Abstract
The utility model discloses a novel automobile damper, which comprises a cylinder body, a cylinder sleeve, a piston rod and a piston. Steel balls for guiding and positioning are embedded on the periphery of the outer side wall of the piston. An oil seal is equipped on the cylinder sleeve. Hydraulic oil is filled inside the cylinder body. A buffer ring is equipped on the piston rod. By filling the cylinder body with the hydraulic oil, the novel automobile damper provided in the utility model can absorb the heat generated by the friction between the piston rod and the oil seal and further alleviate the hard friction between the piston rod and the oil seal. The oil seal and the piston rod are then prevented from being damaged in a short time. The steel balls embedded on the outer side wall of the piston and applied for guiding and positioning prevent direct friction between the piston and the inner wall of the cylinder body. Thus the piston and the cylinder body are not prone to wearing. The hydraulic oil filled inside the cylinder body makes the piston inside the damper vertically move in a soft way. Furthermore, the novel automobile damper has the advantages of good damping effects and low cost.
Description
Technical field
The utility model relates to a kind of automobile and motorcycle and uses shock-absorption device, particularly a kind of new automobile vibration damper.
Background technique
The vibration damper that present automobile, motorcycle use number extremely greatly is that a lubricant oil is the damping medium; There are following two shortcomings in existing vibration damper; The one, there is not oil between piston upper-end surface and the cylinder sleeve, cause the difficult disappearance of fricative heat between piston rod and the oil sealing, very easily piston rod and oil sealing are damaged; The damage of oil sealing causes can not sealing in the vibration damper, and makes vibration damper lose damping effect; The 2nd, because direct wearing and tearing can produce the slit, oil is outwards revealed from the slit between piston and the cylinder sleeve, make its work variation, reduced working life.
The model utility content
The purpose of the utility model is in order to overcome the problem problem in above-mentioned vibration damper sealing and life-span, a kind of new automobile vibration damper to be provided.
For achieving the above object; The method that the utility model adopts is: a kind of new automobile vibration damper; Comprise cylinder body, cylinder sleeve, piston rod and piston, on around the outer side wall of piston, stud with the steel ball that is used for guide-localization, on described cylinder sleeve, be provided with oil sealing; In described cylinder body, be full of hydraulic oil, on described piston rod, be provided with buffer ring.
As a kind of improvement of the utility model, described piston is provided with vertical oil through.
As a kind of improvement of the utility model, described half that apply flexibly in the steel ball of guide-localization is embedded in the sidewall pit of piston, and second half of steel ball is clipped between the inwall of piston and described cylinder body.
As a kind of improvement of the utility model, described oil through is provided with at least two.
The beneficial effect of the utility model is:
The utility model is through filling with hydraulic oil in cylinder body, thus can the fricative heat between piston rod and the oil sealing in time be absorbed, and reduce hard friction between the two, and do not cause oil sealing and piston rod to damage at short notice.Make not direct friction of piston and inboard wall of cylinder block owing to stud with the guide-localization steel ball around the outer side wall of piston again; So piston and cylinder body are not easy to wear; And the hydraulic oil of filling with in the cylinder body more can make moving up and down of the interior piston of vibration damper soft, good damping effect, and with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein each parts is:
1 piston rod, 2 buffer rings
3 steel balls, 4 pistons
5 hydraulic oil, 6 cylinder bodies
7 oil throughs, 8 cylinder sleeves
9 oil sealings.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described;
Like the described a kind of new automobile vibration damper of Fig. 1; Comprise cylinder body 6, cylinder sleeve 8, piston rod 1 and piston 4; On around the outer side wall of piston 4, stud with the steel ball 3 that is used for guide-localization; On described cylinder sleeve 8, be provided with oil sealing 9, in described cylinder body 6, be full of hydraulic oil 5, on described piston rod 1, be provided with buffer ring 2.
Described piston 4 is provided with vertical oil through 7, and described oil through 7 is provided with at least two.
Described half that apply flexibly in the steel ball 3 of guide-localization is embedded in the sidewall pit of piston 4, and second half of steel ball 3 is clipped between the inwall of piston 4 and described cylinder body 6.
The utility model is through filling with hydraulic oil in cylinder body, thus can the fricative heat between piston rod and the oil sealing in time be absorbed, and reduce hard friction between the two, and do not cause oil sealing and piston rod to damage at short notice.Make not direct friction of piston and inboard wall of cylinder block owing to stud with the guide-localization steel ball around the outer side wall of piston again; So piston and cylinder body are not easy to wear; And the hydraulic oil of filling with in the cylinder body more can make moving up and down of the interior piston of vibration damper soft, good damping effect, and with low cost.
The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
