<p>An actuator includes a housing assembly (112), a ball nut (104), a ball screw (106), and a ball screw stop (120). The ball nut (104) is rotationally mounted in the housing assembly, is adapted to receive an input torque, and is configured, upon receipt thereof, to rotate and supply a drive force. The ball screw (106) is mounted within the housing assembly and extends through the ball nut. The ball screw has a first end and a second end, and is coupled to receive the drive force from the ball nut. The ball screw (106) is configured, upon receipt of the drive force, to selectively translate between a stow position and a deploy position. The ball screw stop (120) is mounted on the ball screw (106) to translate therewith and is configured to at selectively engage the housing assembly (112) while the ball screw is translating, and engage the ball nut when the ball screw is in the deploy position.</p> |
