An apparatus for a vehicle is provided that includes an axle with a keyway. A spindle sleeve is present that has a spindle sleeve inner surface axis coaxial with the axis of the axle. A spindle sleeve outer surface axis is not coaxial with the axis of the axle, and the spindle sleeve has a sleeve washer that has a keyway tab. A retaining nut is in selective rotating communication with the sleeve washer such that rotation of the retaining nut is communicated to the sleeve washer to cause the spindle sleeve to rotate relative to the axle when the retaining nut is in rotating communication with the sleeve washer. Rotation of the retaining nut is not communicated to the sleeve washer to cause the spindle sleeve to rotate relative to the axle when the retaining nut is not in rotating communication with the sleeve washer.

A vehicle floating disc hub assembly includes a hub portion that includes a bearing housing provided on an inner circumferential surface such that a bearing coupled to an axle is mounted, a flange portion provided in one end in an axial direction, and a plurality of disc fastening grooves provided in the other end; and a disc portion mounted on the hub portion having a hub fastener to be fastened to the disc fastening groove through a fastening member corresponding to the disc fastening groove. The fastening member includes a spring clip mounted between the disc fastening groove and the hub fastener to form a contact force therewith, a spring plate formed to have an elastic force in the axial direction of the axle and placed in the spring clip, and a fastening bolt that couple to the hub fastener through the spring plate.

A wheel bearing assembly includes at least two rolling-element bearings which participate together in a bearing assembly. At least one of the rolling-element bearings includes at least one bearing ring, which, for transmitting a propulsion, is attached to a drive shaft . At least one brake element of the wheel bearing assembly is immovable relative to the bearing ring and a connecting unit of the wheel bearing assembly connects the brake element to the bearing ring. By a removal of the connecting element from the bearing ring in which none of the rolling-element bearings need to be removed, even only partially, the brake element is removable from the rolling-element bearings and is displaceable to any distance from the bearing ring.

In a vehicle suspension assembly a sensorized system applied to a wheel hub unit, in which radially outer cylindrical surface of an outer ring of the wheel hub unit configured for coupling to a suspension upright or knuckle has four circumferential flats formed to be angularly spaced from each other on the radially outer lateral cylindrical surface, each flat delimiting a plane surface which extends axially over a pair of annular tracks for rolling bodies of the outer ring; each flat carries integrally a sensor module including a pair of extensometers positioned parallel to each other and each at the position of a respective annular track, orientated in a circumferential direction so as to extend along a circumferential development of the annular track; an electrical circuit picks up a signal from each sensor module and sends it to a data socket carried by the suspension upright or knuckle.

A wheel hub bearing for motor vehicles providing a hub and a bearing unit in turn comprising a radially outer ring, at least one radially inner ring, at least one crown of rolling bodies between the radially outer ring and the radially inner ring. The hub has a radial stiffening. The radial stiffening of the hub has a misalignment respect to a seat. Accordingly, a distance between a centerline axis of the seat of the radially inner ring on the hub and a center line of the radial stiffening, less than or equal to 25% of a length of the seat.

A wheel hub bearing for motor vehicles including a rotatable hub provided with a flange for the engagement of the hub to a wheel of a vehicle and provided with a radially outer free portion and a bearing unit provided with a radially outer ring for the engagement of the wheel hub bearing to a knuckle of the vehicle and a radially inner rotatable ring angularly connected to the hub. Furthermore, the wheel hub bearing has a device for detecting a vehicle parameter and provided with an encoder and a sensor in communication with the encoder. The encoder is ridgidly coupled to the radially outer free portion of the flange to jointly rotate with the hub.

A bearingless hub assembly comprising a rim hollowed to receive a tube magnet, and magnets embedded around the circumference of the rim on both ends. The rim is capped by front and rear rim plates configured to hold the embedded magnets in place and fitted to receive respective circular magnets. Similar magnets in corresponding front or rear drive plate maintain space (i.e., levitation) vis-à-vis the front and rear rim caps by repelling each other, thus allowing the rim (and, as applied, a mechanically-attached tire assembly) to move freely with no friction. The front and rear drive plate carry forward and reverse electromagnetic actuators as well as forward and reverse levitation control units, power generators and speed sensors. These components mount 360 degrees around the circumference of the drive plates while the embedded magnets of the rim spin through when in motion.

The rotational torque inspection method for a bearing device comprises: a press-fitting step (S02); a first bearing preload value calculation step (S03) for calculating a first bearing preload value (P1); a post-press-fit rotational torque measurement step (S05) for measuring a post-press-fit rotational torque (Ta); a crimping step (S06) for crimping the small diameter step part to the inner ring; a post-crimping rotational torque measurement step (S07) for measuring a post-crimping rotational torque (Tb); a second bearing preload value calculation step (S08) for calculating a second bearing preload value (P2); and a determination step (S09) for determining the suitability of the preload depending on whether or not the second bearing preload value (P2) is within a range of a reference value.

An in-wheel motor drive device (10) includes a wheel hub bearing unit (11) having an outer ring (13), an inner ring (12) protruding from the outer ring to one side in an axial (O) direction, rolling elements (14) between the outer ring and the inner ring, and a fixing bolt (15) for fixing the outer ring to a non-rotary member (102); and a brake disk (55) having a connecting portion (58) configured to connect with one end of the inner ring, a cylindrical portion (57) extending from the connecting portion to the other side in the axial direction and disposed coaxially to the inner ring, and at least a part of the fixing bolt is received in an internal space of the cylindrical portion.

A suspension upright assembly for a vehicle provides a wheel hub bearing and a suspension upright including a fiber-reinforced composite bushing arranged around the wheel hub bearing, attachment members for attaching the suspension upright to a suspension assembly and to a brake caliper of the vehicle, and a fiber-reinforced composite truss-structure that connects at least one of the attachment members to the bushing and/or to a further one of the attachment members.
