Abstract: A drive device includes a first member including a first shoulder, and a second member positioned in close proximity to the first member and including a second shoulder. The device also includes a coupling arrangement including a strut having a first edge for direct engagement with the first shoulder, a second edge for engagement with the second shoulder and supported for pivotal movement between engaged and overrun positions, based on relative rotation of the first and second members such that the first member drives the second member in a drive mode with the strut in the engaged position and the first and second members can overrun with respect to one another with the strut in the overrun position. The coupling arrangement also includes a cushioning member disposed between the second edge and the second shoulder for cushioning each initial engagement of the strut in the drive mode.

Abstract: A one-way drive device includes a first, drive member rotatable about an axis in both a drive direction and an opposite, overrun direction. The one-way drive device also includes a second, driven member rotatable about the axis in at least a driven direction. The one-way drive device further includes a coupling arrangement including at least one strut cooperating with the first and second members such that the first member is able to drive the second member in the driven direction by causing the strut to initially engage and remain engaged between the first and second members during the time the first member drives the second member. In addition, the coupling arrangement includes a cushioning arrangement for cushioning the initial engagement of the strut between the first and second members.
