  • Publication number: 20230364979
    Abstract: A transmission mechanism transmits rotation transmitted from a distribution differential gear mechanism to an output member. The distribution differential gear mechanism, a first distribution output gear, and a first engagement device are disposed on a first axis. A first rotary electric machine and a first rotary electric machine drive gear are disposed on a second axis. A transmission engagement device of the transmission mechanism is disposed on a third axis. An axial direction of the first rotary electric machine includes a first axial side where the first rotary electric machine is disposed with respect to the first rotary electric machine drive gear, and a second axial side opposite to the first axial side. The distribution differential gear mechanism is disposed on the second axial side of the first distribution output gear and the first engagement device.

  • Publication number: 20230365122
    Abstract: A vehicle speed is lower than a first threshold, a control device controls both a first drive unit and a second drive unit to output a requested driving force by setting an operation mode of the first drive unit to a first mode when the requested driving force is smaller than a second threshold and the charge level of a power storage device is equal to or higher than a third threshold, and controls both the first drive unit and the second drive unit to output the requested driving force by setting the operation mode of the first drive unit to a second mode when the requested driving force is equal to or larger than the second threshold or the charge level of the power storage device is lower than the third threshold.

  • Patent number: 11407301
    Abstract: 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.
