Abstract

A one-way clutch assembly comprises an outer race, first and second inner races rotatable about an axis, a first and a second plurality of rocker members, and first and second cages. The outer race has a plurality of pockets defined in an inner surface. First and second inner races are aligned axially side-by-side and each include rocker teeth defined on an outer surface. One rocker member from the first and second plurality of rocker members is disposed in each pocket of the outer race. The first plurality of rocker members are arranged to face in a first direction and the second plurality of rocker members are arranged to face in a second, opposite direction. First and second cages are positioned radially between the inner and outer races and configured to selectively displace the first and second plurality of rocker members, respectively, between disengaged and engaged positions.
