Description

ROUE DE TYPE ROUE DE VELO A RAYONS ET, MOYEU PERMETTANT  WHEEL TYPE BICYCLE WHEEL WITH RAYS AND HOLES FOR PERMITTING
D'EQUIPER LADITE ROUE  TO EQUIP THIS WHEEL
L'invention concerne une roue de type roue de vélo à rayons et le moyeu permettant d'équiper ladite roue. The invention relates to a spoked bicycle wheel type wheel and the hub for fitting said wheel.
L'invention s'applique aux roues de vélo ou à tout moyen de locomotion comportant des roues avec rayons.  The invention applies to bicycle wheels or any means of locomotion comprising wheels with spokes.
Une roue de vélo comporte de manière classique, une jante, un moyeu avec un axe correspondant à l'axe de la roue ainsi qu'un agencement de rayons permettant de relier la jante au moyeu, les rayons étant par l'une de leur extrémité fixés sur les flasques (ou bords) droite et gauche du moyeu et par l'autre extrémité à la bordure intérieure de la jante. Les rayons permettent de conférer de la rigidité à la roue et de transmettre le couple exercé sur l'axe lorsque le cycliste pédale. L'agencement des rayons est classiquement le même sur chaque flasque du moyeu mais il peut être différent, en particulier sur la roue arrière. Il est en effet, connu aujourd'hui, afin d'améliorer les performances, par exemple pour des vélos de course, que la roue arrière comporte un agencement de rayons différent sur chaque flasque du moyeu.  A bicycle wheel comprises conventionally, a rim, a hub with an axis corresponding to the axis of the wheel and a spoke arrangement for connecting the rim to the hub, the spokes being at one of their ends. attached to the right and left flanges (or edges) of the hub and the other end to the inner edge of the rim. The spokes make it possible to impart rigidity to the wheel and to transmit the torque exerted on the axle when the cyclist is pedaling. The arrangement of spokes is conventionally the same on each flange of the hub but it may be different, especially on the rear wheel. It is indeed, known today, to improve performance, for example for racing bikes, the rear wheel has a different arrangement of spokes on each flange of the hub.
Il est existe aujourd'hui deux type d'agencement des rayons, un agencement dit rayonnage radial et un agencement dit rayonnage tangentiel.  Today there are two types of arrangement of spokes, a so-called radial shelving arrangement and an arrangement called tangential shelving.
Dans le rayonnage radial, les rayons sont disposés perpendiculairement à l'axe en direction de la jante. Et aucun rayon ne se croise. L'intérêt du rayonnage radial est la simplicité de montage, et surtout un gain de poids car les rayons sont plus courts. Mais la roue est moins confortable car les chocs sont transmis radialement. Ce rayonnage ne se rencontre que sur les roues avant, non motrices, et avec un freinage sur la jante. On n'utilise pas le rayonnage radial sur une roue arrière, car le couple de pédalage cisaillerait le rayon au niveau de sa tête.  In the radial racking, the spokes are arranged perpendicular to the axis in the direction of the rim. And no ray crosses. The advantage of radial shelving is the simplicity of assembly, and especially a weight saving because the rays are shorter. But the wheel is less comfortable because shocks are transmitted radially. This rack is only found on the front wheels, not driving, and with braking on the rim. The radial racking on a rear wheel is not used because the pedaling torque would shear the spoke at its head.
Dans le rayonnage tangentiel, les rayons partent tangentiellement au moyeu, tantôt vers la gauche, tantôt vers la droite et se croisent. Avec un rayonnage tangentiel, la puissance est transmise par une moitié des rayons.  In the tangential rack, the spokes start tangentially to the hub, sometimes to the left, sometimes to the right and intersect. With tangential shelving, the power is transmitted by half of the rays.
Ainsi, un rayonnage radial, aux rayons non croisés et perpendiculaires au moyeu, permet d'obtenir une roue très légère (peu de matière) et verticalement très rigide, au détriment du confort et de la souplesse.  Thus, a radial rack, with uncrossed spokes and perpendicular to the hub, provides a very light wheel (little material) and vertically very rigid, to the detriment of comfort and flexibility.
Cependant, pour transférer efficacement le couple du moyeu à la jante, comme c'est le cas avec les roues motrices ou les roues avec des freins à disque ou à tambour, on doit, pour une meilleure longévité, avoir un agencement de rayons inclinés sur les flasques du moyeu. Cela permet une meilleure capacité de couple (mais une rigidité verticale minimale). However, to effectively transfer the torque from the hub to the rim, as is the case with the drive wheels or wheels with disc brakes or drum, we must, for a better longevity, have an arrangement of inclined spokes on the flanges of the hub. This allows for better torque capacity (but minimal vertical stiffness).
Pour améliorer les performances des vélos, les fabricants ont rendu les vélos plus légers en utilisant des matériaux très résistants mécaniquement et à la fois très légers pour la fabrication des cadres. Il est de plus en plus fréquent maintenant de trouver des vélos fabriqués dans des alliages légers tels que les alliages en aluminium ou les alliages de titane ou de fibres de carbone.  To improve the performance of bicycles, manufacturers have made the bikes lighter by using mechanically very strong materials and at the same time very light for the manufacture of frames. It is becoming increasingly common now to find bikes made from lightweight alloys such as aluminum alloys or titanium alloys or carbon fibers.
Dans le but toujours d'améliorer les performances des vélos, il est connu aussi d'alléger encore plus les vélos en les équipant de jantes en alliage légers, alliage d'aluminium ou titane ou en matériau composite de carbone.  In order always to improve the performance of bicycles, it is also known to lighten up even more bikes by equipping them with light alloy wheels, aluminum alloy or titanium or carbon composite material.
Le problème qu'a cherché à résoudre le déposant est celui de l'amélioration des performances des vélos. Pour résoudre ce problème, le déposant a cherché dans une autre direction que celle de l'allégement du cadre ou des roues tout en ne négl igeant pas cet aspect. En effet, le déposant a cherché à amél iorer les performances des vélos en s'orientant vers une amélioration du rendement des roues elles mêmes au moyen de nouvelles structures. Le déposant a trouvé à l'issue de ses recherches, qu'un agencement de rayons particulier permettait d'améliorer de plus de 4% le rendement par rapport au résultat obtenu avec des roues existantes, c'est-à-dire que pour un même effort fourni par le cycliste, un vélo équipé de roues selon la présente invention, a un rendement d'au moins 4% supérieur. Des mesures de couples ont été faites avec la présente invention et ont révélé une amélioration du rendement allant de 4% à 8% par rapport aux roues de vélos existantes et en particulier par rapport aux roues à rayons.  The problem that the applicant has sought to solve is that of improving the performance of bicycles. To solve this problem, the applicant has sought in another direction than that of the lightening of the frame or the wheels while not neglecting this aspect. Indeed, the applicant has sought to improve the performance of bicycles by moving towards improving the efficiency of the wheels themselves by means of new structures. The applicant found at the end of his research, that a particular arrangement of spokes allowed to improve by more than 4% the yield compared to the result obtained with existing wheels, that is to say that for a same effort provided by the cyclist, a bicycle equipped with wheels according to the present invention, has a yield of at least 4% higher. Torque measurements have been made with the present invention and have revealed an efficiency improvement ranging from 4% to 8% over existing bicycle wheels and in particular with respect to the spoke wheels.
Le problème a été résolu au moyen d'une roue de type roue de vélo à rayons comprenant un nouvel agencement d'éléments de liaison entre jante et moyeu, cet agencement comportant au moins deux jeux d'au moins deux éléments de liaison jante -moyeu- jante se présentant sous forme de rayons en opposition ou de tiges , situés dans plans parallèles à l'axe de la roue et de part et d'autre de cet axe.  The problem has been solved by means of a spoked wheel-type wheel comprising a new arrangement of connection elements between rim and hub, this arrangement comprising at least two sets of at least two rim-motor binding elements. - Rim in the form of opposing spokes or rods, located in planes parallel to the axis of the wheel and on either side of this axis.
Selon un mode de réalisation, les éléments de liaison jante -moyeu- jante, forment des rayons en opposition deux à deux dont l'une des extrémités est attachée à la jante et dont l'autre extrémité est attachée au moyeu.  According to one embodiment, the rim-hub coupling members form two-to-two opposed spokes, one end of which is attached to the rim and the other end of which is attached to the hub.
Selon un autre mode de réalisation, les éléments de liaison jante -moyeu- jante sont formés d'un élément continu constitué d'u ne tige dont les deux extrémités sont attachées à la jante et dont une partie médiane est attachée au moyeu. Dans ce mode de réalisation chaque élément de liaison jante -moyeu- jante est constitué d'une seule tige au lieu de deux rayons en opposition comme dans le premier mode. According to another embodiment, the rim-hub coupling members are formed of a continuous element consisting of a rod whose two ends are attached to the rim and a middle portion of which is attached to the hub. In this embodiment each rim connecting element -moyeu- rim consists of a single rod instead of two rays in opposition as in the first mode.
On entend par rayons en opposition, des rayons qui partent dans des directions opposées à 180° du moyeu en direction de la jante. La roue est ainsi équipée d'un agencement de rayons opposés deux à deux formant un angle de 180° par rapport à un plan radial du moyeu.  Rays in opposition are understood to mean spokes which start in opposite directions at 180 ° from the hub towards the rim. The wheel is thus equipped with an arrangement of opposing radii in pairs forming an angle of 180 ° with respect to a radial plane of the hub.
On entend dans la suite par flasque gauche et flasque droite respectivement le côté gauche et le coté droit du moyeu.  The left flange and right flange respectively are understood to mean the left side and the right side of the hub.

Figure 7 shows the diagram according to a front view of a wheel according to a second example of the invention. By convention one designates left side, the first plane on the figures and by right side, the back plane.
En outre, les mêmes éléments représentés sur les figures ont les mêmes références.  In addition, the same elements shown in the figures have the same references.
Dans tous les exemples et variantes de réalisation de l'invention, la roue comprend une jante 200, un moyeu 10 avec un axe 100 correspondant à l'axe de la roue. Le moyeu comporte une flasque gauche 1 1 et une flaque droite 12. La roue comporte en outre un agencement d'éléments de liaison jante - moyeu - jante sur les deux flasques du moyeu.  In all the examples and variants of the invention, the wheel comprises a rim 200, a hub 10 with an axis 100 corresponding to the axis of the wheel. The hub comprises a left flange 1 1 and a right sponge 12. The wheel further comprises an arrangement of rim - hub - rim connection elements on the two flanges of the hub.
Sur l'exemple illustré par les figures 2 et 3 l'agencement comprend deux jeux de deux éléments de liaison jante - moyeu - jante, dans le quel lesdits éléments de chaque jeu sont dans des plans situés de part et d'autre de l'axe de la roue et parallèles audit axe et dans lequel chaque éléments de liaison jante - moyeu - jante comprend deux rayons en opposition ayant chacun une extrémité attaché à la jante et une extrémité attaché au moyeu. Les rayons sont dans le prolongement l'un de l'autre dans des directions à 180°.  In the example illustrated in FIGS. 2 and 3, the arrangement comprises two sets of two rim-hub-rim connection elements, in which said elements of each set are in planes situated on either side of the rim. wheel axis and parallel to said axis and wherein each rim - hub - rim connecting member comprises two opposed spokes each having one end attached to the rim and one end attached to the hub. The spokes are in the extension of each other in directions at 180 °.
Sur l'exemple illustré par la figure 7, l'agencement comprend trois jeux de deux éléments de liaison jante - moyeu - jante sur les deux flasques du moyeu 10, dans lequel chaque élément de liaison jante - moyeu - jante comprend une tige ayant ses deux extrémités attachées à la jante et une partie centrale attachée au moyeu.  In the example illustrated in FIG. 7, the arrangement comprises three sets of two rim - hub - rim connecting elements on the two flanges of the hub 10, in which each rim - hub - rim connection element comprises a rod having its two ends attached to the rim and a central portion attached to the hub.
Dans les exemples décrits ci-après, l'agencement des éléments de liaison est décalé d'un coté de moyeux par rapport à celui de l'autre côté afin que tous les points d'attache (ou liaisons) des éléments à la jante soient répartis de manière équilibrée vis-à-vis des couples de forces exercés.  In the examples described below, the arrangement of the connecting elements is offset on one side of the hubs relative to the other side so that all the points of attachment (or links) of the elements to the rim are distributed in a balanced manner vis-à-vis the pairs of forces exerted.
Premier exemple : figures 2 et 3.  First example: Figures 2 and 3.
Dans cet exemple de réal isation, la roue comporte un agencement d'éléments de liaison jante - moyeu - jante, identique sur les deux flasques du moyeu. Cet agencement comporte précisément dans cet exemple, deux jeux de deux éléments de liaison jante - moyeu - jante, le jeu d'éléments de liaison 51 -52 ; 53-54 et le jeu d'éléments de liaison 55-56 ; 57-58 pour le coté gauche et, pour le coté droit, le jeu d'élément de liaison 59-60 ; 61 -62 et le jeu d'élément de liaison 63-64 ; 65-66. Pour chaque flasque, chaque élément de liaison de l'un des jeux, croise perpendiculairement un élément de l iaison de l'autre jeu. En outre, les éléments de liaison de chaque jeu, sont dans des plans parallèles à l'axe de la roue, et situés de part et d'autre de cet axe. Ainsi, l'agencement proposé selon cet exemple, comprend pour chaque jeu, des éléments de liaison jante- moyeu- jante dans lequel chaque élément comprend deux rayons en opposition, ces rayons en opposition sont situés sur des plans parallèles de part et d'autre à l'axe de la roue et parallèles audit axe 100. En outre les rayons sont attachés sur les flasques du moyeu dont la forme permet une attache éloignée de l'axe, par rapport à des rayons montés sur des roues classiques. Selon l'agencement proposé, les rayons en opposition sont ainsi éloignés de l'axe d'une distance supérieure à la distance rencontrée habituellement pour des roues existantes. En effet, cette distance est sensiblement égale à 71 mm pour une jante de profil A égal à 38 mm (c'est-à-dire une largeur A de 38 mm) ou égale à 75 mm pour une jante de profil égal à 27 mm ou de 60 mm pour une jante de profil égal à 88 mm, alors que, classiquement, cette distante est de l'ordre de 20 à 30 mm. Avec les roues existantes, le montage des rayons en opposition ne pourrait se faire que par rapport à l'axe du moyeu, et ceci n'est pas envisageable et encore moins envisageable sur les roues arrière en raison du couple de torsion qui s'ajouterait à la force liée au pédalage. In this embodiment, the wheel comprises an arrangement of connecting rim - hub - rim, identical on the two flanges of the hub. This arrangement comprises precisely in this example, two sets of two connecting elements rim - hub - rim, the set of connecting elements 51 -52; 53-54 and the linkage set 55-56; 57-58 for the left side and, for the right side, the linkage set 59-60; 61-62 and 63-64 link set; 65-66. For each flange, each connecting element of one of the games, crosses perpendicularly one element of the iaison of the other game. In addition, the connecting elements of each game, are in planes parallel to the axis of the game. wheel, and located on both sides of this axis. Thus, the arrangement proposed according to this example comprises, for each set, rim-hub connection elements in which each element comprises two opposed spokes, these opposing spokes are located on parallel planes on either side. at the axis of the wheel and parallel to said axis 100. In addition the spokes are attached to the flanges of the hub whose shape allows a fastener remote from the axis, relative to spokes mounted on conventional wheels. According to the proposed arrangement, the opposing rays are thus remote from the axis by a distance greater than the distance usually encountered for existing wheels. Indeed, this distance is substantially equal to 71 mm for a profile rim A equal to 38 mm (that is to say a width A of 38 mm) or equal to 75 mm for a profile rim equal to 27 mm or 60 mm for a profile rim equal to 88 mm, whereas, conventionally, this distance is of the order of 20 to 30 mm. With the existing wheels, the mounting of the spokes in opposition could be done only with respect to the axis of the hub, and this is not possible and even less conceivable on the rear wheels because of the torque of torsion that would be added the force related to pedaling.
Ainsi, l'attachement des rayons sur le moyeu est décalé par rapport à l'axe de la roue et ceci est obtenu avantageusement par la forme des flasques. Le moyeu possède des flasques présentant un diamètre ou largeur plus grand que le diamètre des moyeux habituels.  Thus, the attachment of the spokes on the hub is offset relative to the axis of the wheel and this is advantageously obtained by the shape of the flanges. The hub has flanges having a diameter or width larger than the diameter of the usual hubs.
De manière plus détaillée, les figures 2 et 3 représentent une roue en vue de face comportant un axe 100, une jante : 200, une bordure intérieure de jante 201 , un moyeu 1 0, une flasque gauche 1 1 du moyeu 1 1 , une flasque droite 12 du moyeu. Sur cet exemple de réalisation, chaque flasque comporte une partie circulaire montée sur l'axe de la roue et muni d'ailes référencées, pour la flasque coté gauche : 1 10-1 1 1 -1 12- 1 13 et pour les ailes coté droit : 120-121 -122-123.Les rayons sont attachés aux extrémités des ailes de chaque flasque. Les points d'attache sont éloignés de l'axe. Cet éloignement est sensiblement de 60 mm à 75 mm selon la largeur choisie pour la jante de la roue alors qu'il est de 20 à 30 mm classiquement.  In more detail, FIGS. 2 and 3 show a wheel in front view having an axis 100, a rim: 200, an inner rim edge 201, a hub 1 0, a left flange 1 1 of the hub 1 1, a right flange 12 of the hub. In this exemplary embodiment, each flange comprises a circular portion mounted on the axis of the wheel and provided with referenced flanges, for the flange on the left side: 1 10-1 1 1 -1 12-1 13 and for the wings on the side right: 120-121 -122-123.The spokes are attached to the ends of the wings of each flange. The attachment points are far from the axis. This distance is substantially 60 mm to 75 mm depending on the width chosen for the rim of the wheel while it is 20 to 30 mm conventionally.
Les rayons côté gauche sont référencés : 51 -52 ; 53-54 ; 55-56 ; 57-58 et les rayons coté droit sont référencés : 59-60 ; 61 -62 ; 63-64 ; 65-66, cette numérotation indique que les couples sont des rayons en opposition : comme par exemple, le rayon 51 est en opposition avec le rayon 52 ; le rayon 53 est en opposition avec le rayon 54 etc. Chaque rayon coté gauche est attaché par un point d'attache 41 sur une aile de la flasque gauche et par un point d'attache 20 sur le bord intérieur de la jante. Pour simplifier, tous les points d'attache des rayons à la bordure intérieure de la jante 201 , que ces rayons partent de la flasque gauche ou droite, portent la même référence 20. Lesdits points d'attache sont réalisés par exemple de manière classique et connue à savoir par un filetage sur l'extrémité des rayons coopérant avec une vis de réglage de la tension dans la jante. La liaison rayon jante est ainsi démontable. The radii on the left side are referenced: 51-52; 53-54; 55-56; 57-58 and the right-hand rays are referenced: 59-60; 61-62; 63-64; 65-66, this numbering indicates that the pairs are opposite rays: as for example, the ray 51 is in opposition with the radius 52; the radius 53 is in opposition with the ray 54 etc. Each left-side spoke is attached by an attachment point 41 to a wing of the left flange and an attachment point 20 to the inner edge of the rim. For simplicity, all the attachment points of the spokes to the inner edge of the rim 201, that these rays start from the left or right flange, have the same reference 20. Said attachment points are made for example in a conventional manner and known namely by a thread on the end of the spokes cooperating with a tension adjusting screw in the rim. The rim spoke connection is thus removable.
Chaque rayon coté gauche est fixé par un point de fixation 42 sur une aile de la flasque gauche. Tous les points d'attache des rayons aux ailes ont cette même référence.  Each radius on the left side is fixed by an attachment point 42 on a wing of the left flange. All the points of attachment of the spokes to the wings have this same reference.
Le rayon 51 est fixé sur l'aile 1 10 et le rayon 52 est fixé sur cette même aile 1 10. Le rayon 53 est fixé sur l'aile 1 12 et le rayon 54 est fixé sur cette même aile 1 12.  The spoke 51 is fixed on the wing 1 10 and the radius 52 is fixed on the same wing 1 10. The spoke 53 is fixed on the wing 1 12 and the spoke 54 is fixed on the same wing 1 12.
Le rayon 55 est fixé sur l'aile 1 13 et le rayon 56 est fixé sur cette même aile The radius 55 is fixed on the wing 1 13 and the radius 56 is fixed on the same wing
1 13. Le rayon 57 est fixé sur l'aile 1 1 1 et le rayon 58 est fixé sur cette même aile 1 1 1 . 13. The radius 57 is fixed on the wing 1 1 1 and the radius 58 is fixed on the same wing 1 1 1.
Chaque rayon coté droit est fixé par un point de fixation 41 sur une aile de la flasque droite. Tous les points d'attache des rayons aux ailes ont la même référence.  Each radius on the right side is fixed by an attachment point 41 on a wing of the right flange. All points of attachment of the spokes to the wings have the same reference.
Le rayon 59 est fixé sur l'aile 22 et le rayon 60 est fixé sur cette même aile 122. Le rayon 61 est fixé sur l'aile 121 et le rayon 62 est fixé sur cette même aile 121 .  The spoke 59 is fixed on the wing 22 and the spoke 60 is fixed on the same wing 122. The spoke 61 is fixed on the wing 121 and the spoke 62 is fixed on the same wing 121.
Le rayon 63 est fixé sur l'aile 120 et le rayon 64 est fixé sur cette même aile 120. Le rayon 65 est fixé sur l'aile 123 et le rayon 66 est fixé sur cette même aile 123.  The spoke 63 is fixed on the wing 120 and the spoke 64 is fixed on the same wing 120. The spoke 65 is fixed on the wing 123 and the spoke 66 is fixed on the same wing 123.
L'agencement décrit, peut comporter en outre des rayons supplémentaires. Sur le coté gauche les rayons supplémentaires sont référencés 71 -72 ; 73-74 et sur le coté droit, les rayons supplémentaires sont référencés 75-76 ; 77-78. Tous ces rayons supplémentaires ont une attache radiale à l'axe en direction de la jante. Avantageusement ces rayons supplémentaires sont attachés selon une médiane entre chaque aile du moyeu. Ces rayons supplémentaires sont plus courts que les rayons attachés aux extrémités des ailes du moyeu. L'ajout de ces rayons permet de renforcer la rigidité.  The arrangement described may further include additional radii. On the left side the additional spokes are referenced 71 -72; 73-74 and on the right side, the additional shelves are referenced 75-76; 77-78. All these additional spokes have a radial attachment to the axis in the direction of the rim. Advantageously, these additional spokes are attached along a median between each wing of the hub. These additional spokes are shorter than the spokes attached to the ends of the hub flanges. The addition of these spokes can strengthen the rigidity.
Le tableau suivant est donné à titre d'exemple pour plusieurs largeurs de jante (en cm). Dans ce tableau la distance A correspond à la largeur de la jante, la distance B correspond à la longueur d'un rayon supplémentaire reliant un point médian 43 entre deux ailes (figure 2, figure 3 ou figure 4) et la distance C correspond à la longueur des rayons en opposition. Comme par exemple 51 ou 52. The following table is given as an example for several rim widths (in cm). In this table the distance A corresponds to the width of the rim, the distance B corresponds to the length of an additional radius connecting a midpoint 43 between two wings (Figure 2, Figure 3 or Figure 4) and the distance C corresponds to the length of the spokes in opposition. As for example 51 or 52.
Les figures 4, 5 et 6 et illustrent trois variantes de réalisation du moyeu. Figures 4, 5 and 6 and illustrate three embodiments of the hub.
Sur le figure 4, le moyeu 10 comporte, selon une première variante, deux flasques constituées chacune, d'une pièce 1 1 , 1 2 en forme de croix munie de quatre ailes 1 1 0 à 1 1 3 ; 122 à 123. L'extrémité de chaque aile comporte deux perforations 41 sur la flasque gauche et 42 sur la flasque droite. Ces perforations permettent de passer les rayons au montage de la roue et de les attacher au moyeu. Les rayons sont placés en opposition deux à deux, tangentiellement à l'axe du moyeu. Les rayons sont bloqués après leur passage et cela de manière connue, par leur extrémité qui présente une tête aplatie. Les rayons sont ainsi attachés au moyeu. Chaque pièce en croix 1 1 et 12 comporte en outre dans les creux entre deux ailes, une perforation 43 permettant de passer les rayons supplémentaires, fixés radialement à la jante 200.  In Figure 4, the hub 10 comprises, in a first variant, two flanges each consisting of a part 1 1, 1 2 in the form of a cross provided with four wings 1 1 0 to 1 1 3; 122 to 123. The end of each wing has two perforations 41 on the left flange and 42 on the right flange. These perforations make it possible to pass the spokes to the assembly of the wheel and to attach them to the hub. The spokes are placed in opposition two by two, tangentially to the axis of the hub. The spokes are blocked after their passage and this in known manner, by their end which has a flattened head. The spokes are thus attached to the hub. Each crosspiece 1 1 and 12 further comprises in the recesses between two wings, a perforation 43 for passing the additional spokes, radially fixed to the rim 200.
Les flasques du moyeu sont constituées d'une pièce unique réalisée en forme de croix par usinage dans un matériau résistant mécaniquement comme par exemple un alliage d'aluminium tel que par exemple de l'aluminium Zycral . Le diamètre des flasques est calculé en fonction du profil de la jante de façon que chaque rayon soit dans le prolongement d'un autre rayon avec un angle de 180°. Cette pièce en forme de croix permet de positionner les rayons en parfaite opposition au niveau tangentiel du moyeu et non pas en son centre. Ainsi, les rayons peuvent être positionnés en opposition deux à deux, tout en formant une liaison jante -moyeu- jante éloignée du centre c'est-à-dire éloignée de l'axe.  The flanges of the hub consist of a single piece made in the form of cross machining in a mechanically resistant material such as for example an aluminum alloy such as for example Zycral aluminum. The diameter of the flanges is calculated according to the profile of the rim so that each spoke is in the extension of another radius with an angle of 180 °. This cross-shaped piece makes it possible to position the spokes in perfect opposition to the tangential level of the hub and not at its center. Thus, the spokes may be positioned in opposition two by two, while forming a rim-hub connection remote from the center, that is to say away from the axis.
Sur la figure 5, on a représenté la réalisation d'une flasque 41 ou 42, d'un moyeu 10 selon une deuxième variante. Cette flasque est vue de face. Dans cet exemple, la flasque 1 1 (ou 12) comporte une pièce circulaire 51 1 (ou 512) comportant quatre ailettes 210 à 213 radialement opposées. Chaque ailette comporte deux perforations 41 (ou 42) permettant le passage chacune d'un rayon destiné à être en opposition et tangentiel à l'axe. Les rayons 551 à 557 sont passés chacun à travers une perforation et attachés ainsi au moyeu. Les rayons possèdent à cette fin une extrémité aplatie qui les retient après passage dans la perforation. Au montage, les rayons sont orientés de manière à être en opposition deux à deux et tangentiels à l'axe du moyeu et au moyeu. In Figure 5, there is shown the embodiment of a flange 41 or 42, a hub 10 according to a second variant. This flask is seen from the front. In this example, the flange 1 1 (or 12) has a circular part 51 1 (or 512) having four fins 210 to 213 radially opposite. Each fin comprises two perforations 41 (or 42) allowing the passage each of a radius intended to be in opposition and tangential to the axis. The spokes 551 to 557 are each passed through a perforation and thus attached to the hub. The rays possess for this purpose a flattened end which retains them after passing through the perforation. On assembly, the spokes are oriented so as to be in opposition two by two and tangential to the axis of the hub and the hub.
Sur la figure 6 on a représenté la réalisation d'une flasque 41 ou 42 d'un moyen selon un troisième exemple. Cet exemple est similaire à l'exemple de la figure 5. La flasque est vue de face et comporte une pièce circulaire 61 1 (ou 612) munie d'extensions 651 à 657. Ces extensions constituent des rayons tangentiels à l'axe du moyeu. Les extensions sont réalisées en périphérie de la pièce centrale de manière à former deux jeux de deux paires de rayons, les rayons de chaque paire étant en opposition.  FIG. 6 shows the embodiment of a flange 41 or 42 of a means according to a third example. This example is similar to the example of FIG. 5. The flange is seen from the front and comprises a circular part 61 1 (or 612) provided with extensions 651 to 657. These extensions constitute tangential radii to the axis of the hub. . The extensions are made on the periphery of the central piece so as to form two sets of two pairs of spokes, the spokes of each pair being in opposition.
Dans ces deux variantes, les rayons peuvent être positionnés en opposition deux à deux, tout en formant une liaison jante -moyeu- jante éloignée du centre c'est-à-dire éloignée de l'axe. Seule cette configuration permet de garantir un parfait équilibre des tensions et résister aux forces induites par le pédalage.  In these two variants, the spokes can be positioned in opposition two by two, while forming a rim-hub connection away from the center, that is to say away from the axis. Only this configuration ensures a perfect balance of tension and resist the forces induced by pedaling.
Deuxième exemple : figure 7.  Second example: Figure 7.
Dans cet exemple de réalisation, la roue comporte trois jeux d'éléments de liaison dans lesquels chaque élément de liaison comporte une tige référencée respectivement 751 à 756 pour la flasque 71 1 et 757 à 762 pour l'autre flasque 712 (non visible). Les tiges sont attachées par leurs extrémités à la bordure 201 de la jante 200. Chaque tige comporte un filetage à leur extrémité qui coopère avec un filetage à chaque point d'attache 20 sur la jante. Chaque tige 751 à 756 et 757 à 762 comporte en outre une partie médiane attachée sur les flaques respectivement 71 1 et 712 du moyeu 10.  In this exemplary embodiment, the wheel comprises three sets of connecting elements in which each connecting element comprises a rod respectively referenced 751 to 756 for the flange 71 1 and 757 to 762 for the other flange 712 (not visible). The rods are attached at their ends to the rim 201 of the rim 200. Each rod has a thread at their end which cooperates with a thread at each attachment point 20 on the rim. Each rod 751 to 756 and 757 to 762 further comprises a central portion attached to the pans 71 1 and 712 respectively of the hub 10.
Les flasques 71 1 (ou 712) sont constituée avantageusement par une pièce de forme hexagone régulier. Chaque coté de la pièce hexagonale comporte sur ses six bordures une rigole 713 ou logement, destinée à recevoir une tige. La partie médiane pour chaque tige 751 à 756 et 757 à 762, est logée dans une rigole et collée. La jante n'est plus tirée mais poussée par chaque point de l'hexagone avec une continuité de mouvement qui supprime les temps morts.  The flanges 71 1 (or 712) are advantageously constituted by a piece of regular hexagon shape. Each side of the hexagonal part has on its six borders a channel 713 or housing for receiving a rod. The middle part for each rod 751 to 756 and 757 to 762, is housed in a channel and glued. The rim is no longer pulled but pushed by each point of the hexagon with a continuity of movement which eliminates the timeouts.
Pour augmenter la rigidité des tiges, des ligatures 714 sur les rayons qui se croisent sont prévues.  To increase the rigidity of the stems, ligations 714 on the intersecting rays are provided.
De préférence les tiges 751 à 756 et 757 à 762 sont creuses. Tout comme dans le premier exemple, la roue ainsi réal isée permet d'annuler l'effet traction-compression qui ovalise habituellement les roues et la garde ainsi dans sa forme parfaite d'origine sans aucune déformation. L'utilisation des tiges et d'un moyeu en composite carbone permet en outre une réduction du poids significative, l'agencement proposé. Preferably the rods 751 to 756 and 757 to 762 are hollow. As in the first example, the wheel thus realizes allows to cancel the traction-compression effect which usually ovalises the wheels and keeps it in its original perfect shape without any deformation. The use of the rods and carbon composite hub also allows a significant weight reduction, the proposed arrangement.
Une telle roue fabriquée en composite de carbone répond aux besoins actuels d'amélioration des performances par la réduction du poids avec en plus une amélioration du rendement apportée par l'agencement proposé qu i permet d'appliquer de fortes tension (synonyme d'augmentation du rendement),  Such a wheel made of carbon composite meets the current needs for improving performance by reducing weight with the addition of an improvement in the efficiency provided by the proposed arrangement which makes it possible to apply high tension (synonymous with increasing return)
En outre, la roue comporte des tiges démontables et les tensions peuvent être réglées grâce aux extrémités qui comportent un filetage coopérant avec des vis dans la jante. Les vis sont de préférence en titane. Les tiges peuvent en effet être démontées par décollage de leur partie centrale et dévissage des extrémités.  In addition, the wheel has removable rods and the tensions can be adjusted through the ends which have a thread cooperating with screws in the rim. The screws are preferably made of titanium. The rods can indeed be removed by taking off their central part and unscrewing the ends.
Cet exemple de réalisation permet d'avoir une roue en composite de carbone démontable et par conséquent réparable, à rendement élevé.  This exemplary embodiment makes it possible to have a dismountable and therefore repairable carbon composite wheel with high efficiency.
Dans tous les exemples décrits les flasques des moyeux peuvent être obtenues en une seule opération de moulage par injection ou par découpage à la presse. La roue selon l'invention est particulièrement destinée au montage de roues de vélos haut de gamme.  In all the examples described the flanges of the hubs can be obtained in a single operation of injection molding or die cutting. The wheel according to the invention is particularly intended for mounting high-end bicycle wheels.
