A power shift transmission has an input shaft, a first output shaft coaxial to the input shaft, a planetary transmission with a planet carrier, which is connected to the input shaft, and at least three shift elements. To minimize drag from open shift elements and to optimize shift times of a connectable synchromesh transmission, the planetary transmission has at least two stepped planetary sets, which may be mounted on a common planet carrier. Each stepped planetary set meshes on input and output sides with at least one sun gear. The first output shaft is connected to an output side sun associated with one stepped planetary set by a first shift element, the first output shaft is connected to an output side sun associated with another stepped planetary set by a second shift element, and input side sun gears are blocked relative to the transmission housing by a third shift element.

Power shift transmission

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 ().
