Abstract

A two speed transfer case includes a spring biased dog clutch connecting a shift sleeve to a main input shaft and an electromagnetic friction clutch for transferring torque from the shift sleeve to one of the outputs. This arrangement allows dynamic upshifts and downshifts and modulation of the torque split between the outputs.
