If one rotation speed of motor is greater than two rotation speed of motor, bi-bevel gear one (6) drives bevel planet gear one
(14) it is greater than bi-bevel gear two along the rotation speed of one direction of rotation of bevel planet gear (48) around planet axis axis (49)
(16) driving bevel planet gear one (14) is around planet axis axis (49) along the rotation of one direction of rotation of bevel planet gear (48)
Speed, in order to offset the speed difference, bevel planet gear one (14) can also revolve around output shaft axis (47), bevel planet gear one
(14) driving planet stent (12) slow-speed of revolution rotation, planet stent (12) linear velocity are equal to bi-bevel gear one (6) rotational line
The difference of speed and bi-bevel gear two (16) linear velocity；Planet stent direction of rotation (43) and one direction of rotation of bi-bevel gear
(52) identical, planet stent (12) respectively drives output bevel gear wheel one (8) and output bevel gear wheel two by bevel planet gear two (9)
(15) slow-speed of revolution rotating Vortex, automobile move forward；
If two rotation speed of motor is greater than one rotation speed of motor, bi-bevel gear two (16) drives bevel planet gear one
(14) it is greater than bi-bevel gear one (6) along the rotation speed of one direction of rotation of bevel planet gear (48) around planet axis axis (49)
The rotation speed of bevel planet gear one (14) around planet axis axis (49) along one direction of rotation of bevel planet gear (48) is driven,
In order to offset the speed difference, bevel planet gear one (14) can also revolve around output shaft axis (47), bevel planet gear one (14)
Planet stent (12) slow-speed of revolution rotation is driven, planet stent (12) linear velocity is equal to bi-bevel gear two (16) linear velocity
And the difference of bi-bevel gear one (6) linear velocity；Planet stent direction of rotation (43) and two direction of rotation of bi-bevel gear (46) phase
Together, planet stent (12) respectively drives output bevel gear wheel one (8) by bevel planet gear two (9) and output bevel gear wheel two (15) is low
Revolving speed rotating Vortex, automobile travel backward；
When one rotation speed of motor and two rotation speed of motor are unequal, planet stent (12) passes through bevel planet gear two
(9), output bevel gear wheel one (8) drives output shaft one (5) slow-speed of revolution rotating Vortex, meanwhile, planet stent (12) is bored by planet
Gear two (9), output bevel gear wheel two (15) drive output shaft two (18) slow-speed of revolution rotating Vortex；The inboard wheel when automobile turning
Bigger resistance can be generated, bevel planet gear two (9) around output shaft axis (47) while revolving, bevel planet gear two
(9) planet axis axis (49) rotation can also be surrounded；If automobile is turned to the left, output bevel gear wheel one (8) angular velocity of rotation is greater than
Planet stent (12) angular velocity of rotation, meanwhile, output bevel gear wheel two (15) angular velocity of rotation is less than planet stent (12) rotation angle
Speed；If automobile is turned to the right, output bevel gear wheel two (15) angular velocity of rotation is greater than planet stent (12) angular velocity of rotation, together
When, output bevel gear wheel one (8) angular velocity of rotation is less than planet stent (12) angular velocity of rotation；Cause output bevel gear wheel one (8) logical
Crossing output shaft one (5) drives the rotation speed of right wheel and output bevel gear wheel two (15) to pass through output shaft two (18) driving left wheel
Rotation speed it is unequal, outboard wheels rotation speed is faster than inboard wheel rotation speed, it is ensured that automobile can smoothly turn.
