ABSTRACT:
The present invention provided a power transfer system for a four-wheel drive vehicle. The transfer system includes a part-time transfer case having an input member rotatably driven by the vehicle's engine, first and second output members operable to rotatively drive respective front and rear axle assemblies, and an intermediate shaft through which power is selectively transferred from the input member to one or both of the first and second output members. In operation, driven rotation of the intermediate shaft causes power to be constantly delivered to the first output member and the front axle assembly for establishing a two-wheel drive mode of operation. Moreover, selective actuation of a mode shift arrangement functions to interconnect the second output member to the intermediate shaft for also delivering power to the rear axle assembly for establishing a four-wheel drive mode of operation.
