| 摘要 |
The invention concerns a superimposed transmission for driving a rotational speed-variable work machine having the following design: an input shaft (2) is connected to an intermediate shaft (3); a pump wheel (5) of a hydrodynamic converter (6) rotates with the intermediate shaft (3); a turbine wheel (7) of the hydrodynamic converter (6) rotates with a superposition means; the intermediate shaft (3) and the transmission means are connected to an output shaft (4) by means of a differential gear (14); and the transmission means is designed as at least one coupling shaft (10), which connection the turbine wheel (7) of the hydrodynamic converter (6) to the differential gear (4). To do so, said at least one coupling shaft (10) runs parallel to the intermediate shaft (3). In a particularly favourable variation, an additional hydrodynamic converter (15) can be present and/or the coupling shaft (10) can be connected in an engageable manner directly to the input shaft (2) by means of an additional transmission (18) for starting the transmission. |
