Abstract
A two-way overrunning clutch is automatically conditioned for operation in either direction of rotation. A plurality of spaced drag springs are in frictional contact with the clutch housing so as to provide balanced radial drag forces on the wedging elements of the clutch, thereby biasing the clutch toward an engaged position thereof. This frictional contact with the clutch housing is reduced by balanced dynamic friction forces developed upon rotation of the clutch.
