ABSTRACT:
A clutch mechanism of the rocker-shift type has a carrier member interposed between and affixed to one of a rotatable driving and a rotatable driven member. The carrier member has circumferentially spaced rocker arms, having normally self-disengaging clutch portions, that are adapted to be rocked radially, on at least one end thereof, by means of a shift yoke and collar, for selective rocking engagement into coupling engagement with adjacent corresponding normally self-disengaging clutch portions on the other of the driving and driven members. The collar has locked neutral and locked engaged positions on the carrier, with the improvement comprising means for axially shifting the collar to an unlocked engaged position intermediate the locked neutral and locked engaged positions and yieldingly maintaining the collar in this unlocked engaged position at a predetermined torque level, with the collar being axially shifted back into locked neutral position as result of the separation of the self-disengaging clutch portions when the predetermined torque level is exceeded by the torque transfer between the driving and driven members.
