A transfer case for use in a motor vehicle to selectively transfer drive
torque from a powertrain to first and second pairs of wheels. The
transfer case includes an input shaft driven by the powertrain and an
output shaft selectively driven by the input shaft. A transfer mechanism
is operably disposed between the input shaft and the output shaft to
transfer drive torque from the input shaft to the output shaft. The
transfer mechanism includes a first chain that is selectively driven by
the input shaft and a second chain that is driven by the first chain and
that transfers drive torque to the output shaft.
