Abstract

The present invention relates to a bi-directional overrunning clutch that enables movement of an object between multiple rotational bodies in either direction using a single motor. The clutch includes a pair of cam discs disposed about a driven shaft extending from the motor and spaced from one another, outer races disposed outwardly of each cam disc and rollers disposed between the cam discs and outer races. The cam discs are oriented such that rotation of the shaft in one rotation direction causes rotation of one outer race and freewheeling of the other outer race while rotation of the shaft in the opposite rotational direction causes rotation of the other outer face and freewheeling of the one outer race.
