| 摘要 |
The invention relates to a hydrodynamic mechanical multispeed compound gearbox with a gear box input shaft (E), an output (A1, A2), a hydrodynamic gearbox part (2) and a mechanical gearbox part (4) which is arranged after said hydrodynamic gearbox part and which comprises at least one speed/torque converter device (5), whereby the mechanical speed/torque converter device (5) has at last two planetary gear sets (7, 8). The planetary gear sets (7, 8) are designed and arranged in such a way that an element of the first planetary gear set (7) and of the second planetary gear set (8) can each be at least indirectly coupled to the gearbox input shaft (E) or to an element of the hydrodynamic speed/torque converter device (5). In addition, an additional second element of the first planetary gear set (7) is respectively coupled to an additional second element of the second planetary gear set (8) in a rotationally fixed manner. This coupling forms the output (9) of the mechanical speed/torque converter device (5).
