Description
Technical field
The present invention relates to shock absorber for vehicle field, and in particular to vehicle shock absorber compression valve.
Background technology
The damping hole of traditional compression valve of shock absorber midsole valve body has fixed quantity and external diameter, its valve line face step difference
It is fixed.This valve architecture is disadvantageous in that：To meet different damping force requirements, it is necessary to plurality of specifications --- no
Same damping hole circulation area (i.e. different damping hole numbers and external diameter) and the bottom valve body of valve line step difference, that is, need out a variety of
The bottom valve mould of specification, part category is more, and part management is more not convenient, especially the higher part of similarity degree.Die sinking
Cost and management cost are therefore high.
The content of the invention
Present invention aims at vehicle shock absorber compression valve is provided, while the specification of bottom valve body is reduced, resistance is realized
Buddhist nun hole circulation area and valve line face step difference (i.e. valve block combination preloads) are adjustable.
The present invention is achieved through the following technical solutions：
Vehicle shock absorber compression valve, including screw rod and bottom valve body, circumferential along the bottom valve body open on its end face
There are multiple damping holes, groove is provided with the middle part of the bottom valve body end face, axis of the screw rod along the bottom valve body sequentially passes through institute
State groove and bottom valve body body, damping hole are distributed in the groove, current limliting valve block, and current limliting valve block are arranged with screw rod
It is fixed on by the nut of T-shaped in groove, the current limliting valve block carries out local complexity to the damping hole；Along the axle of the screw rod
Throttle valve plate, valve block component and spacing pad are disposed with the outer circle wall of screw rod to towards the direction away from groove, and
The throttle valve plate, valve block component and spacing pad are fixed on bottom valve body end face by nut, circumferential at it along the groove
Inner peripheral wall is provided with height and groove groove depth identical annular projection, and the maximum of the throttle valve plate and the valve block component is outer
Footpath is identical, and the external diameter of the throttle valve plate is more than the external diameter of the current limliting valve block；Also nut vertical section is set in including setting
On flow- through valve plate and spring, spring be placed between flow- through valve plate and nut horizontal segment, be provided with the flow- through valve plate multiple
The through hole corresponding with damping hole, is provided with the runner through its body, and runner one end open on bottom valve body, runner it is another
End is sealed by flow- through valve plate, and the opening for damping hole and flow passage is provided with the throttle valve plate.
For in the prior art, the compression valve of conventional damper is when meeting the requirement of different damping power, it is necessary to open up a variety of
The bottom valve mould of specification, and then cause production cost drastically to increase, while management is not utilized；On the other hand, applicant is to existing
Compression valve is necessarily improved, i.e., a circular groove is set on the end face of bottom valve body, and the bottom land of groove is one flat
Face, multiple damping holes are distributed in the range of the plane covers, and screw rod is realized and bottom valve body behind the middle part of the plane
Cooperate, and applicant is arranged current limliting valve block on screw rod, and the external diametrical extent of the current limliting valve block existsArriveIn the range of,
WhereinTwice for damping hole with the maximum distance values of bottom valve body axis, andFor the minimum of damping hole and bottom valve body axis
Twice of distance values, i.e., according to specific design requirement,ArriveIn the range of current limliting valve block can be to damping hole carry out office
Portion covers, and to form the damping oil liquid stream circulation passage of different area, and then causes bottom valve body to produce different high speed damping forces；
Further, the design thickness of current limliting valve block can ensure that bottom valve body restores and will not be deformed in compression travel, in bottom valve
Body forms valve line plane backwards to the plane where the end face of groove, and valve block component and throttle valve plate are covered in the valve line plane
On opposite direction, and the opening for being used for connecting runner and damping hole is provided with throttle valve plate, i.e., is compressed in shock absorber
Fluid enters in groove by the through hole in flow- through valve plate during stroke, is then moved in damping hole, because current limliting valve block is to resistance
What Buddhist nun hole was carried out is local complexity, i.e., fluid can enter in damping hole out of groove, finally by the opening on throttle valve plate
Moved to shock absorber bottom, and according to being actually needed, the external diameter of current limliting valve block is replaceable so that current limliting valve block is formed to damping hole
Different area coverages, i.e. bottom valve body can produce different high speed damping forces in recuperation；And when shock absorber is carried out
During stretching travel, fluid enters along runner, then the non-through bore portion of flow- through valve plate is impacted so that flow- through valve plate horizontal sliding
Open, that is, realize movement of the fluid from shock absorber bottom to its top.
Wherein, throttle valve plate is identical with the external diameter of the valve block component, and the external diameter of the throttle valve plate is more than the limit
Flow the external diameter of valve block so that opening on throttle valve plate unique circulation path between runner and groove, to ensure bottom valve body
Different Low speed damping forces can be produced.And valve block component is made up of multiple stacked valve blocks, the thickness and outer diameter ruler of valve block
The very little occupation mode according to shock absorber determines, and ensures the external diameter phase of the external diameter and maximum valve block in valve block component of throttle valve plate
Together.
Also include packing ring I, the packing ring I is set on screw rod and positioned at backwards to the side end face of bottom valve body one of groove and throttling
Between valve block.Step difference H is designed between the boss plane and valve line plane of bottom valve body, the thickness of packing ring I is less than H, when to nut
When applying certain screw-down torque, valve block component can be formed it is different preload, to produce different middle Low speed damping forces, for not shadow
The normal circulation of damping hole inner fluid is rung, the external diameter of packing ring I is equal to or less than
Also include the packing ring II being set on the screw rod outer circle wall, the packing ring II is located at valve block component and spacing pad
Between.Further, packing ring II is set between valve block component and spacing pad, to provide deformation fulcrum for valve block component with reality
The valve opening of existing valve block component.
The spring is taper spring.Preferably, taper spring is the helical spring of internal diameter gradual change, i.e., it is big including one
End and a small end, the big end of taper spring and the upper surface of flow- through valve plate during use, and the level of its small end and nut
The contact of section lower surface, can not only form reliable positioning, moreover it is possible to shock absorber is allowed when stretching travel to compression travel commutates
Flow- through valve plate resets rapidly closure, to form effective oil circuit.
The present invention compared with prior art, has the following advantages and advantages：
