Abstract
An actuator system for a two-way overrunning roller clutch system includes a resilient torque transfer element which couples a wheel spindle and an aactuator ring. The torque transfer element minimizes potential damage due to misalignment between actuator and spindle parts. The actuator ring is banded by coiled garter springs to provide for frictional resilient engagement thereof with a clutch friction ring, the latter having its external circumference in mating contact with the internal circumference of the actuator ring. The degree of friction between the actuator and friction rings is controlled by garter spring tension to produce desired clutch actuation response.
Claims10
In a roller clutch system for driving a wheel hub about a wheel spindle, said system including a cage containing a plurality of rollers circumferentially spaced about the wheel spindle, said cage positioned intermediate of said spindle and said wheel hub, said cage including a friction ring and an actuator ring in resilient frictional engagement with said friction ring;
- an improvement comprising a torque transfer ring resiliently coupling said actuator ring to said spindle, and means for frictionally biasing said actuator ring against said friction ring.
