Abstract: A vehicle power steering assembly includes a housing, a ball nut configured to be operatively disposed in the housing and including an extension portion provided with a convex bearing surface, an insert supported on the housing and provided with a concave bearing surface. The concave bearing surface is complementary to the convex bearing surface. The convex and concave bearing surfaces are a plain bearing configured to provide sliding movement relative to each other. The sliding movement provides relative rotation between the convex and concave bearing surfaces in a first direction on the ball nut axis and a second direction on a rotation axis that is transverse to the ball nut axis.

Abstract: A power steering assembly has a housing and a ball nut assembly supported on the housing. The ball nut assembly has a ball nut axis. The housing has a first surface between the housing and the ball nut assembly. The ball nut assembly also has a second surface. The second surface rotates on the first surface such that the ball nut assembly rotates relative to the housing on a rotation axis that is transverse to the ball nut axis.

Abstract: A rack drive assembly adapted for use in the vehicle electric power steering assembly includes a steering member operatively connected to a vehicle steering wheel; an electric motor for effecting axial movement of the steering member upon rotation of the vehicle steering wheel; a planetary gear assembly operatively coupled to the electric motor; and a pinion assembly operatively disposed between the planetary gear assembly and the steering member whereby operation of the electric motor is operative to effect axial movement of the steering member, wherein the electric motor includes an output shaft which defines a motor axis and the pinion assembly includes an output shaft which defines a pinion axis, wherein the pinion axis is coaxial with the motor axis and perpendicular with respect to an axis of the steering member.

Abstract: A rack drive assembly adapted for use in a vehicle electric power steering assembly includes a bearing assembly disposed in a rack housing and carried by a ball nut assembly for rotatably supporting the ball nut assembly relative to a steering member; and a spanner nut carried by the rack housing for securing the bearing assembly in the rack housing. A first isolator, a second isolator and a first shim are provided wherein the first isolator is disposed between an inner surface of the housing and a first surface of an outer race of the bearing, the second isolator is disposed between an opposite second surface of the outer race of said bearing and the first shim, the first shim is disposed between the second isolator and the spanner nut. The first shim is provided with a member configured to be coupled to the housing to allow for axial movement but prevent rotational motion of the shim during installation of the spanner nut.

Abstract: A toe link assembly of a suspension system includes a cam sleeve having a first and second end, a first cam plate fixedly attached to the cam sleeve at the first end, and a second cam plate fixedly attached to the cam sleeve at the second end. In addition, the toe link assembly includes a first cam washer rotatably received by the first cam plate, a second cam washer rotatably received by the second cam plate, and a bolt having a head fixedly attached to the first cam washer, a body extending between the first and second ends of the cam sleeve, and a shank fixed for rotation with the second cam washer. Rotation of the bolt causes the first and second cam washers to react against the first and second cam plates to position the bolt relative to the cam sleeve along a first longitudinal axis.

Abstract: A mounting system for a vehicle steering system is provided. The mounting system includes a bushing, an isolator and a fastener. The bushing includes a retaining flange and a threaded internal cavity. The isolator includes a hollow body portion and a first end wall. The isolator is installed to a steering gear assembly such that the inner surface of the end wall contacts one surface of the steering gear housing. The bushing is installed through the isolator such that the retaining flange contacts an outer surface of one of the end walls. The steering gear assembly is positioned against a vehicle chassis such that the exterior surface of the other end wall contacts a structural member. The fastener is installed through the structural member and threadably engages the internally threaded cavity. The bushing limits the amount of clamping force transmitted to the end walls and permits the isolator to effectively dampen noise and vibration.
