摘要:
An electric drive for a motor vehicle includes a housing, an output shaft, an electric engine, which has a stator and a rotor rotatable relative to the stator, a planetary gear set arranged in the housing, which has a sun gear, a ring gear and a planetary carrier, which is non-rotatably connected to the output shaft, having a first switching element, by means of which the ring gear can be non-rotatably coupled to the rotor, and a second switching element, by means of which the ring gear can be non-rotatably coupled to the housing. The first switching element and the second switching element are coupled to each other via a first coupling element and thereby can be operated together by a single first actuator common to the first switching element and the second switching element.
