Abstract:
An overrunning coupling assembly comprising:a pocket plate and a notch plate, one plate being connected to a torque input member and the other plate being connected to a torque output member; the pocket plate having a pocket plate planar surface and the notch plate having a notch plate planar surface, the planar surfaces being assembled on a common axis in juxtaposed close proximity; a plurality of angularly-spaced pockets in the pocket plate planar surface; a plurality of angularly-spaced notches in the notch plate planar surface; a ramped surface in each pocket; a torque-transmitting strut in each pocket, each strut having an anchor edge engageable with the pocket plate and a movable edge engageable with a notch in the notch plate during operation of the overrunning coupling assembly in a locked mode; and inertia members having rounded roll surfaces in the pockets between the struts and the ramped surfaces whereby the inertia members urge the struts into engagement with notches in the notch plate in response to rotary inertia forces acting on the inertia members.
