A wheel rim assembly for a wheel of a motor vehicle may include a wheel rim and a cover portion arranged on an outside of the wheel rim. The cover portion may be guided on the wheel rim so as to be movable relative to the wheel rim between an open position allowing an air flow between the outside and an inside of the wheel rim, and a closed position preventing the air flow. Conversion from the open position to the closed position takes place automatically based on an operating state of the wheel. The cover portion may be configured as a disc-like component covering the outside. The cover portion may be arranged movably parallel to an axis of the wheel rim between the open position and the closed position, in the open position opening a ring gap between an edge of the cover portion and the wheel rim.

A retainer for a segmented annular heat shield of a wheel includes a first end, a second end opposite the first end, and a body extending between the first end and the second end. Both the first end and the second end are configured to be coupled to at least one of the wheel and a torque bar. Further, the body includes opposing longitudinal sides configured to respectively engage and secure a respective heat shield segment of the segmented annular heat shield. Also, the retainer includes a cover coupled to and extending over at least the body, with an air gap being defined between the body and the cover.

A brake assembly includes a wheel hub having a radially-outer diameter and a plurality of splines that are spaced apart around the radially-outer diameter. A brake disc is mounted on the wheel hub and has a radially-inner diameter and a plurality of pockets that are spaced apart around the radially-inner diameter. The pockets receive the splines such that the brake disc rotates with the wheel hub. Each pocket has opposing axially-extending side walls. Each side wall has an outwardly-chamfered outboard end and an inboard locking recess. A plurality of spacers are radially disposed between the splines and pockets. Each spacer has opposing arms connected together by a brace. Each arm has an outwardly-chamfered end and outwardly-projecting locking foot which together mate with the outwardly chamfered outboard end and inboard locking recess, respectively, so as to lock the spacer in the pocket.

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 tire support rim for track roller associated with a flange is provided with a circular tire (2), and a support rim (1) for an annular track roller producing a flange. The rim (1) defines a peripheral edge intended to bear a tire, a medial edge in contact with the medial portion of the roller, and two opposite faces producing, on the one hand, an open face and, on the other hand, a bearing face positioned against the surface of the flange of the roller. The rim (1) incorporates a cooling device having at least one circulation duct for air passing through the thickness of the rim from an orifice (51) of the open face such that the duct has a portion at the medial edge and a portion positioned radially on the bearing face between the medial and peripheral edges.

A wheel cover assembly for a vehicle wheel is provided. The wheel cover assembly includes a mounting apparatus and a wheel cover. The mounting apparatus is adapted for mounting on lug nuts of a vehicle wheel. The mounting apparatus is adjustable in both axial and radial directions. Dual quick release connections releasably connect the wheel cover to the mounting apparatus. The wheel cover may include a plurality of ventilation openings, and a plurality of radially extending fan blades may be disposed on an inner surface of the wheel cover.

The disclosure is directed to a wheel having a rim that is at least partially made from several layers of fiber-reinforced plastic, and a wheel center having multiple spokes extending from a wheel hub, which constitutes an axis of rotation, to the rim in a radial direction. According to the disclosure the rim comprises a rim well extending in transversal direction between an inboard flange and an outboard flange suitable to receive a tire to be mounted thereon. The wheel includes a circumferential collar that extends from the outboard flange radially inwards towards the axis of rotation and that has an outboard collar face that constitutes an aerodynamic surface.

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 gap 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 gap, and a fastening bolt that couple to the hub fastener through the spring plate.

In one aspect of the present disclosure, a commercial vehicle brake rotor is provided that includes a unitary, one-piece annular body having a central axis of rotation. The annular body includes vents and a braking portion having inboard and outboard braking surfaces. The annular body includes a central mounting flange having through openings to receive studs of a wheel hub. The through openings each have at least a portion thereof extending axially intermediate the inboard and outboard braking surfaces of the annular body. The annular body further includes inboard and outboard air inlets in communication with the vents.

A detachable airplane wheel prerotation/landing brake cooling device is disclosed that comprises: an outer circular cage rim, an inner circular cage rim confronting and spaced apart from the outer circular cage rim, and a plurality of spaced apart arcuate blades spanning across and connecting the outer circular cage rim to the inner circular cage rim at a slant. Each arcuate blade includes a first section connected to the outer circular cage rim and a second section connected to inner circular cage rim. The plurality of slanted arcuate blades are, when the detachable airplane wheel prerotation/landing brake cooling device is being impinged by an airstream during the landing of the airplane, configured to (i) rotate the wheel about the axle in a forward direction, and (ii) funnel air into the plurality of annular spaces adjacent to the plurality of heat shields to thereby remove heat away from the disc brake assembly.
