Abstract:
A vehicle transfer case is provided including input and output shafts mounted within a housing, a secondary shaft selectively driven by the output shaft, a first hub having an inner diameter splined section having a first extreme neutral position with exclusive torsional engagement with the output shaft, and in a second intermediate high position having torsional engagement with the output shaft and input shafts, and in a third extreme low position having exclusive torsional engagement with the input shaft. A second hub is provided, rotatably mounted on the first hub and axially fixed therewith. The second hub is torsionally fixed to the output shaft, and a shift fork is provided to translate the second hub. A planetary gear set is provided, having a ring gear, a plurality of planet gears connected to each other by a carrier and a sun gear; and wherein in the extreme neutral position the output shaft is disengaged from the input shaft, and in the second intermediate position the input shaft is directly connected to the output shaft without rotating the planetary gear set, and in the extreme third position the first hub torsionally connects the input shaft to the sun gear, and the second hub is connected with the carrier.
