ABSTRACT:
A transfer device associated with a power transmission unit includes an input shaft for connection to an output shaft of the transmission unit, a first output shaft axially aligned with the input shaft through an intermediate shaft, a second output shaft located parallelly apart from the input and intermediate shafts, a selector gear unit associated with a change-speed gearing for selectively completing low and high speed gear trains, and a differential gear unit mounted on the intermediate shaft for distributing drive power to the first and second output shafts. In the change-speed gearing, a high speed drive gear is connected with an output member of the differential gear unit and in mesh with a high speed counter-gear to provide a power path between the differential gear unit and the second output shaft, and a second selector gear unit is assembled adjacent to the first-named selector gear unit on a common axis to control the operation of the differential gear unit.
