Abstract
The utility model relates to a vibration absorber for automobiles, which comprises a guide positioning steel ball 6 of a piston, the guide positioning steel ball of the piston is inlaid around the circumference of the outer side wall 10 of a piston 3, and a steel jacket 1 is filled with vibration absorber oil 7. The steel jacket is filled with the vibration absorber oil, so, the heat generated by the friction between a piston rod 2 and oil seal 4 is absorbed in time, the hard friction between the piston rod and the oil seal is reduced, and the oil seal and the piston rod can not be damaged in a short time. The friction between the piston and the inner wall of the steel jacket is not direct, so, the piston and the steel jacket are not easy to abrase, the vibration absorber oil filled in the steel jacket can make the movement from top to bottom of the piston in the vibration absorber soft, the vibration absorption effect is good, and three to five years of the integral service life can be reached.
Description
The utility model belongs to vehicular spare parts.
There are following two shortcomings in existing automobile absorber, the one, owing to there is not oil between piston upper surface and the steel bushing, cause the heat that friction produces between piston rod and the oil sealing to be difficult for disappearing, very easily piston rod and oil sealing are damaged, oil sealed damages and makes in the bumper and can not seal, and makes bumper lose damping effect; The 2nd, between piston and the steel bushing since directly friction can produce the slit, make during work oil from the slit to external leakage, make its work deleterious, worked about three months and will scrap.
The purpose of this utility model is a kind of automobile absorber of development, and this bumper should have the characteristics of life-span length, good damping effect.
The utility model comprises steel bushing 1, piston rod 2, piston 3, oil sealing 4, steel bushing lid 5, it also comprises piston guide positioning ball 6, piston 3 is fixed on the lower end of piston rod 2, oil sealing 4 is fixed on the centre of steel bushing lid 5, steel bushing lid 5 is fixed on the top of steel bushing 1, the centre that oil sealing 4 is passed in the upper end of piston rod 2 is exposed at the outside of steel bushing lid 5, fills with anti-shock fluid 7 in the steel bushing 1, piston guide positioning ball 6 be set in piston 3 lateral wall 10 around on.
The utility model is filled with anti-shock fluid owing in the steel bushing, thus the heat that friction between piston rod 2 and the oil sealing 4 produces in time can be absorbed, and minimizing hard grind wiping between the two, and do not cause oil sealing and piston rod to damage at short notice.Again owing to stud with guide-localization steel ball 6 around the lateral wall of piston 3, make piston 3 and the not directly friction of steel bushing 1 inwall, so piston and steel bushing are not easy to wear, and the anti-shock fluid of filling with in the steel bushing 7 more can make the up-and-down movement of bumper inner carrier soft, good damping effect, bulk life time can reach 3-five years, and it also has the low advantage of cost.
Fig. 1 is a main cutaway view of the present utility model; Fig. 2 is the birds-eye view of piston 3; Fig. 3 is the lateral plan of piston 3.
Embodiment one: present embodiment is made up of steel bushing 1, piston rod 2, piston 3, oil sealing 4, steel bushing lid 5, piston guide positioning ball 6.Piston 3 is fixed on the lower end of piston rod 2, oil sealing 4 is fixed on the centre of steel bushing lid 5, steel bushing lid 5 is fixed on the top of steel bushing 1, the centre that oil sealing 4 is passed in the upper end of piston rod 2 is exposed at the outside of steel bushing lid 5, fill with anti-shock fluid 7 in the steel bushing 1, half of piston guide positioning ball 6 is embedded in the sidewall pit 9 of piston 3, and second half of piston guide positioning ball 6 is clipped between the inwall of piston 3 and steel bushing 1.
Embodiment two: the difference of present embodiment and embodiment one is vertically to have at least two oil throughs 8 on piston 3, and the size in what and aperture of oil through 8 is directly proportional with the load carrying ability of car.Other composition is identical with embodiment one with annexation.
Embodiment three: the difference of present embodiment and embodiment two is that the last bottom of the sidewall 10 of piston 3 respectively has a leaning angle 11.Other composition is identical with embodiment two with annexation.
