Abstract
The utility model belongs to the technical field of automobile fittings, more particularly relates to a buffer pressure spring and a shock absorber with the buffer pressure spring, which mainly solves the technical problem in the prior art that a bumping block made of materials of rubber, polyurethane, and the like can cause a piston rod to be worn and bump against a bottom, and uses a metal compression spring to replace the bumping block made of organic materials such as rubber, polyurethane, and the like. The utility model provides the buffer pressure spring which is arranged between the top end of the piston rod and the upper end of an outer cylinder; a fixed gap is kept between the inside diameter of the buffer pressure spring and the surface of the piston rod; the buffer pressure spring can be installed at the upper end of the outer cylinder of the shock absorber and can also be installed at the top end of the piston rod. The shock absorber with the buffer pressure spring makes up the technical deficiency that the bumping block causes the piston rod to be worn and bump against the bottom.
Description
Technical field
The utility model belongs to the auto parts machinery technical field, particularly relates to purpose and is, can reduce the piston lever of reducer friction and avoid piston rod to hit the buffering stage clip and the vibration damper with described buffering stage clip at the end.
Background technique
At present, known automobile absorber buffer stopper mainly is rubber, polyamine fat an or the like made, because these materials exist intrinsic creep and embrittlement character, distortion is bigger after making the buffer stopper pressurized, add that it is to be slidingly matched with piston rod that the back is installed, so just two problems occur, the one, piston rod is subjected to too much friction when work, particularly during dust accumulation, serious wear.The 2nd, after buffer stopper embrittlement was lost efficacy, the direct shock-absorber of beat of piston rod meeting bottom was damaged rebuilt valve or compression valve easily.The automobile two-man act secondary vibration damper (CN2589240Y) that Chinese patent is announced, it increases damping effect with the two-man act structure, because spring cup and piston rod are slidingly matched, though can avoid piston rod directly to clash into the bottom, the piston rod surface friction still exists during piston rod work.Chinese patent has also been announced dustproof vibration damper (CN2814010Y), and it with buffer stopper, has eliminated the slide relative friction of piston rod and buffer stopper on the body of rod of piston rod.Chinese patent is also announced a kind of vibration damper (CN200943664Y) with the compression stop collar, and it is provided with the compression stop collar between rebuilt valve and compression valve, can avoid bump, has reduced loosening hidden danger.Each has only solved a problem these several technology, and complex structure, and implementation cost is higher.
Summary of the invention
The utility model provides a kind of vibration damper that cushions stage clip and have described buffering stage clip, it mainly is to solve prior art by rubber, the buffer stopper of polyamine fat or the like made, cause piston rod wearing and tearing and piston rod to hit technical problems such as the end, its essence is with the metal pressure spring and replace rubber, the buffer stopper of polyamine fat or the like organic material, the elasticity of stage clip directly plays buffer function, the hardness that the metal stage clip is had makes it be compressed to constant spacing not the hitting at the end of stop back piston bar, stage clip does not contact with piston rod and eliminates too much friction, both eliminated the suffered too much friction of piston rod with this, avoid piston rod to hit the end again, prolong the vibration damper spreadable life.
The utility model provides a kind of buffering stage clip, and it is located between piston rod top and the urceolus upper end, and described buffering stage clip internal diameter and piston rod surface are maintained fixed the gap, and described buffering stage clip can be installed in vibration damper urceolus upper end, also can be installed in the piston rod top.Vibration damper with described buffering stage clip has remedied the technical deficiency that existing buffer stopper causes the piston rod wearing and tearing and hits the end.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Description of reference numerals: piston rod 1, buffering stage clip 2, urceolus 3.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, sort buffer stage clip and the vibration damper with described buffering stage clip mainly comprise piston rod 1, buffering stage clip 2, urceolus 3, between described piston rod 1 top and urceolus 3 upper ends, be provided with buffering stage clip 2, described buffering stage clip 2 internal diameters and piston rod 1 surface are maintained fixed the gap.
Claims (3)
1, buffering stage clip is characterized in that: between described piston rod 1 top and urceolus 3 upper ends, be provided with buffering stage clip 2.
2, according to the described buffering stage clip of claim 1, it is characterized in that: described buffering stage clip 2 internal diameters and piston rod 1 surface are maintained fixed the gap.
3, a kind of vibration damper that cushions stage clip is characterized in that comprising the described buffering stage clip of claim 1 to 2.
