摘要： A vehicle drive device is disclosed that includes a rotating electrical machine, a transmission mechanism, an inverter device, a case including a first case portion that houses the rotating electrical machine, and a rotor shaft to which a rotor is fixed. The rotating electrical machine and a pair of output members have a two-axis configuration. The transmission mechanism includes, coaxially with the pair of output members, an output gear drivingly connected to at least one of the pair of output members. The output gear is disposed so as to overlap each of the rotating electrical machine and the inverter device as viewed in an axial direction. The inverter device is disposed so as to overlap a first output member that is one of the pair of output members, as viewed in an up-down direction. The first output member is disposed so as to overlap an axis of the rotor shaft as viewed in a horizontal direction, and the inverter device is disposed below an uppermost position of the first case portion in a second direction.

摘要： A vehicle drive device is disclosed that includes a rotating electrical machine, a transmission mechanism, and an inverter device. The rotating electrical machine and a pair of output members have a two-axis configuration. The transmission mechanism includes, coaxially with the output members, an output gear drivingly connected to the output members. A first output member that is one of the pair of output members is interposed between the rotating electrical machine and the inverter device in a horizontal direction at a position in an up-down direction where both the rotating electrical machine and the inverter device are disposed. The output gear overlaps each of the rotating electrical machine and the inverter device as viewed in an axial direction. The inverter device is disposed on the opposite side of the first output member from the rotating electrical machine and above the first output member. A case includes a peripheral wall portion that separates the first output member and the inverter device from each other. The peripheral wall portion overlaps the output gear as viewed in the axial direction.

摘要： A vehicle drive device is disclosed that includes a rotating electrical machine, a transmission mechanism, and an inverter device. The rotating electrical machine and a pair of output members have a two-axis configuration. The transmission mechanism includes, coaxially with the pair of output members, an output gear drivingly connected to at least one of the pair of output members. The inverter device is disposed so as to overlap a first output member that is one of the pair of output members as viewed in a direction along an up-down direction. A first coolant channel through which a coolant for cooling the rotating electrical machine passes and a second coolant channel through which a coolant for cooling the inverter device passes are provided in the case so as to communicate with each other.
