Abstract
An actuator assembly configured to control the movement of a stabilizer includes a ball screw having a longitudinal axis and configured to be rotated by a drive assembly, a primary nut assembly coupled to the stabilizer and received on the ball screw such that rotation of the ball screw causes movement of the primary nut assembly along the longitudinal axis of the ball screw, the ball screw and primary nut defining a primary load path between the between the drive means and the stabilizer, and a secondary nut assembly coupled to the primary nut assembly and configured to engage the ball screw upon failure of the primary load path. The secondary nut assembly comprising a split nut assembly having opposing halves extending about the ball screw, the split nut having at least one outer cam surface along the outer surface of one of the halves; and a secondary nut housing extending about the split nut; wherein upon failure of the primary load path, rotation of the outer cam surface is configured to move the split nut into locking engagement with the ball screw.
