ABSTRACT:
A manually operated change-speed mechanism in a power transfer device includes input and output shafts arranged coaxially to each other for relative rotation, a planetary gear unit mounted on the input shaft and having an input element mounted on the input shaft for rotation therewith and an output element connectable to the output shaft, an internally splined clutch sleeve axially slidably mounted on an externally splined portion of the output shaft and shiftable between a first position in which it is engaged with the output element of the gear unit and a second position in which it is engaged with an externally splined portion of the input shaft, wherein a synchronizer assembly is arranged to effect synchronous engagement between the clutch sleeve and the externally splined portion of the input shaft in shifting operation of the clutch sleeve toward the second position.
