The planetary transmission includes a transmission input shaft connected indirectly to the rotor and includes a transmission output shaft connected to the generator indirectly via a generator shaft. A coupling mechanism is arranged between the generator shaft and the planetary transmission to compensate axial, radial and angular misalignment.

A preload control unit is configured to operate the switching apparatus to apply a preload to the synchromesh mechanism when a shift transmission request is detected.

Abstract: An epicyclic gear system includes sun and ring gears (2, 4), planet pinions (6, 8) arrayed (a, b) between these gears, and a carrier (10) to which planet pinions are coupled through flexpins (30). The pinions are located between carrier walls (20, 22) with flexpins for the respective arrays cantilevered from opposite walls. The carrier is subjected to externally applied torque which transfers through the system. The load path (pa) for one array is shorter than that (pb) for the other array, which disparity causes carrier distortion with flexpins on one wall angularly displaced from flexpins on the other wall. The system compensates for this by one wall having areas (40, 44) of weakness where the flexpins cantilever from it. This enables the pinions of the two arrays to better mesh under a load and share torque transfer more evenly.

As a result, for the HV-MT vehicle, by using the internal-combustion-engine torque, the battery for supplying the electric motor with the electric energy can be efficiently charged.
