Abstract
A variator unit of a power-split continuously variable transmission device is fixed to a rotationally fixed component and has a primary side rotationally fixed to an input shaft and a secondary side rotationally fixed to each respective first element of the first and a second planetary gear sets via a third shaft. A third element of the first planetary gear set is rotationally fixed to a third element of the second planetary gear set via a fourth shaft and is fixable to the rotationally fixed component via a first shift element. A fifth shaft is rotationally fixed to a second element of the second planetary gear set, which is fixable to the rotationally fixed component via the third shift element, and is connectable to the input shaft via the second shift element. A second element of the first planetary gear set is rotationally fixed to the output shaft.
