Abstract
The invention discloses an improved shock attenuation device which comprises a damper shell, a piston seat, a spring seat II welded on the damper shell, and a piston rod fixedly installed on the piston seat, wherein a movable baffle plate is arranged between the upper end of the shell and a piston head; an air damping hole is formed in the movable baffle plate; an air chamber is formed above the movable baffle plate; an elastic layer is embedded inside the damper shell; two sides of the piston head are matched with the elastic layer; a W-shaped piece is installed on the piston rod; and two sides of the W-shaped piece are matched with the elastic layer. By installing the W-shaped piece on the piston rod, the problem of deviation of the axis of the piston rod and the problem of friction in the running process can be relieved; due to a buffer layer and the embedded elastic layer, the leakage of oil liquide and the impact of the W-shaped piece to the bottom during the movement of the piston are effectively reduced, the use effect is improved, and the service life is prolonged.
Description
Technical field
The present invention relates to safety installation and make the field, be specifically related to a kind of improved damping device on the Motor Vehicle.
Background technique
Along with the raising of quality of life, the Motor Vehicle such as car, motorcycle generalize gradually, and on these traffic tool, damping device is that a kind of application is installed very widely.
Common damping device, its piston rod directly cooperates with housing, can produce noise in the process of moving, and more seriously owing to directly cooperating, its wearing and tearing are larger, and then cause oil liquid leakage, not only pollute miscellaneous part, even may bring life harm.In addition in the process of moving because the materials such as dust have very strong being adsorbed property, dust etc. can be adsorbed onto around the piston rod during piston rod to-and-fro motion, and then be brought into fluid, thereby polluted fluid, affect damping effect, in the situation that serious, even can stop up damping hole, and then can't play damping effect.
Summary of the invention
The present invention is directed to the deficiencies in the prior art part, a kind of new improved damping device is provided.
The scheme that the present invention solves the prior art problem is: a kind of improved damping device, comprise the damper housing, piston seat, be welded on the spring seat two on the damper housing, be fixedly mounted on the piston rod on the piston seat, spring seat one, between spring seat one and the spring seat two return spring is installed, piston head is installed in the top of piston rod, piston head is provided with damping hole, be provided with movable baffle plate between housing upper end and the piston head, movable baffle plate baffle plate is provided with the air damping hole, the top is air cavity, be bumped into elasitic layer in the damper housing, match with elasitic layer in the both sides of piston head, hard-wired chevron part on the piston rod, match with elasitic layer in the both sides of chevron part, the hilltop, chevron part both sides is with the slope, the fluid adsorption piece is installed in the joint of piston rod and piston seat, such as sponge, the material of buffer layer is foam, rubber or sponge, high elasticity threaded folding pipe is installed between housing lower end and the piston seat, the longitudinal elasticity performance is good, consistent with the flexible direction of retaining spring, the length the during elongation of threaded folding pipe is greater than the length of piston seat to chevron part bottom.
Compared with prior art, the chevron part is installed on the piston rod among the present invention, can be alleviated the piston rod axis that occurs in the driving process and depart from and friction problem; The elasitic layer of buffer layer and interior edge can effectively reduce the leakage problems of fluid in the piston movement and chevron part to the impact of bottom, improves using effect and increases the service life; The fluid adsorption piece can adsorb by the fluid of seepage when using, and does not pollute miscellaneous part.
