Abstract
A transfer case () and a method of assembly can include an input shaft () and output shafts (), a mode clutch () for shifting between a two-wheel and four-wheel drive mode, a mode shift mechanism (), a planetary gear assembly () for providing a different drive ratio between the input shaft () and the output shaft (), a range shift mechanism (), and a synchronizer () for speed synchronization before shifting between a low-range drive mode and a high-range drive mode. A fixed ring gear () can be connected to the planetary gear assembly () during the high-range and low-range drive mode. The mode shift mechanism () and the range shift mechanism () can be electro-mechanically actuated by a reversible rotatable actuating gear () interposed between an expandable clutch actuator () and a rotatable barrel cam ().
