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.

Abstract: An actuator includes a housing member configured for connection with a first component, a drive screw connected to the housing member, a rod disposed at least partially in the drive screw and at least partially in the housing member, a retaining nut connected to the rod, a mounting member configured for connection with the first component, and a drive nut engaged with the drive screw and configured for connection with a second component. If the drive screw mechanically disconnects or is fractured, the rod may be configured to translate to engage one or more friction surfaces to restrict back driving of the drive screw.
