Abstract
The utility model discloses a piston rod improved structure of an automobile shock absorber. The automobile shock absorber comprises a shell body and a bush, a dustproof cover is arranged at the upper end of the shell body, the lower end of the shell body is connected with the bush, an oil cylinder is arranged inside the shell body, a piston rod and a piston valve which is connected with the bottom of the piston rod are arranged inside the oil cylinder, a guide holder is arranged at the upper end of the oil cylinder, a bottom valve is arranged on the bottom of the oil cylinder, an annular groove is arranged in the piston rod, a stopping block is embedded inside the groove and placed between the piston valve and the guide holder, and a rebound block is further fixedly arranged on the upper end face of the stopping block. Due to the fact that the stopping block and the rebound block are arranged on the piston rod, the piston valve and the guide holder are isolated, the piston valve is prevented from being directly contacted with the guide holder, the probability of damaging the piston valve is lowered, the service life of the automobile shock absorber is prolonged, and the safety and the comfort of the shock absorber are improved.
Description
Technical field
The utility model relates to a kind of vibration damper, particularly a kind of piston lever of reducer for automobile structure-improved.
Background technique
Automobile absorber, when proper functioning, piston rod drives piston valve and moves up and down in internal oil pipe, because general hydra-shock absorber is for its effect that rebounds, inside all is filled with a certain amount of low-pressure gas, under the free state, piston valve all can be extruded to the top, at severe jolt or other in emergency circumstances, do not stop between piston valve and the guide holder, directly contact causes piston valve to damage, and then makes vibration damper lose damping effect.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides between a kind of piston rod upper piston valve that solves existing automobile absorber and the guide holder and has not stopped, directly contact causes the piston lever of reducer for automobile structure-improved of the problem of piston valve damage.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of piston lever of reducer for automobile structure-improved, comprise housing and lining, described housing upper end is provided with dust cover, the housing lower end connects lining, be provided with oil cylinder in the housing, piston rod and the piston valve that is connected the piston rod bottom are installed in the described oil cylinder, the oil cylinder upper end is equipped with guide holder, the oil cylinder bottom is equipped with bottom valve, described piston rod is provided with the groove of annular, be embedded a stop piece in the described groove, described stop piece is between piston valve and guide holder, and the stop piece upper-end surface also fixedly mounts a bounce-back piece.
As further improvement of the utility model, described bounce-back piece is made by elastic material.
The beneficial effects of the utility model are: because the utility model has been adorned stop piece and bounce-back piece on piston rod, piston valve and guide holder are separated, prevented that piston valve from directly contacting with guide holder, reduce the possibility of piston valve damage, improved working life and the Security and the travelling comfort of vibration damper.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Fig. 1 has shown the structure improved a kind of mode of execution of a kind of piston lever of reducer for automobile of the utility model, comprise housing 1 and lining 2, described housing 1 upper end is provided with dust cover 10, housing 1 lower end connects lining 2, be provided with oil cylinder 3 in the housing 1, piston rod 4 and the piston valve 5 that is connected the piston rod bottom are installed in the described oil cylinder 3, oil cylinder 3 upper ends are equipped with guide holder 6, the oil cylinder bottom is equipped with bottom valve 7, described piston rod 4 is provided with the groove of annular, be embedded a stop piece 8 in the described groove, described stop piece 8 is between piston valve 5 and guide holder 6, and stop piece 8 upper-end surfaces also fixedly mount a bounce-back piece 9, described bounce-back piece 9 is made by elastic material, automobile absorber is when proper functioning, piston rod 4 drives piston valve 5 and moves up and down in internal oil pipe, the stop piece of fixing on the piston rod 48, can control piston bar 4 in the indoor movement travel of cylinder, length when being the vibration damper free state, because general hydra-shock absorber is for its effect that rebounds, inside all is filled with a certain amount of low-pressure gas, under the free state, piston valve 5 all can be extruded to the top, so the position of stop piece 8 is in 6 of piston valve 5 and guide holder, piston valve 5 and guide holder 6 direct contact have the under special circumstances been prevented, and piston valve 5 is caused damage, and then cause vibration damper to lose damping effect, the bounce-back piece 9 that fits together with it is elastic material, making it becomes Elastic Contact with contacting of guide holder 6, its Security and working life have also been guaranteed more, stop piece 8 is fixed on the groove that piston rod designs in advance by external force pressurization, and 9 of bounce-back pieces directly are placed on the piston rod after fixing stop piece and get final product.Also available spring substitutes the bounce-back piece when certainly, having relatively high expectations.
