| 摘要 |
The invention relates to a transmission system with speed variation, designed in particular for an electrically actuated vehicle.
<??>The system is actuated by a manual control which includes a power source consisting of an electric motor (1) with relative rotation, including an external stator which can turn with respect to an internal rotating rotor, so that the power leaving the external stator or the central rotor can be transmitted respectively to a front differential mechanism (1D) and to a rear differential mechanism (2D), of the vehicle; the transmission shafts (21, 22) respectively provided between the electric motor (1) and the front and rear differentials (1D, 2D) can be selectively locked so that the power supplied by the motor (1) can be selectively altered when it is applied to the differentials, in order to correspondingly alter the speeds of the wheels of the motor vehicle.
<??>Application to remote-control electric motor vehicles.
