Abstract
A switchable one-way clutch includes an outer race, an inner race, a plurality of rollers, and a drag plate. The outer race has a ramped inner surface. The rollers are contactable with the outer race and the inner race. The cage is for positioning the plurality of rollers. The drag plate is rotationally engaged with the cage and frictionally engageable with the inner race. In an example embodiment, the cage has a notch and the drag plate has a tab installed in the notch to engage the drag plate to the cage. In an example embodiment, the drag plate or the inner race includes a friction material ring bonded thereto for increasing a friction coefficient between the drag plate and the inner race. In an example embodiment, the clutch has an arc spring. The outer race includes a pocket, the cage includes a tab, and the arc spring contacts the pocket and the tab to displace the cage in a first rotational direction. In an example embodiment, the inner race includes an inner splined surface.
