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