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.

A flanged wheel hub for wheel hub bearings, the wheel hub having a flange provided with a plurality of threaded through holes and, for each threaded through hole, a respective radial arm, which has a respective axial thickness (SAB) to act as a strengthening element for the flange, at least at the position of the threaded through holes, the wheel hub being produced by forging with the flange and the arms made in one piece, and also having, for each threaded through hole, an annular boss, which is also forged in one piece with the wheel hub and is arranged around, and penetrated by, the corresponding threaded through hole for the purpose of increasing the mechanical strength characteristics of the wheel hub.

A structure of a bicycle wheel rim is disclosed. It comprises an inner rim frame and a composite rim body. The inner rim frame is provided with an inner rim part, two lateral ring parts respectively disposed on both sides of the inner rim part, two hooks respectively disposed on terminals of the two lateral ring parts, and an opening formed between the two hooks and having a supporting part. The composite rim body encapsulates the inner rim part, the two lateral rings and the two hooks.

A low impact turf wheel having a wheel rim including an inner and outer surface, a plurality of pegs extending radially outward from the outer surface of the wheel rim, wherein the plurality of pegs maintain the wheel rim above an area of turf, and a hub. A turf wheel having a wheel rim having an inner and outer surface, a plurality of pegs extending radially outward from the outer surface of the wheel rim, wherein the peg comprises a stem, a collar and a lug, and wherein the lug includes a limited surface area to provide a ground contacting tread, and a hub.

A wheel assembly including a cover portion permanently attached to a wheel. The wheel includes a wheel central hub portion, a wheel outer peripheral rim portion, a plurality of wheel spoke portions extending between the wheel central hub portion and the wheel outer peripheral rim portion, and a plurality of wheel turbine openings disposed between adjacent ones of the plurality of wheel spoke portions. A cover portion is configured to overlie a portion of the wheel portion. The cover portion is configured to overlie one or more of the wheel central hub portion; the plurality of wheel spoke portions, and the plurality of turbine openings or the wheel outer periphery. An adhesive is disposed between an outboard surface of the wheel and the inboard surface of the cover portion to permanently secure the cover portion to the wheel portion. When the cover portion is secured to the wheel, substantial portions of the plurality of wheel spokes, the wheel central hub, or wheel outer periphery remain exposed.

A road wheel for a vehicle includes a face portion and a rim portion. The face portion is formed from a metallic alloy and defines a central portion plurality of spokes extending between the central portion and a proximal bead element. The rim portion is formed from a composite material and defines an annular wall circumscribing a wheel axis extending to a distal bead element from said face portion. The proximal bead element is defined by the metallic alloy and the distal bead element is defined by the composite. The face portion and the rim portion are interconnected in interlocking engagement.

The invention relates to a method for producing a wheel rim having a rim base of a fiber composite material. The problem to be solved by the invention is that of improving the production of the wheel rim, and especially to ensure a reliably functioning wheel structure which can be achieved with little financial and technical outlay. The problem is solved in that during the production of the rim base (2) a connection element (3, 13, 21, 31, 42, 51) is joined to the rim base (2), said connection element (3, 13, 21, 31, 42, 51) being designed and arranged in such a way that a wheel disc (4, 14, 22, 36, 45) can be connected to said connection element (3, 13, 21, 31, 42, 51).

A hub for bicycles includes a hub shell which is rotatably supported relative to a hub axle by two roller bearings disposed on opposite ends of the hub shell, a rotor rotatably supported relative to the hub axle by two rotor bearings, and a freewheel device having an interacting hub-side freewheel component and a rotor-side freewheel component. The two freewheel components each have axial engagement elements and are axially movable relative to one another between a freewheel position and an intermeshing engaging position. The rotor is disposed in the same axial position both in the freewheel position and in the engaging position. A driving torque is transmitted in the engaging position. The hub-side freewheel component has an inner central receiving space with a bearing seat and a roller bearing received to rotatably support the hub shell. The hub-side freewheel component includes an appendix protruding outwardly from the axial body section.

A rim for a bicycle wheel includes a radially outer tire engaging portion having a first tire retaining portion and a second tire retaining portion spaced apart from the first tire retaining portion. The first tire retaining portion includes a first tire retaining section having a first outer wall and a first tire retaining wall opposite and spaced apart from the first outer wall. The second tire retaining portion includes a second tire retaining section having a second outer wall and a second tire retaining wall opposite and spaced apart from the second outer wall. The radially outer tire engaging portion is made of a composite material. The first outer wall and the first tire retaining wall, and the second outer wall and the second tire retaining wall, respectively, are separated by a material having a lower density than the composite material.
