Abstract
The invention relates to a power shift transmission (). The power shift transmission comprises an input shaft (), a first output shaft () arranged coaxially to the input shaft (), a planetary transmission () having a planet gear carrier (), which is connected to the input shaft (), and at least one dual-stage planetary gear set (), the dual-stage planetary gear set () engaging on the input side with an input-side sun gear () and on the output side with an output-side sun gear () in each case, and at least two shift elements (). To produce a variable power shift transmission for several pairings of various operation modes, the first output shaft () can be connected to the output-side sun gear () of the dual-stage planetary gear set () by means of a first shift element () and the first output shaft () can be directly connected to the input shaft () by means of a second shift element (), the input-side sun gear () of the dual-stage planetary gear set () being non-non-rotatably connected to a housing () of the power shift transmission ().
