Abstract

A drive device for a motor vehicle includes an electric machine having a gearbox where the motor vehicle is drivable electrically via the gearbox by the electric machine. At least one gear of the gearbox is switchable by operating a switch element. A medium is flowable through a circuit that has a first branch through which the medium is flowable to cool and/or lubricate the electric machine and/or the gearbox and a second branch through which the medium is flowable to operate the switch element. A pump delivers the medium through the circuit. The medium is flowable through a third branch of the circuit to operate the parking lock.
