Abstract
A disconnectable driveline arrangement for an all-wheel drive vehicle includes a power take-off unit having a disconnect mechanism, a rear drive module having a torque transfer device providing a disconnect function, a speed synchronization function and a torque biasing function, and a control system for controlling actuation of the disconnect mechanism and the torque transfer device. The power take-off unit and the rear drive module can each be equipped with a two-speed range shift unit which, under the control of the control system, permits establishment of high and low speed drive connections.
