ABSTRACT:
This invention relates to an improved automatic four-wheel drive clutch of the type forming the subject matter of my copending application U.S. Ser. No. 180,699, now U.S. Pat. No. 4,369,868, but differing therefrom in that instead of employing axially-spaced toothed cam surfaces with toothed cam followers forming an operative connection therebetween effective upon relative rotation to move a drive member into and out of driving engagement with a driven element, circumferentially-spaced coaxial cam rings carrying opposed pairs of overlapped oppositely opening generally V-shaped track-forming grooves operatively interconnected by a single ball between each pair is used to shift the drive element axially between its engaged and disengaged positions.
