ABSTRACT:
An improved clutch shift mechanism for use with a motor vehicle transfer case. A cylindrical drive shell is concentrically positioned around a shaft axis in spaced relation to a relatively rotatable coaxial coupling member formed with external spline teeth. A plurality of axially directed circumferentially spaced slots are provided in the drive shell with each slot receiving a rocker key having an internal spline tooth at each ends of its inner face. The interior of the drive shell has grooves sized to capture therein a center and side annular springs. Each rocker key inner surface has a center notch and side notches receiving their associated springs therein with the key in its neutral position. An axially slidable shift ring surrounds the shell and includes an annular cam surface engaging a central depression in each key. Upon the shift ring being moved axially, each key is pivoted about the central spring causing the side spring to be compressed until each rocker key tooth drivingly engages a coupling members external spines. The side spring is operative to resiliently bias each rocker key one end to its neutral position upon the shaft ring being returned to its centered neutral position.
