Abstract
A transfer case includes first and second output shafts selectively driven by an input shaft. A first gearset is driven by the input shaft providing first and second gear ratios to the first output shaft. A range actuator includes an axially moveable member operable to shift the first gearset between the first and second gear ratios. An actuation shaft is coupled to the axially moveable member such that rotation of the actuation shaft translates the axially moveable member. A second gearset is driven by the input shaft and drives the actuation shaft. The second gearset includes a control gear moveable into and out of meshed engagement with a first gear and an idler gear. The actuation shaft is rotated in a first direction when the control gear is meshed with the first gear and rotated in an opposite direction when meshed with the idler gear.
