摘要

The transmission device (3) comprises a transmission input shaft (4), which is coupled with a drive unit (2) of a vehicle drive train (1), and a transmission output shaft (7), which is connected with an output unit (5) of the vehicle drive train. A pivot shaft (8) is provided, which is coupled with the transmission output shaft by a switchable coupling unit (9). An infinitely variable power-split transmission portion (11) and the transmission output shaft are coupled by one of the coupling unit assigned to the transmission output shaft.
