Abstract
A system is provided for transmitting torque with speed modulation between a motor generator and an engine. The system includes a first shaft, a second shaft, a first reduction gearset, and a second reduction gearset. The first shaft is configured to rotatably connect with the motor generator. The second shaft is configured to rotatably connect with the engine. The first reduction gearset is rotatably supported at least in part on the first shaft. The first reduction gearset is disposed in selective engagement with the first shaft via a first overrunning clutch disposed therebetween. The second reduction gearset is rotatably supported at least in part on the first shaft and at least in part on the second shaft. The second reduction gearset is disposed in selective engagement with the first shaft via a second overrunning clutch disposed therebetween.
