1. A motor vehicle comprising:
at least one electric drive machine for driving the motor vehicle,
at least one coupling mechanism switchable at least between a coupling position, in which the electric drive machine is coupled to a drive wheel of the motor vehicle in a torque-transmitting manner, and a decoupling position, in which the electric drive machine is decoupled from the drive wheel,
a parking lock device comprising at least one parking lock element movable between a parking lock position, in which the at least one parking lock element at least indirectly blocks a rotation of the drive wheel, and an unlocking position, in which the at least one parking lock element releases rotation of the drive wheel, and
at least one actuating device with an actuator configured to actuate a clutch that switches the coupling mechanism between the coupling position and the decoupling position, and to displace the at least one parking lock element between the parking lock position and the unlocking position,
wherein the clutch has at least one switching element, preloaded by spring force on a housing of the coupling mechanism, and serves for switching between the coupling position and the decoupling position,
wherein the at least one actuating device comprises an actuating element which can be adjusted by way of the actuator and which is configured, on the one hand, to exert at least one switching force on the switching element for actuating the clutch and, on the other hand, to exert at least one moving force, for moving the at least one parking lock element between the parking lock position and the unlocking position, and
wherein the actuating element is at least indirectly coupled to an eccentric element of the actuating device in a force-transmitting manner via a second spring element of the actuating device, by way of which eccentric element the parking lock element can be displaced between the parking lock position and the unlocking position.
