A power transfer mechanism includes a shift mechanism translating a shift sleeve to a first position where an input shaft is directly drivingly coupled to a first output shaft and to a second position where a reduced speed drive ratio connection exists between the input shaft and the first output shaft as well as the input shaft and a second output shaft via a first planetary gearset. The shift system includes a second planetary gearset having a planet gear fixed for rotation with a lead screw threadingly engaged with the shift sleeve.

Device for transmitting force
The invention relates to a device (1) for transmitting force from an input shaft (4) connected to a drive assembly (2) having constant speed to an output shaft (6) connected to a working machine (3) having variable speed, comprising: a hydrodynamic transducer (20); and a differential transmission designed as a planetary gear unit (1), comprising a ring gear (12), a sun gear (13) and a planet carrier (14) having a plurality of planets (15) as elements of the planetary gear unit. The invention is characterised in that: the hydrodynamic transducer is designed as a counter-movement transducer; the input shaft is directly connected to a pump impeller (7) of the hydrodynamic transducer and a first element (14) of the planetary gear unit; a turbine wheel (10) of the hydrodynamic transducer is directly connected to a second element (13) of the planetary gear unit, and the output shaft is connected at least indirectly to a third element of the planetary gear unit..
