Vehicle drive device

A vehicle drive device comprising:

• an input member drivingly connected to an internal combustion engine;
• an output member drivingly connected to wheels;
• a rotary electric machine including a rotor;
• a rotary electric machine drive gear drivingly connected to the rotor;
• a transmission mechanism including a transmission engagement device configured to switch a state of power transmission;
• a distribution differential gear mechanism including a first rotation element drivingly connected to the input member, a second rotation element drivingly connected to the transmission mechanism, and a third rotation element drivingly connected to the rotary electric machine drive gear;
• a first distribution output gear connected to the second rotation element so as to rotate integrally with the second rotation element;
• a disconnection engagement device configured to connect or disconnect power transmission between the input member and the first rotation element, wherein
• the transmission mechanism is configured to transmit rotation transmitted from the distribution differential gear mechanism to the output member,
• the distribution differential gear mechanism, the first distribution output gear, and the disconnection engagement device are disposed on a first axis,
• the rotary electric machine and the rotary electric machine drive gear are disposed on a second axis different from the first axis,
• the transmission engagement device is disposed on a third axis different from the first axis and the second axis,
• an axial direction of the rotary electric machine includes a first axial side where the rotary electric machine is disposed with respect to the 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 disconnection engagement device, and
• the transmission engagement device overlaps the first distribution output gear in a radial view along the radial direction;
• and
• a second distribution output gear connected to the third rotation element so as to rotate integrally with the third rotation element, wherein
• the distribution differential gear mechanism is a planetary gear mechanism including a sun gear, a carrier, and a ring gear,
• the third rotation element is the ring gear,
• the second distribution output gear is disposed on the first axis and on an outer side in a radial direction with respect to the ring gear,
• the transmission mechanism includes a first gear disposed on the third axis and meshing with the second distribution output gear, and
• the ring gear and the second distribution output gear overlap each other in a radial view along the radial direction.
