Abstract
An overrunning clutch assembly including first and second ring-shaped clutch members with face surfaces disposed in opposing relation and with at least one rigid strut disposed therebetween for movement to engage recessed pockets in the opposed surfaces upon rotation in one direction and for movement out of engagement with the pockets in at least one of the face surfaces upon relative rotation in the opposite direction. A retaining member permanently retains the clutch in assembled relation and cooperates with the ring-shaped clutch members to form a lubricant reservoir maintaining the struts in a lubricant bath during operation. The retaining member forms a weir over which the lubricant flows from the reservoir at a radial location to assure that the struts remain submerged during operation.
