A wheel assembly includes a wheel axle, an inner wheel, and an outer wheel. The inner wheel is mounted on the wheel axle. The inner wheel is rotatable about the wheel axle. The inner wheel is rotatably retained in the outer wheel. The inner and outer wheels include a gap therebetween, and the outer wheel is rotatable eccentrically about the wheel axle.

Disclosed are wheel assemblies for motor vehicle powertrains, methods for making and methods for using wheel assemblies, and motor vehicles with wheel units each composed of a tire and a wheel assembly. For example, a multi-hub wheel assembly for a motor vehicle is disclosed. The motor vehicle includes a tire and a suspension component, such as a hub-and-bearing assembly, mounted to the vehicle body. The wheel assembly includes an outer wheel with an annular rim well attached to a central hub. The central hub mounts onto the vehicle's suspension component, e.g., via lugs and bolts, while the tire mounts onto the rim well. The wheel assembly also includes an intermediate hub with a deflection annular rim attached to a mounting base. The mounting base is attached to the outer wheel. The intermediate hub mounts inside a hollow core of the outer wheel, interposed between the central hub and the suspension component.

Embodiments of the present invention provide methods, computer program products, and systems for selecting subsets of participants in electronic message threads. Embodiments of the present invention can be used to exclude participants based, at least in part, on activity level from message conversations, thereby streamlining message conversation and reducing unwanted message communications.

An alloy for cladding cast iron is disclosed. The alloy may include on a weight basis, about 6.2% to about 9.3% of chromium (Cr), about 3.0% to about 4.5% of iron (Fe), about 1.4% to about 2.15% of silicon (Si), about 0.5% to about 0.8% of boron (B), about 0.1% of carbon (C), and a balance of nickel (Ni) and incidental impurities.

A commercial vehicle wheel cover is provided. The assembly includes two handles and two interlocking cam latch mechanisms. The wheel cover assembly is attached to the wheel hub via two cam latch mechanisms which lock into a collar assembly. The collar assembly includes of two collar halves and a latch that, when installed, applies a compressive force on the axle hub flange holding the assembly to the hub.

Systems and methods are disclosed for aircraft wheels and brakes systems for use in, for example, an aircraft. In this regard, a damper for an axle may comprise a cylindrical canister defining a cavity configured to be inserted into a bore of the axle, the cavity at least partially filled with a damping material. The damper may act as a particle damper or a tuned mass damper to mitigate harmonic vibration of the axle and therefore the wheel and brake system.

A composite wheel assembly and method of construction thereof is provided. The composite wheel assembly includes a wheel having an inwardly facing surface, an outwardly facing surface, a generally cylindrical barrel portion, and a plurality of apertures formed about a central hub aperture. At least one wheel cladding is fixedly bonded to at least one of the inwardly facing surface, the outwardly facing surface, and the generally cylindrical barrel portion. The wheel cladding increases the stiffness and/or strength of the wheel between about 2-16% or greater as compared to the wheel not having the at least one cladding.

A solid wheel for a rail vehicle includes a wheel rim arranged on the circumference of the solid wheel, a tread and a hub for a wheelset shaft, wherein the wheel rim is connected to the hub via an end wall and a rear wall, where the hub is arranged at the center of the solid wheel and includes a longitudinal axis such that a high radial and axial strength of the wheel flange as the basis for a low sound emission is provided by virtue of the solid wheel forming a cavity that is delimited by the end wall and the rear wall, where the end wall and the rear wall transition into each other below the wheel flange in an arched manner, and the end wall has first openings and the rear wall has second openings in order to open the cavity outwards in a spoked manner.

The present invention provides a bicycle rim assembly adapted to be coupled to a hub to create a bicycle wheel. The rim assembly includes a rim and a cover coupled to the rim. The rim defines a central plane and comprises an annular inner wall and an annular outer wall cooperating with the inner wall to define a cavity. The rim further includes annular projections spaced laterally relative to the central plane and extending substantially radially outwardly from the outer annular wall. The cover includes sidewalls disposed on lateral sides of the rim adjacent the projections, each sidewall including a lateral inner portion having a lateral thickness. The cover further includes an annular ring portion interconnecting the sidewalls, the annular ring portion including a radial thickness less than the lateral thickness of the lateral inner portion of the sidewalls. Preferably, the rim comprises a metallic material and the cover comprises a non-metallic material. For example, the rim can comprise aluminum or an epoxy matrix composite, and the cover can comprises a polymeric material, such as ultra-high molecular weight polyethylene. In addition, a radial thickness of the entire cover is preferably substantially less than a radial thickness of the entire rim.

In one embodiment, the projections include a laterally inwardly facing surface, a laterally outwardly facing surface, and a radially outwardly facing surface. In this embodiment, the cover engages at least a portion of each of the laterally inwardly facing surface, the laterally outwardly facing surface, and the radially outwardly facing surface. Preferably, each annular projection has a smoothly radiused radially outwardly facing surface, and each laterally outwardly facing surface that lies in a radial plane substantially parallel to the central plane.

An axle assembly having a wheel flange with a central opening and a slot having an end dimensioned to fit within the wheel flange central opening. A molten binder, such as molten zinc, fills the space in between the wheel central opening and the shaft end. Upon cooling, the binder locks the wheel flange and shaft together.
