Abstract

A drive train system comprising a power transfer unit configured to selectively transfer power from a front driveshaft of a vehicle by providing an output torque through a ring gear, wherein the power transfer unit includes an input shaft that receives torque from a first device, and a first clutch configured to selectively couple the input shaft to the ring gear when activated; a cardan shaft in rotational communication with the ring gear and configured to transfer the output torque; and a rear drive unit coupled to the cardan shaft and configured to selectively transfer the output torque received from the cardan shaft to a rear driveshaft of the vehicle, wherein the rear drive unit includes a torque shaft that is driven by the output torque received from the cardan shaft, and a second clutch that is configured to selectively transfer the output torque from the torque shaft to the rear driveshaft when activated.
