ABSTRACT:
A SOWC for use with a vehicle transmission is provided. The clutch includes outer and inner elements, also referred to as races, with the latter oriented concentrically within the former about an axis of rotation. A selection mechanism, which may be annular plates operatively connected with the side of the races and with one another, is selectively rotatable with respect to the inner and outer elements between different positions. Pivotable rocker elements are positioned between the races and are movable along cammed slots of the annular plates when the annular plates are rotated to establish a forward, a reverse, and a neutral operating mode corresponding with the different positions of the annular plates. In some embodiments, in the neutral operating mode, none of the rocker elements are in contact with the inner race.
