(i.e. a part of damping oil of epicoele 21 flows into cavity of resorption 22 by DF arrow instruction path in figure), it addition, storage
In oil cylinder 1, a part of damping oil by external valve body opening 734, exocoel 101 and compensates breach 722, and extruding is mended
(i.e. a part of damping oil of cavity of resorption 22 is by E in figure to flow into cavity of resorption 22 after repaying valve block 72 and bottom valve valve block 71
Arrow instruction path flows into oil storage cylinder 1), the F-V curve that this process is formed is the BC line segment in Fig. 8.Ginseng
Seeing Fig. 8, in contrast, traditional vibroshock, the F-V curve that its high-speed stretch process is formed is in Fig. 8
BD line segment, BC line segment relatively BD line segment is the most many as seen from the figure, and i.e. the vibroshock of the present embodiment is at a high speed
During stretching, damping force is more mild, and car load comfortableness is higher.
Vibroshock according to the above embodiment of the present invention, piston rod is provided with epicoele and the cavity of resorption of connection working chamber
Liquid flow hole, and, the lower ending opening of liquid flow hole open wide, upper end open is hidden by a card-type valve block, so,
When compressing high speed compression (speed is more than 0.1m/s), a part of damping oil enters from cavity of resorption by the way of conventional
Entering epicoele, another part damping oil by the liquid flow hole in piston rod by cavity of resorption, is pushed open card-type valve block and is entered
Chamber, some damping oil is flowed out in oil storage cylinder by bottom valve assembly by cavity of resorption, so can slow down work
Damping force during plug high speed compression so that during high speed piston compression, (road surface fluctuating quantity is bigger) has flat
Slow damping force, mild damping force during high speed compression is then conducive to riding comfort；It addition, piston component
Having main piston and auxiliary piston, when high speed piston stretches, a part of damping oil of epicoele is from the 3rd side breach
Place flows directly into cavity of resorption, a part of damping oil via the auxiliary flow through hole of auxiliary piston then from the 4th side breach
Place flows into cavity of resorption, another part damping oil extruding the 4th valve block, the 5th valve block and the 6th valve block deflection deformation stream
Entering to cavity of resorption, in oil storage cylinder, a part of damping oil flows into cavity of resorption by bottom valve assembly so that high speed piston stretches
Time also there is mild damping force.Thus, above-mentioned vibroshock, when high speed compression is with stretching, all can obtain
To mild damping force, above-mentioned vibroshock can take into account handling and the riding comfort of vehicle.
It addition, one embodiment of the invention additionally provides a kind of vehicle suspension, it includes above-mentioned vibroshock.
It addition, one embodiment of the invention additionally provides a kind of vehicle, it includes above-mentioned vibroshock.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Any amendment, equivalent and the improvement etc. made within bright spirit and principle, should be included in the present invention
Protection domain within.
