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.

Abstract: A transmission device for a motor vehicle is disclosed. The transmission device includes at least one coupling unit, which for non-rotatable connection of two coupling elements, has a friction-locking unit and a form-locking unit connected in parallel to the friction-locking unit. The device further includes a first hydraulic and/or pneumatic actuator for actuation of the form-locking unit, a second hydraulic and/or pneumatic actuator for actuating the friction-locking unit, and a directional valve for controlling the first actuator provided for actuation of the form-locking unit. The directional valve has a control line connection which in at least one operational state is connected in pressure terms to the second actuator provided for actuation of the friction-locking unit.
