Abstract
A transfer case includes a primary output shaft, and a secondary output selectively coupleable to the primary output shaft with a secondary torque transfer mechanism. The secondary torque transfer mechanism comprises a plate clutch and a locking sleeve. The plate clutch includes a housing coupled to the secondary output shaft, a plurality of interleaved plates alternatingly coupled to the primary output shaft and the housing, and an apply plate coupled to the primary output shaft and being configured to compress the interleaved plates to selectively form a friction coupling between the primary output shaft and the secondary output shaft. The locking sleeve is non-selectively coupled to one of the housing or the apply plate to rotate therewith, and is selectively coupleable to the other of the housing or the apply plate to form a positive coupling between the primary output shaft and the secondary output shaft.
