摘要： A hybrid four-axis drive apparatus has an engine and a generator on a first axis, a motor on a second axis, a counter gear mechanism on a third axis, and a differential device on a fourth axis. The engine and the generator are connected to the countershaft through a differential gear device. The differential gear device and the countershaft are connected by a first pair of gears. The motor and the countershaft are directly connected by a second pair of gears. The countershaft and the differential device are directly connected by a third pair of gears. Therefore, it becomes possible to change the gear ratio of the pair of gears without changing the positions of the four axes relative to one another. At least one embodiment of the invention has the motor disposed on the first axis, thus, reducing the number of axes to three.

摘要： An inverter is disposed on a cover, lead wires from an electric motor are disposed nearby an output gear in a dead space formed by diameter difference between the output gear and the motor, and the lead wires are routed to the outside of the cover at a position corresponding to the output gear portion. An upper side portion of the electric motor, which is used as a space for routing the lead wires in the conventional unit, can thus be used as a space for disposing the inverter. That is, the inverter can be disposed in the upper side of the vehicle drive unit, which now has available space as compared to the conventional unit. As a result, the vehicle drive unit and the inverter are more compact.
