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