Abstract: A drive mechanism comprises a transmission as well as an electromotor/generator. The transmission is connected via an input to the electromotor/generator and via an output to the wheels. The transmission has two planetary gear sets having three rotational members each, of which first rotational members are connected to the input, second rotational members are connected to the output and third rotational members are connected to a first and second brake respectively. By actuating either of the brakes a speed transforming gear is created between the input and the output. By actuating one brake during the releasing of the other brake, it is possible to switch between the two speed transforming gears without an interruption of the torque transfer from the electromotor/generator to the load or vice versa.

The transmission system has an epicyclic gearing with three rotational members a first rotational member connected to the drive source, a second rotational member connected to the wheels via a first reduction and a final reduction and a third rotational member connected to a brake. The brake constitutes reaction means for balancing torque. The transmission system also includes a transmission parallel to the epicyclic gearing and a transmission in series with the epicyclic gearing. Moreover, the transmission system has a lock-up clutch capable of connecting the first rotational member to the second rotational member. This transmission system enables shifting between various transmission ratios without torque interruption, using only one brake. The transmission in series with the epicyclic gearing can directly be connected to the load via the lock-up clutch or via the ‘braked ’ planetary set.
