In a left-right wheel drive device () that accommodates, in a casing (), two electric motors () spaced apart from each other and a planetary gear mechanism () arranged so as to be offset on a first side in an axial direction, a pair of motor shafts (), a pair of counter shafts (), and two output shafts () are arranged in parallel. The first output shaft () is arranged on the first side from the planetary gear mechanism () and is fixed with a carrier (C) at an end portion of a second side thereof. The second output shaft () is longer than the first output shaft () and is fixed with the second sun gear (S) at an end portion on the first side thereof. The second output shaft () is rotatably supported by roller bearings () at the end portion on the second side and a position on the second side from a driven gear meshing with the second counter gear.

Left-right wheel drive device

The driving apparatus comprising a first motor, a first gear mechanism having a first input shaft and a first output shaft connected to the first motor, a second motor, and a second gear mechanism having a second input shaft and a second output shaft connected to the second motor. The first gear mechanism is configured such that the first input shaft and the first output shaft are in an intersecting or twisted position, and the second gear mechanism is configured such that the second input shaft and the second output shaft are in an intersecting or twisted position.

Driving apparatus

A vehicle drive device is provided that can suppress the increase in dimension in the radial direction while ensuring a sufficient speed reduction ratio. Two driving force sources are arranged on a first axis, two output members are arranged on a second axis, two counter gear mechanisms are arranged on a third axis. A planetary gear mechanism is configured to transmit rotation from the two counter gear mechanisms to the output members, and is disposed so as to overlap with both of the two counter gear mechanisms as seen in an axial direction along and axial direction.

Vehicle drive device

A first case portion includes an end wall portion disposed on a first axial side with respect to a transmission. A second case portion is disposed on the first axial side with respect to a rotor of a rotary electric machine, and includes a first support portion that supports a rotor shaft and a second support portion disposed on a second axial side with respect to the rotor of the rotary electric machine to support the rotor shaft. The second support portion includes a bearing attachment portion to which a rotor bearing for supporting the rotor shaft is attached, and radially extending portion that extends from bearing attachment portion toward an outer side in a radial direction. A speed reducer is disposed between the radially extending portion and the end wall portion in axial direction to face the radially extending portion and the end wall portion in the axial direction.
