ABSTRACT:
An overrunning clutch device including a thrust ring slidably fitted in the driven clutch member and held connected with the driving clutch member and a set of spherical centrifugal weights mounted on respective radially flexible resilient arms of a weight retainer, which is fixed to the driven clutch member integral with a drive pinion. The centrifugal weights are held in rolling contact with a tapered annular guide surface of the thrust ring and act to force the latter and hence the driving clutch member away from the driven clutch member under centrifugal force when their speed of rotation exceeds a predetermined level.
