Description

DISPOSITIF DE COMMANDE DE DIRECTION POUR MOTOCYCLETTE OU SIMILAIRE  DIRECTION CONTROL DEVICE FOR MOTORCYCLE OR SIMILAR
Domaine technique  Technical area
La présente invention concerne un dispositif de commande de direction pour une motocyclette ou similaire comportant un châssis pourvu d'un élément de maintien d'une fourche de direction à laquelle est attaché un guidon, ledit guidon étant couplé à un ensemble tournant porté par ladite fourche de direction et comportant des organes de suspension-amortisseurs. The present invention relates to a steering control device for a motorcycle or the like comprising a frame provided with a holding element of a steering fork to which is attached a handlebar, said handlebar being coupled to a rotating assembly carried by said fork steering and comprising suspension-shock absorbers.
Technique antérieure Prior art
Les motocyclettes à vocation routière sont des véhicules à deux roues, dont une roue avant est directrice et une roue arrière est motrice. On connaît malheureusement très bien les risques inhérents à la circulation sur route avec ces véhicules, dans les conditions routières habituelles, sur des voies encombrées, des chaussées glissantes etc. La moindre perte d'adhérence peut entraîner la chute du pilote et provoquer un accident grave, voire mortel.  Road motorcycles are two-wheeled vehicles, one of which is a steering wheel and a rear wheel is driving. Unfortunately, we know very well the risks inherent in road traffic with these vehicles, under the usual road conditions, on congested roads, slippery roads, etc. Any loss of traction can cause the driver to fall and cause a serious or even fatal accident.
En outre, la possibilité de transport de produits sur une motocyclette, comme une mallette de documents ou des biens de consommation, est extrêmement réduite. Certaines motocyclettes peuvent être équipées de sacoches latérales fixées au niveau de la roue arrière. Néanmoins la capacité de ces sacoches est limitée en raison de leur encombrement réduit. Pour pallier le problème de la stabilité des véhicules à deux roues, une initiative, qui a consisté à lancer des scooters à trois roues, a connu un certain succès commercial. Elle concerne cependant des scooters et non des motocyclettes, ce qui limite la demande à un public relativement restreint, sachant que la plupart des motocyclistes ne souhaite pas se convertir en scootéristes. Les scooters à trois roues sont des véhicules de conception nouvelle par rapport aux scooters à deux roues et tous les composants des premiers sont distincts des composants des seconds et ne peuvent en aucun cas être interchangés. La commande de direction, le freinage, la suspension et l'amortissement sont adaptés aux véhicules respectifs. In addition, the possibility of transporting products on a motorcycle, such as a briefcase of documents or consumer goods, is extremely small. Some motorcycles may be equipped with side bags attached to the rear wheel. Nevertheless the capacity of these bags is limited because of their reduced size. To overcome the problem of the stability of two-wheeled vehicles, an initiative to launch three-wheeled scooters has had some commercial success. However, it concerns scooters and not motorcycles, which limits the demand to a relatively small audience, knowing that most motorcyclists do not want to become scooters. Three-wheeled scooters are new-design vehicles compared to two-wheeled scooters, and all the components of the two-wheeled scooters are distinct from the components of the latter and can not be interchanged in any case. The order of steering, braking, suspension and damping are adapted to the respective vehicles.
Outre l'avantage de la stabilité du véhicule, les scooters à trois roues disposent d'un espace de rangement supérieur à celui des motocyclettes, ce qui leur donne un avantage pour des déplacements en tenue de ville. D'une manière générale, le motard revêt une combinaison de motard, qui lui assure la meilleure protection possible en cas de chute et il ne dispose quasiment d'aucun espace de rangement pour emporter en plus avec lui des vêtements dits "de ville". Le scootériste peut envisager de circuler avec des vêtements dits "de ville" et dispose en outre d'un espace pour ranger des vêtements de rechange. In addition to the stability of the vehicle, three-wheeled scooters have more storage space than motorcycles, which gives them an advantage when traveling in street clothes. In general, the biker wears a biker's suit, which gives him the best possible protection in the event of a fall and he has almost no storage space to bring with him so-called "city clothes". The scooter operator may consider traveling with so-called "city clothes" and also has space to store extra clothes.
De ce fait, on crée quasi automatiquement deux catégories de conducteurs de véhicules à deux roues sans pouvoir faire bénéficier aux uns des avantages des autres. As a result, two categories of two-wheeled vehicle drivers are almost automatically created without being able to benefit from the advantages of others.
Exposé de l'invention Presentation of the invention
La présente invention se propose de pallier ces inconvénients susmentionnés et de permettre aux motocyclistes de bénéficier de manière simple et à peu de frais des avantages des scooters à trois roues en matière de stabilité et de sécurité et en matière d'espace disponible.  The present invention proposes to overcome these disadvantages mentioned above and to allow motorcyclists to benefit in a simple and inexpensive way the advantages of three-wheeled scooters in terms of stability and safety and in terms of available space.

Meilleures manières de réaliser l'invention Best ways to achieve the invention
Le dispositif de commande de direction 10 pour motocyclette ou similaire, tel qu'illustré par les figures 1 à 3 est monté sur un châssis 11 comportant un guidon 12, et comprend une fourche de direction 13 à laquelle est attaché ledit guidon 12, un ensemble tournant 14 porté par ladite fourche de direction 13, et deux organes 15 de suspension-amortisseurs montés sur ladite fourche de direction 13 pour contrôler les déplacements verticaux dudit ensemble tournant 14. Dans l'exemple représenté, ledit ensemble tournant 14 comporte deux roues indépendantes 14a et 14b montées librement, respectivement sur deux axes fixes 16 portés chacun par un triangle de suspension 17. Les deux triangles de suspension 17 sont constitués chacun d'un bras de suspension 18, articulé sur un élément 19 dudit châssis 11 , et d'un des deux organes de suspension-amortisseurs 15. Ces organes de suspension-amortisseurs 15 sont fixés à un élément de bascule 20 articulé en son milieu à la fourche de direction 13 grâce à un axe de pivotement central 21. Cet assemblage permet au véhicule de s'incliner d'un côté ou de l'autre tout en permettant aux deux roues indépendantes 14a et 14b de se maintenir en appui sur le sol pour améliorer la tenue de route du véhicule par rapport à un véhicule à deux roues classique et pour réduire de manière importante le risque de dérapage de la partie frontale de ce véhicule. Ces inclinaisons sont illustrées par la figure 3 et leur contrôle est précisé ci-après. The steering control device 10 for a motorcycle or the like, as illustrated by FIGS. 1 to 3, is mounted on a frame 11 comprising a handlebar 12, and comprises a steering fork 13 to which said handlebar 12 is attached, a rotating assembly 14 carried by said steering fork 13, and two suspension-shock absorber members mounted on said steering fork 13 for controlling the vertical displacements of said rotating assembly 14. In the example shown, said rotating assembly 14 comprises two wheels independent 14a and 14b mounted freely, respectively on two fixed axes 16 each carried by a suspension triangle 17. The two suspension triangles 17 each consist of a suspension arm 18 articulated on an element 19 of said frame 11, and one of the two suspension-shock absorber members 15. These suspension-shock absorber members 15 are fixed to a rocker element 20 hinged at its middle to the steering fork 13 by means of a central pivoting shaft 21. This assembly allows the vehicle to tilt on one side or the other while allowing the two independent wheels 14a and 14b to rest on the ground to improve the has held the vehicle in relation to a conventional two-wheeled vehicle and to significantly reduce the risk of skidding of the front of this vehicle. These inclinations are illustrated in FIG. 3 and their control is specified below.
La figure 2 représente la motocyclette, vue de l'avant, dans une position droite, c'est-à-dire lorsque son axe est sensiblement vertical ou perpendiculaire à la route. La figure 3 représente cette même motocyclette lorsque le pilote a tourné le guidon 12 à droite, dans le sens de la flèche A. Dans ce cas, la motocyclette penche du côté vers lequel elle tourne et les deux roues directrices 14a et 14b s'inclinent par rapport à leur surface d'appui tout en restant parallèles à elles- mêmes. Cette inclinaison est obtenue grâce à l'élément de bascule 20 qui pivote autour de son axe de pivotement central 21, proportionnellement à l'angle de rotation du guidon 12. Quelle que soit l'inclinaison de la motocyclette, elle disposera de trois points d'appui définis par la bande de roulement des deux roues avant 14a et 14b et de celle de la roue arrière (non représentée). La stabilité de cette motocyclette est considérablement augmentée par rapport à une motocyclette de base qui aura été transformée par le remplacement de son dispositif de commande de direction initial par le dispositif de commande de direction selon l'invention, tel que décrit. Une motocyclette traditionnelle nécessite l'appui sur un pied lorsqu'elle est à l'arrêt. La motocyclette transformée par le montage du dispositif de commande de direction selon l'invention peut être pourvue de moyens de freinage et de blocage en position qui ont pour fonction, notamment d'assurer une stabilité en position verticale ou une stabilité en position inclinée qui remplace le pied classique ou tout autre dispositif de tenue mécanique du véhicule à l'arrêt. Dans l'exemple représenté par les figures 2 et 3, ces moyens de freinage se présentent sous la forme d'un levier de freinage 22 qui est couplé, au moyen d'un câble 23, à deux tambours de freinage 24. Ce système permet de bloquer les roues 14a et 14b dans leur position verticale ou inclinée et d'assurer le maintien dans cette position lorsque le véhicule est à l'arrêt. Figure 2 shows the motorcycle, seen from the front, in an upright position, that is to say when its axis is substantially vertical or perpendicular to the road. FIG. 3 represents this same motorcycle when the pilot has turned the handlebar 12 to the right, in the direction of the arrow A. In this case, the motorcycle leans on the side towards which it turns and the two steering wheels 14a and 14b bow relative to their bearing surface while remaining parallel to themselves. This inclination is obtained thanks to the rocking element 20 which pivots about its central pivot axis 21, proportionally to the angle of rotation of the handlebar 12. Whatever the inclination of the motorcycle, it will have three points of rotation. support defined by the tread of the two front wheels 14a and 14b and that of the rear wheel (not shown). The stability of this motorcycle is considerably increased over a basic motorcycle that has been transformed by replacing its initial steering control device with the steering control device according to the invention as described. A traditional motorcycle requires support on one foot when it is stationary. The motorcycle transformed by the mounting of the steering control device according to the invention can be provided with braking and locking means in position which have the function, in particular to ensure stability in vertical position or stability in an inclined position which replaces the conventional foot or any other mechanical holding device of the vehicle at a standstill. In the example shown in Figures 2 and 3, these braking means are in the form of a brake lever 22 which is coupled, by means of a cable 23, to two braking drums 24. This system allows to lock the wheels 14a and 14b in their vertical or inclined position and to maintain in this position when the vehicle is stopped.
On notera que le bras de suspension 18 est articulé, d'une part, sur l'élément de châssis 19 et, d'autre part, sur un moyeu de roue 25, en un point 26 décalé par rapport à l'axe du moyeu. La base de chacun des organes de suspension- amortisseurs 15 est également montée sur le moyeu de roue 25 en un point 27 qui peut également être décalé par rapport à l'axe du moyeu de la roue 25. Ce mode d'assemblage n'est pas unique et les composants du triangle de suspension 17 pourraient être disposés différemment ou montés différemment par rapport à l'axe du moyeu de roue 25. It will be noted that the suspension arm 18 is articulated, on the one hand, on the frame member 19 and, on the other hand, on a wheel hub 25, at a point 26 offset from the axis of the hub. . The base of each of the suspension-damping members 15 is also mounted on the wheel hub 25 at a point 27 which can also be offset relative to the axis of the hub of the wheel 25. This method of assembly is not unique and the components of the wishbone 17 could be arranged differently or mounted differently relative to the axis of the wheel hub 25.
La figure 4 représente une variante de réalisation dans laquelle la roue est en position dite "tirée", alors que dans la réalisation précédente visible sur la figure 1 ainsi que sur la figure 5, la roue est en position dite "poussée". La différence entre la position "tirée" et la position "poussée" est due à une inversion du sens du triangle de suspension. Dans la position "tirée", l'articulation du bras de suspension est située en avant de l'axe de la fourche, alors que dans la position "poussée", l'articulation du bras de suspension est située en arrière de l'axe de la fourche. Comme précédemment, le dispositif de commande de direction 30 est monté sur un châssis 31 et comprend une fourche de direction 32 à laquelle est lié un ensemble tournant 33 qui comprend deux roues 34 montées sur un axe 35 solidaire d'un moyeu 36. Un triangle de suspension 37 se compose d'un élément de châssis 38 et d'un bras de suspension 39 articulé sur cet élément de châssis. Deux organes de suspension-amortisseurs 40 pneumatiques et mécaniques portent respectivement les moyeux 36 des roues 34. Un système de freinage- blocage en position 41 est monté sur le triangle de suspension 37. Ce système de freinage-blocage 41 comporte une pince de freinage 42 associée à un segment de disque de freinage 43. Ce mode de réalisation peut présenter des avantages pour certaines utilisations de la motocyclette en permettant de modifier la chasse et, par conséquent, le comportement routier du véhicule. Dans ce cas, la commande de freinage et le blocage en position restent totalement mécaniques, c'est-à-dire que le système de freinage-blocage comporte comme précédemment une poignée associée à un câble agissant sur des mâchoires de frein qui enserrent un segment de disque de freinage. FIG. 4 represents an embodiment variant in which the wheel is in the so-called "pulled" position, whereas in the previous embodiment visible in FIG. 1 as well as in FIG. 5, the wheel is in the so-called "pushed" position. The difference between the "pulled" position and the "pushed" position is due to a reversal of the direction of the wishbone. In the "pulled" position, the articulation of the suspension arm is located in front of the axis of the fork, whereas in the "pushed" position, the articulation of the suspension arm is located behind the axis. of the fork. As before, the steering control device 30 is mounted on a frame 31 and comprises a steering fork 32 to which is connected a rotating assembly 33 which comprises two wheels 34 mounted on an axis 35 integral with a hub 36. A triangle suspension 37 consists of a frame member 38 and a suspension arm 39 hinged to this frame member. Two pneumatic and mechanical suspension / damping members 40 respectively carry the hubs 36 of the wheels 34. A braking-locking system in position 41 is mounted on the wishbone 37. This braking-locking system 41 comprises a braking clamp 42 associated with a braking disk segment 43. This embodiment may have advantages for certain uses of the motorcycle by allowing to modify the hunting and, consequently, the road behavior of the vehicle. In this case, the braking control and the locking in position remain completely mechanical, that is to say that the braking-locking system comprises as above a handle associated with a cable acting on brake shoes that enclose a segment brake disc.
Dans une variante illustrée schématiquement par la figure 4A, les organes de suspension-amortisseurs 50 sont hydrauliques et fonctionnent également comme système de freinage-blocage hydraulique. A cet effet, les deux organes de suspension-amortisseurs 50, correspondant chacun à une des roues 34, sont alimentés en fluide hydraulique à travers une vanne à trois voies (non représentée) actionnée par les poignées de frein du véhicule. Le blocage en position verticale ou inclinée est alors obtenu par lesdits organes de suspension- amortisseurs 50. In a variant illustrated schematically in FIG. 4A, the suspension-shock absorber members 50 are hydraulic and also function as a hydraulic braking-locking system. For this purpose, the two suspension-damping members 50, each corresponding to one of the wheels 34, are supplied with hydraulic fluid through a three-way valve (not shown) actuated by the brake handles of the vehicle. The locking in vertical or inclined position is then obtained by said suspension-damping members 50.
La figure 5 représente un autre mode de réalisation du dispositif de commande de direction 30 selon l'invention. Ce dispositif comporte sensiblement les mêmes composants que celui de la figure 4. C'est pourquoi ils seront désignés par les mêmes références. Le positionnement du triangle de suspension 37 est inversé par rapport à celui de la construction précédente. Cette réalisation présente l'avantage de dégager un espace relativement important à l'avant du véhicule, ce qui lui permet de disposer d'une poche ou sacoche 51 relativement volumineuse pour charger des effets personnels ou des biens à transporter. Cette sacoche 51 comporte avantageusement, à sa partie inférieure, deux roulettes 52, un crochet d'accrochage 53 pour la suspendre à un élément du châssis et, à sa partie supérieure, un clapet de fermeture 54 pivotant. La forme et les dimensions de cette sacoche peuvent être modifiées en fonction de la motocyclette ou en fonction des dimensions que l'on souhaite lui donner. Elle est de préférence amovible, éventuellement fixée avec des moyens sécurisés, et a un profil qui est adapté au profil du carrossage de la motocyclette. Figure 5 shows another embodiment of the steering control device 30 according to the invention. This device comprises substantially the same components as that of Figure 4. That is why they will be designated by the same references. The positioning of the suspension triangle 37 is reversed relative to that of the previous construction. This embodiment has the advantage of releasing a relatively large space at the front of the vehicle; which allows him to have a pocket or bag 51 relatively bulky to load personal belongings or goods to carry. This bag 51 advantageously comprises, at its lower part, two wheels 52, a hook 53 for suspending a frame member and, at its upper part, a pivoting closure valve 54. The shape and dimensions of this bag can be modified depending on the motorcycle or depending on the size that you want to give it. It is preferably removable, possibly secured with secure means, and has a profile that is adapted to the camber profile of the motorcycle.
Possibilités d'application industrielle Possibilities of industrial application
Bien d'autres variantes de réalisation sont envisageables. La forme et les dimensions des différents composants peuvent être adaptées en fonction de la motocyclette concernée, de son profil, de sa puissance etc. Le dispositif de l'invention peut être conçu comme un accessoire susceptible de se substituer à une commande de direction d'origine pour améliorer la tenue de route et la capacité de transport d'une motocyclette traditionnelle commercialisée avec une seule roue directrice. Sans quasiment aucune modification technique de la motocyclette, le dispositif de l'invention peut être monté comme un accessoire et être substitué à la fourche télescopique de la motocyclette originale et réciproquement. De cette façon, la motocyclette peut avoir deux utilisations distinctes, l'une sportive et l'autre sécurisée pour une utilisation comme véhicule de ville. Les variantes envisagées restent toutefois dans le champ d'application des revendications et ne dépassent pas le cadre de la présente invention.  Many other embodiments can be envisaged. The shape and dimensions of the different components can be adapted according to the motorcycle concerned, its profile, its power etc. The device of the invention can be designed as an accessory that can replace an original steering control to improve the handling and carrying capacity of a traditional motorcycle marketed with a single steering wheel. Without virtually any technical modification of the motorcycle, the device of the invention can be mounted as an accessory and be substituted for the telescopic fork of the original motorcycle and vice versa. In this way, the motorcycle can have two distinct uses, one sporty and the other secured for use as a city vehicle. The alternatives contemplated, however, remain within the scope of the claims and do not go beyond the scope of the present invention.
