Abstract

The invention relates to a motor vehicle drive unit (1) comprising an electric motor (2) and a transmission (3), wherein the electric motor (2) and the transmission (3) are associated with a supply circuit (15) in which the electric motor (2) and the transmission (3) can be supplied with lubricant and / or coolant. The supply circuit (15) has a first collection area (20) and a second collection area (30), into the first collection area (20) of which a suction side of a conveying device (16) opens. The first collection area (20) is arranged in the direction of gravity below the transmission (3) and, during operation of the motor vehicle drive unit (1), captures at least a partial return flow (28, 29) in the supply circuit (15), with which lubricant and / or coolant flows out of the transmission (3) after being supplied.The second collection area (30) is arranged in the direction of gravity below the electric motor (2) and above the first collection area (20) and, during operation of the vehicle drive unit (1), captures at least a partial return flow (34, 35) in the supply circuit (15), with which lubricant and / or coolant flows out after being supplied from the electric motor (2). Furthermore, the second collection area (30) is connected to the first collection area (20), allowing lubricant and / or coolant to be discharged from the second collection area (30) into the first collection area (20).
