As shown in Figure 1, its whole installation diagram that a kind of automobile absorber provided by the invention is shown.It can from figure
Know, which includes inner cylinder body 1, restores part 2, compression piece 3 and outer cylinder body 4, wherein the outer cylinder body 4 has chamber,
The inner cylinder body 1 is sheathed in the chamber of the outer cylinder body 4.
The automobile absorber further includes piston rod 5, wherein the piston rod 5 is fixedly installed in the inner cylinder body 1.
The piston rod 5 has at least two end multi-diameter shafts, is the first multi-diameter shaft 51 and the second multi-diameter shaft 52 respectively, and first ladder
The outer diameter of axis 52 is less than the outer diameter of first multi-diameter shaft 51.As shown in Figure 1, the recovery part 2 is fixedly installed in the work
On stopper rod 5, specifically, the recovery part 2 is fixedly installed on the second multi-diameter shaft 52 of the piston rod 5.
The recovery part 2 includes a limit plate 21, a gasket 22, a flow- through valve plate 23, the one recovery packet of throttle valve plate 24, one
Glue piston 25, one restores valve block 26, one and restores adjustment gasket 27, a rebuilt valve 28, one recovery valve nut 29.It is wherein described encapsulated
Piston 25 includes a first assembly 251 and one second component 252, wherein the first assembly 251 of the encapsulation piston 25 and second
Component 252 is mutually permanently connected in together, and be mounted on it is described restore on 2, and the encapsulation piston 25 for restoring part 2 and the vapour
The inner wall palette of the inner cylinder body 1 of vehicle damper, so that described restore is sealed in the chamber that part 2 and the inner cylinder body 2 form
The oil liquid closed is not revealed.It is worth noting that, it includes in the chamber of the piston rod 5 that oil liquid, which is enclosed in,.
Specifically, the first assembly 251 of the encapsulation piston 25 include an ontology 2512 and one from the ontology 2512 to
The protrusion 2511 of upper extension, generally, the cross section of the protrusion 2511 of the first assembly 251 are the rectangles or just of rule
Square protruding, certainly, described raised 2511 are also possible to other shapes, such as triangle, zigzag etc..The encapsulation piston
25 the second component 252 includes a fitting portion 2522 and a seal face 2521, wherein the fitting portion 2522 is from the sealing
End face 2511 extends downwardly, and second component 252 is integrally formed.It is convex in the first assembly 251 of the encapsulation piston 25
The groove risen on 2511 and second component 252 is mutually embedded in together, so that the first assembly 251 and described the
Two components are fixedly connected on together.This mode being mutually embedded in together, so that the first assembly 251 of the encapsulation piston 25
It is not easy to loosen when the damper works with the second component 252, or even falls.
It is worth noting that, the seal face 2521 of the second component 252 of the encapsulation piston 25 and the damper is interior
The inner wall surface of cylinder body 1, which seals against each other, to be fitted in together, therefore, the seal face of the second component 252 of the encapsulation piston 25
2521 outer surface is an annular surface.When the recovery part 2 is installed in the inner cylinder body 1, and the damper is in work
When making state, the piston rod 5 is moved back and forth, due to the seal face of the second component 252 of the encapsulation piston 25
2521 and the damper 1 inner surface palette of inner cylinder body in together, thus be in the inner cylinder body 1 and the recovery part 2
Oil liquid in the chamber of composition is not easy to reveal, so that the damping ratio of the damper be kept to stablize.It does not work in the damper, and
When wanting the state of entrucking, due to it is described restore part 2 encapsulation piston 25 and the inner cylinder body 1 between palette, and exist compared with
The viscous force of big frictional force and oil liquid, so that the case where actively shrinking back and forth seldom occurs in the piston rod 5.
