ABSTRACT:
A power transfer device adapted for use in combination with a primary transmission for an automotive vehicle, including a housing, a first output shaft rotatably mounted on the housing and having an input end for drive connection to an output shaft of the power transmission and an output end for drive connection to a first set of road wheels, a second output shaft rotatably mounted within the housing in parallel with the first output shaft and having an output end for drive connection to a second set of road wheels, a drive member rotatably mounted on the first output shaft, a driven member mounted on the second output shaft for rotation therewith and being drivingly connected to the drive member, a center differential in the form of a planetary gear unit mounted on the first output shaft and having a first output element in drive connection to the first output shaft and a second output element for drive connection to the drive member, and a changeover mechanism arranged between the planetary gear unit and the drive member and mounted on the first output shaft to selectively connect the second output element of the planetary gear unit to the drive member.
