ABSTRACT:
A two-speed transfer case includes an input shaft that is driven by a vehicle engine, a first output shaft that is coupled to a rear axle, and a second output shaft that is coupled to a front axle. The transfer case also includes a high range gear set and a low range gear set. The high range gear set includes a first gear supported on the input shaft and a second gear supported on the first output shaft. The low range gear set includes a third gear supported on the input shaft and a fourth gear supported on the second output shaft. A shifting mechanism cooperates with the second and fourth gears and the first and second output shafts to provide a plurality of operational output configurations. The shifting mechanism is integrated into a housing that substantially encloses the input shaft and the first and second output shafts.
