Abstract
An overrunning coupling assembly includes a notch plate and an annular coupling pocket plate positioned in face-to-face relationship with respect to each other along a common axis. The pocket plate has strut pockets disposed at angularly spaced positions about the common axis. The notch plate has notch recesses at angularly spaced positions about the common axis and positioned in juxtaposed relationship with respect to the strut pockets. Torque-transmitting struts are positioned in each of the strut pockets. Each strut has first and second ears at one edge thereof for enabling pivotal motion of the struts about an ear axis intersecting the ears. The opposite edge of each strut is movable between disengaged and engaged positions with respect to one of the notch recesses whereby one-way torque transfer may occur between the plates. A lubricant flows between the notch plate and pocket plate. A spring is positioned in each strut pocket and biases the respective strut toward the notch plate. Each spring engages the respective strut intermediate the ear axis and the opposite edge. Each strut pocket provides sufficient clearance forward of the respective opposite edge of the strut to allo…
