Abstract
A one-way clutch, including: pocket and inner rings; rollers between the rings; springs urging the rollers in a first circumferential direction; a switch ring including protrusions in contact with the rollers and having ramps. In a one-way configuration: the inner and pocket rings non-rotatably connect for relative rotation of the inner ring, with respect to the pocket ring, in the first circumferential direction; and for a free-wheel mode, the inner ring is rotatable in a second circumferential direction with respect to the pocket ring. In an open configuration: the inner and pocket rings are independently rotatable. To transition from the one-way clutch configuration to the open configuration: the actuator axially displaces the switch ring with respect to the pocket ring; the ramps slide along the pocket ring to rotate the switch ring in the second circumferential direction; and the protrusions displace the rollers in the second circumferential direction.
