ABSTRACT:
A vehicle comprises a drive source that drives the wheels via a transmission system. 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.
