Abstract
A drive device includes a frame, a first rotating machine including a fixed part and a rotating part, and a second machine including a fixed part and a rotating part configured to transmit a second torque. A planetary gear train includes a first ring gear, a sun gear and a planet carrier which can rotate with respect to the first ring gear, the rotating part of the first rotating machine being fixed with the planet carrier. Also included is a drive shaft, a differential configured to transmit a resulting torque to the drive shaft. The rotating part of the second machine transmits the second torque to the differential.

Drive device comprising:
- a frame;
- a first rotating machine comprising a fixed part fixed with the frame and a rotating part configured to transmit a first mechanical torque;
- a second rotating machine comprising a fixed part fixed with the frame and a rotating part configured to transmit a second mechanical torque;
- a first planetary gear train comprising a first first ring gear fixed with the frame, a sun gear rotatable relative to the first ring gear and a planet carrier rotatable relative to the first ring gear, the rotating part of the first rotating machine being integral in rotation with the planet carrier of the planetary gear train;
- a drive shaft configured to transmit a resulting torque;
- a differential arranged between the first planetary gear train and the drive shaft in the torque transmission direction, comprising a second ring gear rotationally fixed to the sun gear of the first planetary gear train, the differential being configured to transmit a resultant torque to the drive shaft,
- the drive device being characterized in that the rotating part of the second rotating machine transmits the second torque to the differential.
