A front drivetrain capable of providing all-wheel drive to a rear-wheel drive architecture. The front drivetrain is coupled to the front end of the crank shaft and includes a power-split planetary gear arrangement that couples an electric machine to the front drivetrain. In one embodiment, the planetary gear arrangement includes a sun gear coupled to the crank shaft, a planetary gear set with a carrier coupled to the driveshaft, a ring gear coupled to the electric machine. The driveshaft may be connected to left and right front axles by a bevel gear set and a differential. In an alternative embodiment, sun gear may be coupled to the electric machine and the ring gear can be coupled to the crank shaft. In this alternative embodiment, the planetary gear set remain coupled to the driveshaft. |
