The work process of the present invention
The elimination of horizontal hunting: vehicle has been rolled by stone, causes the swing of vehicle, and the liquid in the horizontal piston cylinder on the left side exists
After being stretched, after right diversion column 28, right outlet 29 suck the liquid of the rotation pump housing 10-1 of upper part, this
Sample allows for upper cavity 10-1 cavity volume and reduces, and lower chamber 10-2 volume increases, owing to whole rotation pump piston internal layer 8 is solid
Fixed motionless, piston30 do not rotate, and thus force piston9 are rotated up, and rotate pump piston outer layer 3 by wheel one
Side is provided with sealing baffle 45, and the shaft core position of sealing baffle 45 is provided with wheel hub 33, is provided with wheel outside electric vehicle hub 33

Rotor 36, this wheel hub motor rotor is embedded in hub motor shell, and hub motor shell is vehicle wheel spoke 37, wheel spoke
37 wheel rims 38 of bar are fixedly connected on hub motor shell, the most whole tire superposition one again on the basis of original motion
Individual rotation, rotates an angle so that the linear velocity of tire outer rim increases.So, the movement velocity of vehicle does not change, and changes
Become is the shaft core position of tire.I.e. tire axis can occur swing, but this swing does not results in the pendulum of whole car
Dynamic, tire axis occurred level swings when, the border line speed of tire changes, and thus eliminates the level punching of vehicle
Amount.
After vehicle has rolled stone, entering into the flat compliant motion stage, horizontal hunting passes through horizontal force back-moving spring
31 reset, and on the other hand the motion of horizontal piston 20 makes liquid produce flowing, material is thus formed damped motion, so
Weaken swing the most greatly, it is often more important that the variable motion at wheel edge is that elimination of level swings most important factor.
The elimination of vertical direction vibrations: when automobile is travelling forward when, and wheel is rolled by stone, and wheel can upwards be jumped
Dynamic, thus make rotation pump piston outer layer 3 follow and upwards beat, the liquid in then lower piston 17 extrudes lower cylinder body 16, liquid
Body enters in lower chamber 10-2；On the other hand, the liquid in upper piston 1 aspirates upper cylinder body 2 so that the liquid in upper cavity 10-2
Body reduces, due to piston9 is fixed, thus forces piston30 rotate clockwise, and so may result in central shaft 19
Position do not change, but felly is being lifted up, and accelerates to rotate simultaneously, the most dynamically eliminates Vertical Square
Vibration the most upwards, fast when vehicle tyre rolls at the end of, at diversion column back-moving spring 7 and the work of piston boit back-moving spring 11
Under with, vertical piston 13 resets, and rotates pump piston outer layer 3 and reversely rotates counterclockwise, and central shaft 19 is returned to rotate pump work simultaneously
The shaft core position of layer 3 annulus, the most dynamically eliminates vibrations downward in vertical direction beyond the Great Wall.
The calibration of initial perpendicular direction force: the when of changing due to the weight of vehicle self, rotates pump piston outer layer 3
With the shaft core position rotated between pump piston internal layer 8 can change, in the ideal situation, rotate pump piston outer layer 3 annulus and
The axle center rotating pump piston internal layer 8 annulus is overlapping, when the weight of vehicle body becomes big, rotates the shaft core position of pump piston outer layer 3
Can be higher than the shaft core position of rotation pump piston internal layer 8, equally when tare diminishes, rotate the position, axle center of pump piston outer layer 3
Putting can be less than the shaft core position rotating pump piston internal layer 8.After opening electric switch, Photostimulable luminescence probe 23 emits beam, corresponding
Under photosensitive receiving transducer 24, the photosensitive receiving transducer in center 25 and upper photosensitive receiving transducer 26 will receive signal, it is judged that out
Rotate piston pump internal layer 3 relative to the shaft core position rotating piston pump outer layer 8, start high-pressure oil pump device 42 afterwards, if rotating
The shaft core position of piston pump internal layer 3 is less than the shaft core position of rotation piston pump outer layer 8, and hydraulic oil is passed through high pressure by high-pressure oil pump 42
Oil pipe 44 is injected in plunger shaft 14, owing to the plunger shaft 14 of the left and right sides is by carrying out UNICOM, therefore high pressure liquid communicating pipe 15
After force feed is injected, just improving the position of vertical piston 13, overall lifting rotates the position of piston pump internal layer 3, when photosensitive
Luminescent probe 23 emits beam after being received by the photosensitive receiving transducer in center 25, shows that rotating piston pump internal layer 3 lives with rotating
The axis coinciding of plug pump outer layer 8, calibrates complete, at this time sends enabled instruction, and electric motor car brings into operation.
The operation principle of the present invention:
After the tire of electric motor car is impacted, see Fig. 4, in rotational direction have a tangential force and power vertically upward, this meeting
Cause tire in rotational direction to accelerate to rotate an angle, and whole tire is moved upward；The moment that impact disappears, upwards
The tire beated lands, and causes downward one to impact.Fluid power returns the vertical movement of wheel damping disc and coordinates the additional of tire outer rim
Rotation can realize the vibration damping of vertical direction.And the vibration attenuation mechanism of level longitudinal direction is as shown in Figure 2: the linear velocity of tire determines vehicle
Movement velocity, such as rotate n circle tire speed be, after being impacted, if the invariant position in axle center to be kept, then turn
The tire speed of dynamic n circle is, because of, so having, thus after being hit, need in rotational direction accelerate to rotate an angle, improving wheel
Tire linear velocity just can be dissolved tyre rim and be impacted.For vertical vibration, after wheel is impacted, if axle center can be kept
Invariant position, then just can eliminate the vibration of vertical direction, in order to reach this target, is necessary for additionally increasing tire outer rim
Linear velocity.Wheel of the present invention, after being impacted, can meet above-mentioned 2 requirements simultaneously.Can be automatically according to the size of impulsive force
Regulation rotational angle and axis wheel position, after being impacted, keep vehicle's center of gravity horizontal level constant, dissolved transient state punching
Hit.After impact disappears, under the effect of equilibrant spring, the axle center of tire moves down, it is to avoid tire lands, and causes downwards
An impact.The good characteristic that had of invention so that the effectiveness in vibration suppression of tire greatly improves, so disappears decreasing kinetic energy
While consumption, improve the comfortableness of automobile.
Beneficial effects of the present invention
For electric motor car, the used wheel hub motor of electric motor car, direct drive of wheel advances, and tire is outside wheel hub motor
On shell, after transient impact, tire axis position change, meanwhile, the superposition again on the basis of original motion of whole tire
One rotation, rotates an angle so that the linear velocity of tire outer rim increases, and so, the movement velocity of vehicle's center of gravity is not
Changing, change is the shaft core position of tire, thus the present invention has the linear speed that can dynamically regulate tire according to the size of amplitude
Degree, keeps vehicle motor process position of centre of gravity constant, has dissolved the impact that transient state horizontally and vertically goes up, can effectively drop
The deformation quantity of low wheel structure, reduces resistance to rolling, wheel energy consumption is greatly reduced；On the other hand, directly realize indulging on wheel
To with vertically to vibration-damping function, reduce the complexity of vehicle structure, reduce cost.
