Abstract
A switchable clutch includes an outer ring, an inner ring, a roller cage, a plurality of rollers, and a drag plate. The outer ring includes a plurality of ramped surfaces. The roller cage is disposed radially between the outer ring and the inner ring. The rollers are guided by the roller cage. The drag plate is rotationally fixed to the inner ring and is engageable with the roller cage to rotate the rollers relative to the outer ring. In an example embodiment, the switchable clutch has a spring engaged with the outer ring for urging the roller cage in a first rotational direction relative to the outer ring. In an example embodiment, the switchable clutch has an electromagnet for engaging the drag plate and the roller cage and/or a coil spring assembly for disengaging the drag plate and the roller cage.
