Abstract
An actuator assembly for selectively actuating a clutch includes a first actuator ring that is moveable between a first axial position and a second axial position along a rotational axis of the clutch, and a second actuator ring that is slidably received within the first actuator ring, and that is moveable between a third axial position and a fourth axial position by the first actuator ring. The first actuator ring receives a first actuation force, and when in the second axial position, transfers the first actuation force to the second actuator ring. The second actuator ring selectively receives the first actuation force and a second actuation force, and when in the fourth axial position, transfers one of the first and second actuation forces to the clutch. The actuator assembly is included with a transmission and actuates a clutch that provides an input to a planetary gear set of the transmission.
