Description
Technical field
The utility model relates to a kind of damped valve system of vibration damper, is specifically related to the simple damped valve system of a kind of structure.
Background technique
Automotive wheel shifts near vehicle body, vibration damper by compression time, now vibration damper inner carrier moves down.The volume reducing of piston lower chambers, oil pressure raises, and fluid is pushed circulation valve block open and flow to chamber above piston.Epicoele have been accounted for a part of space by piston rod, and the volume that thus epicoele increases is less than the volume that cavity of resorption reduces, so a part of fluid just pushes compression valve block open, flows back to oil storage cylinder.The damping force that the saving formation suspension of these valves to oil moves by compression.Vibration damper is at wheel away from vehicle body, and vibration damper Tensile, at this moment the piston of vibration damper moves up.Piston upper chamber oil pressure raises, and flowing valve is closed, and the fluid in epicoele is pushed open and upheld valve block inflow cavity of resorption.Due to the existence of piston rod, the fluid come from epicoele stream is not enough to be full of the volume that cavity of resorption increases, and instigator's cavity of resorption produces a degree of vacuum, and the fluid at this moment in oil storage cylinder is pushed open and compensated valve block and flow to cavity of resorption and supplement.Due to the throttling action of these valves, therefore play damping function to when being suspended in and doing stretching exercise.
Existing rebound valve adopts the rigidity of spring and Prestress design to be greater than compression valve, and under same pressure effect, rebound valve and accordingly normal open gap and channel cross-sectional area summation are less than compression valve and corresponding normal open gap passage sectional area summation.This damping force that extension stroke of vibration damper is produced is greater than the damping force of compression stroke, reaches the requirement of rapid damping.The feature of this valve system is that component are more, assembles more complicated to such an extent as to assembling speed is slow.Purchase cost is high.This valve system requires very high to shock absorber fluid and turbidity test in addition.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 to Figure 3, the damped valve system of a kind of vibration damper of the present utility model, comprise the rebound valve 17 being located at piston rod afterbody and the compression valve assembly 18 be positioned at bottom clutch release slave cylinder 19, described piston rod is positioned at clutch release slave cylinder 19, described rebound valve 17 comprises the piston 5 be connected with piston rod, cover flowing valve limiting board 1 is on the piston rod provided with successively above described piston 5, circulation valve block 3 and flow regulator pieces 4, be provided with successively below piston 5 and uphold valve block 6, rebound valve limiting board 8 and hexagon nut 9, described hexagon nut 9 is arranged on the afterbody of piston rod, flowing valve limiting board 1, circulation valve block 3, flow regulator pieces 4 and piston 5 were provided with oily through hole successively, uphold the below that valve block 6 is positioned at piston hole, described compression valve assembly 18 comprises support 11, compression valve seat 16, is positioned at the compression valve flow regulator pieces 15 above compression valve seat 16 and compresses valve block 14, described support 11 is positioned at the bottom of clutch release slave cylinder, compression valve 13 is provided with above described compression valve block 14, Compress Spring 12 is provided with above compression valve 13, Compress Spring 12 is positioned at the cavity that support 11 forms with compression valve 13, described compression valve 13 radial direction is provided with several excessively oily axial holes, compression valve 13 is provided with cylindrical groove in bottom, and compression valve seat 16, compression valve flow regulator pieces 15 and compression valve block 14 are provided with through hole.
In the utility model, be provided with some between described extension valve block 6 and rebound valve limiting board 8 and restore pad 7, restore the thickness 0.3mm of pad 7, be provided with the some pads 2 that circulate between flowing valve limiting board 1 and circulation valve block 3, the thickness of every sheet circulation pad 2 is 0.3mm; Described circulation valve block 3 thickness is 0.3mm; Be provided with locking nut 10 outside described hexagon nut 9, when after the extension valve block 6 selecting suitable quantity, tighten hexagon nut 9, and then tighten locking nut 10, prevent hexagon nut 9 from loosening, the Prestress design of valve block 6 is upheld in impact.
