wherein:
the first planetary gear set has a first sun shaft, a first hollow gear shaft, and a first web shaft;
the second planetary set comprises a second sun shaft, a second hollow gear shaft, and a second web shaft;
the second sun shaft is actuatable by the electric machine;
the second hollow gear shaft is connected to the first web shaft in a rotationally fixed manner;
the first sun shaft is connected to a stationary component in a rotationally fixed manner
the first shift element, in an actuated state, locks the first planetary gear set in order to shift a first gear;
