Zusammenfassung:	A transmission for an at least partially electrically driven vehicle includes two electric machines which are rotationally driveable in a first direction and in a second direction. The transmission further includes an output shaft at least indirectly operatively connected to the first and second electric machines, a first freewheel clutch that at least indirectly transmits a drive power of the first electric machine to the output shaft with a first ratio when the first electric machine rotates in the first direction, and a second freewheel clutch that at least indirectly transmits the drive power of the first electric machine to the output shaft with a second ratio when the first electric machine rotates in the second direction. Additionally, the transmission includes at least one first gear stage in power flow between the first or second freewheel clutch and the output shaft to rotate the output shaft in a third direction.
