Problems solved by technology

However, such an open seat cannot sufficiently hold the spokes in a direction perpendicular to the longitudinal direction of the seat, and for this reason, the wheel cannot obtain proper rigidity

Embodiment Construction

[0060] Figure 1 shows a wheel 1 comprising a hub 5, a rim 10 and a plurality of spokes 15, the hub 5 is used to be rotatably coupled with a bicycle frame, a tire is mounted on the rim 10, and the spokes 15 are between the hub 5 and the rim 10 stretched and stretched. More specifically, the spokes 15 include a first group of spokes 15 extending near the first axial end 7 of the hub 5 and two groups of spokes 15 extending near the second axial end 8 of the hub 5 .

[0061] In the wheel 1 shown, the projection of the orientation of the spokes 15 on a plane M transverse to the axis of rotation X is inclined by an angle γ, γ′ relative to the radial direction R in a direction T tangential to the hub 5 . In the art, the term "spokes with tangentially connected spokes" is used, and for the sake of brevity, this term will also be used in the rest of the description, but this term should by no means be considered as being limited The spokes 15 extending from the hub 5 in a direction st...

Abstract

The invention concerns a hub (5) for a spoked bicycle wheel, comprising at least one seat (24, 25) for inserting and housing an end portion of a spoke, said at least one seat (24, 25) comprising a notch (30, 31) shaped for the insertion of a spoke in a different direction from a longitudinal direction of the seat (24, 25), and surfaces (40, 41) for stopping the spoke (15) both in both ways of a direction (X, S1) of a rotation axis of the hub (5), and in both ways of a second direction (S2) perpendicular both to the axial direction (X, S1) and to the longitudinal direction of the seat (24, 25). The hub (5), thanks to the configuration of the notch (30, 31), allows the spoke (15) to be easily connected thereto without having to unthread it along its entire length and, thanks to the surfaces (40, 41) for stopping the seat (24, 25), allows the wheel to be provided with increased stiffness. The invention also concerns a spoked bicycle wheel comprising such a hub.

Description

technical field [0001] The invention relates to a hub for a spoked bicycle wheel. The invention also relates to a spoked bicycle wheel comprising such a hub. Background technique [0002] As is known, a bicycle wheel mainly consists of a hub, a rim, and a plurality of spokes, the hub is intended to be rotatably coupled to a bicycle frame, a tire is mounted on the rim, and the spokes are between corresponding seats of the hub and the rim stretched and stretched. [0003] Wheel stiffness is of particular importance, especially in the field of high performance bicycle wheels. In fact, a stiff wheel has many advantages, including: it is more stable and easy to maneuver when making turns and in more dynamic conditions, and it is more responsive when accelerating and braking, which improves transmission efficiency. Spokes are inherently flexible and thus cannot in themselves ensure good rigidity of the wheel. [0004] In order to improve the rigidity of the wheel, new spoke ar...
