A vehicle drive system, including a motor generator; a gear group having a plurality of gears; and a motor cooling circuit for cooling the motor generator. The system further includes a lubricating circuit for lubricating the gear group; a cooler circuit in which an oil cooler is provided; and an oil pump that supplies oil to each circuit. The motor cooling circuit is arranged in series with and downstream of the cooler circuit, and the lubricating circuit is arranged parallel to the cooler circuit with respect to the oil pump.

Vehicle drive system

An electrical connection structure that includes a first connection portion of the connection member that is fixedly fastened to the first terminal by a fastening bolt, and a second connection portion of the connection member that is connected to the second terminal through an insertable/removable plug, the first connection portion is fixedly fastened to the first terminal by inserting the fastening bolt through an insertion hole provided in one of the connection member and the first terminal, and fastening the fastening bolt in a fastening hole provided in the other of the connection member and the first terminal, the insertion hole is formed larger than a diameter of a shaft-like portion of the fastening bolt, and an inserting/removing direction of the plug and an axial direction of the fastening bolt are substantially parallel to each other.

Electrical connection structure

A drive device includes an input shaft connected to an engine; a first rotating electrical machine and a second rotating electrical machine; a differential gear unit including a first rotating element, a second rotating element, and a third rotating element; and a control device. The first rotating electrical machine and the differential gear unit are positioned coaxially with the input shaft. The first rotating electrical machine and the second rotating electrical machine are positioned on different axes from each other so as to axially overlap each other. A first component of the control device is positioned lower than the first rotating electrical machine and positioned so that at least a part of the first component overlaps the first rotating electrical machine when viewed in a vertical top plan view.
