In some examples, an aircraft wheel assembly includes an axle, a bearing assembly, and a hub defining a bearing bore. The bearing bore may be configured such that the dynamic radial and axial thrust bearing reactions between the axle and the hub results in a first reaction force F.sub.R applied to the hub, the first reaction force F.sub.R having a radial component, and a second reaction force F.sub.N applied to the hub, the second reaction force F.sub.N having both a radial and an axial component.

A stable, low-weight wheel which is particularly suitable for high system-weight bicycles, such as electrically powered bicycles and cargo bikes, includes a hub, at least three solid-body spokes disposed rotationally symmetrical to the wheel axis, and a rim. The body of the hub, spokes and rim is made in one piece by injection molding of a glass-fiber reinforced thermoplastic. The spokes have an S-shaped cross-section with an opening angle which increases in the direction of the rim, taper from the rim towards the hub in a central cross-section of the wheel, and taper from the hub towards the rim in a wheel cross-section running through the center of least one spoke. A method for producing the wheel is also provided.

The present disclosure provides AlSiMg aluminum alloys comprising a deliberate addition of Mn between 0.05-0.40 weight percent to increase at least one tensile property (such as the yield strength) of an aluminum product comprising such alloy. The AlSiMg alloy comprises, in weight percent, 5-9% Si, 0.35-0.75% Mg, 0.05-0.4% Mn, less than 0.15% Fe, up to 0.15% Ti, 0.005-0.03% Sr and the balance being aluminum and unavoidable impurities, wherein the unavoidable impurities may be present in an amount of up to 0.05% each and up to 0.15% total. The present disclosure provides a foundry ingot comprising the above AlSiMg aluminum alloy, a process for making the above AlSiMg aluminum alloy and an aluminum alloy obtainable by said process.

A method for casting an aluminum wheel comprises preparing a melt having a predetermined chemistry and including silicon in a range from 8.5 to 10% mass and aluminum; degassing and refining the melt; adding a grain refiner including aluminum-titanium-vanadium-boron (AlTiVB) and a master alloy to the melt; and casting the aluminum wheel.

A number of variations may include a product including a substrate comprising a metal comprising an etched region and a first layer comprising a clear coat overlying the etched region wherein the etched region is constructed and arranged to improve filiform corrosion resistance on the substrate.

Disclosed is an intelligent hub cleaning device, including a base (1), a mounting transition plate (2), a nozzle adjusting module (3), hub conveying modules (4) and a work fixture (5), in which the nozzle adjusting module (3) is connected onto the mounting transition plate (2), and the mounting transition plate (2) is fixed on the base (1); the work fixture (5) is arranged at a position parallel to the base (1), so that the nozzle adjusting module (3) can face the front side of a hub (6); and the hub conveying modules (4) are arranged on two sides of the work fixture (5). The device is simple in structure, and one device can complete cleaning of multiple types of hubs, thereby greatly reducing the input of enterprises on cleaning devices and saving a lot of money for the enterprises.

The present invention concerns an axle unit comprising a stub axle and an axle tube, wherein the stub axle has a longitudinal channel which extends inside the stub axle substantially along a stub axis, wherein the stub axle has a transverse channel which extends inside the stub axle substantially transversely to the stub axis and opens to the environment at the outer face of the stub axle, wherein the longitudinal channel and the transverse channel are connected together, wherein the stub axle has a stub joining region to which the hollow-bodied axle tube can be secured.

A non-pneumatic wheel having a plurality of lengthwise reinforced spokes each spoke having at least one separation extending from the radially inner end of each of the plurality of spokes to the radially outer end of each of the plurality of spokes forming at least two spoke web sections where the radially inner end of each spoke is mechanically attached to the hub and the radially outer surface of each spoke is bonded to the outer annular band.

A wheel hub for a heavy-duty vehicle includes a first and second tubular hub segment. The first tubular hub segment has a first annular end surface. The second tubular hub segment has a second annular end surface and a radially extending flange. A continuous, circumferential joint is formed at the interface of the first annular end surface and second annular end surface.

The present invention relates to a wheel comprising a hub formed inside the wheel, a rim portion separated outwardly from the hub and forming a circumference on which a tire is fitted, a plurality of spokes connecting the hub and the rim portion, wherein the rim portion is characterized by including an air-tight rim formed in a cylindrical shape, and a protruded grid portion having a plurality of first recesses by being protruded from and equispaced around the circumference of the air-tight rim. In this way, the honeycomb rim-type wheel can be readily manufactured to have lightweight using a single casting job without sacrificing durability thanks to the protruded grid portion on the circumference of the air-tight rim, thereby reducing time and cost for manufacturing by reduced usage of molten metal.
