A bicycle rim and/or wheel are provided. The bicycle rim and/or wheel includes a single wall formed into the bicycle rim. The wall is formed of composite material having a spoke attachment portion and a tire attachment portion formed therein. The composite material may include at least two different materials, or fibers used as reinforcement material, forming layers of a thickness of the rim.

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 bicycle rim and/or wheel are provided. The bicycle rim and/or wheel includes a single wall formed into the bicycle rim. The wall is formed of composite material having a spoke attachment portion and a tire attachment portion formed therein. The composite material may include at least two different materials, or fibers used as reinforcement material, forming layers of a thickness of the rim.

A hybrid wheel including a functional rim, a center disc, and a wheel face insert, wherein the wheel rim and the center disc are made of a specified material, and wherein the wheel face insert is made of a dissimilar material. The wheel face insert can be secured to the center disc by at least one of screws, pins, rivets, or structural adhesive, and/or the wheel face insert can be secured to the functional rim by at least one of screws, pins, rivets, or structural adhesive.

The invention relates to a wheel rim having a rim base (3) of fiber composite material and a wheel disk (2) connected to the rim base (3) in a radial marginal section. The radial marginal section of the wheel disk (2) comprises at least two partial layers (4, 5) on each of which a contoured joining zone (6, 7) which extends substantially axially is formed, the joining zone being flat connected to the rim base (3).

The invention relates to a wheel, comprising a metal disk and a rim which rim comprises a metal part and a continuous fiber reinforced composite part present on an outer surface of the metal part of the rim, wherein the continuous fiber reinforced composite part comprises a semi-crystalline polyamide with a melting temperature of at least 180 C. The invention also relates to a process for preparing a wheel as well as a tape for use in production of the wheel.

An article made by composite material includes a body made of reinforced fiber. The body has at least two opposing sidewalls. A foam component is embeddedly disposed in each sidewall. Owing to the two foam components, the finished composite structure is lightweight and has high mechanical strength.

An adapter for a rolling assembly comprising a tire having two beads (B), a rim (J) with two rim seats (7), said adapter connecting one of the beads and the rim. The adapter has an axially inner end (10) comprising inner reinforcer element (16), and an axially outer end (15) comprising outer reinforcer element (15), respectively mounted on a rim seat (7). Body (11) connects said outer end (9) to said inner end (10). Main reinforcement connects said outer reinforcer (15), and said inner reinforcer (16), a substantially cylindrical adapter seat (18) receiving one of said beads (B), an adapter bearing face (21) substantially contained in a plane perpendicular to the rion otataxis. The reinforcer element (15) of the axially outer end (9) is entirely situated axially outside the bearing face (21), and in that the body (11) comprises, opposite the adapter seat (7), an annular seat reinforcer (19).

Vehicle rim for mounting of a tire, comprising: an axially central part (20) comprising a disc; two lateral parts (31, 32), at least one of the lateral parts being separate from the axially central part, each of the lateral parts having a rim seat to receive a bead of a tire, the axially central part and the two lateral parts being made from a rigid matrix; an intermediate part (41, 42) that forms the only mechanical link between the axially central part and each lateral part that is separate from the axially central part, this intermediate part being made of a flexible matrix, the Young's modulus of uniaxial extension of the flexible matrix being greater than and equal to 50 MPa and less than or equal to 400 MPa; wherein the Young's modulus of uniaxial extension of the rigid matrix is greater than or equal to 5 GPa.

Adapter providing the connection between one tire bead and the rim. An axially inner end of the adapter is mounted on the rim seat, an axially outer end is mounted on the rim seat, a body connects said outer end to said inner end, a substantially cylindrical adapter seat receives one of said beads, and an adapter bearing face is substantially contained in a plane perpendicular to the axis. The reinforcer element of the axially outer end is entirely situated axially outside the bearing face. The body comprises, opposite the adapter seat, an annular seat protuberance, said protuberance comprising at least one rubber composition.
