ABSTRACT:
A sun gear of a first planetary gear train is connected to an input shaft. A carrier9of the first planetary gear train is connected to a sun gear of a second planetary gear train and to a first pump/motor. A ring gear of the first planetary gear train is connected to a second pump/motor, and a ring gear of the second planetary gear train is connected to an output shaft. A first clutch is provided for engaging and disengaging a carrier of the second planetary gear train and the ring gear of the first planetary gear train with and from each other, and a second clutch is provided for engaging and disengaging the carrier of the second planetary gear train and a fixed end with and from each other.
