Abstract: A vehicle drive device (10) includes: a motor unit (1) that includes a motor for driving mounted on a vehicle and a gear mechanism that transmits torque of the motor to each of left and right wheels of the vehicle; and an inverter (4) that is arranged over the motor unit (1) and that includes a capacitor (5) smoothing electricity and a semiconductor module (6) including a plurality of switching elements, wherein the inverter (4) includes a tray unit (16) that accommodates the capacitor (5) and the semiconductor module (6), and a cover (15) that is in a flat-plate shape, is attached to the tray unit (16), and covers the capacitor (5) and the semiconductor module (6) from above the capacitor (5) and the semiconductor module (6), the cover (15) is integrated with a cooling unit (20) through which a coolant for cooling the inverter (4) flows, and the capacitor (5) and the semiconductor module (6) are attached to a lower surface (17) of the cover (15).

Abstract: The disclosed vehicle drive device (10) includes: left and right motors (1,2) that drive left and right wheels of the vehicle; a gearbox (3) that is sandwiched between the left and right motors (1,2); and an inverter (4) that is arranged in a mounting space (S) over the left and right motors (1,2) and the gearbox (3). The gearbox (3) forms, in conjunction with respective motor housings (11,12) of the left and right motors (1,2), a depressed portion (8) depressed downward. The inverter (4) includes a cover (15) that is in a flat-plate shape, is attached to a tray unit (16), and covers the capacitor (5) and a semiconductor module (6) from above the capacitor (5) and the semiconductor module (6). The capacitor (5) is attached to a lower surface of the cover (15) and is arranged in the depressed portion (8). The semiconductor module (6) is attached to the lower surface of the cover (15) and is displaced from each of the capacitor (5) and the rotating shafts (C) of the motors (1,2) when seen from above.

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).
