摘要： An improved structure for a rack drive assembly adapted for use in a vehicle electric power steering assembly includes a ball nut assembly operatively connected to a screw portion of a rack portion of a steering member of the power steering assembly for effecting axial movement of the steering member upon rotation of a vehicle steering wheel. According to one embodiment, the ball nut assembly includes a ball nut having an outer surface; a bearing assembly fixedly disposed in the rack housing and carried by the ball nut for rotatably supporting the ball nut assembly relative to the steering member; and a damper disposed on an outer race of the bearing assembly. The damper includes a pair of dampers disposed on the outer race of the bearing assembly, each of the dampers including at least a first member formed from a first rigid material and a second member formed from a second damping material.

摘要： This invention relates to a ball joint assembly adapted for use in a motor vehicle. The ball joint assembly includes a housing (12) defining socket chamber (18) and having an opening (32); a composite ball joint bearing (20) disposed within the socket chamber; a ball stud (24) supported by the composite ball joint bearing and having a shank portion (30) which projects through the opening of the housing; and a seal assembly (40) adapted to seal the opening between the ball stud and the socket chamber. According to the present invention, the composite ball joint bearing is formed from a first plastic material (20A) and a second magnetostrictive alloy material (20B) which is adapted to change its shape when in the presence of a magnetic field to thereby change the rotational and oscillation properties of the ball joint assembly.
