Specific embodiment

It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.

In the disclosure, in the absence of explanation to the contrary, the noun of locality used is as " upper and lower " usually with corresponding attached It is defined on the basis of the page of figure, " inside and outside " refers to the inner and outer of corresponding component profile.

As shown in Figures 1 to 4, present disclose provides a kind of vehicle shock absorber, which includes outside damper Cylinder 1, dust shroud 2, piston rod 3 and oil sealing, dust shroud 2 cover at the upper end of damper outer cylinder 1, and piston rod 3 is arranged in anti- Dust hood lid 2, oil sealing are arranged between the upper end of damper outer cylinder 1 and piston rod 3, are formed and are surrounded between dust shroud 2 and oil sealing The annular space 4 of piston rod 3 offers the ventilation hole in the outside of connection annular space 4 and dust shroud 2 on dust shroud 2 21.In this way, oil vapour can be discharged from annular space 4 through ventilation hole 21, so that oil vapour when piston rod 3 moves above and below It can be discharged before condensation, oil vapour is avoided to recycle between dust shroud 2 and damper outer cylinder 1, to avoid oil vapour It is condensed in the lower end of dust shroud 2 and pollutes damper outer cylinder 1.It solves the problems, such as that original damper outer cylinder 1 pollutes, can disappear Except customer's worry, client is promoted to the reliability of the vehicle shock absorber 10.

Wherein, dust shroud 2 can have any suitable structure.In one embodiment, such as Fig. 2 and Fig. 3 institute Showing, dust shroud 2 includes roof 22 and the side wall 23 extended downwardly from the surrounding of roof 22, and piston rod 3 is arranged in roof 22, Side wall 23 is set on damper outer cylinder 1, and ventilation hole 21 is provided on side wall 23.

Further, in order to which the oil vapour guaranteed in annular space 4 as far as possible can be completely exhausted out through ventilation hole 21, in this public affairs It opens in a kind of embodiment, as shown in figure 3, position of the ventilation hole 21 on side wall 23 is flushed with the upper end of damper outer cylinder 1, i.e., The bottom of annular space 4, which is arranged in, in ventilation hole 21 leads to oily steaming to avoid due to oil vapour rests in annular space 4 for a long time Vapour passes through between the side wall 23 of dust shroud 2 and the inner wall of damper outer cylinder 1, so as to effectively avoid oil vapour anti- The lower end of dust hood lid 2 condenses.

Further, as shown in Fig. 2, above-mentioned ventilation hole 21 can be multiple, and multiple ventilation holes 21 can circumferentially uniformly Arranged for interval is on the side wall 23 of dust shroud 2, to promote oil vapour expulsion efficiency.In addition, in addition to present embodiment is in ring The lower end setting ventilation hole 21 in shape space 4 in other embodiments, may be used also in order to further enhance oil vapour expulsion efficiency In addition ventilation hole is set at the middle part of annular space 4 and/or top, i.e., on the top and/or top of the side wall 23 of dust shroud 2 Ventilation hole is set on wall 22.

In the disclosure, oil vapour passes through between the side wall 23 and damper outer cylinder 1 of dust shroud 2 in order to prevent, such as Shown in Fig. 3, in a kind of embodiment of the disclosure, it can be arranged between the inner wall of side wall 23 and the outer wall of damper outer cylinder 1 close Packing 5, to guarantee the air-tightness between the inner wall of side wall 23 and the outer wall of damper outer cylinder 1.In addition, as shown in figure 4, at this In open another embodiment, it can also be not provided with gasket 5, and the inner wall of side wall 23 and the outer wall of damper outer cylinder 1 is tight Closely connected conjunction, to block oil vapour.

In addition, in the disclosure, as shown in Figure 1, vehicle shock absorber 10 further includes boot seal 6,6 sets of boot seal It is located on piston rod 3, the lower end of the side wall 23 of dust shroud 2 is formed with the flange 24 perpendicular to side wall 23, boot seal 6 Lower end is connected to the upper surface of flange 24.Wherein, the oil vapour being discharged from annular space 4 can from boot seal 6 with turn over The junction on side 24 is emitted into the external world.
