ABSTRACT:
A one-way clutch assembly positioned between inner and outer races for the clutch and which includes a one-piece generally cylindrical cage formed of a suitable plastic material having a plurality of openings to receive sprags therein, and a pair of integral spring fingers in each opening to engage the opposite sides of a sprag and lightly urge the sprag into contact with the interior and exterior surfaces of the inner and outer races of the clutch. To provide a full-phased sprag clutch, an additional cage ring is provided concentric to and closely fitting the cage with a plurality of openings generally aligned with the cage openings to provide a full-phased clutch operation. Further, a separate metal spring member can be substituted for the integral spring fingers, which spring member clamps onto a cross piece of the cage and provides spring fingers extending into the cage opening to contact the sprag.
