Abstract:
A number of variations may include a product comprising an electrical machine operatively connected to a driveline module comprising a gear train having a fixed gear ratio, a first planetary gear set having multiple gear ratios operatively connected to the gear train, a second planetary gear set having a fixed gear ratio operatively connected to the first planetary gear set, and a synchronizer, wherein the synchronizer is operatively connected to the first planetary gear set and is positioned between the first and second planetary gear set; a differential operatively connected to the second planetary gear set; wherein the electrical machine selectively transmits power to the differential through the gear train, the first planetary gear set, the synchronizer, and the second planetary gear set, and wherein the synchronizer is constructed and arranged to shift the driveline module into a high range mode, a low range mode, and a neutral mode.
