Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
Referring to Fig.1~Fig. 3, the present embodiment provides a kind of spring dampers, comprising: helical spring 1 and damper 2；
The spring intracavity 10 that spring wire both ends are extended to along the hand of spiral is formed in the spring wire of helical spring 1；
Damper 2, including working cylinder 3, the piston 4 that is slidably located in plunger shaft 30 and connection with plunger shaft 30
Piston 4 and the guide rod 5 with guiding rod cavity 50, plunger shaft 30 are divided into the first chamber 31 and the second chamber 32, guide rod by piston 4
5, which are connected to piston 4, is located at outside the first chamber 31 of one end stretching of the first chamber 31, is oriented to rod cavity 50 or the second chamber 32 and the first chamber 31 connects
It is logical；
Spring intracavity 10 includes at least one active section 11 along the hand of spiral, is externally provided in active section 11 and is connected to spring wire
Damper 2, the length direction of guide rod 5 is parallel to the axial direction of helical spring 1, is oriented to rod cavity 50 and the second chamber 32 is respectively communicated with
Active section 11；
It is equipped with fluid flowablely in active section 11.
Compared with prior art, in the spring damper of the technical program, bullet is formed in the helix of helical spring 1
Damper 2 is integrated in helical spring 1 by spring inner cavity 10, and the flowable space of damper 2 has been expanded in spring from damper 2
In the relevant work section 11 of chamber 10, which increase the flowable spaces of damper 2.On the one hand, this is breached to damper 2 itself
The limitation that size requires, the damper 2 of smaller size can make spring damper have good buffer shock-absorbing effect, drop
Low production cost.Moreover, the size of damper 2 is smaller, damper 2 not will increase spring damper in the cloth of suspension system
Office's difficulty, the layout of spring damper are simpler.On the other hand, helical spring 1 can not only play the vibration from road surface
To buffer function, certain damping effect is also acted as, increases product utilization rate.Moreover, helical spring 1 and damper 2 are integrated
Together, compact-sized, degree of integration is high.
On the other hand, for being oriented to rod cavity 50 and be connected to the first chamber 31, the work of the spring cushion of the technical program
Principle is:
Referring to Fig.1 and referring to Fig. 4, when in wheels travel in uneven road surface and by impact from road surface, helical spring 1
It is compressed with buffering vibration, guide rod 5 and working cylinder 3 are by the pressure applied from spring wire, and pressure direction phase
Instead, so that guide rod 5 can carry the opposite working cylinder 3 of piston 4 and move along the axial of helical spring 1 into the second chamber 32, piston 4 exists
The fluid in the second chamber 32 can be squeezed when movement successively flows into the first chamber 31 through active section 11, guiding rod cavity 50；
Referring to Fig.1 and Fig. 5, when in wheels travel in uneven road surface and by impact from road surface, helical spring 1 is pressed
It rebounds and is stretched after contracting, so that guide rod 5 can carry piston 4 with respect to working cylinder 3 along the axial to the first chamber 31 of helical spring 1
Interior movement, piston 4 can squeeze the fluid in the first chamber 31 successively through guiding rod cavity 50, active section 11, inflow first during exercise
Chamber 31.
One, in the compression of helical spring 1 and stretching travel, fluid flows the deformation quantity for being able to suppress helical spring 1, this
It can reduce oscillation when rebounding after rebounding and stretch after helical spring 1 compressing, helical spring 1 avoided to occur acutely to vibrate and make
It is excessively rolled at automobile, keeps running car stationarity；The two, the mistake that fluid flows between guiding rod cavity 50 and the first chamber 31
Cheng Zhong falls the energy dissipation that vibration generates.Therefore, during fluid flows between guiding rod cavity 50 and the first chamber 31,
There is absorption to vibration, absorb the impact from road surface, there is vibration-damping function, mitigate and rushed suffered by body of a motor car
It hits, admirably ensures ride comfort.
In the present embodiment, referring to Fig. 3~Fig. 5, the several of connection guiding rod cavity 50 and the first chamber 31 are equipped in guide rod 5
Damping hole 51, damping hole 51 allow fluid to guiding rod cavity 50 and the first chamber 31 between circulate, fluid from guiding rod cavity
50 flow into damping holes 51 during or from the first chamber 31 flow into damping hole 51 during, area of passage reduces suddenly, fluid
Flows decrease, flow reduce, and damping hole 51 plays damping action, this can inhibit the deformation quantity of helical spring 1 (referring to Fig.1), and
And fluid falls the energy dissipation that vibration generates when flowing through damping hole 51.The sum of the area of passage of all damping holes 51 is smaller
When, fluid is better to the deformation inhibiting effect of helical spring 1, but fluid mobility weakens the dissipation of energy generated to vibration and subtracts
It is few；, whereas if when the sum of area of passage of all damping holes 51 is larger, fluid to the deformation inhibiting effect of helical spring 1 not
It is good, but fluid mobility enhances, and can more effectively dissipate the energy that vibration generates.It therefore, should according to specific needs rationally
The sum of the area of passage of all damping holes 51 is designed, such as changes the aperture of single damping hole 51 and/or the quantity of damping hole 51,
Meet simultaneously and inhibits 1 deformation of helical spring excessive and the demand of the energy of effective vibration generation that dissipates.
Other than opening up damping hole 51 in guide rod 5, as a kind of variation, connect it may also is that being equipped in piston
Several through-holes of logical second chamber and the first chamber.At this point, the second intracavitary fluid can via through holes stream in helical spring compression process
It is intracavitary to enter first；In helical spring drawing process, it is intracavitary that the first intracavitary fluid meeting via through holes flow into second.
Referring to Fig.1, spring intracavity 10 includes 3 active sections 11 along the hand of spiral, and spring wire has in each active section 11
Along the axially opposing first segment 111 and second segment 112 of helical spring 1, guide rod 5 connects first segment 111 and working cylinder 3 connects
Second segment 112, wherein connection type can be welding.This allows for damper 2 when being packed into helical spring 1, and guide rod 5 is wanted
Be parallel to the axial direction of helical spring 1, if by damper 2 be mounted on spring wire along helical spring 1 axially-spaced two section it
Between, the spring wire between this two sections can cause damper 2 to interfere and can not assemble.
In Fig. 1, each active section 11 is equipped with 1 damper 2, and as a kind of variation, each active section 11 can pacify
At least two dampers 2 are filled, can be specifically designed according to mounting location and damper 2 and buffer shock-absorbing effect to be achieved.
Further, for spring intracavity 10 along the quantity of the programmable active section 11 of the hand of spiral, not by the present embodiment
The limitation of technical solution may be designed as at least two, and particular number can be according to mounting location and buffer shock-absorbing effect to be achieved
It is designed.
Referring to Fig.1,4 isolating valve,s 6 being distributed along the hand of spiral, two neighboring isolating valve, 6 are equipped in spring intracavity 10
Between spring intracavity part as closure active section 11.At this point, fluid stream will not occur between two neighboring active section 11
Dynamic, in each active section 11, fluid circulates between active section 11 and damper therein 2, and each active section 11 is made
For a cycling element.In other embodiments, the quantity of isolating valve, 6 will be set according to the quantity of active section 11 to be formed
Meter, therefore the quantity of isolating valve, 6 is not limited to the present embodiment.
As a kind of variation, it may also is that spring intracavity includes along the hand of spiral through the spring wire referring to Fig. 6
