Abstract:
A radial bi-directional overrunning clutch assembly, comprising:a driving member with first and second sets of radially-outwardly-biased pawls, the sets of driving member pawls each having at least one pawl, the driving member being rotatable in a first direction and a second direction; a reversing ring radially outward of the driving member pawls; a driven member having notches that are radially outward of the driving member pawls, the notches being selectively engagable with the driving member pawls; and a housing at least partially containing the driving member, reversing ring, and driven member, wherein the reversing ring is rotatable a limited number of degrees relative to the driving member between a first position and a second position, means, at least partially carried by the housing, for actuating the rotation of the reversing ring relative to the driving member, when the reversing ring is in the first position, the first set of driving member pawls is activated and the second set of driving member pawls is deactivated, at least one pawl of the first set of driving member pawls engaging one of the notches in the driven member when the driving member overspeeds the driven member in the first direction of rotation, and when the reversing ring is in the second position, the second set of driving member pawls is activated and the first set of driving member pawls is deactivated, at least one pawl of the second set of driving member pawls engaging one of the notches in the driven member when the driving member overspeeds the driven member in the second direction of rotation.
