The present invention relates to a multi-part rail wheel with a wheel tyre, a wheel body, an elastic body arranged between the wheel tyre and the wheel body and via which the wheel tyre is supported on the wheel body, and at least one clamping element attached to the wheel body from one end face, via which the elastic body is braced against the wheel body and the wheel tyre by clamping means acting on the wheel body, the wheel body consisting of a light metal material in the region where the clamping means act. The rail wheel guarantees secure bracing of the components with simple assembly and disassembly. This is achieved by at least one counter-bearing element being provided on the end face of the wheel body opposite the clamping element. The counter-bearing element consists of a material which has a higher strength than the wheel body material.

The railway wheel according to the present embodiment has a chemical composition consisting of: in mass %, C: 0.80 to 1.15%, Si: 0.45% or less, Mn: 0.10 to 0.85%, P: 0.050% or less, S: 0.030% or less, Al: 0.200 to 1.500%, N: 0.0200% or less, Nb: 0.005 to 0.050%, Cr: 0 to 0.25%, and V: 0 to 0.12%, with the balance being Fe and impurities, wherein at least in the microstructure of the rim part and the web part, the amount of pro-eutectoid cementite defined by Formula (1) is 2.00 pieces/100 μm or less:

Amount of pro-eutectoid cementite (pieces/100 μm)=a total sum of the number of pieces of pro-eutectoid cementite which intersect with two diagonal lines in a square visual field of 200 μm×200 μm/(5.66×100 μm)×100  (1)

A wheel disc adapted for use in a fabricated vehicle wheel comprising a steel wheel disc defining an axis and including a center mounting portion, an outer rim connecting flange, a plurality of radially outwardly extending spokes connecting the center mounting portion to the outer rim connecting flange and a ventilation opening provided between each pair of adjacent spokes. A width defined by a center wall of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the center wall of the spoke extends generally from the center mounting portion to the outer rim connecting flange or wherein a width defined by outer walls of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the outer walls of the spoke extends generally from the center mounting portion to the outer rim connecting flange.

Hub bearing assembly for a vehicle wheel, the assembly having an axial tubular appendage capable of being inserted into a central hole of a wheel of the vehicle, and wherein the tubular appendage has a radially outer surface of substantially cylindrical shape; a collar of cylindrical shape being mounted on the tubular appendage so as to cover a second centring section of the radially outer cylindrical surface, and having an insert of metallic material and an inner coating layer which at least partially covers the insert and is formed on the insert by galvanizing.

Presented are hybrid metal and fiber-reinforced polymer (FRP) composite wheels for vehicle wheel assemblies, methods for making/using such wheels, and motor vehicles equipped with such wheels. A wheel for a motor vehicle wheel assembly includes a wheel face with multiple spokes that are circumferentially spaced about and project radially outward from a central hub. The central hub rotatably attaches to the vehicle's body, e.g., via a corner module. The wheel face is fabricated, e.g., as a one-piece structure, from an FRP material. A wheel barrel, which circumscribes the wheel face, includes an annular rim that mounts thereon an inflatable tire. The wheel barrel is fabricated, e.g., as a one-piece structure, from a metallic material. Multiple overmold through holes and/or inset tabs are circumferentially spaced about the annular rim. The FRP material extends through and/or surrounds the overmold through holes/inset tabs and thereby mounts the wheel face to the wheel barrel.

A rim assembly for a non-pneumatic tire has at least two rim components including: a first rim component having a first rim flange and a first lip, and a second rim component having a second rim flange and a second lip. The rim assembly further includes a plurality of lateral rim component support structures configured to extend through a plurality of openings of a tire support structure. The rim assembly also includes a first plurality of fasteners securing the plurality of lateral rim component support structures to the first rim flange, and a second plurality of fasteners securing the plurality of lateral rim component support structures to the second rim flange.

A wheel disc includes a hub located centrally within the wheel disc and defining a wheel axis. The wheel disc further includes an outer circumferential edge and a transition portion radially extending between the hub and the outer circumferential edge. The transition portion has a front surface and a rear surface such that the front surface has a relatively smooth profile and the rear surface has a plurality of concentric ring-shaped curvatures formed therein, thereby providing the transition portion with a variable thickness between the front and rear surfaces.

A full face fabricated vehicle wheel having a wheel attached to a wheel disc. The wheel disc includes a hub located centrally within the wheel disc and defining a wheel axis. The wheel disc further includes an outer circumferential edge having an outboard bead seat retaining flange, and an annular transition portion radially extending between the hub and the outer circumferential edge. The transition portion includes a plurality of vent hole regions circumferentially spaced around the transition portion about the wheel axis. At least one vent hole region includes a vent hole formed through the transition portion and defining an outer perimeter such that at least two bridging portions extend inwardly from the perimeter which subdivides the vent hole into at least three smaller holes formed through the transition portion at the at least one vent hole region.

A spoke tension adjustment tool has a longitudinally elongated body with a central longitudinal cavity configured to house an end portion of a spoke. The housing has a longitudinal slit that allows the end portion of the spoke to enter the longitudinal cavity. The longitudinally elongated body has a grip portion and a shaped end portion configured to couple with a stem of a spoke attachment element. The shaped end portion is smaller than the grip portion and smaller than the diameter of a rim spoke attachment hole in which the stem is inserted.

A heat shield for an aircraft wheel assembly is made of a heat shield material evenly distributed across the heat shield along both the circumferential and the axial directions. The heat shield material has a high thermal conductivity greater than 30 W/mK. In various embodiments, the thermal conductivity is greater than 85 W/mK. In this manner, thermal flux is maximized throughout the heat shield to distribute heat evenly across the heat shield in both circumferential and axial directions.
