Abstract
A multi-directional coupling includes a housing which incorporates a first bearing surface, a race which incorporates a second bearing surface opposite the first bearing surface, a plurality of roller elements, and an alignment cage. The first bearing surface and the second bearing surface together define a channel therebetween for receiving the roller elements. The first bearing surface includes at least one recessed bearing surface portion which is configured for receiving one of the roller elements therein for coupling the housing with the race as the one roller element moves relative to the housing. The alignment cage is disposed within the channel for controlling the spacing between the roller elements. The multi-directional coupling also includes a mode controller coupled to the alignment cage for controlling the relative movement of the one roller element so as to alter the coupling mode of the coupling.
