ABSTRACT:
A power shift transmission (10) for a movable machine comprises an input shaft (9) driven by an engine (1), an output shaft (8), at least one mechanical drive line (13) and at least two separate hydrostatic drive lines (4, 5). Each of the hydrostatic drive lines (4, 5) comprises a separate shaft (32, 43) and is designed to be coupled to the output shaft (8) via synchronizing devices (34, 35, 45, 46, 47) and gear units. The at least two hydrostatic drive lines (4, 5) are arranged in parallel. At least one power shift clutch (15) is arranged at the input end of each of the at least one mechanical driving (13) line and at least one power shift clutch (40, 42) is arranged at the input end of each of the at least two hydrostatic drive lines (4, 5).
