Abstract
A shift synchronizer for a motor vehicle transfer case includes a pair of blocker rings disposed on opposite sides of a plurality of circumferentially arrayed struts. The blocker rings include respective symmetrically disposed cone clutch faces. The clutch faces abut complementarily configured surfaces on the input shaft and the planet carrier of a planetary gear speed reduction assembly. The struts are spring biased radially inwardly by circumferentially extending tension springs and are received upon and detentingly engage a shift sleeve. The shift sleeve is splined to the transfer case output shaft. As the shift sleeve is translated axially toward either the input shaft or the planet carrier, the cone clutch face of the respective blocker ring is urged into contact with its adjacent complementarily configured clutch surface thereby frictionally engaging the output shaft with the input shaft or the planet carrier thereby causing such components to achieve synchronism.
