AI Technical Summary

Problems solved by technology

The increase in the radial dimension of the protrusions and the thickening of the protrusions mean that the weight of the hub body increases and the aerodynamic resistance increases during movement

Embodiment Construction

[0044] figure 1 shows a hub body 1 according to the invention comprising a central tubular body 2 extending along the main axis of rotation X. At the ends of the tubular body 2 there are provided a first flange 3 and a second flange 4 for connecting spokes. The hub body 1 is preferably made of metal, especially aluminium, but alternatively it can also be made of a different material, like for example carbon fibre. On the first flange 3, four spoke attachment areas 5-8 arranged at an angle of 90° to each other are defined, and on the second flange 4, four spoke attachment areas 9-12 arranged at an angle of 90° to each other are defined. , and the spoke coupling areas 9-12 are angularly offset from the spoke coupling areas 5-8 of the first flange 3 by 45°.

[0045] Each of the spoke attachment areas 5-12 of the first and second flanges 3,4 includes a corresponding set of spoke attachment holes 17-24 formed on the inner surface 13,15 and the outer surface of the respective fla...

Abstract

A hub body of a spoked bicycle wheel comprises spoke attachment holes made in the hub body in a direction substantially parallel to a rotation axis of the hub body. Said holes comprise a first set of holes at a first radial distance from the rotation axis and a second set of holes at a second radial distance from the rotation axis, greater than the first radial distance.

Description

field of invention [0001] The present invention relates to a hub body for a spoked bicycle wheel, in particular to a hub body of the type in which the spoke coupling holes are made parallel to the axis of rotation of the hub body; It also relates to a hub and a wheel comprising such a hub body. Background technique [0002] By the term "hub" we generally refer to the assembly of the hub body within which the axle is rotatably coupled to the bicycle frame via its ends; the hub body is attached to the wheel's on the rim and rotate integrally with the rim. [0003] With regard to the term "direction" of the spoke coupling hole, we mean the main direction in which the said hole extends through the hub body; this direction is the direction in which the perforating tool should ideally be arranged in the case of making the hole by means of the chip removal method ; it is also the direction in which the longitudinal axis of the part of the spoke or of the spoke coupling element (s...
