Abstract
A planar inertia-actuated overrunning coupling assembly having a pocket plate and a notch plate mounted on a common rotary axis with planar juxtaposed coupling surfaces. A pocket plate having a plurality of angularly spaced pockets that receive adjustable clutch elements, the notch plate having angularly spaced notches, a clutch element being mounted in each pocket for pivotal movement about one edge thereof, an inertia-actuated ball in each pocket adjacent a clutch element, the pocket being formed with a ramp surface engageable with the inertiaactuated ball whereby the clutch element is shifted into locking engagement with the pocket plate in response to an inertia force acting on the actuator balls whereby torque is transmitted from one plate to the other in one direction of relative rotation of the plates, and wherein the clutch elements move out of registry with the pocket plate upon a reversal in the direction of relative rotation of the plates.
