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);
• 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 (B2), selective actuation of the first, second and third shift elements (B1, K1, B2) implements different power paths via the variator unit (10) and the first and second planetary gear sets (RS1, RS2) while making a first mode (V1), a second mode (V2), and a third mode (R1) 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 is rotationally fixed to a first element (E21) of the second planetary gear set (RS2) via a third shaft (3),
• wherein a third element (E13) of the first planetary gear set (RS1) is rotationally fixed to a second element (E22) of the second planetary gear set (RS2) via a fourth shaft (4), the second element (E22) of the second planetary gear set (RS2) fixable to the rotationally fixed component (GG) via the first shift element (B1) and connectable to the input shaft (1) via the second shift element (K1),
• wherein a third element (E23) of the second planetary gear set (RS2) is rotationally fixed to a first element (E11) of the first planetary gear set (RS1) via a fifth shaft (5), the first element (E11) of the first planetary gear set (RS1) fixable to the rotationally fixed component (GG) via the third shift element (B2), and
• wherein the second element (E12) of the first planetary gear set (RS1) is rotationally fixed to the output shaft (2).
