The both ends of connector 63 are separately connected wheel, and the position of such 63 both ends wheel of connector is that reciprocity influences, and are also just formed
Rigid axle suspension, and the first elastic component 61 and the second elastic component 62 can play cushioning effect.
A kind of vehicle proposed by the present invention, using the suspension of above-mentioned adjustable bodywork height；It can be this only using one
The inclination angle of vehicle body only can only be adjusted using the vehicle of the suspension of an above-mentioned adjustable bodywork height, and vehicle body cannot be made integrally to rise
Drop；If applying the suspension of multiple above-mentioned adjustable bodywork heights, when the suspension synchronization action of multiple adjustable bodywork heights,
The integral elevating of vehicle body may be implemented.
In the present invention, the vehicle proposed adjusts vehicle body by the movement of the suspension of the adjustable bodywork height
Height；Specifically, when on the rugged road surface of traveling, the suspension of all adjustable bodywork heights is acted so that vehicle body
Integral raising avoids scraping of the chassis by road surface so that chassis is elevated；On the preferable road surface of road conditions when driving, own
The suspension of the adjustable bodywork height acts so that vehicle body entire lowering, to reduce resistance suffered in vehicle travel process
Power saves oil consumption；When vehicle driving up, close to the suspension movement of the adjustable bodywork height of vehicle front, so that the vehicle in front
The decline of height degree, close to the suspension movement of the adjustable bodywork height at vehicle body rear, so that the bodywork height at rear is raised, thus
The inclination angle for changing vehicle body, avoids vehicle from toppling backward, and when vehicle descending, the adjustable bodywork height of close vehicle front hangs
Frame movement, so that the bodywork height in front is raised, close to the suspension movement of the adjustable bodywork height at vehicle body rear, so that rear
Bodywork height decline, to change the inclination angle of vehicle body, vehicle is avoided to topple forward；Through above-mentioned analysis it is found that described in
The vehicle body of the suspension of adjustable bodywork height, is adapted to different road conditions.
Referring to Fig. 5, there are two the suspension of the adjustable bodywork height is set, the suspension of two adjustable bodywork heights
In cylinder be respectively the first cylinder 41 and the second cylinder 42；
It further include reversal valve and the first shut-off valve 71, the second shut-off valve 72 and third shut-off valve 73；
First cylinder 41 and the second cylinder 42 pass through two gas outlets of the first pipeline and the second pipeline and reversal valve respectively
Connection, the first shut-off valve 71 are set on second pipeline, and first pipeline and second pipeline are connected by third pipeline
Logical, the second shut-off valve 72 is set on the third pipeline, and the first pipeline is in the first pipeline and third line connection and reversal valve
Between be equipped with gas outlet, third shut-off valve 73 be set to the gas outlet on.
In the course of work, when needing vehicle integral elevating, the first shut-off valve 71 and third shut-off valve 73 is closed, institute is passed through
It states the first pipeline to supply to the first cylinder 41 and the second cylinder 42, increase simultaneously in two the first gas springs and two the second gas springs
Pressure, and then two the first linking arms 21 and two the second linking arms 22 rotate synchronously, and realize the outstanding of two adjustable bodywork heights
Frame synchronization action, and then realize the integral raising of vehicle body；It opens third shut-off valve 73 to be vented, vehicle body entire lowering；When needing to adjust
When the tilt angle of vehicle body, the second shut-off valve 72 and third shut-off valve 73 are closed, is supplied by the second pipeline to the second cylinder 42
The suspension of gas, the adjustable bodywork height connecting with the second cylinder 42 is raised, the adjustable car height connecting with the first cylinder 41
The suspension height of degree is constant, to change the inclination angle of vehicle body, to adapt to the road conditions of ascents and descents, opens 72 He of the second shut-off valve
Third shut-off valve 73, the exhaust of the second cylinder 42, vehicle body restore to reset condition.
Referring to Fig. 6, the suspension of the adjustable bodywork height is equipped with multiple, adjustable vehicle body described in each adjacent two
The suspension of height is that the air cavity of the first gas spring of the suspension of adjustable bodywork height described in one group, every group is interconnected,
The air cavity of the second gas spring of the suspension of the adjustable bodywork height is interconnected in every group；To have eight in the present embodiment
For the vehicle of wheel, vehicle front two is one group to suspension, and rear of vehicle two teams suspension is one group.
Referring to Fig. 7, when in every group two the first gas springs and two the second gas springs be interconnected respectively after, vehicle row
Wheel quilt if encountering the protrusion on road surface during sailing, when one of wheel reaches protrusion top, above protrusion
Protrusion is risen, and vehicle body is also risen, and forces the first gas spring and the compression of the second gas spring at the wheel position, the first gas spring
It is inside forced out the gas come to enter with the first gas spring in another suspension in group, the gas come is forced out in the second gas spring
Body enters with the second gas spring in another suspension in group, so that the wheel connecting with other suspensions moves down, in this way
Although vehicle body is risen, all wheels be still with ground to against, be unlikely to vehicle and be in vacant state, vehicle is avoided to incline
It covers；As long as generally speaking there is pair of wheels to be risen, wheel will be declined with another pair wheel of group with this, to keep all
Wheel and ground face contact, avoid vehicle from toppling.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
