<p>The invention relates to a power shift transmission (10). The power shift transmission (10) comprises an input shaft (18), a first output shaft (20) arranged coaxially to the input shaft (18), a planetary transmission (22) that has a planet carrier (28), which is connected to the input shaft (18) and at least three shift elements (24, 26, 68). In order to minimize drag losses caused by open shift elements (24, 26, 68) and to optimize shift times of a connectable synchromesh transmission, the planetary transmission (22) comprises at least two stepped planetary sets (30, 32) that are mounted on the common planet carrier (28), wherein each stepped planetary set (30, 32) meshes on the input side and the output side with a sun (50, 62, 52, 64), the first output shaft (20) can be connected to the output side sun (62) of the one stepped planetary set (30) by means of the first shift element (24), the first output shaft (20) can be connected to the output side sun (64) of the other stepped planetary set (32) by means of the second shift element (26), and the input-side sun gears (50, 52) of the two stepped planetary sets (30, 32) can be blocked in relation to the transmission housing by means of the third shift element (68).</p> |
