Abstract
The utility model discloses a kind of damper hydraulic damping device, comprise piston rod, guider assembly that piston rod top is located in activity and be fixed at the rebuilt valve assembly of piston rod bottom, it is characterized in that: the bottom of guider assembly is fixed with buffering cylinder sleeve, the top of rebuilt valve assembly is fixed with buffer body, cushion dashpot cover has endoporus can be held buffer body and free in and out, and leaves gap between the endoporus of buffering cylinder sleeve and the cylindrical of buffer body.The utility model compares traditional shock absorber can have better buffer function when maximum tension length, effectively improves vehicle driving comfort.<b/>
Description
Technical field
The utility model relates to the vibration damper applied in automobile suspension system, particularly the damping device of vibration damper when maximum tension length.
Background technique
In the suspension system inside of most of automobile, vibration damper is housed, the vibration damper of automobile, also referred to as " suspension ", is made up of jointly spring and vibration damper.Vibration damper operationally can be in continuously compression and drawing process, when automobile running is in extreme road conditions, occur that stretching travel is excessive possibly, piston upper-end surface is caused to contact with guider lower end surface is improper, affect safety reliability during vibration damper work, also can reduce the working life of vibration damper simultaneously, the method adopted at present is that sheathed buffering blob of viscose cushions on the piston rod, but buffer function is not ideal, affects vehicle driving comfort.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides one and compares traditional shock absorber and can have better buffer function when maximum tension length, effectively improves the damper hydraulic damping device of vehicle driving comfort.
The utility model takes following technological scheme:
Damper hydraulic damping device, comprise piston rod, guider assembly that piston rod top is located in activity and be fixed at the rebuilt valve assembly of piston rod bottom, it is characterized in that: the bottom of guider assembly is fixed with buffering cylinder sleeve, the top of rebuilt valve assembly is fixed with buffer body, cushion dashpot cover has endoporus can be held buffer body and free in and out, and leaves gap between the endoporus of buffering cylinder sleeve and the cylindrical of buffer body.
The guide pad cylindrical that described cushion dashpot is enclosed within guider assembly is fixedly sleeved, and described buffer body is connected and fixed at piston rod cylindrical by jump ring.
After adopting technique scheme, when the piston rod of vibration damper moves toward maximum tension direction, buffer body can enter in buffering cylinder sleeve, small gap is left owing to cushioning between the endoporus of cylinder sleeve and the cylindrical of buffer body, so when piston rod continues toward the motion of maximum tension direction, shock absorber fluid force feed in buffering cylinder sleeve will flow out outward from micro gap, produce the pressure loss, thus generation damping force, play hydraulic cushion effect, compare the mechanical impact buffering method of the buffering blob of viscose that tradition adopts, obviously better cushioning effect can be had, effective raising vehicle driving comfort.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
Drawings illustrate the technical solution of the utility model and embodiment, further describe each details and the working principle thereof of embodiment below more by reference to the accompanying drawings.
As shown in the figure, damper hydraulic damping device of the present utility model, comprise piston rod 5, activity is located at the guider assembly 1 on piston rod 5 top and is fixed at the rebuilt valve assembly 8 of piston rod 5 bottom, the bottom of guider assembly 1 is fixed with buffering cylinder sleeve 3, described buffering cylinder sleeve 3 is fixedly sleeved at guide pad 2 cylindrical of guider assembly, the top of rebuilt valve assembly 8 is fixed with buffer body 7, described buffer body 7 is connected and fixed at piston rod 5 cylindrical by jump ring 6, buffering cylinder sleeve 3 has endoporus 4 can be held buffer body 7 and free in and out, gap is left between the endoporus 4 of buffering cylinder sleeve 3 and the cylindrical of buffer body 7.
During utility model works, when the piston rod of vibration damper moves toward maximum tension direction, buffer body can enter in buffering cylinder sleeve, small gap is left owing to cushioning between the endoporus of cylinder sleeve and the cylindrical of buffer body, so when piston rod continues toward the motion of maximum tension direction, shock absorber fluid force feed in buffering cylinder sleeve will flow out outward from micro gap, produce the pressure loss, thus generation damping force, play hydraulic cushion effect, compare the mechanical impact buffering method of the buffering blob of viscose that tradition adopts, obviously better cushioning effect can be had, effective raising vehicle driving comfort.
