Abstract: A ball-screw assembly isolator is provided and includes a housing, a ball-screw, a ball-screw nut, a bearing assembly, a retaining member, a second retaining member, a first compressible member and a second compressible member. The bearing assembly is located between the housing and the ball-screw. The bearing assembly includes an inner race and an outer race. The retaining member is secured by the housing. The second retaining member is secured to the ball-screw nut. The first compressible member positioned between the housing and the outer race. The second compressible member is positioned between the outer race and the retaining member. The retaining member is configured to be preloaded to exert an axial force upon the first compressible member and the second compressible member.

Abstract: In an embodiment of the invention, an end of travel stop is provided for a steering gear assembly having a housing, a rack, and a tie rod. The end of travel stop includes an annular body comprising a plurality of segments defining a first crenellated side of the annular body and a second crenellated side of the annular body. The stop is circumscribed over the rack and is oriented between the housing and the tie rod, and is configured to absorb an impact force transferred through the tie rod and to prevent overtravel of the rack.

Abstract: A rotary-to-linear mechanism including an elongate linearly-moveable first member having a longitudinal first axis, and rotatably-moveable second and third members. The second member is rotatably disposed about the first member and defines a second axis about which it is rotatable. The third member encircles the first axis and is operatively engaged with the first member. The third member is disposed in a central cavity of the second member and has an axial surface superposing a second member interior surface, the superposed surfaces each defining one of a pair of corresponding grooves each encircling the first and second axes.

Abstract: Automotive front end structure adapted to be mounted on an automotive vehicle frame to absorb impact energy. The structure includes first and second crush hoops each having a central portion and side portions extending rearwardly from the central portion. The rear ends of the side portions of each hoop are connected to brackets and then to first and second crush boxes. Brackets connect the crush boxes to the vehicle frame. The crush hoops and the crush boxes are adapted to crush and collapse to absorb energy in a frontal impact. The central portion of the first crush hoop projects forwardly a greater distance than the central portion of the second crush hoop so that the first crush hoop is first to deform in a front impact. Thereafter, the other hoop begins to load and dissipate energy to provide a smooth, continuous and progressive reaction force to front end deformation.

Abstract: A torque box assembly for mounting between a vehicle frame side rail and a body side sill for supporting a rear suspension trailing link. The torque box assembly includes two interconnected box members and two mounting flanges, with the trailing link resiliently connected to one of the box members.
