Power-split continuously variable transmission device

A power-split continuously variable transmission device (100), comprising:

• an input shaft (1);
• an output shaft (2);
• a first planetary gear set (RS1) arranged between the input shaft (1) and the output shaft (2);
• a second planetary gear set (RS2) connected to the first planetary gear set (RS1) and arranged between the input shaft (1) and the output shaft (2);
• a third planetary gear set (RS3) connected to the second planetary gear set (RS2) and arranged between the input shaft (1) and the output shaft (2);
• and
• a variator unit (10) for transmitting power in a continuously variable manner from the input shaft (1) to the first planetary gear set (RS1), the variator unit (10) having a first shift element (B1), a second shift element (K1) and a third shift element (K2), selective actuation of the first, second and third shift elements (B1, K1, K2) providing different power paths between the input shaft (1) and the output shaft (2) while making a first mode (FB1), a second mode (FB2) and a third mode (FB3) available,
• wherein the variator unit (10) is fixed to a rotationally fixed component (GG), a primary side (11) of the variator unit (10) is rotationally fixed to the input shaft (1), and a secondary side (12) of the variator unit (10) is rotationally fixed to a first element (E11) of the first planetary gear set (RS1),
• wherein the input shaft (1) is rotationally fixable to a second element (E22) of the second planetary gear set (RS2) via the second shift element (K1), and the input shaft (1) is rotationally fixed to a first element (E31) of the third planetary gear set (RS3),
• wherein a second element (E12) of the first planetary gear set (RS1) is fixed to the rotationally fixed component (GG),
• wherein the second element (E22) of the second planetary gear set (RS2) is fixable to the rotationally fixed component (GG) via the first shift element (B1),
• wherein a first element (E21) of the second planetary gear set (RS2) is rotationally fixed to a third element (E33) of the third planetary gear set (RS3),
• wherein a third element (E13) of the first planetary gear set (RS1) is rotationally fixed to a third element (E23) of the second planetary gear set (RS2),
• wherein a second element (E32) of the third planetary gear set (RS3) is rotationally fixed to the output shaft (2) and is rotationally fixable to the third element (E13) of the first planetary gear set (RS1) and the third element of the second planetary gear set (RS2) via the third shift element (K2).
