Patent ID: 8597150

Claim:
A drivetrain for an all-wheel drive motor vehicle, the drivetrain comprising: a first driveline that is adapted to drive a pair of first vehicle wheels, the first driveline including a first differential and a pair of first axleshafts, the first differential having a first differential case and a pair of first output gears driven by the first differential case, the first axleshafts being drivingly coupled to the first output gears and to the first vehicle wheels; a power switching mechanism having an input shaft adapted to rotate with the first differential case, an output pinion shaft, and a disconnect mechanism, the disconnect mechanism being operable in a disconnected mode, which inhibits transmission of rotary power between the input shaft and the output pinion shaft, and in a connected mode that permits transmission of rotary power between the input shaft and the output pinion shaft; and a second driveline that is adapted to drive a pair of second vehicle wheels, the second driveline including a propshaft and a drive module, the drive module including an input pinion shaft, a second differential, a pair of second axleshafts, which are adapted to be drivingly coupled to the pair of second vehicle wheels, a torque transfer device, and a limited slip clutch assembly, the second differential having a second differential case and a pair of second output gears that are driven by the second differential case, the second output gears being drivingly coupled to the second axleshafts, the input pinion shaft being coupled by the propshaft to the output pinion shaft of the power switching mechanism, the torque transfer device being operable in a first switching mode, which inhibits transmission of rotary power between the input pinion shaft and the second differential case, and in a second switching mode that permits transmission of rotary power between the input pinion shaft and the second differential case, the limited slip clutch assembly being operable in a first clutch mode, which permits speed differentiation between the second differential case and one of the second axleshafts, and in a second clutch mode that inhibits speed differentiation between the second differential case and said one of the second axleshafts.
