Wheel of the spoked bicycle wheel type, and hub with which said wheel can be fitted
A wheel of the bicycle wheel type includes a rim ( 200 ), a hub ( 10 ) with an axis ( 100 ) corresponding to the axis of the wheel, the hub including a left flange ( 11 ) and a right flange ( 12 ). The wheel includes an arrangement of rim-hub-rim connecting elements on at least one flange of the hub, which includes at least two sets of at least two rim-hub-rim connecting elements (( 51 - 52; 53 - 54 ); ( 55 - 56; 57 - 58 )), in the form of opposing spokes or rods, and in which the elements of each set are in planes situated on either side of the axis of the wheel and parallel to the axis.
1. A wheel of a bicycle wheel type, comprising:
a rim;
a hub with an axle corresponding to an axle of the wheel, said hub comprising a left flange and a right flange; and
a system of rim-hub-rim connecting elements on the flanges of the hub, said system comprising at least two sets that are mutually perpendicular of at least three rim-hub-rim connecting elements, said at least three rim-hub-rim connecting elements of each set being in planes located on either side of the axle of the wheel and parallel to said axle of the wheel, each rim-hub-rim connecting element comprising one of (i) two opposing spokes each having one end attached to the rim and one end attached to the hub, and (ii) a rod having both of its ends attached to the rim and a central portion attached to the hub, so that each set of two connecting elements of the flanges includes at least four opposing spokes in pairs, each of the at least four spokes having a first end attached to the flange or to the other flange of the hub and a second end attached to the rim,
wherein the system of rim-hub-rim connecting elements is identical on the right and left flanges of the hub, but offset in angle about the axle of the wheel so that the rim-hub-rim connecting elements are not facing one another,
wherein each flange includes a single part comprising a central portion placed on the axle of the wheel having four extensions in the form of vanes forming a cross and medial portions between adjacent vanes, each vane comprising, at its end opposite to the axle of the wheel, perforations for attaching opposing spokes allowing remote positioning of the connecting elements relative to the axle of the wheel, and
at least one rib-hub-rim connecting element is attached to at least one of the flanges at a medial portion of the flange.
2. The bicycle wheel according to claim 1 , wherein the system of rim-hub-rim connecting elements comprises two sets of two rim-hub-rim connecting elements.
3. The bicycle wheel according to claim 1 , wherein the remote positioning of the connecting elements relative to the axle of the wheel on said flanges is from 60 mm to 75 mm, 60 mm for a wheel having a rim profile equal to 88 mm, and 75 mm for a rim profile equal to 27 mm.
4. The bicycle wheel according to claim 1 , wherein the ends of the spokes or of the rods attached to the rim are threaded, allowing attachment or detachment of said spokes or rods.
5. The bicycle wheel according to claim 1 , wherein the hub comprises an attachment system configured to cooperate with the spokes or the rods to allow attachment or detachment of said spokes or rods.
6. The bicycle wheel according to claim 1 , wherein the rim, the hub, the spokes and the rods are made of light alloy or of carbon composite material.
7. The bicycle wheel according to claim 1 , wherein the spokes and the rods are hollow tubes.
