| 摘要 |
The invention relates to a transmission unit having a continuously variable transmission part (3) and a mechanical transmission part (4) comprising a four-shaft planetary gear (5), the part comprising a first planetary gear set (8) and a second planetary gear set (1) and being connected selectively to the output (A) via a first clutch device (K1) or a second shiftable clutch device (K2). The invention is characterized in that the first planetary gear set (8) and the second planetary gear set (10) of the planetary gear (5) each comprise a first shaft (11, 12) and a second shaft (13, 15), wherein the first shafts (11, 12) are rotationally fixed to each other and connected at least indirectly to the transmission input (E), and the second shaft of the first planetary gear set (8) is connected to the continuously valiable transmission part (3) and the second shaft (15) of the second planetary gear set (9) is connected to an input part (16) of the first clutch device (K1). The first planetary gear set (8) comprises a third shaft (14) connected to the continuously variable transmission (3), wherein the third shaft (14) can be further connected to the output (A) via the second clutch device (K2).
