Abstract
A power-split drive train having a main drive, three output shafts (Ab, Ab, Ab) and a continuously variable powersplit transmission with three additional drive units. The transmission enables rotational speed variability at the shafts (Ab, Ab, Ab). Furthermore, each drive unit () has a respective energy converter () which are all electrically connected. Drive unit () has planetary gearset () that is connected, via a first shaft (W), to the main drive. Shaft (Ab) is connected, via a second shaft (W), to gearset () and energy converter () is connected, via a third shaft (W), to gearset (). The drive unit () is at least indirectly connected to drive unit () which is connected by a fifth shaft (W) to shaft (Ab). Drive unit () is at least indirectly connected to drive unit () which is connected by a seventh shaft (W) to shaft (Ab).
