Background technology
Concussion when damper is mainly used to suppress to rebound after spring shock-absorbing and impact from road surface.By not level road
During face, although shock-absorbing spring can filter the vibrations on road surface, spring itself also has a reciprocating motion, and damper be exactly for
Suppress this spring jump.Damper is too soft, vehicle body will vertical bounce, damper can bring about very much too big resistance firmly,
Hinder spring normal work.
Traditional damper mainly includes cylinder body, and piston is provided with cylinder body, and piston rod is fixed with piston, is gone back on piston
Be provided with damping hole, both ends of the spring is separately fixed on piston rod and cylinder body, when automobile is given a shock, spring be pressurized or by
Draw, piston rod is also with up and down motion, and piston is slowed down the jump of spring by larger resistance during motion.The resistance that piston is subject to
Power is determined that under the prior art, after damping hole is once be molded, aperture is unalterable by damping hole.This is also resulted in
The damping of existing damper can not be adjusted.
And vehicle, when different road travelings, required damping differs：In stable road traveling,
Need to damp a little bit smaller, avoid influenceing the normal work of spring；At the road surface jolted, then need to damp larger, avoid
Vehicle vertical bounce is caused because spring resume speed is too fast.Therefore, in the market needs a kind of pressure regulation damper, being capable of basis
The difference on road surface, regulation damping so that user obtains good comfortable seating and felt.
Utility model content
The utility model is directed to deficiency of the prior art, there is provided a kind of pressure regulation damper, can be according to the reality of user
Border demand regulation damping, so as to suitable for various road environments, provide comfortable take for user and feel.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：A kind of pressure regulation damping
Device, including cylinder body, slide in the cylinder body and be provided with first piston, second piston and the third piston, the first piston by trace and
The second piston is connected, and the first piston and the third piston are respectively arranged with first damping hole and the third damping hole, on the second piston
It is provided with second through hole, on the same line, third piston is provided with third in the axle center of the second passage and third damping hole
Passage, the second piston are provided with some guide spiro rods, and the guide spiro rod is through third piston and in end set
Limited location termination, is threaded with lock-nut on the guide spiro rod, and the lock-nut limits third piston and described
Maximum spacing between second piston, the lock-nut periphery are provided with driven gear, and third piston is connected with piston rod,
Sleeve is arranged with outside the piston rod, the sleeve bottom end is provided with driving gear, the driving gear and the driven gear
Cooperating is engaged, the sleeve top is provided with rotation section.
Preferably, four cavitys, respectively the first chamber are divided into by the first piston, second piston and the third piston in the cylinder body
Body, the second cavity, the 3rd cavity and the 4th cavity.
Preferably, the rotation section is provided with belt wheel.
Preferably, the rotation section is provided with rotating disk, and the rotating disk radiation is provided with several handles.
The utility model provides a kind of technical scheme of pressure regulation damper, can be adjusted and hindered according to the actual demand of user
Buddhist nun, so as to suitable for various road environments, provide comfortable take for user and feel.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：It is as shown in figure 1, a kind of
Pressure regulation damper, including cylinder body 1, interior slide of the cylinder body 1 are provided with first piston 2, the piston 4 of second piston 3 and third, the first piston
2 are connected by trace 22 with the second piston 3, and the piston 4 of first piston 2 and third is respectively arranged with first damping hole 23 and third
Damping hole 42, is provided with second through hole 31 on the second piston 3, and the axle center of the second passage 31 and third damping hole 42 is same
On one straight line, third piston 4 is provided with the third passage 41, and the second piston 3 is provided with some guide spiro rods 5, the guiding
Screw rod 5 through third piston 4 and is threaded with locking on end set limited location termination 51, the guide spiro rod 5
Nut 6, the lock-nut 6 limit the maximum spacing between third piston 4 and the second piston 3, outside the lock-nut 6
Disc is provided with driven gear, and third piston 4 is connected with piston rod 43, sleeve 7, the set are arranged with outside the piston rod 43
7 bottoms of cylinder are provided with driving gear 71, and the driving gear 71 and driven gear engagement cooperating, the sleeve 7 push up
End is provided with rotation section 72.
Divided in the cylinder body 1 by the first piston 2, the piston 4 of second piston 3 and third for four cavitys, respectively the first cavity
11st, the second cavity 12, the 3rd cavity 13 and the 4th cavity 14.
The rotation section 72 is provided with belt wheel.The sleeve 7 of the present apparatus can be rotated by automated manner to control, by rotation section
The belt wheel V belt translation set on 72 is connected with motor, by motor just can drive sleeve 7 have rotated.
The rotation section 72 is provided with rotating disk, and the rotating disk radiation is provided with several handles.The sleeve 7 of the present apparatus can lead to
Cross manual mode and rotated to control, as long as rotating rotation section 72 sets 1 rotating disk, it becomes possible to which band moving sleeve 7 have rotated.
The present apparatus, when vehicle is exercised on stable road surface, driving gear 71 is not tightened so that the He of second piston 3
Third piston, 4 segment distance disconnected from each other.Space is so produced between the two, and this space is exactly the 3rd cavity 13, then is led in second
In the presence of the passage 41 of stomata 31 and third, the second cavity 12, the 3rd cavity 13 and the 4th cavity 14 have just been connected.Now, only
There is first piston 2 to play damping action, damping force is simultaneously little, avoids damper from hindering spring works.
When vehicle will exercise the road surface jolted, lock-nut is driven by the driving gear 71 on sleeve 7
6, so that the piston 4 of second piston 3 and third is adjacent to each other, both final patches are integral, so, can not produce sky between the two
Gap, the 3rd cavity 13 have not been existed, and the 4th cavity 14 is connected by the third damping hole 42 with the second cavity 12, the second cavity 12
Pass through the cavity 11 of first damping hole 23 and first again.Now the third piston 4 and first piston 2 produce damping action.In this way, damping force
It is big with regard to becoming, avoid spring from recovering too fast, so as to cause the bounce of vehicle.
The present apparatus is in this way, enable to user to be voluntarily adjusted according to the road conditions of reality and personal feeling, just
Just it is quick.And because regulation is that user is voluntarily adjusted, therefore be not in the situation generation of mistuning.
The scope of protection of the utility model includes but is not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Sharp claim is defined, and any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
The utility model provides a kind of technical scheme of pressure regulation damper, can be adjusted and hindered according to the actual demand of user
Buddhist nun, so as to suitable for various road environments, provide comfortable take for user and feel.
