The course of work of the present invention
The elimination of horizontal hunting：Vehicle has been rolled by stone, causes the swing of vehicle, the liquid in the horizontal piston cylinder on the left side
Body is after being stretched, after right diversion column 28, by the liquid for rotating pump housing 10-1 of the right suction of outlet 29 upper part
Body, the reduction of upper cavity 10-1 cavity volumes is so allowed for, the increase of lower chamber 10-2 volumes, pump piston internal layer is rotated due to whole
8 be fixed, piston30 do not rotate, and thus force piston 9It is rotated up, rotates pump piston outer layer 3 and lean on car
Wheel side is provided with sealing baffle 45, and the shaft core position of sealing baffle 45 is provided with wheel hub 33, and the outside of electric vehicle hub 33 is installed
There is wheel hub motor stator 35, so allow for wheel hub motor stator 35 and rotate, because the outside of wheel hub motor stator 35 is installed
Wheel hub motor rotor 36, the wheel hub motor rotor are embedded into hub motor shell, and hub motor shell is vehicle wheel spoke 37, car
Wheel spoke 37 is fixedly connected on wheel rim 38 on hub motor shell, and then whole tire is folded again on the basis moved originally
Add a rotation, rotate an angle so that the linear velocity increase of tire outer rim.So, the movement velocity of vehicle does not change
Become, change be tire shaft core position.I.e. swing can occur for tire axis, but this swing will not cause whole car
Swing, when tire axis occurred level is swung, the outer rim linear velocity of tire changes, thus eliminate vehicle water
Flat momentum.
After vehicle has rolled stone, the flat compliant motion stage is entered, horizontal hunting passes through horizontal force back-moving spring
31 are resetted, and the motion of another aspect horizontal piston 20 causes liquid to produce flowing, material is thus formed damped motion, so
Just greatly weaken swing, 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, wheel is rolled by stone, and wheel can jump upwards
It is dynamic, so allow for rotation pump piston outer layer 3 and follow upward bounce, then lower piston 17 extrudes the liquid in lower cylinder body 16, liquid
Body is entered in lower chamber 10-2；On the other hand, upper piston 1 aspirates the liquid in upper cylinder body 2 so that the liquid in upper cavity 10-2
Body is reduced, due to piston9 be fixed, thus forces piston30 rotate clockwise, and so may result in central shaft 19
Position change, but felly is being lifted up, while accelerates to rotate, and thus dynamically eliminates Vertical Square
Upward vibration, at the end of fast when wheel tire rolls, in diversion column back-moving spring 7 and the work of piston boit back-moving spring 11
Under, vertical piston 13 resets, and rotates pump piston outer layer 3 and reversely rotates counterclockwise, while central shaft 19 is returned to and rotates pump work
The shaft core position of the annulus of layer 3 beyond the Great Wall, thus dynamically eliminates vibrations downward in vertical direction.
The calibration of initial perpendicular direction force：When being changed due to the weight of vehicle itself, pump piston outer layer 3 is rotated
Can be changed the shaft core position rotated between pump piston internal layer 8, in the ideal situation, rotate the annulus of pump piston outer layer 3 and
The axle center for rotating the annulus of pump piston internal layer 8 is overlapping, when the weight of vehicle body becomes big, rotates the shaft core position of pump piston outer layer 3
The shaft core position for rotating pump piston internal layer 8 can be higher than, equally when car body weight change is small, rotate the axle center position of pump piston outer layer 3
The shaft core position for rotating pump piston internal layer 8 can be less than by putting.After opening electric switch, Photostimulable luminescence probe 23 emits beam, corresponding
Under photosensitive receiving transducer 24, the photosensitive receiving transducer 25 in center and upper photosensitive receiving transducer 26 will receive signal, judge
Piston pump internal layer 3 is rotated relative to the shaft core position for rotating piston pump outer layer 8, starts high-pressure oil pump device 42 afterwards, if rotating
Hydraulic oil is passed through high pressure by the shaft core position of piston pump internal layer 3 less than the shaft core position for rotating piston pump outer layer 8, high-pressure oil pump 42
Oil pipe 44 is injected into plunger shaft 14, because 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 injection, just improve the position of vertical piston 13, overall lifting rotates the position of piston pump internal layer 3, when photosensitive
Luminescent probe 23 emits beam received by the photosensitive receiving transducer 25 in center after, show that rotate piston pump internal layer 3 lives with rotating
The axis coinciding of pump outer layer 8 is filled in, calibration finishes, and at this time sends enabled instruction, electric car brings into operation.
The operation principle of the present invention：
After the tire of electric car is impacted, referring to Fig. 4, in rotational direction there are a tangential force and power vertically upward,
This can cause tire in rotational direction to accelerate to rotate an angle, and whole tire is moved upwards；The moment to disappear is impacted,
The tire landing beated upwards, causes downward one to impact.The vertical movement that fluid power returns wheel damping disc coordinates tire outer rim
Additional rotation can realize the vibration damping of vertical direction.And the vibration attenuation mechanism of horizontal longitudinal direction is as shown in Figure 2：The linear velocity of tire determines
The movement velocity of vehicle, such as rotate the tire speeds of n circles and be, after being impacted, if to keep the position in axle center constant,
The tire speed for so rotating n circles is, because, so have, thus after being hit, need in rotational direction accelerate to rotate an angle,
Raising tire linear velocity could dissolve tyre rim and be impacted.For vertical vibration, after wheel is impacted, if can keep
The position in axle center is constant, then can eliminates the vibration of vertical direction, in order to reach this target, just must additionally increase wheel
The linear velocity of tire outer rim.Wheel of the present invention can meet above-mentioned 2 points requirement simultaneously after being impacted.Can be automatically according to impulsive force
Big minor adjustment rotational angle and axis wheel position, after being impacted, keep vehicle's center of gravity horizontal level it is constant, dissolved wink
State is impacted.After impact disappears, in the presence of equilibrant force spring, the axle center of tire moves down, and avoids tire landing, causes
A downward impact.Good characteristic possessed by invention so that the effectiveness in vibration suppression of tire greatly improves, so reduce it is dynamic
It is consumable simultaneously, improve the comfortableness of automobile.
Beneficial effects of the present invention
It is wheel hub motor for electric car, used in electric car, direct drive of wheel advance, tire is in wheel hub electricity
On machine shell, after transient impact, tire axis position change, meanwhile, whole tire on the basis moved originally again
One rotation of superposition, rotates an angle so that the linear velocity increase of tire outer rim, so, the movement velocity of vehicle's center of gravity is simultaneously
Do not change, change be tire shaft core position, thus the present invention have can be according to the size dynamic regulation tire of amplitude
Linear velocity, keep vehicle movement process position of centre of gravity it is constant, dissolved transient state horizontally and vertically on impact, can have
Effect reduces the deformation quantity of car wheel structure, reduces rolling resistance, wheel energy consumption is greatly reduced；On the other hand, it is real directly on wheel
Now longitudinal direction and vertically to vibration-damping function, reduce the complexity of vehicle structure, reduce cost.
