Embodiment Construction

[0042] figure 1 A bicycle wheel 1 according to a preferred embodiment of the present invention is shown. Traditionally, the wheel 1 includes: a profiled rim 2, which is designed to support an inner tube or tire (not shown) on the periphery; a hub 3, which is located in the center of the rim 2 and is designed to enable the wheel 1 to be connected to the bicycle frame And rotate on the bicycle frame; and spokes 4, which connect the inner part of the rim 2 to the hub 3.

[0043] Such as figure 2 with Figure 5 As shown, the rim 2 is preferably (in a manner known per se) made of a composite material 2 made of carbon fiber bundles (strands) impregnated with epoxy resin. 2 Surface covered structure foam core 2 1 constitute.

[0044] Such as figure 2 As shown, the hub 3 includes a central shaft 31 traditionally made of aluminum. Two ball bearings 32, 33 and assembly nuts 34 are mounted on both ends of the central shaft. The ball bearings 32, 33 are blocked by the two end flanges 5. , 6...

Abstract

The present invention relates to a wheel (1) particularly for a cycle, including a circular rim (2), a hub (3) concentric with the rim, and spokes (4) connecting said hub (3) to said rim (2), the rim, the hub and the spokes being made of a polymerized composite material, characterized in that the spokes (4) are paired two by two on either side of the bond plane of the wheel and are attached without tension at their ends onto the hub (3) and onto the rim (2).

Description

Technical field [0001] The invention relates to the field of design and manufacture of equipment made of high-performance composite materials for sports, especially bicycle sports. [0002] The invention particularly relates to a new type of bicycle wheel. The rim, spokes and hub body of the bicycle wheel are all made of composite materials, especially carbon fiber-based materials. Background technique [0003] In the field of cycling, the performance improvement of contestants, professional athletes or amateurs is mainly related to the technical improvement of the materials used. This technical improvement of materials mainly depends on the quality of each component of the bicycle, their stiffness and the results obtained in terms of aerodynamic quality. [0004] Regarding bicycle wheels, the main performance indicators are high rigidity, small mass and low moment of inertia. [0005] Over the years, through the use of carbon fiber-based composite materials, especially for the manuf...
