Abstract

The invention relates to the incorporation of a disc brake calliper in available locations on a bicycle structure, namely either the front wheel fork or the stays or swing arms of the rear wheel frame. In the hydraulically controlled mode, the detachable calliper (6) and the fork blade (or fork frame) (14) are rigidly interconnected via screws 01 and 02 (12, 13). The hydraulic fluid flows from the hose (11) (which is in turn connected to the brake lever) to the fork blade (or fork frame) via screw 03 (10) then from the fork blade (or fork frame) (14) to the detachable calliper (6) via channel 01 (8). The pressurised fluid actuates the pistons (15), which in turn actuate the brake pads (7). When braking, the pads are urged against the disc. Said disc brake is characterised by improved rigidity, a lighter weight and an enhanced design.

Description

Frein à disque pour cycles VTT ou route, à étrier intégré dans la structure du cycle, fourche avant ou cadre de roue arrière. Disc brake for MTB or road cycles, with caliper integrated in the cycle structure, front fork or rear wheel frame.
Secteur technique de l'invention :Technical sector of the invention:
La présente invention concerne le secteur technique des cycles en général, et notamment des cycles dits « VIT » pour le « tout-terrain » ou dits « de route » pour la course ou les randonnées, et tout véhicule comportant des systèmes de freinage identiques ou analogues à ceux des « cycles », y compris vélomoteurs, « scooters », bicyclettes, patinettes, motos, fauteuils roulants et analogues que saura déterminer l'homme de métier.The present invention relates to the technical sector of cycles in general, and in particular so-called “VIT” cycles for “all-terrain” or so-called “road” cycles for running or hiking, and any vehicle comprising identical braking systems or analogous to those of "cycles", including mopeds, "scooters", bicycles, scooters, motorcycles, wheelchairs and the like that will be determined by the skilled person.
L'ensemble sera désigné par simplicité par « cycles » ou « cycle », dans toute la présente demande, y compris les revendications.The assembly will be designated for simplicity by "cycles" or "cycle" throughout the present application, including the claims.
Art antérieur :Prior art:
On connaît naturellement des systèmes de freinage pour cycles, notamment dans les deux secteurs suivants.Braking systems for cycles are naturally known, in particular in the following two sectors.
VTT (figure 1)ATV (Figure 1)
On connaît des systèmes de freinage à disque, avec étrier 5 de frein séparé de la fourche 1 pour la roue avant, ou du cadre pour la roue arrière.Disc brake systems are known, with brake caliper 5 separate from the fork 1 for the front wheel, or from the frame for the rear wheel.
L'étrier constitue une pièce à part entière, et est généralement solidaire des bras de fourche ou des haubans du cadre par l'intermédiaire de vis de fixation 4 et de supports de fixation 2 et 3 coopérant entre eux. Inconvénients de cette solutionThe stirrup constitutes a part in its own right, and is generally secured to the fork arms or the seat stays of the frame by means of fixing screws 4 and fixing supports 2 and 3 cooperating with each other. Disadvantages of this solution
- Le poids est trop élevé.- The weight is too high.
- La rigidité est trop faible.- The rigidity is too low.
- « Design » ou conception compliqué en raison de l'ajout (évolution historique du VTT) de plusieurs fonctions.- “Design” or complicated design due to the addition (historical evolution of mountain biking) of several functions.
- Coût de la fonction frein ajouté et non intégré- Cost of the brake function added and not integrated
RouteRoad
Dans le cas précis de la route, le disque est absent car le rapport poids/efficacité de la fonction freinage est nettement favorable aux freins classiques (patins qui serrent la jante).In the specific case of the road, the disc is absent because the weight / efficiency ratio of the braking function is clearly favorable to conventional brakes (pads which tighten the rim).
Inconvénients de cette solutionDisadvantages of this solution
- Performance non optimum surtout sous la pluie- Non-optimum performance especially in the rain
- Design basique et compliqué (multitude de pièces liée à la conception de la fonction train à patin)- Basic and complicated design (multitude of parts linked to the design of the skate train function)
On notera que le poids de la fonction disque dite « classique » c'est-à-dire de l'art antérieur, est trop élevé pour que cette fonction « frein à disque » puisse être mise en oeuvre sur les vélos de course.It will be noted that the weight of the so-called “conventional” disc function, that is to say of the prior art, is too high for this “disc brake” function to be able to be implemented on racing bikes.
Le poids est donc un facteur important.Weight is therefore an important factor.
Problème technique posé :Technical problem:
Il existe donc un besoin important et reconnu pour un système de freinage performant à disque, pour cycles, aussi bien pour VTT que pour route, et analogues décrits ci-dessus, combinant légèreté et rigidité, tout en conservant ou augmentant l'efficacité de freinage. On voit immédiatement que ces objectifs sont antagonistes.There is therefore a significant and recognized need for a high-performance disc brake system for cycles, both for mountain bikes and for roads, and analogs described above, combining lightness and rigidity, while maintaining or increasing the braking efficiency. We can immediately see that these objectives are antagonistic.
L'invention concerne des cycle, du type comportant une « structure » portant la selle, le pédalier et autres organes, et au moins deux roues.The invention relates to cycles, of the type comprising a "structure" carrying the saddle, the crankset and other members, and at least two wheels.
Résumé de l'invention :Summary of the invention:
Le concept général sur lequel repose l'invention consiste à intégrer l'étrier de frein à disque dans la structure du cycle, en des emplacements disponibles, c'est-à-dire soit le bras de fourche de la roue avant, soit les haubans ou bras oscillants de cadre de la roue arrière. Cette intégration a posé un problème technique supplémentaire, car chercher à intégrer un étrier de frein dans des volumes d'encombrement bien définis par les fabricants de cycles et très limités ne pouvait que générer des contraintes sévères. Ces contraintes sont peut être la raison pour laquelle, à ce jour, on n'a pas recherché de solution dans ce » sens.The general concept on which the invention is based consists in integrating the disc brake caliper into the structure of the cycle, in available locations, that is to say either the fork arm of the front wheel, or the seat stays. or rear wheel frame swing arms. This integration posed an additional technical problem, because seeking to integrate a brake caliper in overall dimensions well defined by the manufacturers of cycles and very limited could only generate severe constraints. These constraints are perhaps the reason why, to date, no solution has been sought in this direction.
Notamment, l'homme de métier savait qu'il allait inévitablement rencontrer de nombreuses difficultés, dont les suivantes :In particular, the skilled person knew that he would inevitably encounter many difficulties, including the following:
Difficultés majeures :Major difficulties:
- réglage du centrage du disque par rapport aux plaquettes- adjustment of the centering of the disc in relation to the pads
- développement du système de freinage proprement dit- development of the actual braking system
- résistance mécanique L'un des mérites de l'invention est d'avoir cherché une solution dans cette voie très élégante techniquement mais corollairement très difficile, et d 'avoir trouvé une solution technique applicable dans la pratique.- mechanical resistance One of the merits of the invention is to have sought a solution in this technically very elegant but corollarily very difficult way, and to have found a technical solution applicable in practice.
L'invention concerne donc des cycles caractérisés en ce que :The invention therefore relates to cycles characterized in that:
ils comportent un système de freinage à disque au moins sur une de leurs roues,they have a disc braking system on at least one of their wheels,
et en ce que l'étrier de ce système de freinage à disque est intégré dans la structure du cycle.and in that the caliper of this disc brake system is integrated into the cycle structure.
L'homme de métier aura compris que, dans toute la présente demande, y compris les revendications, « structure » de cycle désigne les éléments tubulaires qui forment la structure générale du cycle, et sur lesquels sont fixés les roues, le pédalier , la selle, etc..A person skilled in the art will have understood that, throughout the present application, including the claims, cycle “structure” designates the tubular elements which form the general structure of the cycle, and on which the wheels, the crankset, the saddle are fixed. , etc.
Points originaux de la solutionOriginal points of the solution
- Globaliser les fonctions fourche (direction, suspensions...) et freinage et avoir une offre complète pour les constructeurs de cycles.- Globalize the fork (steering, suspension, etc.) and braking functions and have a complete offer for cycle builders.
- Gain important de poids et en coût , à fonction de freinage équivalente.- Significant gain in weight and cost, with equivalent braking function.
- Augmentation de la rigidité.- Increased rigidity.
- Augmentation des performances à poids égal (pour la route)- Performance increase at equal weight (for the road)
Selon un mode de réalisation particulier, le cycle selon l'invention comporte in tel système de freinage sur la roue avant et la roue arrière.According to a particular embodiment, the cycle according to the invention comprises in such a braking system on the front wheel and the rear wheel.
Comme on le verra, on parvient à une solution techniquement efficace, avec de plus un « design » élégant car donnant au cycle une silhouette très fluide, qui est de plus en plus recherchée, en employant de préférence : un disque flottant (c'est-à-dire, comme le sait l'homme de métier, une disposition qui permet un déplacement axial du disque (pour optimiser l'alignement du disque par rapport aux plaquettes))As we will see, we arrive at a technically effective solution, with an elegant "design" because giving the cycle a very fluid silhouette, which is more and more sought after, preferably using: a floating disc (that is to say, as the person skilled in the art knows, an arrangement which allows axial displacement of the disc (to optimize the alignment of the disc relative to the pads))
- des pièces standard telles que vis, pistons et plaquettes (c'est-à-dire issues de disques classiques).- standard parts such as screws, pistons and pads (that is to say from conventional discs).
Cette possibilité n'était pas non plus évidente, car les pièces standard ne sont pas conçues pour être intégrées dans des volumes réduits. L'homme de métier comprendra que cette possibilité, offerte par l'invention, d'employer des pièces standard contribue à la réduction du coût, et ne crée pas les difficultés industrielles qu'aurait créé le besoin de nouvelles pièces.This possibility was also not obvious, because standard parts are not designed to be integrated in reduced volumes. Those skilled in the art will understand that this possibility, offered by the invention, of using standard parts contributes to reducing the cost, and does not create the industrial difficulties that the need for new parts would have created.
Description détaillée de l'invention :Detailed description of the invention:
L'invention concerne donc selon un premier mode de réalisation un cycle caractérisé en ce que :The invention therefore relates, according to a first embodiment, to a cycle characterized in that:
- il comporte un système de freinage à disque au moins sur une de ses roues,- it has a disc braking system at least on one of its wheels,
et en ce que l'étrier de ce système de freinage à disque est intégré dans le bras de la fourche de la roue avant du cycle.and in that the caliper of this disc braking system is integrated into the fork arm of the front wheel of the cycle.
On se référera à la figure 2, à la figure 4 et à la figure 5.Reference is made to FIG. 2, to FIG. 4 and to FIG. 5.
Sur les figures 4 et 5, on verra que l'invention peut s'appliquer, aussi bien en mode à commande hydraulique qu'à un mode à commande par câble, sur le bras de fourche avant ou le cadre arrière (14).In FIGS. 4 and 5, it will be seen that the invention can be applied, both in hydraulic control mode and in cable control mode, to the front fork arm or the rear frame (14).
Selon un mode de réalisation particulier, le système de freinage est à commande hydraulique (figure 2, figure 3, figure 4).According to a particular embodiment, the braking system is hydraulically controlled (Figure 2, Figure 3, Figure 4).
La figure 2 est une vue en perspective 3D selon deux angles différents, figure 2A et figure 2B, où l'on remarque que selon l'invention l'étrier démontable 6 est intégré dans le bras de fourche 1 (ou cadre) qui comprend l'étrier non démontable de la roue avant, ce qui procure les avantages techniques recherchés ainsi qu'un « design » plus fluide.Figure 2 is a 3D perspective view from two different angles, Figure 2A and Figure 2B, where it is noted that according to the invention the stirrup removable 6 is integrated in the fork arm 1 (or frame) which includes the non-removable caliper of the front wheel, which provides the desired technical advantages as well as a more fluid "design".
La figure 3 est, comme la figure 2, une vue en perspective 3D de la structure du cycle et notamment des haubans 20 du cadre de roue arrière, montrant également l'intégration de l'étrier 6 selon l'invention et l'aspect qui en découle.FIG. 3 is, like FIG. 2, a 3D perspective view of the structure of the cycle and in particular of the shrouds 20 of the rear wheel frame, also showing the integration of the caliper 6 according to the invention and the appearance which resulting.
Sur la figure 4, l'étrier démontable 6 et le bras de fourche (ou cadre) 14 sont solidaires grâce aux vis 01 et 02 (1 et 13) . Le liquide hydraulique communique depuis la durite 11 (elle-même reliée au levier de frein) avec le bras de fourche (ou cadre) par l'intermédiaire de la vis 03 (10) puis communique entre le bras de fourche (ou cadre) 14 et l'étrier démontable 6 par le canal 01 (8). Le liquide sous pression agit sur les pistons 15 qui agissent eux-mêmes sur les plaquettes 7. Le freinage est ainsi obtenu par le serrage des plaquettes sur le disque.In FIG. 4, the removable stirrup 6 and the fork arm (or frame) 14 are secured by means of the screws 01 and 02 (1 and 13). The hydraulic fluid communicates from the hose 11 (itself connected to the brake lever) with the fork arm (or frame) via the screw 03 (10) then communicates between the fork arm (or frame) 14 and the removable stirrup 6 by the channel 01 (8). The pressurized liquid acts on the pistons 15 which themselves act on the pads 7. Braking is thus obtained by tightening the pads on the disc.
(le disque n'est pas représenté, il est solidaire de la roue)(the disc is not shown, it is integral with the wheel)
Selon un autre mode de réalisation particulier, le système de freinage est à commande par câble (figure 5).According to another particular embodiment, the braking system is controlled by cable (FIG. 5).
L'étrier démontable 6 et le bras de fourche (ou cadre) 14 sont solidaires grâce aux vis 01 et 02 (12, 13). Le câble fait tourner le levier 18 au travers de son passage 16. Le levier 18, par sa rotation et la forme particulière de la came 17, transmet un mouvement de translation axiale de la came qui déplace ainsi la plaquette 1 (7) . La plaquette 2 (7 ) est immobile. La plaquette 1 (7 ) pousse le disque (non représenté) qui se déforme et vient en contact avec la plaquette 2 (7' ). Le freinage est ainsi obtenu par le serrage des plaquettes sur le disque.The removable stirrup 6 and the fork arm (or frame) 14 are integral with the screws 01 and 02 (12, 13). The cable rotates the lever 18 through its passage 16. The lever 18, by its rotation and the particular shape of the cam 17, transmits an axial translational movement of the cam which thus displaces the plate 1 (7). The plate 2 (7) is stationary. The plate 1 (7) pushes the disc (not shown) which deforms and comes into contact with the plate 2 (7 '). Braking is thus obtained by tightening the pads on the disc.
La figure 6 représente une vue en coupe d'un étrier intégré selon l'invention, à commande hydraulique. Les références ont les mêmes significations que sur la figure 4, le disque 20 étant de plus représenté. La figure 7 représente une vue en coupe d'un étrier intégré selon l'invention, à commande à câble. Les références ont les mêmes significations que sur la figure 5, le disque 20 étant de plus représenté.FIG. 6 represents a sectional view of an integrated stirrup according to the invention, with hydraulic control. The references have the same meanings as in FIG. 4, the disc 20 also being shown. FIG. 7 represents a sectional view of an integrated stirrup according to the invention, with cable control. The references have the same meanings as in FIG. 5, the disc 20 also being shown.
Les figures 6 et 7 montrent bien l'intégration de l'étrier de frein à disque dans la structure.Figures 6 and 7 clearly show the integration of the disc brake caliper in the structure.
