Abstract
A power-split drive train for a working machine having a main drive element, drive output shafts (Ab, Ab, Ab), and a continuous power-split transmission with three drive units (). The transmission enables all three output shafts to be operated at the same time with rotational speed variability. A first drive unit () has two energy converters while second and third drive units () each comprise one energy converter. All four energy converters are functionally connected to an electric line. The first unit () is connected, via a first shaft, to the main drive element and, via a second shaft, to output shaft (Ab). The first unit () is connected to drive unit () which is connected, via a third shaft, to output shaft (Ab). The first drive unit () is connected to drive unit () which is connected, via a fourth shaft, to output shaft (Ab).
