Abstract

Systems to make it easier to put away and/or store and/or remove and refit wheels quickly for cleaning, maintaining or modifying the type of use. The present invention relates to systems operating together or separately on a bicycle or motorized cycle, and characterized in that they allow the wheels to be put away and/or stored in a minimum of space and/or removed quickly and possibly refitted almost instantly for ease of cleaning, ease of maintenance (for example in the event of a puncture) or for quickly changing the type of use (changing from mountain bike to hybrid bike for example). The rear wheel (3) and/or the front wheel (2) is(are) mounted with overhang on, respectively, a rear hub (118) with built-in gears; and a front hub with built-in dynamo, said rear wheel (3) and/or said front wheel (2) now being removed transversely (x-y) rather than in the longitudinal vertical mid-plane. A frame (9) and/or a front fork (4) optimizes said overhanging mounting. The systems according to the invention are particularly intended for bicycles and motorized cycles that use rear hubs with built-in gears.

Description

MOYEU ARRIERE A VITESSES INTEGREES ET MOYEU AVANT A DYNAMO INTEGREE PERMETTANT UN MONTAGE TRANSVERSAL DES ROUES POUR UN VELO OU VELOMOTEURREAR HUB WITH INTEGRATED SPEEDS AND FRONT HUB WITH INTEGRATED DYNAMO FOR TRANSVERSE MOUNTING OF WHEELS FOR BIKE OR VELOMOTOR
La présente invention concerne des systèmes fonctionnant ensemble ou séparément sur un vélo ou un cyclomoteur caractérisés en ce qu'ils permettent très rapidement le rangement et/ou le stockage dans un minimum d'espace et/ou le démontage et le remontage éventuel quasi instantané des roues pour nettoyer aisément, entretenir 5 facilement (crevaison par exemple) ou modifier à volonté le type d'utilisation (VTT en VTC par exemple).The present invention relates to systems operating together or separately on a bicycle or a moped characterized in that they allow very quickly storage and / or storage in a minimum of space and / or disassembly and possible reassembly almost instantaneous wheels to easily clean, maintain 5 easily (puncture for example) or change at will the type of use (VTT VTC for example).
Concernant le système selon l'invention de démontage des roues et notamment de la roue arrière, traditionnellement quand le système pour changer de vitesse est un moyeu arrière à vitesses intégrées tel que par exemple : « Shimano (Nexus) » (marque déposée) ouRegarding the system according to the invention for disassembling the wheels and in particular the rear wheel, traditionally when the system for shifting is a rear hub with integrated speeds such as for example: "Shimano (Nexus)" (registered trademark) or
10 « Sram » (marque déposée) ou « Sturmey Archer » (marque déposée) ou « Rohloff » (marque déposée) ... permettant environ de 3 à 14 vitesses selon les marques et les modèles ; le montage de tous ces moyeux (et donc des roues forcément puisque la jante et le dit moyeu sont assemblés de façon solidaires durable ) se fait sur le cadre ou un bras oscillant (en cas de suspension arrière) ayant obligatoirement une forme de fourche10 "Sram" (registered trademark) or "Sturmey Archer" (registered trademark) or "Rohloff" (registered trademark) ... allowing about 3 to 14 speeds depending on brands and models; the assembly of all these hubs (and therefore the wheels necessarily since the rim and the said hub are assembled durably) is done on the frame or an oscillating arm (in case of rear suspension) having obligatorily a form of fork
15 supportant les deux extrémités de l'axe des dits moyeux. Ce type de montage entre bras de fourche nécessite impérativement au moins la dépose de la chaîne (ou de la courroie) ou le désacouplage d'un couple conique pour un arbre. Retirer la roue arrière est déjà rébarbatif avec un dérailleur classique, mais il devient carrément rebutant avec les dits moyeux à vitesses intégrées surtout si l'élément de transmission (chaîne le plus souvent) est enfermé 0 dans une sorte de carter en tôle ! Cet ennui majeur freine l'utilisation et donc les ventes des vélos dits (à tort) propres et sans entretien tel que les « city bike » par exemple. Concernant le système selon l'invention de modifier la position du porte bagage (ou panier) avant, pour permettre d'y installer un porte bébé (ou un panier), les fixations actuelles des dits portes bagages ne permettent pas d'optimiser l'emplacement de l'enfant 5 ou du panier ce qui nuit à un bon équilibre du cycle en plus de l'aspect encombrant généré.15 supporting both ends of the axis of said hubs. This type of mounting between fork arm requires at least the removal of the chain (or belt) or the decoupling of a conical torque for a shaft. Removing the rear wheel is already boring with a conventional derailleur, but it becomes downright discomfort with said hubs integrated speeds especially if the transmission element (chain most often) is enclosed 0 in a kind of sheet metal housing! This major boredom slows down the use and therefore the sales of so-called (wrongly) clean and maintenance-free bicycles such as the "city bike" for example. Regarding the system according to the invention to change the position of the luggage rack (or basket) before, to allow to install a baby carrier (or basket), the current fixings of said luggage doors do not optimize the location of the child 5 or basket which affects a good balance of the cycle in addition to the cumbersome appearance generated.
Les systèmes selon l'invention permettent de remédier à Ces inconvénients. Ils comportent en effet selon une première caractéristique, un montage dit à porte à faux du moyeu à vitesses intégrées qui devient ainsi un moyeu fusée avec démontage de la roue par le coté et non plus dans le plan vertical médian longitudinal du cycle. Selon une deuxième 0 caractéristique le porte bagage avant bascule d'avant en arrière offrant ainsi une position plutôt centré au milieu du guidon avec le panier légèrement en avant de l'axe de direction et plutôt centré au milieu du guidon avec le porte bébé légèrement en arrière du même axe de direction, avec l'enfant faisant préférentiellement face au cycliste. Selon des modes particuliers de réalisation : 5 - la roue arrière et la roue avant seront identique et donc interchangeable rapidement. - le pédalier avant, le moyen de transmission (chaîne ou courroie ou arbre), le moyeu à vitesses intégrées dans sa partie réceptrice du mouvement de transmission (environ moitié droite normàiernent), constituent un ensemble entièrement cartérisé et donc parfaitement étanche iήtédeurement et extérieurement ce qui permet une lubrification éventuelle avec de l'huile extrêmement fluide ce qui améliore d'autant le rendement mécanique. La roue arrière et éventuellement les moyens de freinage complètent cet ensemble pour constituer ce que j'appelle un module de transmission.The systems according to the invention make it possible to remedy these drawbacks. They have in fact according to a first feature, a so-called mounting overhang of the hub with integrated speeds which thus becomes a rocket hub with disassembly of the wheel by the side and not in the longitudinal median vertical plane of the cycle. According to a second characteristic 0 the front luggage rack rocking back and forth thus providing a rather centered position in the middle of the handlebar with the basket slightly forward of the steering axis and rather centered in the middle of the handlebar with the baby carrier slightly in rear of the same direction axis, with the child preferentially facing the cyclist. According to particular embodiments: 5 - the rear wheel and the front wheel will be identical and therefore interchangeable quickly. - The front crankset, the transmission means (chain or belt or shaft), the gear hub integrated in its receiving part of the transmission movement (about half normal right), constitute a fully carded and therefore perfectly sealed externally and externally this which allows a possible lubrication with extremely fluid oil which improves all the mechanical efficiency. The rear wheel and possibly the braking means complete this set to constitute what I call a transmission module.
- le dit module de transmission pourra être monté rigide avec le cadre ou bien être monté oscillant afin d'assurer avec un amortisseur arrière une suspension à la roue arrière. - le poïte bagage avant (support du porte bébé), basculera autour de la base horizontale du guidόtt qui sera située aussi basse que possible.- The said transmission module may be rigidly mounted with the frame or be mounted oscillating to ensure a rear shock with a suspension at the rear wheel. - the front luggage poop (baby carrier support), will swing around the horizontal base of the guidόtt which will be located as low as possible.
- le porte bagage avant permettra de ranger le U d'un antivol de façon à constituer une boucle fermant le dit porte bagage.- The front luggage rack will store the U of a lock so as to constitute a loop closing the said luggage rack.
- le cadre sera constitué dans sa version « city » d'au moins deux tubes principaux (un tube supérieur faisant office de tube de selle dans sa partie arrière, et un tube inférieur (réalisé en au rnbiήs un seul élément) faisant office de garde boue dans sa partie arrière) de diamètre égal ou non, tangent (ou presque) dans la zone de l'axe de direction et dans la partie bàs&e άti dit tube de selle.- the frame will be constituted in its "city" version of at least two main tubes (an upper tube serving as a seat tube in its rear part, and a lower tube (made in a single element rnbiήs) serving as guard mud in its rear part) of equal or non-equal diameter, tangent (or almost) in the area of the steering axis and in the part bàs & e ditti said seat tube.
- le porte bagage arrière sera constituer d'une boucle en épingle à cheveux qui contribuera à la rigidité de la partie arrière du cadre grâce à au moins une traverse solidaire du dit porte bagage et du turiè garde boue- The rear luggage rack will be a loop hairpin that will contribute to the rigidity of the rear part of the frame with at least one crosspiece integral with said luggage rack and turi mudguard
- le tube garde boue aura sa partie cintrée arrière concentrique (ou presque) de l'axe de roue arrière et pourra avoir un profil particulièrement étudié pour optimiser son rôle de garde boue. - la fourche avant sera particulièrement adaptée pour recevoir une roue identique à la roύë arrière, et par conséquent la dite fourche recevra avantageusement un moyeu dynamo monté en porte à faux de façon similaire au dit moyeu arrière à vitesses intégrées.- The mudguard tube will have its curved rear portion concentric (or almost) of the rear wheel axle and may have a profile particularly designed to optimize its role mudguard. the front fork will be particularly adapted to receive a wheel identical to the rear wheel, and therefore said fork will advantageously receive a dynamo hub mounted cantilever similarly to said rear hub with integrated speeds.

En référence à ces dessins, les systèmes sont particulièrement destinés à équiper un vélo (1), préférentiellement selon l'invention la roue avant (2) est identique à la roue arrière (3). Les dites roues sont montées selon l'invention en porte à faux sur des moyeux fusées selon l'invention ou modifié selon l'invention, pour cela la fourche avant (4) selon l'invention et le cadre (9) selon l'invention sont du type monobras c'est-à-dire qu'ils permettent la libre sortie latérale des dites roues (2) et (3). Des moyens de freinage (31), disque arrière par exemple et (41) disque avant par exemple restant solidaire du vélo quand les roues (2) et (3) selon l'invention sont retirées.With reference to these drawings, the systems are particularly intended to equip a bicycle (1), preferably according to the invention the front wheel (2) is identical to the rear wheel (3). Said wheels are mounted according to the invention cantilevered on rocket hubs according to the invention or modified according to the invention, for this the front fork (4) according to the invention and the frame (9) according to the invention are one-arm type that is to say that they allow the free lateral exit of said wheels (2) and (3). Braking means (31), rear disc for example and (41) front disc for example remaining secured to the bicycle when the wheels (2) and (3) according to the invention are removed.
Un guidon (5) coopérant avec la fourche (4) assure la direction. A la base horizontale du guidon (5), directement ou non, un porte bagage (13) selon l'invention bascule d'avant en arrière. En position avant (figure 1) le dit porte bagage (13) reçoit préférentiellement un panier (15a) qui se positionne avantageusement plus ou moins entre les branches verticales du guidon (5). En position arrière (figure 2) le dit porte bagage (13) reçoit préférentiellement un porte bébé (15b) qui se positionne avantageusement plus ou moins entre les branches verticales du guidon (5).A handlebar (5) cooperating with the fork (4) provides steering. At the horizontal base of the handlebar (5), directly or not, a baggage carrier (13) according to the invention rocking back and forth.

Un dispositif av^nt d'éclairage et/ou de signalisation (11) se situe(nt) entre la base du guidon (5) et le pneu (2),An illuminating and / or signaling device (11) is located between the base of the handlebar (5) and the tire (2),
Une selle (6) montée sur une tige de selle (7) coulisse classiquement dans un tube de selle (9c) selon l'invention. Un moyen de serrage (8) traditionnel ou non assure le blocage de la tige de selle à la hauteur de selle (6) souhaitée. Un moyeu arrière à vitesses- intégrées (118) (par exemple : « Shimano Nexus » (marque déposée) SG-3R40) qtt'H soit issue de modèles existants et modifié (principalement par la dépose ou l'usinage des flasques porteuse des têtes de rayons) pour satisfaire à l'invention ou étudié spécifiquement pour répondre à l'invention, est monté en porte à faux grâce à au moins un carter seul (107) ou avec un couvercle (125) du dit carter (107) selon l'invention et qui est relié dans sa partie arrière par des platines (109) au cadre (9) (ou à l'amortisseur). Le dit moyeu à vitesses intégrées (118) constitue donc selon l'invention une fusée pouvant recevoir facilement et rapidement la partie centrale (121) (moyeu) d'une roue arrière (3) monobloc ou non (à rayons classiques ou à bâtons). Par moyeu arrière à vitesses intégrées (118) je sous entend le dispositif complet de changement de vitesses tel que référencé par exemple par la société « Shimano » (marque déposée) pour le modèle « Nexus »(marque déposée) sous le numéro : SG3R40 ; il peut par simplification ne désigner que la partie maîtresse tournante (le corps de moyeu) et servant de moyeu.au rayonnage de la roue arrière (3). Selon un mode particulier de réalisation selon l'invention le dit moyeu à vitesses intégrées (118), le(les) carter(s) (107), le(les) moyen(s) récepteur(s) de transmission (113) associés au moyen de transmission (110) (chaîne, courroie, arbre...) et leur(s) carter(s) (106), le pédalier avant (axe de pédalier, boîtier de pédalier, moyen(s) émetteur(s) de transmission) et leur(s) carter(s) (105), les manivelles (101) et (102), les pédales(103) et (104); la roue (3), le moyen de liaison rapide (117), éventuellement le système de freinage (31), (108), constituent un ensemble harmonieux, cohérent, esthétique et léger mais avant tout rigide et étanche que je nomme « module de transmission » (10). Le dit module de transmission (10) pouvant recevoir tout type de cadre : VTT, VTC, route, femme enfant, vélo couché, triporteur... en solo ou en tandem. Un dispositif arrière d'éclairage et/ou de signalisation (12) se situe(nt) à l'extrémité arrière du tube (9b).A saddle (6) mounted on a seat post (7) slides conventionally in a seat tube (9c) according to the invention. A traditional or non-conventional clamping means (8) ensures the locking of the seat post at the desired saddle height (6). An integrated rear-gear hub (118) (for example: "Shimano Nexus" (registered trade mark) SG-3R40) qtt'H is derived from existing models and modified (mainly by the removal or machining of the head-carrying flanges) of rays) to meet the invention or specifically studied to meet the invention, is mounted cantilevered by at least one housing (107) or with a cover (125) of said housing (107) according to the invention. invention and which is connected in its rear part by plates (109) to the frame (9) (or the damper). Said hub with integrated speeds (118) therefore constitutes according to the invention a rocket that can easily and quickly receive the central portion (121) (hub) of a rear wheel (3) monobloc or not (conventional spokes or sticks) . By rear hub with integrated speeds (118) I mean the complete gearshift device as referenced for example by the company "Shimano" (trademark) for the model "Nexus" (registered trademark) under the number: SG3R40; it can for simplicity designate only the rotating center part (the hub body) and serving as a hub.a rack of the rear wheel (3). According to a particular embodiment of the invention said integrated gear hub (118), the housing (s) (107), the means (s) transmission receiver (s) (113) associated by means of transmission (110) (chain, belt, shaft ...) and their casing (s) (106), the front pedal (pedal axle, bottom bracket, means (s) transmitter (s) transmission) and their crankcase (s) (105), the cranks (101) and (102), the pedals (103) and (104); the wheel (3), the rapid connection means (117), possibly the braking system (31), (108), constitute a harmonious, coherent, aesthetic and light but above all rigid and waterproof, which I call "module of transmission "(10). The said transmission module (10) can receive any type of frame: mountain bike, VTC, road, woman child, recumbent bike, scooter ... solo or tandem. A rear lighting and / or signaling device (12) is located at the rear end of the tube (9b).
Préférentiellement selon l'invention et comme indiqué sur la figure 3 la fourche (4) qu'elle soit constituée d'un ou plusieurs éléments reliant la partie centrale (axe de roue) au platines inférieure (4c) et supérieure (4d) et constituant un monobras latéral, comprend : - une b,aβe formant carter pour recevoir un moyeu dynamo (par exemple de marque « Shunanα » rjanarque déposée), type DH-2R30-E), un axe de direction (4a) tournant sur au moins deux paliers (4b) (roulements par exemple) logés dans la colonne de direction (9a), une platine inférieure (4c) et une platine supérieure (4d) qui sert de support au fixation inférieures (Sb) Φ$ $έÔdon (5). Des demi colliers (5a) permettent le serrage plus ou moins rapide sur position souhaitée du guidon (5). Le porte bagage avant (13) est constitué de deux tubes parallèles, solidaires (soudés par exemple) de deux demi colliers (13a) munies de moyen(s) de butée angulaire assurant la position basculée sur l'avant ou basculée sur l'arrière du dit porte bagage (13). Deux autres demi colliers (13b) coopèrent avec les demi colliers (13a) pour assurer le maintien libre en rotation du dit porte bagage (13). A ses extrémités libres le porte bagage (13) accueil le U (14a) d'un antivol (14) déverrouillé par une clé (14b). Au moins une traverse reliera les deux tubes du porte bagage avant (13). Un panier (15) de type fixation rapide par étaux à ressorts peut se fixer plus ou moins entre les branches verticales du guidon (5) sur le porte bagage (13). Préférentiellement selon l'invention et comme indiqué sur la figure 4 le cadre (9) est constitué : - d'une colonne de direction (9a) aussi courte que possible sur laquelle vient se fixer un tube inférieur (9b) réalisé en un ou plusieurs tubes de profils identiques ou différents et ayant schématiquement la forme d'un V, la partie arrière de ce tube (9b) contourne le pneu arrière d'assez près afin de constituer un garde boue se terminant avec une extrémité droite horizontale ou presque sur laquelle vient se fixer le feu rouge arrière (12) - d'un tube supérieur (9c) ayant schématiquement la forme d'un V, préférentiellement d'un diamètre légèrement plus petit que le tube (9b) le dit tube (9c) tangente le tube (9b) une première fois au niyeau de la colonne de direction (9a) et une deuxième fois dans sa partie basse arrière -d'un support avant (9d) du module de transmission (10) et qui est une sorte de grosse entretoise (filetée ou non) fixée à la fois sur le tube (9b) et le tube (9c) - en cas de cadre (9) rigide (c'est-à-dire dépourvu de suspension arrière) un tube (9e) fait office de hauban entre le tube ($b) et le module de transmission (10), à son extrémité inférieure le dit tube (9e) porte une sorte de grosse entretoise (9f) (filetée ou non) qui sert de fixation aux platines ( 109) du carter (107). Le porte bagage arrière (9L) contribue à la rigidité de la partie arrière du cadre (9), il est réalisé par un tube en épingle à cheveux refermé en V à ses extrémités avant qui viennent se fixer (soudure par exemple) à la partie arrière haute du tube de selle (9c). Une traverse avant (9h) et une traverse arrière (9i) solidarisent le porte bagage (9L) au tube (9b). Des tiges (9j) assurent le maiilage du porte bagage arrière (9L). Un élément esthétique et fonctionnel (9k) solidaire de la colonne de direction (9a) est le support du moyen d'éclairage avant (11).Preferably, according to the invention and as indicated in FIG. 3, the fork (4) consists of one or more elements connecting the central part (wheel axle) to the lower (4c) and upper (4d) plates and constituting a lateral single arm, comprises: - a b, acee forming a housing for receiving a dynamo hub (for example brand "Shunanα" rjanarque filed), type DH-2R30-E), a steering axis (4a) rotating on at least two bearings (4b) (bearings for example) housed in the steering column (9a), a bottom plate (4c) and an upper plate (4d) which serves as support for the lower attachment (Sb) Φ $ $ έÔdon (5). Half collars (5a) allow the more or less rapid clamping on desired position of the handlebar (5). The front luggage rack (13) consists of two parallel tubes, integral (welded for example) with two half-collars (13a) provided with means (s) of angular stop ensuring the tilted position on the front or tilted on the back of said luggage rack (13). Two other half-collars (13b) cooperate with the half-collars (13a) to maintain free rotation of said luggage carrier (13). At its free ends the luggage rack (13) home the U (14a) of a lock (14) unlocked by a key (14b). At least one cross member will connect the two tubes of the front luggage rack (13). A basket (15) of quick fastening type by spring clamps can be fixed more or less between the vertical branches of the handlebar (5) on the luggage rack (13). Preferably, according to the invention and as indicated in FIG. 4, the frame (9) consists of: a steering column (9a) as short as possible on which is fixed a lower tube (9b) made in one or more tubes of identical or different profiles and having schematically the shape of a V, the rear part of this tube (9b) bypasses the rear tire close enough to form a mudguard ending with a horizontal end or almost on which the rear red light (12) is fixed to an upper tube (9c) having schematically in the form of a V, preferably of a diameter slightly smaller than the tube (9b), said tube (9c) tangent to the tube (9b) a first time in the niyeau of the steering column (9a) and a second time in its lower rear part -a front support (9d) of the transmission module (10) and which is a kind of big spacer (threaded or not) attached to both the tube (9b) and the tube (9c) - in case of frame (9) rigid (that is to say without rear suspension) a tube (9e) serves as a stay between the tube ($ b) and the module transmission (10), at its lower end said tube (9e) carries a kind of large spacer (9f) (threaded or not) which serves to fix the plates (109) of the housing (107). The rear luggage rack (9L) contributes to the rigidity of the rear part of the frame (9), it is made by a V-shaped hairpin tube at its front ends which are fixed (welding for example) to the part rear seat tube (9c). A front cross member (9h) and a rear cross member (9i) secure the luggage carrier (9L) to the tube (9b). Stems (9j) provide the rear luggage rack (9L) with a canopy. An aesthetic and functional element (9k) integral with the steering column (9a) is the support of the front lighting means (11).
Préférentiellement selon l'invention et comme indiqué sur les figures 5a, 5b et 5c le module de transmission, (10) quel que soit le moyen de transmission (chaîne, courroie...) et en l'occurrence arbre^ comprend : - un carter et son couvercle, constituant un boîtier de pédalier (105) dans lequel tourne l'axe de pédalier animé par des manivelles (101) et (102) porteuses des pédales (103) et (104) - un carter de transmission (106) qui solidarise de façon hyperstatique le *;a£i^.{105) au carter (107) qui reçoit le moyeu arrière à vitesses intégrées (118) qui entrÉae .la roue arrièrβ (3). La dite roue arrière (3) est retirable et remontable rapidement grâce au moyen de.-tyaj.son rapide (117). Préférentiellement selon l'invention et comme indiqué sur la figure 6 qui en l'occurrence est une configuration module de transmission par courroie crantée, on peut voir dans cette vue en coupe que la courroie crantée (110) de transmission motrice est mise sous tension constante (ou presque) sur son brin mou grâce à un galet avant (111) et un galet arrière (112). De préférence c'est le galet avant (111) qui est actionné par un poussoir à vis ou à ressort pour constituer un tendeur de courroie (110) (ou de chaîne). On voit bien que la couronne émettrice de la transmission est accessible par un couvercle démontable facilement (emboîtement par exemple) concentrique de l'axe de pédalier. De manière plus ou moins similaire, un couvercle éventuel (125) devient le point de fixation droit du moyeu arrière à vitesses intégrées (118) ou plus précisément de son axe principal (114), ce couvercle (125) est fixé au carter (107), il permet entre autre l'accès au pignon récepteur (113) de la transmission.Preferably according to the invention and as indicated in FIGS. 5a, 5b and 5c, the transmission module, (10) regardless of the transmission means (chain, belt, etc.) and in this case tree, comprises: housing and cover therefor, constituting a bottom bracket (105) in which the crank axle is driven by cranks (101) and (102) carrying pedals (103) and (104) - a transmission housing (106) which meshes (105) to the housing (107) which receives the integrated rear speed hub (118) in a hyperstatic manner (118). which enters the rear wheel (3). Said rear wheel (3) is removable and remountable quickly by means of -.-tyaj.son rapid (117). Preferably according to the invention and as indicated in FIG. 6, which in this case is a notched belt transmission module configuration, it can be seen in this sectional view that the toothed belt (110) for driving transmission is put under constant tension. (or almost) on its soft strand thanks to a front roller (111) and a rear roller (112). Preferably it is the front roller (111) which is actuated by a screw or spring plunger to form a belt tensioner (110) (or chain). It is clear that the transmitting crown of the transmission is accessible by a removable cover easily (interlocking for example) concentric to the bottom bracket axis. More or less similarly, a possible cover (125) becomes the right attachment point of the rear hub with integrated speeds (118) or more precisely of its main axis (114), this cover (125) is fixed to the housing (107). ), it allows among other access to the pinion receiver (113) of the transmission.
A l'arrière oîi distingue ce qui est mis encore plus en évidence sur la figure 7 qui est une vue agrandie de la 2one du moyeu arrière de la figure 6 et qui est la principale caractéristique de Pinverition c'est à dire un moyeu à vitesses intégrées (118) tournant sur un axe (114), par ses extrémités le dit axe (114), traditionnellement fixe la roue arrière à la fourche (embases et haubans éventuels) arrière du cadre (ou au bras oscillant en cas de suspension) et qui est bien sur immobilisé en rotation par au moins une de ses extrémités, le mécanisme de changement de vitesse (non représenté sur cette vue) sortant coté droit ; et bien cette axe (114). est selon l'invention toujours immobilisé en rotation par une plaque antirotation (122), et en translation par un écrou (123) prenant appui sur le carter (107) ou le couvercle éventuel (125), mais uniquement que d'un seul coté, par l'extrémité droite en l'occurrence. En effet la dij:e extrémité droite de l'axe (114) est solidaire du carter (107) ou du couvercle éventuel (125) et constitue le premier point d'appui de l'axe de roue arrière situé dans un plan vertical longitudinal et plutôt extérieur du véhicule. Le second point d'appui de l'axe de roue arrière est par contre très caractéristique de l'invention dans le sens ou il est situé dans un autre plan vertical longitudinal, mais plutôt central du véhicule et réalisé de façon indirecte par l'extérieur du corps du moyeu à vitesses intégrées (118) tournant dans un palier extérieur (115) (roulement à billes par exemple) d'assez grand diamètre donc. Le dit jsalier extérieur (115) pourra recevoir directement ou par l'intermédiaire d'une platine (120) porteuse du disque de frein (31), l'extérieur du dit moyeu à vitesses intégrées (HS) (représenté vide car seul l'extérieur du dit moyeu à vitesses intégrées (118) est nécessaire à la compréhension de l'invention). Le dit palier (115) est logé â P intérieur de l'autre extrémité (confondu ou presque avec le plan central vertical et longitudinal du cycle (I)) du carter (107). Pour satisfaire au maintien du porte disque (120) sur le moyeu à vitesses intégrées (118), une vis spéciale (124) cale et serre le dit porte disque (120) sur le moyeu à vitesses intégrées (118). Selon l'invention on constate donc que l'extrémité gauche (normalement) de l'axe (114) est laissée parfaitement libre, sans aucun lien avec le cadre. La roue arrière (3) particulièrement étudié pour coopérer avec le moyeu à vitesses intégrées (118) est constitué selon l'invention : - d'une jante et de rayons ou battons (monobloc ou assemblés) solidaire d'un moyeu (121) monobloc ou rapporté. L'extrémité gauche du dit moyeu (121) porte un palier (roulement) (116) (préférentiellement munie d'une bague (129) assurant l'interface entre le roulement (116) et l'axe (114) ou son écrou (119) et le moyen de liaison (117).) qui vient créer un premier point de centrage libre en rotation sur l'extrémité fixe gauche de l'axe (114). Le deuxième point de centrage est réalisé par l'ajustage <Lé l'alésage (lisse ou cannelé) du moyeu de roue (3, 121) qui vient coiffer (en correspondance de cannelures éventuelles) l'extrémité (lisse ou cannelée) extérieure du porte disque (120). Au moins un moyen rapide (par exemple et de façon préférentielle les cannelures déjà existantes sur certain moyeu à vitesses intégrées (118), ou bien au moins une clavette..) de liaison en rotation (aussi bien pour la force motrice que pour le freinage) sont réaliser entre le moyeu à vitesses intégrées (118) et le moyeu de roue (121).At the rear, which distinguishes what is highlighted even more in FIG. 7, which is an enlarged view of the rear hub 2one of FIG. 6 and which is the main characteristic of Pinverition, that is to say a gear hub. integrated (118) rotating on an axis (114), at its ends said axis (114), traditionally fixed rear wheel fork (possible bases and shrouds) back of the frame (or the swingarm in case of suspension) and which is of course immobilized in rotation by at least one of its ends, the gearshift mechanism (not shown in this view) coming out on the right side; and well this axis (114). according to the invention is always immobilized in rotation by an antirotation plate (122), and in translation by a nut (123) bearing on the casing (107) or the possible cover (125), but only on one side , by the right end in this case. Indeed the dij: e right end of the axis (114) is integral with the casing (107) or the possible cover (125) and is the first point of support of the rear wheel axle located in a longitudinal vertical plane and rather outside the vehicle. The second bearing point of the rear wheel axle, on the other hand, is very characteristic of the invention in the sense that it is located in another longitudinal vertical plane, but rather central to the vehicle and indirectly made by the outside. the body of the hub with integrated speeds (118) rotating in an outer bearing (115) (ball bearing for example) of large enough diameter. The said jsalier outside (115) can receive directly or through a plate (120) carrier of the brake disc (31), the outside said integrated gear hub (HS) (shown empty because only the outside of said integrated gear hub (118) is necessary for the understanding of the invention). Said bearing (115) is housed inside the other end (almost coincident with the vertical and longitudinal central plane of the cycle (I)) of the housing (107). To satisfy the retention of the disk carrier (120) on the integrated gear hub (118), a special screw (124) wedges and clamps said disk carrier (120) to the integral gear hub (118). According to the invention we therefore see that the left end (normally) of the axis (114) is left perfectly free, with no connection with the frame. The rear wheel (3) particularly designed to cooperate with the gear hub (118) is constituted according to the invention: - a rim and spokes or battens (monoblock or assembled) integral with a hub (121) monobloc or reported. The left end of said hub (121) carries a bearing (bearing) (116) (preferably provided with a ring (129) providing the interface between the bearing (116) and the shaft (114) or its nut ( 119) and the connecting means (117).) Which creates a first centering point free to rotate on the left fixed end of the axis (114). The second centering point is made by adjusting the boring (smooth or fluted) of the wheel hub (3, 121) which caps (in correspondence of any splines) the outer (smooth or fluted) end of the disc carrier (120). At least one quick means (for example and preferably the grooves already existing on some hub with integrated speeds (118), or at least one key ..) of connection in rotation (as well for the driving force as for the braking ) are provided between the integrated gear hub (118) and the wheel hub (121).
Les vis (127) qui fixent le disque (31) sur le porte disque (120) pourront selon l'invention être suffisamment longues pour que la partie dépassant le porte disque (120) soit préférentiellement décolletée pour être lisse et constituer des pions de liaison entre la partie basse des bâtons de la roue (3) et le disque (31), reprenant ainsi au mieux le couple engendré au freinage entre le disque (31) et la roue (3).The screws (127) which fix the disk (31) on the disk carrier (120) may according to the invention be long enough so that the portion protruding from the disk carrier (120) is preferably décolletée to be smooth and constitute connecting pins between the lower part of the sticks of the wheel (3) and the disk (31), thereby taking the best possible torque generated during braking between the disc (31) and the wheel (3).
Selon l'invention un moyen de liaison (117) rapide, solidaire de la roue (3) par l'intermédiaire du palier (116), assure le maintien de la roue (3) sur l'axe (114) directement ou non. De manière indirecte ; est vissé sur l'extrémité gauche (raccourcie ou non) de l'axe (114) un écrou {l 19) spécialement munie d'une gorge extérieure permettant rapidement un clipsage automatique (par simple poussée axiale sur la roue (3)) et un déclipsage (par simple pression entre le pouce et l'index) et chanfreiné pour facilité l'introduction et le retrait du moyen de liaasβn (117) et donc de la roue (3). Préférentiellement selon l'invention et comme indiqué sur la figure 8 on peut retrouver les éléments décrits précédemment, mais ici la vue de détail de la figure 5 c montre donciïrie configuration de module de transmission par arbre. Apparaît sur cette vue le mécanisme de changement de vitesse (128) commandé depuis le guidon (5) par un câble (126). Un couvercle (125) protège de façon étanche le mécanisme de changement de vitesse (128).According to the invention a rapid connection means (117) secured to the wheel (3) via the bearing (116) ensures the maintenance of the wheel (3) on the axis (114) directly or not. Indirectly; is screwed on the left end (shortened or not) of the shaft (114) a nut (l 19) specially provided with an outer groove for rapid automatic clipping (by simply thrusting axially on the wheel (3)) and unclipping (by simply pressing between the thumb and forefinger) and chamfered for ease of introduction and withdrawal liaasβn means (117) and thus the wheel (3). Preferably, according to the invention and as indicated in FIG. 8, the elements described above can be found, but here the detailed view of FIG. 5c thus shows the configuration of the transmission module per shaft. Appears in this view the gearshift mechanism (128) controlled from the handlebar (5) by a cable (126). A cover (125) sealingly protects the gearshift mechanism (128).
Préférentiellement selon l'invention et comme indiqué sur la figure 9 et sur la vue de détail de la figure 9 qu'est la figure 10, on voit un module de transmission correspondant aux figures 5a, 5b et 5c mais ou la roue arrière (3) est retiré latéralement suivant l'axe de sortie et de rentrée x-y. Ces vues montrent clairement le montage en porte à faux du moyeu à vitesses intégrées (118) et comment se séparent les différents éléments.Preferably according to the invention and as indicated in FIG. 9 and in the detail view of FIG. 9 that is FIG. 10, a transmission module corresponding to FIGS. 5a, 5b and 5c is seen, but the rear wheel (FIG. ) is withdrawn laterally along the exit and exit axis xy. These views clearly show the cantilevered mounting of the integrated gear hub (118) and how the various elements separate.
Selon une variante particulièrement intéressante selon l'invention, le carter (107), porte des platinés (109) qui en plus de servir de moyen de fixation au cadre (9) intègre directement rétrier de frein (108) qui dans les figures 9 et 10 notamment est monté sur une platine qtύ est donc facultative.According to a particularly advantageous variant according to the invention, the casing (107) bears platinums (109) which, in addition to serving as a means of attachment to the frame (9), directly integrates the brake retractor (108) which in FIGS. In particular, it is mounted on a plate which is therefore optional.
