Abstract

A power-split transmission (28) with a first power path and a second power path. In this case, the first power path is a mechanical power path and includes a primary planetary gearset (P1), a secondary planetary gearset (P2) and a tertiary planetary gearset (P3). Furthermore, the power-split transmission (28) is equipped with at least four shifting elements. In addition, a method for operating such a power-split transmission (28) is disclosed. Moreover, a drive-train (10) of a working machine with a power-split transmission (28) of the type concerned is presented.
