Abstract: An electric powered steering assembly comprises a housing with a cylindrical portion, an interior wall of the cylindrical portion defining a first and second grooves extending in an axial direction, the first and second grooves having inwardly tapered walls. A ball screw is disposed in the housing, extending in the axial direction, and defining a through hole extending in a radial direction having a first and second ends. A ball nut is disposed in the housing surrounding the ball screw and configured to rotate relative to the housing. A first anti-rotational pin is disposed in the first end of the through hole, a second anti-rotational pin is situated in the second end of the through hole, and a spring is disposed between the anti-rotational pins. The spring is configured to bias the first and second anti-rotational pins in a radially outward direction towards the first and the second groves respectively.

Abstract: A steering system is provided. The steering system includes a housing and a ball shaft translatable relative to the housing. A ball nut is rotatably mounted within the housing. Rotation of the ball nut responsively causes the ball shaft to translate relative to the ball nut and the housing. The ball shaft has an opening extending therethrough. A pin is separate from the ball shaft and inserted into the opening. The pin engages the housing to limit rotation of the ball shaft relative to the housing.
