DRIVE DEVICE FOR A DRIVE SHAFT COMPRISING TWO ROTATING MACHINES

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.
