Abstract:
1. A bi-directional overrunning clutch, comprising: a housing; a driven shaft extending into said housing and disposed about a rotational axis; a first cam disc disposed about said driven shaft and defining a first inner race; a first outer race disposed about said driven shaft radially outwardly from said first cam disc; a first plurality of rollers disposed between said first cam disc and said first outer race; a second cam disc disposed about said driven shaft and defining a second inner race, said second cam disc axially spaced from said first cam disc; a second outer race disposed about said driven shaft radially outwardly from said second cam disc; and, a second plurality of rollers disposed between said second cam disc and said second outer race; wherein rotation of said driven shaft in a first rotational direction always causes rotation of said first outer race in said first rotational direction and freewheeling of said second outer race and rotation of said driven shaft in a second rotational direction, opposite said first rotational direction, always causes rotation of said second outer race in said second rotational direction and freewheeling of said first outer race.
