Abstract

A transfer case includes an input shaft and first and second output shafts. An overdrive unit is driven at an increased speed relative to the input shaft. A clutch is operable in a first position to establish a drive connection between the input shaft and the first output shaft. The clutch is further operable in a second position to establish a drive connection between the overdrive unit and the first output shaft. An actuator is driven by a motor for moving the clutch between its first and second positions. The actuator includes an axially movable fixed disk fixed for rotation with an output member of the overdrive unit. The shift engages an axially movable sleeve of the clutch.
