And for example, when vehicle 1000a travelings are in uneven road surface or turning driving, the first brake apparatus 63a
First can be respectively braked with the second brake apparatus 64a share the shared gear ring 23a of gear ring 13a and second, this
When both sides the rotating speed of wheel can there is speed discrepancy in theory, by taking left-hand bend as an example, the turning half of left side wheel
Footpath is smaller and the radius of turn of right side wheels is larger, in order to ensure to make PURE ROLLING between wheel and ground,
The rotating speed of left side wheel is less than the rotating speed of right side wheels, now the output speed of the first dynamotor 31a
The output speed of the second dynamotor 32a can be less than, and specific speed discrepancy can be by the steering of steering wheel
Angle is calculated indirectly, and such as driver rotates counterclockwise steering wheel (turning left) certain angle, vehicle
The controller of 1000a is based on the steering angle and can calculate the radius of turn of vehicle 1000a, vehicle 1000a
After radius of turn determines, the relative rotation speed difference of both sides wheel is also determined, now controller controllable first
Dynamotor 31a and the second dynamotor 32a externally export power with the rotating speed for matching respectively so that
The speed discrepancy of the two can be matched with the speed discrepancy needed for wheel, so subtracting by two groups of planetary gears
After speed effect, two wheels are obtained in that desired rotating speed, so as to realize pure rolling turning driving.
