Abstract: A vehicle drive device is provided that can suppress the increase in dimension in the radial direction while ensuring a sufficient speed reduction ratio. Two driving force sources are arranged on a first axis, two output members are arranged on a second axis, two counter gear mechanisms are arranged on a third axis. A planetary gear mechanism is configured to transmit rotation from the two counter gear mechanisms to the output members, and is disposed so as to overlap with both of the two counter gear mechanisms as seen in an axial direction along and axial direction.

Abstract: A left-right wheel driving device (10) includes: a casing (15) including a reservoir (18) that stores oil; a suction port (19) that is disposed on the reservoir (18) and that sucks the oil from the reservoir (18); and two gears (34) that are each having helical teeth, that are supported so as to be rotatable about a rotating shaft (13) at least in one direction (D), that are provided on a power transmission path that transmits power to left and right wheels of a vehicle, and that are spaced apart from each other. The suction port (19) is positioned between the two gears (34). Each of the gears (34) is offset from the suction port in an axial direction of the rotating shaft (13), being in a state of being partially immersed in the oil stored in the reservoir (18). The helical teeth of each of the gears (34) extend in the one direction (D) and in a direction that departs from the suction port (19).

Abstract: The disclosed vehicle drive device (10) includes: motor housings (11,12), a gearbox housing (13), an inverter case (14), and a PN line (9). The motor housings (11,12) form respective exteriors of a left motor (1) and a right motor (2) that drive left and right wheels of a vehicle with electric power of a battery. The gearbox housing (13) incorporates therein a gearbox (3) that amplifies torque of the left and right motors and that transmits the amplified torque to the left and right wheels, is sandwiched between the left and right motor housings (11,12), and is offset in a front-rear direction from the left and right motor housings (11,12). The inverter case (14) incorporates therein a pair of semiconductor modules (6,7) and is arranged above the left and right motor housings (11,12). The PN line (9) connects the battery to the semiconductor modules (6,7) from a lower surface side of the inverter case (14) so as to pass through a first space (41).
