle is recovered, in existing suspension system, the effect of vibration damper is very important, so just need to drip vibration damper protection, so just produce the vibration damper with dust-proof cover, but generally being, existing dust-proof cover there is ripple or the bellows of the staggered sidewall of tooth shape, such dust-proof cover, just there is dustproof effect, can not strengthen the shock-absorbing function of vibration damper, and easily aging breaking of such dust-proof cover, in the time of vibration damper and other article generation shock, because material is softer, easily deform, so the protective action of such dust-proof cover is not strong, in sum, just need to improve above defect.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of vibration damper with dust reduction capability.
For achieving the above object, the utility model provides following technological scheme: a kind of vibration damper, comprise cylinder body, piston, piston rod and dust guard, the end being positioned on this piston rod outside cylinder body is positioning end, dust guard comprises some dustproof sleeves and damping spring, dustproof sleeve comprises cover tube end plate and sleeve lateral wall, cover tube end plate and sleeve lateral wall surround sleeve cavity, described dirt-proof boot tube end plate is provided with the slip through hole suitable with piston rod, adjacent dustproof sleeve is suitable, cover tube end plate and the positioning end of dustproof sleeve are topmost inconsistent, sleeve cavity internal diameter and the cylinder body of dustproof sleeve are bottom suitable, damping spring is enclosed within on the piston rod in sleeve cavity, one end is fixedly connected with sleeve plate inner wall.
By adopting technique scheme, the dustproof sleeve in dust guard can not only have good dust-proof effect, but also has certain protection effect, can protect piston rod can not be subject to the impact of external force; And damping spring just can allow whole dust guard possess certain shock-absorbing function in shrinking.
The utility model is further set to: described cover tube end plate is provided with vent.
By adopting technique scheme, in the time that dust guard shrinks, the air in each sleeve cavity can be discharged from timely, allows the dust guard be that to shrink be smooth and easy more, the shock-absorbing function of the product of increase greatly.
The utility model is further set to: described sleeve lateral wall inner side is provided with some rolling grooves, and the axis of described rolling groove and piston rod is parallel to each other, and sleeve lateral wall outside is provided with the rolling element suitable with rolling groove.
By adopting technique scheme, increase the annexation between adjacent dustproof sleeve, and controlled dustproof sleeve at movement direction and shift motion, can effectively protect dust guard, increase the working life of product.
The utility model is further set to: the described positioning end resistance surface inconsistent with overlapping tube end plate is provided with the first cushion pad, and cylinder body one end in dustproof sleeve is provided with the second cushion pad.
By adopting technique scheme, can effectively alleviate the impact of dust guard to positioning end and cylinder body, can effectively protect all parts on vibration damper, increase life of product, and effective noise decrease.
