Frame vertical supporting bar 900 is be hinged with gear ring bracing ring 342, and rotational axis line and guide sleeve 310 are tangent and with guide sleeve 310
Axis is vertical.In other embodiments, automotive suspension 10 can be not liftable, then suspension vertical supporting bar 900 can be with
Supporting plate 615 directly with annular shape is connected, and circular supporting plate 615 is lower than the position of gear ring bracing ring 342, allows automobile to hang
The fixed position on vehicle body of frame 10 is lower, can increase the intensity of automotive suspension 10.The automotive suspension 10 of this structure and connection
Mode, the intensity of wheel hub and automotive suspension 10 can be increased.
Further, in order to not influence front-wheel steer, hub connection member 100 can include mutually rotating up and down two
Partly (axis parallel of rotational axis line and guide rod 200 overlaps), wherein upper part connects with the second fixed seat 614
Connect, lower part is used to be connected with the wheel hub of automobile.Further, two parts up and down of hub connection member 100 can pass through axle
Hold connection.
The present embodiment also provides a kind of automobile, and the automobile includes any of the above-described kind of automotive suspension 10, the wheel hub and vapour of automobile
The hub connection member 100 of suspension 10 is connected, and the vehicle frame of automobile is connected with the frame connecting piece 300 of automotive suspension 10.
The principle and effect of the present invention comprises at least：The automotive suspension 10 of the present invention is using the first buffer spring 400 and the
The mode that two buffer springs 500 plus hinge 610 connect realizes, the second buffer spring 500 can make wheel 20 moment forced compression the
One buffer spring 400, stress disappear when, the second buffer spring 500 come balance the first buffer spring 400 recovery power, hinge 610
For preventing circular runout of the wheel 20 along guide rod 200, and can allows uniform force between guide rod 200 and guide sleeve 310, no
As for abrasion.
The automobile of the present invention can make the tire of automobile straight up and down, no matter it is unloaded or heavily loaded when, vapour can be ensured
The center of rotation of the tire of car can make tyre tread face and ground Full connected along horizontal, stability and tire is grabbed when braking
Soil fertility is good.
In order to reduce run into vehicle traveling process jolt when, the road surface of out-of-flatness applies fore-and-aft direction to automotive suspension 10
Shearing force, further, the axial line of guide rod 200 and ground out of plumb, axial line and the ground of guide rod 200 have necessarily
Inclination angle.
Suspension independent-lifting realizes that displacement power passes through by the axial displacement of suspension fixed cover 330 and guide sleeve 310
Suspension lifting on suspension fixed cover 330 drives 343 (hydraulic motor or motor) driven gear rings to realize, each wheel
10 lifting can be controlled individually, can also be lifted simultaneously.Wheel 10 is lifted according to road conditions, completes the choosing of automobile chassis different height
Select, individually lift some wheel 10 by property and the comfortableness driven, during turn during realizing running car, make it more flat
Surely.
The preferred embodiment of the present invention is the foregoing is only, is not intended to limit the invention, for this area
For technical staff, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made is any
Modification, equivalent substitution, improvement etc., should be included in the scope of the protection.
