Abstract: A self-locking nut and screw assembly may include a screw and a first nut rotatable and linearly translatable with respect to each other. The assembly may also include a first motor configured to provide torque to one of the screw and the first nut. The assembly may further include a locking mechanism configured to lock the screw to prevent backdrive when the motor is not providing torque to the one of the screw and the first nut.

Abstract: An actuator includes a drive assembly, a ball screw, and a ball nut. The ball nut may include a first nut member, a second nut member; and first arm extending from the first nut member. The first arm may include a first portion and a second portion. The first portion may extend radially outward from the first nut member. The second portion may extend substantially axially from the first portion such that at least some of the second portion is disposed radially outward of the second nut member. A second arm may extend from the second nut member, and the second arm may include a first portion and a second portion. In embodiments, at least part of the second portion of the first arm is disposed radially outward of at least a part of the second portion of the second arm.
