  • Publication number: 20120061164
    Abstract: Disclosed is a power steering system for a motor vehicle, comprising a housing in which a steering rod is held in an axially movable manner. The steering rod comprises a spindle section which, together with a rotatably mounted recirculating ball nut forms a recirculating ball screw and nut gear. A support bushing is provided between an axial end of the steering rod and the recirculating ball nut, the bushing providing a through-hole for guiding the steering rod through. The inner face of the support bushing which faces the steering rod has a curved contour so that the opening cross-section of the through-hole increases toward the end of the steering rod. The curved contour is adapted to a bending line of the steering rod so that the steering rod, when it comes in contact with the support bushing as a result of a bending load, abuts the curved contour thereof in a planar manner.
