Title:
DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2021116857
Kind Code:
A
Abstract:
To provide a technique capable of miniaturizing axial dimension of a driving device including a driving motor and a torque vector ring motor.SOLUTION: A driving device 10 in one embodiment of this disclosure comprises: a driving motor 11 that is a driving force source of a vehicle 1; right and left planetary gear mechanisms 13, 14 for transmitting power of the driving motor 11 to right and left driving wheels 40, 50 respectively; a reverse rotation gear pair 17 for rotating rotation shafts of sun gears 13S, 14S to which power from the driving motor 11 is inputted, among three rotation shafts of right and left planetary gear mechanisms 13, 14 and rotation shafts of ring gears 13R, 14R except for rotation shafts of planetary carriers 13C, 14C for outputting power to the driving wheels 40, 50 in directions opposite to each other; and a torque vector ring motor 18 for driving the reverse rotation gear pair 17. The right and left planetary gear mechanisms 13, 14, and at least one of the driving motor 11 and the torque vector ring motor 18 are arranged so that axial cores of the rotation shafts are almost coincident with each other.SELECTED DRAWING: Figure 1
