Abstract
A motive power assembly for a vehicle with hybrid motorization functioning in a plurality of modes. The assembly includes a first planetary gear train having a first annulus, a first planet wheel, a first planet carrier and at least one first planet, linked in rotation to an output shaft of an electric motor, an output shaft of an internal combustion engine, a shaft of a rotor of an alternator and a power output to transmit motive power to wheels of the vehicle via a bridge. Also included is an electronic module for controlling an amount of charge of a battery package delivered to the electric motor and the alternator. A second planetary gear train is also provided and includes a second annulus, a second planet wheel, a second planet carrier and at least one second planet, one of which is linked in rotation to the output shaft of the electric motor and the others of which are linked to the power output of the first planetary gear train and to the bridge. The electronic module actuates an operation of the internal combustion engine, and a locking mechanism locks the output shaft of the internal combustion engine. Further, the first planetary gear train is coaxial with the second pla…
