A hub and spoke assembly includes a hub body having a first end and a second end. Projections are on each end. The projections are spaced apart from each adjacent projection about a rotational axis of the hub. Each projection comprises a base portion joined to the hub body and a support extending from the base portion to a free end. A plurality of spokes is provided. Each spoke comprises an elongated braided fiber having a loop at a first end and a second end configured for attachment to a rim. At least one spoke is joined to each support of each projection.

An omnidirectional wheel includes a plurality of first and second rollers, a plurality of roller support parts, a wheel hub, and a fixing member. The wheel hub has a shaft portion and an extension. The fixing member and an elastic body are disposed to surround the shaft portion. Spaces are provided between the elastic body and the shaft portion, or between the elastic body and the roller support parts. A plurality of first pins and second pins are formed to protrude from the extension and the fixing member, respectively. The elastic body has a plurality of first holes and second holes. The first holes and the second holes are shifted from each other in a circumferential direction of the elastic body.

A bicycle rim is made with a plurality of layered, each of which is formed of structural fibres incorporated in a polymeric material. The rim has a radially outer peripheral channel with an upper bridge extending between the wings for holding a tyre. The peripheral channel comprises an inner layered structure, extending between wings and at least one wrapping layered structure, wound on the inner layered structure at least at the end of the wings, the inner layered structure and the wrapping layered structure being included in the plurality of layered structures.

A bicycle wheel rim, comprising a wall made of composite material having a plurality of perforated spoke-attachment seats, wherein each perforated seat is delimited by at least one first area comprising an amassment of continuous structural fibers and at least one second area circumferentially spaced apart from said first area and comprising cut structural fibers. A process for manufacturing the aforementioned rim is also disclosed.

An insert for the rim of a spoked bicycle wheel that has a spoke hole. The insert has a portion configured to abut against a spoke attachment element with an enlarged head and a holding element that prevents movement of the spoke attachment along said longitudinal axis of the spoke hole.

A wheel assembly includes a mounting plate for attachment to a rotatable axle; a plurality of friction plates each engaging one of a plurality of parts of a tire assembly; and a plurality of cable members each connecting the mounting plate to the tire assembly such that each cable member extends radially outward through a first hole in one of the friction plates and radially inward through a second hole in the one friction plate to form a loop about the one friction plate and the one part of the plurality of parts of the tire assembly.

A bicycle rim assembly includes a rim defining a central plane and comprising annular inner and outer walls. The outer wall includes first and second bead seats separated by a center well. First and second annular projections are spaced laterally from each other relative to the central plane and extend substantially radially outwardly from the outer wall. Each of the annular projections includes a radially outer face and a laterally inner face. Right and left covers are spaced from each other and are preferably coupled to the rim to cover at least a portion of the laterally inner face and the radially outer face of the first and second annular projections, respectively, and also the first and second bead seats, respectively. One or both of the right and left covers can be fiber reinforced. First and second pieces of tape can be overlapped and used to secure the covers to the rim.

The present disclosure relates to an axle beam, in particular an axle bridge, for a motor vehicle, preferably a commercial vehicle. The axle beam has a first axle beam shell and a second axle beam shell which is connected, in particular welded, to the first axle beam shell in order to configure a tubular body. The tubular body has an inner circumferential face with a plurality of flat sections which form a non-round cross section of the tubular body. The axle beam has a reinforcing component which has a non-round cross section, is arranged within the tubular body, and bears at least partially against the flat sections of the inner circumferential face of the tubular body.

A bicycle hub unit configured to be stably coupled to a frame of a bicycle includes a hub axle and a rotation restriction member. The hub axle is configured to be coupled to the frame of the bicycle. The rotation restriction member is configured to couple the hub axle to the frame so that rotation relative to the hub axle and the frame is restricted. At least one of the hub axle and the rotation restriction member has a cable guide structure configured to guide a cable, which electrically connects an electric component and an electronic component, in a region including the rotation restriction member in an axial direction parallel to a center longitudinal axis of the hub axle.

A wheel cover assembly for a vehicle wheel may include a cover body having a cover body outer surface, a cover body inner surface, and a cover body outer edge having an outer diameter that is greater than an inner diameter of a stiffener rib extending inward from an inner surface of the wheel rim and less than an inner diameter of an open end flange of the wheel rim. The wheel cover assembly may further include a cover mounting mechanism operatively connected to the cover body and having a locking position wherein the cover mounting mechanism engages the stiffener rib when the cover body inner surface is facing and engaging the stiffener rib and a cover locking position wherein the cover mounting mechanism engages the stiffener rib to secure the wheel cover assembly to the vehicle wheel.
