Problems solved by technology

However, this wheel has the disadvantage that the wire spokes contact each other at one or more points due to the crossing of the wire spokes, and this contact causes the wire spokes to bend inwardly after assembly, resulting in abnormal stress concentrations and unacceptable instability of

Embodiment Construction

[0016] In the following several specific embodiments, individual components appearing in a specific embodiment may actually be interchanged with other different components present in other specific embodiments.

[0017] With regard to the figures, the reference numeral 1 generally designates a bicycle wheel according to the invention, in particular for racing and mountaineering bicycles.

[0018] The wheel includes a rim 2 and a central hub 3, both of which are connected to each other through scattered steel wire spokes. The hub 3 has a first flange 4 and a second flange 5, both of which are lateral and roughly dish-shaped. shape and respectively have inner surfaces 4a, 5a and outer surfaces 4b, 5b.

[0019] According to the invention, the wire spokes form a first set of radial elements 6, which connect said first flange 4 to said rim 2, and are equiangularly spaced from each other at a predetermined angle; and a second set of radial elements 6, which are distributed at equia...

Abstract

A bicycle wheel, particularly for racing and mountain bicycle, comprising a hub (3) that has two flanges (4, 5) connected to a rim (2) by way of wire spokes, said wire spokes forming a first plurality of radial elements (6), which are mutually angularly equidistant by a preset angle and connect said rim (2) to the first flange (4) of said hub (3), and a second plurality of radial elements (6), which are mutually angularly equidistant by said angle, are offset by half of said angle with respect to said first plurality and connect said rim (2) to the second flange (5) of said hub (3), each one of said radial elements (6) being constituted by a first wire spoke (7) and a second wire spoke (8) which are substantially parallel.

Description

technical field [0001] The invention relates to a bicycle wheel for racing and mountaineering bicycles. Background technique [0002] Racing bikes and bikes for rough or mountain touring are now equipped with extremely light weight wheels through the use of new materials and modern manufacturing techniques. [0003] At the same time, such wheels must have great mechanical strength and a stiffness suitable for the characteristics of the road surface. Wheels, which are particularly robust when subjected to stresses in use, are produced in one piece by pressure die casting, but are usually too heavy to be used in certain situations or environments. [0004] A compromise between robustness and low weight can be achieved with conventional wheels, where the rim is connected to the hub by scattered wire spokes of different shapes and sizes. However, this wheel has the disadvantage that the wire spokes contact each other at one or more points due to the crossing of the wire spokes...
