Abstract
A clutch assembly is provided that includes inner and outer races. The clutch assembly also includes sprags concentrically disposed in an annular space between the inner and outer races. Each sprag includes an inner step and an outer step. The clutch assembly further includes a segmented ring configured to radially expand and radially contract. The clutch assembly also includes a resilient element configured to exert a force on the segmented ring and affect expansion or contraction of the segmented ring. In a disengaged state, the segmented ring is configured to contract to exert a radially inward pressure on the inner step of each sprag to create a gap between each sprag and the outer race. In an engaged state, the segmented ring is configured to expand to exert radially outward pressure on the outer step of each sprag to wedge each sprag between the inner and outer races.
