According to the automobile damper with the anti-dust device, the dust shield is made of the elastic materials, so that the dust shield can be lengthened and restore along with extending and retracting motion of the piston rod, and work requirements of the automobile damper are met. Meanwhile, due to the fact that the clamping hoops are simple in structure and convenient to operate, the clamping hoops can be used for sealed cooperation of the two open ends of the dust shield and the piston rod and the cylinder respectively, the dust shield can be conveniently mounted and dismounted, and using and maintaining cost is lowered.
Description
Technical field
The utility model relates to a kind of automobile absorber, especially a kind of automobile absorber with dust guard.
Background technique
For the vibration of vehicle frame and vehicle body is decayed rapidly, improve smoothness and the travelling comfort of automobile running, vibration damper is generally all housed on automobile suspension system.And vibration damper is the rapid wear accessory in automobile using process, vibration damper work quality, by directly affecting the stationarity of automobile running and the life-span of other parts, therefore should make vibration damper often in good working order.
General existing automobile absorber is all with dust-proof cover, but dust-proof cover of the prior art mostly is open (non-vibration damper and spring are integrated), and dust-proof cover bottom is open, and has certain interval between vibration damper urceolus.Therefore, there is many technical problems in damper dust-proof cover of the prior art, as: 1, dust or silt are deposited on oil sealing and piston rod by lower openings, cause the scuffing of piston rod and oil sealing, cause leakage of oil, thereby reduce working life; 2, cause vibration damper hair fastener, when serious, will make vibration damper cisco unity malfunction, greatly affect the comfort property of car load.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of can thoroughly isolate sand and dust, and installs and stablize, and there will not be the automobile absorber with dust guard of slippage.
The utility model solves the technological scheme that its technical problem adopts: a kind of automobile absorber with dust guard, comprise cylinder body, piston and piston rod, and the end being positioned on this piston rod outside cylinder body is positioning end, described dust guard comprises:
Dust-proof cover, is the tubular structure of both ends open, and is sheathed on outside piston rod and cylinder body;
Clip, quantity is two;
A described dust-proof cover wherein opening end is fixed on piston rod positioning end by a clip sealing, and another opening end is fixed on cylinder body by another clip sealing, and described dust-proof cover is made by elastic material.
Further be set to: on described piston rod positioning end, offer the draw-in groove of establishing for clip card.
Adopt technique scheme, by the cooperation of draw-in groove and clip, avoid thus the slip of clip on piston rod positioning end, guaranteed that dust-proof cover does not slide with the motion of piston rod, to meet the normal use of dust-proof cover under the state of working long hours.
Further be set to: described in state and on cylinder body, offer the draw-in groove of establishing for clip card.
Adopt technique scheme, by the cooperation of draw-in groove and clip, avoid thus the slip of clip on cylinder body, guaranteed that dust-proof cover does not slide with the effect of pulling force, to meet the normal use of dust-proof cover under the state of working long hours.
Further be set to: the position near positioning end on described dust-proof cover is provided with some air holes, and the diameter of this air hole is less than 0.5mm.
Adopt technique scheme, dust-proof cover is to be sheathed on hermetically on piston rod and cylinder body, when guaranteeing piston rod movement, the air hole that is less than 0.5mm by some diameters are set is realized internal and external pressure balance, and the diameter of air hole selects especially and is less than 0.5mm, therefore avoid to greatest extent entering of impurity and dust.
The beneficial effects of the utility model are: dust-proof cover is that elastic material is made, thus dust-proof cover can along with the fore and aft motion of piston rod, be elongated and recover, thereby meet the need of work of automobile absorber.Meanwhile, because yoke configurations is simple, and easy to operate, therefore realize dust-proof cover two opening ends by clip, coordinate with piston rod and cylinder body seal respectively, can guarantee the convenience of dust-proof cover installation and removal, and reduce operation and maintenance cost.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's explosive view.
Fig. 2 is the utility model embodiment's erection drawing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, 2, the present embodiment comprises the cylinder body 1 with piston cavity, and piston is installed in piston cavity, is connected with piston rod 2 on piston, and piston rod 2 wherein one end extends to outside cylinder body 1 and forms positioning end 21.In order to protect, avoid entering dust between piston rod 2 and cylinder body 1 gap, the utility model also includes dust guard 3, this dust guard 3 comprises the dust-proof cover 31 of tubular structure and both ends open, this dust-proof cover 31 is sheathed on outside piston rod 2 and cylinder body 1, wherein, dust-proof cover 31 is made for the good rubber material of elasticity, the bullet performance guarantee autoreduplication stretching that well refers to this rubber material herein reply and indeformable or lax.Dust guard 3 also includes clip 32, and this clip 32 is used to 31 liang of opening ends of dust-proof cover to be pressed in respectively on the perisporium of piston rod 2 and cylinder body 1, thereby realizes being sealed and matched of dust-proof cover 31 and piston rod 2 and cylinder body 1.Clip 32 is comparatively ripe on the market securing meanss, is generally two arc hoop bodies and forms, and mutually fastens and is bolted, or by hinging shaft and bolt, fix respectively between two arc hoop bodies between two arc hoop bodies.But no matter clip is which kind of form or structure, all falls within protection domain of the present utility model.
For fear of clip 32, on piston rod 2 or cylinder body 1, slide, so offer respectively the draw-in groove 4 of establishing for clip 32 cards on the perisporium of piston rod 2 and cylinder body 1, also therefore guarantee that dust-proof cover 31 does not slide on piston rod 2 or cylinder body 1, to meet the normal use of dust-proof cover 31 under the state of working long hours.In addition, when guaranteeing piston rod 2 motion, dust-proof cover 31 internal and external pressure balances, so the position near positioning end is provided with some air holes 311 on dust-proof cover 31, the diameter of this air hole 311 is 0.5mm.And obtain according to normal experiment, in the working environment of automobile absorber, the diameter that the diameter of dust granules is generally less than air hole 311 is selected especially and is less than 0.5mm, therefore can avoid to greatest extent entering of impurity and dust.
In the utility model, dust-proof cover 31 is made for elastic material, thus dust-proof cover 31 can be elongated and recover along with the fore and aft motion of piston rod 2, thereby meet the need of work of automobile absorber.Meanwhile, because clip 32 is simple in structure, and easy to operate, therefore realize 31 liang of opening ends of dust-proof cover by clip 32, be sealed and matched with piston rod 2 and cylinder body 1 respectively, can guarantee the convenience of dust-proof cover 31 installation and removal, and reduce operation and maintenance cost.
