摘要:
The invention is directed to wheel (1) comprising a rim (2) and a wheel center (3). The wheel center (3) comprises an insert (10) which at least comprises a front pad (11) and a rear pad (12) which are a distance apart with respect to each other and which are at least partially embedded in a composite material (6).

The invention relates to a vehicle wheel (1) comprising a rim (2) for receiving a tyre, and a wheel disc (3) which is connected to the rim (2) in an integrally bonded, force-fitting and/or form-fitting manner, with a connecting region (11) for the releasable connection to a wheel carrier, wherein the wheel disc (3) is formed from a steel workpiece which is heat-treated at least in regions. The problem of providing a commercial vehicle wheel which has high operating strength and safety in comparison to the known prior art is solved in that the wheel disc (3) has a heat-treated microstructure with a tensile strength of between 500 and 1300 MPa and/or a hardness of between 150 and 400 HV 0.1 at least in the transition region (8) for connection to the rim (2).

A FRP rim for a bicycle, including a radially outer tire-engaging portion and a radially inner spoke-engaging portion. A first sidewall is in a spaced configuration with a second sidewall. The first and second sidewalls extend between the radially outer tire-engaging portion and the radially inner spoke-engaging portion and one or more integral bumper is located on an outermost radial extent or peak portion of the radially outer tire-engaging portion.
摘要:
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.
摘要:
A decorative overlay comprised of thin plastic or metal may be securely fastened to a wheel using one or more preformed, solid, dimensionally stable, heat-activatable adhesive bodies. The use of such adhesive bodies offers significant processing and performance advantages over conventional methods for cladding wheels.

Rayon (2) comprenant une âme métallique (5) recouverte au moins dans sa partie centrale d'un fourreau (12) en matériau composite constitué d'un assemblage de fibres noyées dans une matrice, l'âme (5) comprenant une portion d'extrémité prévue pour être attachée à la jante ou au moyeu d'une roue et un corps principal (6) dont la superficie de la section est comprise entre 30% et 50% , de préférence entre 35% et 45% de la superficie de la section de ladite portion d'extrémité. De plus, au niveau du corps principal, le fourreau (12) a une section comprise entre 150% et 500%, de préférence entre 150% et 350%, de la section de l'âme métallique (5) au même niveau. L'âme métallique comprend deux zones d'ancrage mécanique, placée à proximité de ses extrémités, de part et d'autre du corps principal.
