A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

A wheel assembly includes a split wheel, a nut, and bolt. The split wheel comprises a first wheel portion and a second wheel portion, and the nut comprises a first portion and a second portion. The first portion of the nut comprises a thrust face engaging the split wheel, the nut defines a bore extending through both the first portion and the second portion, the bore in the first portion is nonthreaded, and the bore in the second portion is threaded. Further, the bolt extends through the first wheel portion and the second wheel portion, with a threaded end of the bolt extending through the first portion of the nut and being coupled to the second portion of the nut, according to various embodiments. The effective bending length of the bolt is greater than the clamped length of the bolt.

A wheel assembly includes a wheel portion comprises a web having an inboard surface. The web may define a torque bar retention slot that extends from the inboard surface of the web. The wheel assembly may also include a bushing disposed in the torque bar retention slot, wherein the bushing comprises an open end and a closed end. Still further, the wheel assembly may include a torque bar coupled to the wheel, and the torque bar may include a boss extending into the bushing through the open end of the bushing such that the boss of the torque bar is at least partially disposed within the torque bar retention slot of the wheel portion.

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 composite wheel assembly and method of construction thereof is provided. The composite wheel assembly includes a lightweight annular aluminum barrel having an inner surface and an outer surface configured to support a tire thereon. A lightweight metal central hub assembly is fixed to the barrel. The metal central hub assembly includes a central hub portion and plurality of support spokes extending outwardly from the central hub portion to free ends, wherein the free ends are fixed to the inner surface of the aluminum barrel. A wheel cladding contrasting in at least one of material type, color, texture and surface finish to an outwardly facing surface the central hub assembly is fixed to the outwardly facing surface of the central hub assembly.

A non-inflatable tire for an agricultural implement, including a sole, a tread, and a pair of sidewalls connecting the sole to the tread is provided. A first sidewall extends from the sole to the tread, while the second includes an internal portion which extends from the sole to the tread and an external portion projecting from the tread. The first sidewall and the tread are designed so as to jointly hold the external portion of the second sidewall in line with the internal portion.

Provided is a wheel (6a) in which a disk (62) includes a first rib (62a) extending in a radial direction, and protruding out on one side in a direction of a central axis a1. A hub (61) of the wheel (6a) includes a first blade portion (61d1) extending in the radial direction. At least one of a pair of side surfaces of the first rib (62a) is inclined relative to a plane including the central axis a1 of the disk (62), and the first blade portion (61d1) is fixed to the inclined side surface on one side of the central axis a1.

A method for providing motor vehicle wheels made of composite material based on carbon fiber includes the steps of, dividing each wheel into a plurality of portions having small dimensions; providing a a first portion with the terminal edges designed to mate with corresponding edges of a respective second portion; mating the portions, arranging them subsequently within a respective mold whose shape and dimensions are conjugate with respect to those of the wheel to be manufactured; and bringing the mold and its contents to a predefined temperature. The method further includes injecting into the mold a resin in the liquid state, the resin being injected at high pressure and high temperature, forming the matrix of the composite that constitutes the wheel; maintaining the pressure and temperature of the mold within predefined ranges for a time interval that is required for the at least partial cross-linking of the resin; and extracting the wheel from the mold.
