Detailed description of the invention
Power input shaft 1 is connected by spline with drive bevel gear 2, and drive bevel gear 2 is meshed with driven wheel of differential 10,
Driven wheel of differential 10 is connected by spline is fixing with left half axle 9, and travelling gear I 8 passes through bonded on left half axle 9, driving cog
Taking turns I 8 to be meshed with travelling gear II 11, travelling gear II 11 is by bonded on jackshaft 5, and electric chuck with three jaws 7 passes through
Spline is connected between on axle 5, and each claw is fixed 1/3 driving pulley 6 respectively, and driven pulley 3 is by key and right half
Axle 4 connects, and V-type band 12 is connected on driving pulley and driven pulley.
The power exported through change speed gear box passes to drive bevel gear 2 through power input shaft 1, and drive bevel gear 2 is by tooth
Engagement imparts power to driven wheel of differential 10, and a torque part for driven wheel of differential 10 passes to left side wheels through left half axle 9, separately
A part passes to jackshaft 5 by gear mesh (travelling gear I 8, travelling gear II 11), and the torque of jackshaft 5 passes to electricity
Dynamic scroll chuck 7, owing to driving pulley (being made up of 3 1/3 driving pulleys 6) is bolted on electric chuck with three jaws 7,
And make driving pulley obtain power.Driving pulley imparts power to driven pulley 3 by V-type band 12, and driven pulley 3 passes through key
It is connected to left half axle 9, so that right wheel obtains power.
Infinitely variable speeds implementation: 3 1/3 driving pulleys 6 are bolted the claw at electric chuck with three jaws 7 respectively
On, as long as controlling claw displacement along radial direction can control the radius of driving pulley, thus control corresponding transmission
Ratio.
When turning to, tire is without the realization of sliding: when motor turning, and the corner of two tires about measurement, controls actively respectively
The gear ratio of belt wheel and driven pulley, makes the wheel speed of right wheel be right up to tire without the speed needed for sliding, so that automobile turns
To time tire without sliding, reduce the abrasion of tire.Simultaneously as belt wheel is by the frictional force transmission moment of torsion of V-type band 12 side, so
When any one side wheel dallies, another side wheel still has input torque, it is to avoid car load " skids ", adds the property passed through of automobile.
The control method of a kind of electrodeless variable-speed type differential mechanism, comprises the steps:
Control the radius of driving pulley by controlling the displacement along radial direction of each claw, thus control corresponding
Gear ratio, the final angular velocity controlling right wheel；When motor turning, system measures the rotational angle theta of two tires about acquisition automatically1
And θ2, control driving pulley radius and make it meet:
Wherein: k is the gear ratio of travelling gear I 8 and travelling gear II 11, RFromFor driven pulley radius, θ1For left side round
Angle, θ2For right-hand wheel corner, the wheel speed of right wheel is made to be right up to tire without the speed needed for sliding, so that motor turning hour wheel
Tire is without sliding.
Assuming that the angular velocity turned is ω, the angular velocity of rotation of revolver is ωLeft, the angular velocity of rotation of right wheel is ωRight, revolver
Linear velocity at core wheel is vLeft, the linear velocity at right wheel core wheel is vRight。
Such as Fig. 3, from Ackermam geometry, at the core wheel of front-wheel left and right two-wheeled, the instantaneous center of velocity of speed is at two trailing wheel core wheels
Line on, front and back core wheel distance is L, so:
Assume that tire radius is R, when tire pure rolling on the ground:
vLeft=ωLeft*R
vRight=ωRight*R
So
Such as Fig. 4, it is assumed that belt wheel radius is respectively RMain、RFrom, k=ω1/ω2
Because belt speed v=ω2*RMain=ω3*RFrom、ω1=ωLeft、ω3=ωRight
Bring (1) formula into so
So only needing to ensureCan ensure tire turn time without sliding.
