Abstract: An improved one-way clutch includes an outer race having an annular inner surface, an inner race having an annular outer surface disposed coaxially with the outer race, a plurality of sprags spaced circumferentially between the inner surface and outer surface, a sprag holder for holding the sprags in an annular space between the annular surfaces and a plurality of inertia resistance members having an arcuately conforming engagement surface mounted about the sprag holder, the arcuately conforming engagement surface being in engagement with one of the said inner surface and outer surface to provide torque resistant drag between the sprag holder and one of the inner and outer surfaces.

Abstract: A one-way roller clutch has an inner race, an outer race, a plurality of rollers that are disposed between the races and a cage assembly that is keyed to the outer race. The cage assembly anchors a plurality of energizing springs that bias the rollers toward an engaged position where the rollers are wedged between the races so that one race drives the other. The energizing springs are variable rate springs that produce exponentially increasing spring forces that counteract the centrifugal force of the rollers so as to reduce roller displacement during overrunning and response time for clutch engagement for all operating speeds of the one-way roller clutch.

Abstract: A one-way sprag clutch assembly for use in an automatic transmission or slar application including an inner race (42), an outer race (44) having a pair of annular grooves (63, 68) cut in the interior surface (45) thereof, and a clutch assembly (41) having an inner cage member (46), an outer cage member (53) and an intermediate energizing spring (49), the cage members and spring having generally aligned openings (47, 51, 55) for receiving a plurality of sprags (48) therein. A side wall (56) is integrally formed with and perpendicular to the outer annular cage member (53) to create, with an end cap (64) on the opposite end of the assembly, lubrication escape barriers for lubricant in the assembly.
