Motor vehicle drive unit and electrically driven motor vehicle drive axle

A motor vehicle drive unit (1) for an electrically drivable motor vehicle drive axle, comprising:

• an electric machine (2) having an output side;
• a transmission (3) arranged downstream of the output side of the electric machine (2);
• and
• a supply circuit (15) assigned to the electric machine (2) and the transmission (3), in which the electric machine (2) and the transmission (3) are jointly suppliable with lubricant and/or coolant;
• wherein the supply circuit (15) comprises a first collecting region (20) and a second collecting region (30), of which, in the first collecting region (20), a suction side of a conveying device (16) opens, via which lubricant and/or coolant is withdrawable from the first collecting region (20) for supply to the electric machine (2) and the transmission (3);
• wherein the first collecting region (20) is arranged, in a direction of gravity, below the transmission (3) and, in operation of the motor vehicle drive unit (1), is arranged to collect in the supply circuit (15) at least one partial return flow (28, 29), with which lubricant and/or coolant flows off after being supplied from the transmission (3);
• wherein the second collecting region (30) is arranged, in the direction of gravity, below the electric machine (2) and above the first collecting region (20) and, in operation of the motor vehicle drive unit (1), is arranged to collect in the supply circuit (15) at least one partial return flow (34, 35), with which lubricant and/or coolant flows off after being supplied from the electric machine (2);
• and
• wherein the second collecting region (30) is connected to the first collecting region (20), whereby lubricant and/or coolant is dischargeable from the second collecting region (30) into the first collecting region (20).
