A reinforced prepreg which is applied to a wear-resistant layer structure of a braking track is provided. The reinforced prepreg includes a fiber fabric and a mixture mixed with the fiber fabric. The mixture includes a resin and a plurality of needle-shaped crystals having microscale or nanoscale sizes mixed with the resin.

A thermoplastic wheel hub (10) includes a center hub (26) for attachment to a wheel bearing (20) of a vehicle. The center hub (26) has a central shaft aperture (28) extending axially therethough and a plurality of lug apertures (30) spaced radially from and circumferentially about the central shaft aperture (28). The thermoplastic wheel hub (10) also includes a plurality of ribs (40) extending radially outwardly from the center hub (26). The thermoplastic wheel hub (10) further includes a cylindrical tire mount (46) connected to the ribs and extending axially in substantially a plane for mounting a non-pneumatic tire (12) thereon.

A spoke for a wheel attaching an outer tread to a hub, the spoke having a first and second spoke elements joined by a joint body comprised of an elastomer connecting the first spoke element to a second spoke element.

A spoke star is made of a fiber-reinforced plastic and formed as a star-shaped closed ring, the spoke star having spokes between a hub-side inner circumference of the spoke star and a rim-side outer circumference of the spoke star, a single fiber bundle running repeatedly in the spoke star between the inner circumference and the outer circumference along spokes of the spoke star. The spokes may be formed as double spokes, the spokes having a loop at the rim-side outer circumference of the spoke star. The loops allow for a better load transfer to the spoke star.

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.

A wheel for a vehicle, in particular a motorcycle or a motor scooter includes a hub region which has at least some portions made of a fiber-reinforced plastic material. The hub region includes a recess in which an insert for connecting the wheel to a vehicle axle is placed. An isolation element which galvanically isolates the insert from the hub region is arranged between the hub region and the insert.

A wheel (1) includes a rim (2) and a wheel center (3) made from a fiber reinforced composite material. The wheel center (3) includes a tubular middle section (6) having a center opening (7) extending in the direction of a wheel axis (19) and having a first and a second end (8, 9). A hub (5) includes a first flange ring (10) and a second flange ring (11). At least one of the flange rings (10, 11) and the tubular middle section (6) are interconnected to each other by a form fit interconnection (12, 13).

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).

The present disclosure relates to a caster, having a housing, having an axle pin which is arranged in a housing opening which is oriented substantially horizontally, and on which at least one wheel is mounted, having, at the top, a pin opening oriented substantially vertically, for receiving a pivot pin, and having a braking device which brakes the at least one wheel, wherein the housing opening for the axle pin allows limited vertical displaceability of the axle pin and the braking device comprises at least one resilient housing part which acts on the axle pin. In order to provide a mechanically reliable braking device, the braking device is additionally provided with at least one spring element which cooperates with the at least one resilient housing part and amplifies the effect of its braking force and/or increases the mechanical load-bearing capacity of the at least one resilient housing part.

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.
