A variator unit is fixed to a rotationally fixed component and has a secondary side rotationally fixed to an input shaft and a primary side rotationally fixed to a first element of a first planetary gear set. The input shaft is rotationally fixable via a second shift element to a second element of a second planetary gear set, which is fixable to the rotationally fixed component via a first shift element, and is rotationally fixed to a first element of a third planetary gear set. A second element of the first planetary gear set is fixed to the rotationally fixed component. A first element of the second planetary gear set is rotationally fixed to a third element of the third planetary gear set. A third element of the first planetary gear set is rotationally fixed to a third element of the second planetary gear set.
