ABSTRACT:
A vehicle with a primary driveline that is configured to distribute rotary power to a first set of vehicle wheels, a power transmitting device and a secondary driveline that is configured to distribute power to a second set of vehicle wheels. The power transmitting device has an input member, which is driven by the primary driveline, and an output member that is selectively coupled to the input member to receive rotary power therefrom. The secondary driveline has a propshaft, an axle input, a pair of axle shafts and at least one torque transfer device. The propshaft transmits rotary power between the output member of the power transmitting device and the axle input. The axle shafts are rotatably coupled to an output of the differential and configured to transmit rotary power to the second set of vehicle wheels. The at least one torque transfer device is configured to selectively inhibit torque transmission between the axle input and the second set of vehicle wheels.
