ABSTRACT:
A transfer case for selectively providing four-wheel drive for a motor vehicle comprises a first clutch for shifting the input torque to and between a high speed power path, a low speed power path and a neutral position, as well as a second clutch for selectively engaging first and second output shafts for connection with the low and high speed power paths. Each clutch includes a slidable collar which is aligned with and slidable along the axis of the input shaft of the transfer case. Preferably, a single selector is used to shift the first and second clutch collars to provide the transfer case with four operating modes: a neutral position in which the input shaft is disengaged from the first and second output shafts, a two-wheel drive high speed output, a four-wheel drive high speed output and a four wheel drive low speed output.
