Abstract
The utility model relates to a damping device for a vehicle, which comprises a damper main body and a protection cover covered on the damper main body, wherein a rolling support structure is arranged between a cylinder of the damper main body and an inner wall of the protection cover; the rolling support structure comprises a plurality of longitudinal sliding slots arranged on the cylinder and ball bearings arranged in the sliding slots; and the diameter of the ball bearings is more than the depth of the sliding slots. The structure can be used for efficiently preventing the contact friction between the protection cover and the damper main body in up and down relative motion, so as to improve the working condition of the damper, lower the noise pollution and prolong the service life of the damper.
Description
Technical field
The utility model relates to a kind of vehicle shock-absorbing device.
Background technique
The external safety cover that generally is provided with of the basis of existing vibration damper, safety cover can prevent that silt stone, dust, sewage etc. from directly closely going into to seal the vibration damper working area, and the protection seal element preserves from, and protection vibration damper body is not subjected to mechanical collision.But supporting member is not set generally between the safety cover of vehicular shock absorber and the body.Because safety cover is long and less with the gap of vibration damper body, it is quite harmful can occurring scraping phenomenon and such scraping between vibration damper body and the safety cover, and issuable consequence has: send mechanical noise; form frictional heat; influence operating mode, injuring part shortens the life-span.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of vehicle shock-absorbing device, and it can make safety cover and the vibration damper body can the generating plane contact friction when doing relative movement up and down, improves the vibration damper operating mode, reduces noise, prolongs vibration damper working life.
The technological scheme that realizes the utility model purpose is as follows:
A kind of vehicle shock-absorbing device; comprise the vibration damper body and be enclosed within safety cover on this damping body; be provided with the rolling supporting structure between the cylinder barrel of vibration damper body and the safety cover inwall; described rolling supporting structure comprises a plurality of vertical slide slot that is opened on the cylinder barrel; and be arranged on ball in the slide slot; the diameter of described ball is greater than the degree of depth of slide slot, and ball slides between safety cover inwall, slide slot bottom land.
Offer three vertical slide slots on the described cylinder barrel, three vertical slide slots are distributed on the cylinder barrel.
Offer four vertical slide slots on the described cylinder barrel, four vertical slide slots are distributed on the cylinder barrel.
Described slide slot is the circular arc slide slot, and ball can roll in slide slot very swimmingly like this.
Adopt such scheme; be provided with after the rolling supporting structure on the cylinder barrel of vibration damper body and between the safety cover inwall; this structure can effectively prevent the face contact friction that safety cover and vibration damper body are taken place when doing relative movement up and down; and then improved the vibration damper operating mode; reduce noise pollution, prolonged the vibration damper life-span.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1 is the vibration damper body, and 2 is safety cover, and 3 is vertical slide slot, and 4 is ball, and 5 is piston rod, and 6 is cylinder barrel.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
As shown in Figure 1; a kind of vehicle shock-absorbing device; comprise vibration damper body 1 and be enclosed within safety cover 2 on this damping body; the piston rod 5 of vibration damper body passes the outside that the safety cover end reaches safety cover; be provided with the rolling supporting structure between the cylinder barrel 6 of vibration damper body and the safety cover inwall; the rolling supporting structure comprises four vertical slide slots 3 that are opened on the cylinder barrel; four vertical slide slots are distributed on the cylinder barrel; and be arranged on ball 4 in the slide slot; ball slides between safety cover inwall, slide slot bottom land, and the diameter of ball is greater than the degree of depth of slide slot.Slide slot is the circular arc slide slot, using an end after the time, can also add Lubricants in slide slot and improve lubricity, and ball is slided in slide slot swimmingly.
