A spoked bicycle wheel having a rim at least partially comprised of a composite material. The rim has at least one spoke attachment chamber with a plurality of spoke attachment holes. The wheel has a plurality of spokes coupled with the rim and a spoke attachment element partially inserted in a respective spoke attachment hole. The wheel includes a holding element that prevents the movement of said spoke attachment element along a radially outer direction. The spoke attachment element has a holding surface configured for abutment against the holding element.

In a pressing step, a first forged product is pressed by a first die, and thereby, a second forged product including a rough flange having a thickness-changing portion is produced. The thickness-changing portion includes a front part protruding frontward from a side of a rough web part and a rear part protruding rearward from the side of the rough web part. Each of the front part and the rear part includes a first part, and a second part that is thicker than the first part and is located farther from the rough web part than the first part. In the pressing step, at least a part of the rough flange that is above or below the web part (thick part) is pressed by the first die, whereby the material of the first forged product in the part is caused to flow frontward and rearward, and the thickness-changing portion is formed.

A disk wheel for a motor vehicle, in particular a single-track motor vehicle, includes: a wheel hub for mounting the disk wheel on the motor vehicle, which wheel hub is concentric to an axis of rotation of the disk wheel; a wheel rim, which is likewise concentric thereto; and a first and a second wheel disk. The first wheel disk and the second wheel disk each extend from the wheel rim toward the wheel hub, are mutually spaced on the wheel hub in a transverse direction which is parallel to the axis of rotation of the disk wheel, and run toward each other as they approach the wheel hub. The disk wheel also has at least two reinforcement ribs, which extend from the first wheel disk to the second wheel disk and interconnect the first wheel disk and the second wheel disk. The reinforcement ribs are distributed evenly around the axis of rotation of the disk wheel.

The present invention explains a process for manufacturing tubeless vehicle wheel without welding using a hoop 100 having an outboard end 101, a centre region 102, an inboard end 103. The process includes spinning the outboard end 101 to obtain a disc region 202, spinning disc end 203 to obtain preform nave region 301. Forming the disc region 202 to obtain a disc profile 401 and a nave region 403, forming the centre region 102, inboard end 103 to obtain a straight rim profile 402. Spinning and forming outer end 405 of the straight rim profile 402 to obtain an outboard flange 502a and spinning the straight rim profile 402 to obtain a concave rim profile 601a with a preform inboard flange 602a. Spinning the concave rim profile 601a to obtain bead seats 701a, well region 703a and, forming the preform inboard flange 602a to obtain an inboard flange 704a.

The production method disclosed is a method for producing a front axle beam. The production method includes a die forging step and a bending step. The die forging step is a step of forging a steel material with dies to produce a forged product including a rough web part, which is to be formed into a web part, and four plate-shaped rough flange parts protruding frontward and rearward from an upper side and a lower side of the rough web part, respectively. The bending step is a step of pressing at least one specified rough flange part, which is at least one of the four rough flange parts, with a first die to form a bent portion in the specified rough flange part such that the bent portion is bent inward in an up-down direction of the forged product.

A method of manufacturing a rim includes placing at least one braided sleeve on a core dimensioned to define a shape of an internal wall of the rim. The method includes inserting the braided sleeves placed on the core, inside a mold that is dimensioned to define a shape of an external wall shape of the rim. The method further includes injecting a resin inside the mold to contact the mold and impregnate the sleeves and other layers with resin. The method also includes curing the resin to form the internal and external walls of the rim and obtain a cured rim having the core connected thereto. The method further includes removing the cured rim and core from the mold and melting the core to get it out of the rim.

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 wheel for a vehicle comprises a rim to support a tire and a wheel disc connected to the rim and configured to engage an axle hub of a vehicle. The wheel disc comprises one or more spokes extending outwardly from a center section of the wheel disc to the rim, each spoke being formed by a substantially planar curbside spoke member and a substantially planar inside spoke member, The curbside and inside spoke members are oriented transversely to each other and to a portion of the center section lying between the curbside and inside spoke members to define a triangle. A plane of the triangle is substantially parallel to a center axis of symmetry of the disc.

A composite bicycle rim, and a process for manufacturing the rim, having a plurality of perforated spoke-attachment seats having spaced apart first and second areas of cut structural fibers. The second area has both end portions of cut structural fibers having a longitudinal dimension greater than the first area's cut structural fibers and continuous structural fibers. At least some of the end portions of the second area's cut structural fibers are mutually juxtaposed or interposed with respect to the second area's continuous structural fibers.

A mower front caster wheel system that includes a caster wheel assembly that rotates about a caster axis, and a stabilizer to be disposed in a bearing housing coupled to a frame of a mower such that a first portion of the stabilizer is in contact with a component that rotates with the caster wheel assembly and a second portion of the stabilizer is in contact with an internal surface of the bearing housing, to provide resistance to rotation of the caster wheel assembly relative to the bearing housing.
