The invention relates to a device (3) for protecting a wheel rim (2) of a motor vehicle, wherein: an outer side of a rim flange (4) is covered by the device (3); the device (3) consists of a ring (5), the diameter of which is matched to that of the rim flange (4); and the ring (5) has a circumferential tongue (5.2) for fastening the device (3) to the rim flange (4), which tongue can be clamped between an inner side of the rim flange (4) and a side wall of a tyre (1). The device (3) is intended to be held securely on the wheel rim (1) even at very high speeds and correspondingly large forces acting on the device (3). No changes to the wheel rim (1) are necessary, and installation is simple. This is achieved in that the single ring (5) is produced from a hard material and has a continuous radial gap (6) and in that end faces (5.3) of the ring formed by the gap (6) can be connected by means of a clamping screw (8).

A shaped preform component (200) for a face portion (104) of a composite wheel (100), the shaped preform (200) having a hub (206) that extends around a central axis (Y), the shaped preform component (200) being formed from a cured composite fibre material having a compressibility of <2% volumetric under moulding conditions of 50 bar hydrostatic pressure and a temperature of 60 to 200° C.

A chin ring heat shield for a wheel assembly arranged to provide a shield between convection and radiation heat from braking components and a tire of the wheel assembly, the chin ring comprising a first, radially extending, flat portion extending from a first chin ring end and a second, concave portion extending generally axially away from the first portion to a second chin ring end, wherein the axial length from the first chin ring end to the second chin ring end is sufficient to block a line of sight between the braking components and the tire when the chin ring is mounted between the braking components and the tire.

A tool device and its use for manufacturing a bicycle rim, having opposite rim flanks, a rim well and a rim base and rim flanges configured on the radially outwardly ends of the rim flanks, wherein the tool device includes two molding devices and a circular device. The circular device forms the rim well and the axially inwardly oriented surfaces of the rim flanges. The circular device includes an annular unit of a less elastic material and at least one cover of a more elastic material. Alternately, the molding devices each include a molding unit of a less elastic material and at least one cover of a more elastic material, for attachment thereto. The thickness of the cover is between one eighth of the minimum wall thickness of the rim well of the rim manufactured and eight times the minimum wall thickness of the rim well of the rim manufactured.

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.

Systems and methods for a heat-insulated wheel are disclosed herein. A wheel may comprise a wheel body comprising an outer diameter surface, an inner rim on an inboard side of the wheel body, an outer rim on an outboard side of the wheel body opposite the inner rim, and a heat insulator coupled to the outer diameter surface between the inner rim and the outer rim.

A wheel having a longitudinal plane normal to an axis of rotation. The wheel has a rim with side surfaces on opposite sides of the longitudinal plane. A hub is concentrically disposed relative to the rim. Two unitary side elements are disposed on opposite sides of the longitudinal plane and are coupled to the rim and to end portions of the hub. Each of the unitary side elements has an annular sidewall, a flange portion, and a plurality of spokes that do not cross the longitudinal plane and that integrally interconnect the annular sidewall and the flange portion. An end portion of each spoke of the one side element is tied to the end portion of an aligned spoke of the other side element adjacent to the sidewall to restrict the tied end portions from moving away from each other.

A composite material body (10) includes a first material layer (20) and a second material layer (30) overlapping the first material layer (20). The first material layer (20) and the second material layer (30) are wound to form a flexible and circular rod. Impact absorption is effectively improved and impact resisting strength is enhanced because energy-absorber or damping material or its composition is attached into the composite material body (10). Technical characteristics, effects and objects of this invention are achieved thereby.

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.

Adapter for a rolling assembly, of axis of rotation X-X′, comprising a tire (2), a rim (3), and an adapter (100), said adapter comprising an axially inner end (10), an axially outer end (11) and a body (12), wherein said axially outer end comprises an outer reinforcing element (15) which is a structure substantially of revolution about the axis X-X′ comprising a plurality of windings of at least one wire that are arranged axially beside one another over several layers radially superposed on one another. The section of the outer reinforcement (15) has a ratio of moments of inertia Ix/Iy of greater than 1.3 for an axial width of between 6 and 9 mm, where Ix is the moment of inertia around a first axis passing through its centre of gravity and parallel to the axis of rotation X-X′, and Iy is the moment of inertia around a second axis passing through its centre of gravity and perpendicular to the first axis.
