Abstract
Provided is a transfer case having an integrated planetary gear assembly is operably installed between an input member and first and second output members and constructed in a compact dual-planetary arrangement having dual sun gears and dual planet gears that are journally supported from a carrier. The planetary gear assembly is axially slidable relative to the input and output members to a number of positions for establishing various drive modes. Included among the drive modes is a two-wheel with on-demand four-wheel drive high-range mode. In this arrangement, the carrier is driven by the input member, and the first output is engaged with the carrier for providing two-wheel drive output. The carrier is further coupled to the input member of a torque coupling device. The torque coupling device is operable to sense relative rotation between the first and second output members and to deliver torque to the second output member in response to a loss of traction at the first output member.
