Abstract
The utility model discloses an improved damping device. The improved damping device comprises a damper shell, a piston seat, a second spring seat welded on the damper shell and a piston rod fixedly mounted on the piston seat, a movable stop plate is arranged between the upper end of the shell and a piston head, air damping holes are reserved on the movable stop plate, an air cavity is arranged above the movable stop plate, an elastic layer is inlaid in the damper shell, two sides of the piston head are matched with the elastic layer, an M-shaped piece is mounted on the piston rod, and two sides of the M-shaped piece are matched with the elastic layer. Since the M-shaped piece is mounted on the piston rod, the axis deflection and friction problems of the piston rod during travelling can be mitigated, and the oil leakage problem and impact of the M-shaped piece on the bottom during movement of the piston can be effectively weakened via a buffering layer and the inlaid elastic layer, so that usage effect is improved, and service life is prolonged.
Description
Technical field
The utility model relates to safety installation and makes the field, is specifically related to a kind of improved damping device on the Motor Vehicle.
Background technique
Along with the raising of quality of life, 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 cooperate, its wearing and tearing are bigger, and then cause oil liquid leakage, not only pollute miscellaneous part, even may bring life harm.In addition in the process of moving because 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, influence damping effect, under serious situation, even damping hole can be stopped up, and then damping effect can't be played.
Summary of the invention
The utility model provides a kind of new improved damping device at the deficiencies in the prior art part.
The scheme that the utility model 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 has the slope, the fluid adsorption piece is installed in the joint of piston rod and piston seat, as sponge, the material of buffer layer is foam, rubber or sponge, high elasticity screw thread collapsible tubing 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 screw thread collapsible tubing 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 in the utility model, 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 motion 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.
