Domain.
Background technique
Hydraulic shock-absorption is a kind of common damping modes of automotive field.In the output end and ontology point of automobile hydraulic shock-damping device
It is not mounted on vehicle body and wheel set, shock absorber piston is typically provided in automobile absorber, when automobile is in driving process
In when there is vertical tremor, piston moves back and forth in piston cylinder, valve block mechanism is provided in piston, therefore work as piston reciprocating
When movement, the hydraulic oil positioned at piston two sides can back and forth flow through work by the flowing hole on piston with the direction opposite with piston
Plug, to play cushioning effect.
In the prior art, the movement speed of piston is directly proportional to the vibration amplitude degree of automobile in automobile absorber, i.e.,
The vibration amplitude of automobile is bigger, and the speed of reciprocating motion of the pistons is faster, and the speed for the piston that hydraulic oil flows through is also faster.However vapour
Vehicle will appear the case where vibration mutation in the process of moving, as wheel touches biggish barrier or wheel precepitates into hole
In, when above situation occurs, become larger rapidly in the spacing short time between vehicle body and wheel set, therefore in this case
Piston still carries out damping adjusting according to the shock conditions of vehicle body, then is easy to will appear the spacing between wheel set and vehicle body
Suddenly change and so that automobile is damaged, in the prior art, by electric-control system may be implemented the pressure short time variation very
The effect that the flow of hydraulic oil is controlled when big, but electric-control system price is costly and control process is complex.
Therefore designing one kind, flow will slowly increase after pressure increases to certain value or flow remains unchanged, the vapour even reduced
Vehicle hydraulic damper becomes current urgent problem to be solved.

Specific embodiment
Fig. 1 is the most preferred embodiment of the utility model, and 1 ~ 4 pair of the utility model is described further with reference to the accompanying drawing.
Embodiment 1:
As shown in Figure 1, single valve piece guiding axis throttle type Bidirectional damping mechanism, the damping mechanism ontology including circular tube shaped
5, go out to be respectively arranged with an end cap 3 in the both ends open of damping mechanism ontology 5, several flowing holes 1 are offered on end cap 3,
In this single valve piece guiding axis throttle type Bidirectional damping mechanism, flowing hole 1 is uniformly provided with end cap 3 and damping mechanism ontology
5 junction.
It is provided with a piece of valve block 6 at the lumen centers of damping mechanism ontology 5, is respectively arranged with one in the two sides of valve block 6
Tower spring 4, two sides tower spring 4 are located at corresponding survey between end cap 3 and valve block 6.It is also set up in the inner cavity of damping mechanism ontology 5
There is a guiding axis 7 axially penetrated through, the tower spring 4 of valve block 6 and its two sides is sleeved on the outer ring of guiding axis 7 simultaneously.The end cap 3 at both ends
Inner surface on be also respectively provided with spring limiting part 2, prevent tower spring 4 from deviating during contraction or release, spring
Monoblock type or segmented can be used in locating part 2.
Any end of 7 self-damping mechanism body 5 of guiding axis, which is drawn, is used as piston rod 8, or in the outer of damping mechanism ontology 5
End setting and the coaxially connected piston rod 8 of guiding axis 7, piston rod 8 drive damping mechanism ontology 5 to move, and are formed and are based on single valve piece
The hydraulic shock-absorption piston of guiding axis throttle type Bidirectional damping mechanism.
In this single valve piece guiding axis throttle type Bidirectional damping mechanism, valve block 6 is preferably designed for annular shape, guiding axis
7 section same design is circle, and the outer diameter (perimeter) of guiding axis 7 uniformly becomes larger from intermediate to both ends.Valve block 6 and guiding axis 7
Between interval form the circulation passage that hydraulic oil flows in or out damping mechanism ontology 5, (perimeter is most at 7 largest outside diameter of guiding axis
General goal) diameter be less than the diameter (interior circumference) of 6 inner hole of valve block will not be by liquid therefore when valve block 6 is moved at end cap 3
The circulation passage of pressure oil blocks completely.When valve block 6 along guiding axis 7 to when moving at two sides end cap 3, the circulation area of circulation passage
It is gradually reduced, to realize the throttling action to hydraulic oil.

Then body 5 flows after being spaced the circulation passage of formation between valve block 6 and guiding axis 7 from the flowing hole 1 on other end end cap 3
Out.
When the impact force of hydraulic oil is larger, valve block 6 can overcome under the promotion of hydraulic oil the elastic force of corresponding column spring 4 and be sent out
Raw movement, since 4 even thickness of tower spring changes, the elastic force of tower spring 4 is gradually changed, therefore the contraction state of tower spring 4 can be with
It is gradually tapered up with the variation of hydraulic fluid pressure, therefore valve block 6 in the process of moving can be along guiding axis 7 gradually to damping mechanism
It is moved on the outside of ontology 5, since the outer diameter of guiding axis 7 is gradually increased, so that the circulation area of hydraulic oil reduces, slows down damping machine
The degree of displacement of structure ontology 5, if hydraulic oil is excessive to the extruding force of valve block 6, valve block 6 can be moved to damping mechanism ontology 5
Inner terminal, the circulation area of hydraulic oil is minimized, restriction effect is realized.When the pressure of hydraulic oil is gradually reduced,
Valve block 6 can gradually reset under the action of tower spring 4.
