Description

VEHICULE DU TYPE MOTOCYCLETTE OU TRICYCLE  VEHICLE OF MOTORCYCLE OR TRICYCLE TYPE
Domaine technique Technical area
La présente invention concerne un véhicule du type motocyclette ou tricycle comportant un châssis central portant une première structure dé support d'une roue avant, appelée roue de direction, rotative autour d'un axe sensiblement horizontal et porté par ladite première structure, ledit axe de la roue avant étant lié à une tige de direction, et dans lequel ledit châssis central porte une seconde structure de suppor d'au moins une roue arrière.  The present invention relates to a vehicle of the motorcycle or tricycle type comprising a central frame carrying a first support structure of a front wheel, called a steering wheel, rotatable about a substantially horizontal axis and carried by said first structure, said axis of the front wheel being connected to a steering rod, and wherein said central frame carries a second suppor structure of at least one rear wheel.
Technique antérieure Prior art
Tous les véhicules du type motocyclettes ou similaires connus comportent un châssis servant à porter au moins une roue avant qui est la roue directrice, une roue arrière qui est la roue motrice, des organes d'entraînement motorisés qui sont couplés à ladite roue arrière motrice, des moyens de commande de la direction couplés à la roue avant directrice et des sièges pour le pilote et au moins un passager, qui sont montés sur le châssis.  All known vehicles of the motorcycle or similar type comprise a chassis for carrying at least one front wheel which is the steering wheel, a rear wheel which is the drive wheel, motorized drive members which are coupled to said rear drive wheel, steering control means coupled to the steering wheel and seats for the driver and at least one passenger, which are mounted on the chassis.
On connaît pertinemment le problème de stabilité et de maîtrise du pilotage de ce genre de véhicules sur des routes ordinaires, parce qu'il est bien connu que la traction arrière, si la puissance transmise à la roue motrice est mal dosée, en particulier sur-dosée, elle entraîne quasi immanquablement un dérapage difficile à rattraper, souvent suivi d'une chute qui peut avoir des conséquences tragiques. Pour remédier à ce problème une des solutions pourrait consister à remplacer le mode d'entraînement par propulsion par un mode d'entraînement par traction. Une telle transformation est habituellement difficile voire impossible à réaliser parce qu'il s'agit de concentrer à la fois la fonction direction et la fonction entraînement sur la même roue, ce qui reviendrait à connecter les organes de transmission du couple d'entraînement à la roue directrice qui est mobile angulairement. The problem of stability and control of the driving of such vehicles on ordinary roads is well known, because it is well known that the rear traction, if the power transmitted to the drive wheel is poorly dosed, in particular over- It almost inevitably leads to a skid that is difficult to catch up with, often followed by a fall that can have tragic consequences. To remedy this problem one of the solutions could be to replace the propulsion drive mode with a traction drive mode. Such a transformation is usually difficult or impossible to achieve because it is a question of concentrating both the steering function and the drive function on the same wheel, which would be equivalent to connecting the transmission members of the driving torque to the drive. steering wheel that is angularly mobile.
Cette solution a toutefois été mise en pratique sur le vélomoteur de la marque Solex™, il y a plus d'un demi-siècle, le moteur étant porté par la fourche de direction et les organes de transmission du couple comportant un rouleau de friction directement appuyé sur la surface du pneumatique de la roue avant qui devenait à la fois directrice et motrice. Il s'agissait bien d'un vélomoteur qui ne pouvait en aucune manière rivaliser avec un véhicule du type motocyclette. However, this solution was put into practice on the Solex ™ moped more than half a century ago, the engine being carried by the steering fork and the torque transmission members having a friction roller directly supported on the surface of the tire of the front wheel which became both steering and driving. It was a moped that could not compete with a motorcycle.
A ce jour, ce mode de réalisation n'a jamais été effectué, de sorte que le problème de la stabilité d'une motocyclette reste entier et que le mauvais contrôle du couple appliqué sur la roue motrice arrière reste dangereux. En outre, la motocyclette reste principalement dans nos régions, un véhicule à vocation sportive qui, dans la pratique se prête mal à une application utilitaire. Elle est de ce fait soumise aux mêmes règles que les véhicules automobiles et ne peut pas circuler sur des voies piétonnes, qui sont, dans certains cas praticables par des véhicules lents à voie étroite. La motocyclette est un véhicule étroit, mais n'entre pas dans la catégorie des véhicules lents, donc n'est pas autorisé à circuler sur une route piétonne ou similaire, même momentanément. To date, this embodiment has never been carried out, so that the problem of the stability of a motorcycle remains intact and the poor torque control applied to the rear drive wheel remains dangerous. In addition, the motorcycle remains mainly in our regions, a sporting vehicle that in practice is not well suited to a utility application. It is therefore subject to the same rules as motor vehicles and can not circulate on footpaths, which are in some cases passable by narrow-gauge slow vehicles. The motorcycle is a narrow vehicle, but does not fall into the category of slow vehicles, so it is not allowed to drive on a pedestrian road or the like, even momentarily.
Ces inconvénients pénalisent les véhicules de type motocyclette et limitent leur utilisation, alors qu'ils pourraient s'adapter à bien d'autres usages, comme l'accès à des voies étroites, ou le passage dans des secteurs routiers encombrés ou le transport de marchandises dans certaines zones de circulation spéciale. These disadvantages penalize motorcycle-type vehicles and limit their use, whereas they could be adapted to many other uses, such as access to narrow lanes, or passage in congested road sectors or the transport of goods. in certain areas of special traffic.
Exposé de l'invention Presentation of the invention
La présente invention se propose de pallier les inconvénients susmentionnés en permettant aux véhicules de type motocyclette ou de type tricycles de bénéficier d'une augmentation sensible de la stabilité et de ce fait d'améliorer leur sécurité par une forte limitation des risques de dérapage lorsque le dosage de la puissance transmise sur la ou les roues motrices est mal maîtrisé par le pilote. En outre leur utilisation pourrait être adaptée à d'autres applications, ce qui n'est pas le cas en raison de contraintes réglementaires en vigueur actuellement dans les territoires européens en particulier. Ces buts sont atteints par le véhicule tel que défini en préambule et caractérisé en ce que ladite première structure de support d'une roue avant comporte un élément recouvrant en forme de capot monté à l'avant du châssis central qui comporte à sa base une première couronne dentée fixe à l'intérieur de laquelle peut circuler une bague rotative qui est couplée avec l'axe, solidaire de la tige de direction qui porte un volant ou un guidon de direction et est fixée, à son extrémité inférieure, à l'axe de la roue directrice avant, dans lequel, ladite bague rotative porte un assemblage de composants dynamiques qui constituent les moyens d'entraînement mécaniques du véhicule, tractée par la roue avant directrice 12 qui est également une roue tractrice. The present invention proposes to overcome the aforementioned drawbacks by allowing motorcycle-type vehicles or tricycles-type vehicles to benefit from a significant increase in stability and thus to improve their safety by a strong limitation of the risks of skidding when the Dosing of the power transmitted on the driving wheel or wheels is poorly controlled by the pilot.

On notera que la tige de direction est inclinée par rapport au sol et sensiblement perpendiculaire par rapport au plan de la couronne dentée fixe 19. La tige de direction 17, porte un volant 18 ou un guidon de direction et est fixée, à son extrémité inférieure, à l'axe 14 de la roue directrice avant 12.  The vehicle 10 of the motorcycle type, according to Figure 1 advantageously comprises a central frame 11, having a first structure 11a for supporting a steering wheel 12 leading, and a second structure 11 b for supporting a free rear wheel 13. The first support structure 11a of the steering wheel 12 carries an axis 14, which is arranged horizontally. The first structure 11a which is associated with the central frame 11, comprises a substantially domed or substantially semi-spherical cap member 15 which overhangs and protects in particular the front wheel 12 which is the steering wheel of the vehicle 10. covering member 15 in the form of a cover is mounted at the front of the central frame 11. It comprises at its base a first fixed ring gear 19 inside which can circulate a rotary ring 20 which is coupled with the axis 14 , integral with a steering rod 17. Note that the steering rod is inclined relative to the ground and substantially perpendicular to the plane of the fixed ring gear 19. The steering rod 17, carries a steering wheel 18 or a handlebar direction and is fixed at its lower end to the axis 14 of the front steering wheel 12.
La bague rotative 20 porte un assemblage de composants dynamiques qui constituent les moyens d'entraînement mécaniques du véhicule, tractée par la roue avant directrice 12 qui est également une roue tractrice, qui a pour avantage de rendre le véhicule 10, qui est a priori une motocyclette, un véhicule à traction avant. Les composants dynamiques comportent en vrac, et bien qu'ils ne soient pas décrits en détail ni représentés par le dessin, un bloc moteur comportant un arbre moteur agencé pour être couplé à l'axe 14 de la roue avant 12, des moyens de transmission pour coupler l'arbre moteur avec l'axe 14 de ladite roue avant 12, des organes de freinage, un organe de support 21 pour porter l'axe 14 de la roue 14 et la rendre solidaire de la colonne de direction 17 et des moyens de suspension pour assurer la suspension de la roue avant 12 par rapport au châssis central 11 , On notera que la roue avant 12 qui est montée sur la bague rotative 20 est directement couplée avec les composants dynamiques du véhicule qui sont également montés sur ladite bague rotative 20, de sorte que la roue avant est la roue motrice et que la motocyclette 10 est un véhicule du type à traction avant. Ce concept est totalement différent de celui des motocyclettes traditionnelles qui sont poussées par la roue arrière qui est motrice alors que la roue avant n'a qu'une fonction directrice. Cette modification du concept par rapport aux véhicules du type motocyclette connus entraîne des modifications constructives importantes, sachant que tous les organes mécaniques qui interviennent pour assurer l'entraînement, le freinage, la transmission doivent obligatoirement être disposés de manière à pourvoir coopérer et communiquer avec la roue motrice, à savoir la roue avant 12. Ils doivent de ce fait être portés par le support de l'assemblage de composants dynamiques et qui est monté sur la bague rotative 20 de l'organe de roulement 14 avec sa couronne dentée fixe 19 solidaire dudit châssis 11. The rotary ring 20 carries an assembly of dynamic components that constitute the mechanical drive means of the vehicle, pulled by the steering wheel 12 which is also a tractive wheel, which has the advantage of making the vehicle 10, which is a priori a motorcycle, a front-wheel drive vehicle. The dynamic components comprise in bulk, and although they are not described in detail or represented by the drawing, an engine block comprising a motor shaft arranged to be coupled to the axis 14 of the front wheel 12, transmission means to couple the motor shaft with the axis 14 of said front wheel 12, braking members, a support member 21 for carrying the axis 14 of the wheel 14 and make it integral with the steering column 17 and means suspension for ensuring the suspension of the front wheel 12 relative to the central frame 11, It will be noted that the front wheel 12 which is mounted on the rotary ring 20 is directly coupled with the dynamic components of the vehicle which are also mounted on said rotary ring 20, so that the front wheel is the drive wheel and the motorcycle 10 is a front-drive type vehicle. This concept is totally different from that of traditional motorcycles that are pushed by the rear wheel which is driving while the front wheel has a guiding function. This modification of the concept with respect to known motorcycle-type vehicles involves significant constructive modifications, knowing that all the mechanical devices that intervene to ensure the drive, the braking, the transmission must necessarily be arranged so as to be able to cooperate and communicate with the vehicle. driving wheel, namely the front wheel 12. They must therefore be carried by the support of the assembly of dynamic components and which is mounted on the rotary ring 20 of the rolling member 14 with its fixed ring gear 19 secured of said chassis 11.
Dans l'exemple décrit ci-dessus, le véhicule 10, selon le premier mode de réalisation, comporte une seule roue avant 12 et une seule roue arrière 13 et le véhicule 10 a un aspect classique de motocyclette, avec néanmoins un caractère spécifique qui est la fonction tractrice de la roue motrice et directrice 12 et la fonction suiveuse de la roue arriérai 3. In the example described above, the vehicle 10, according to the first embodiment, comprises a single front wheel 12 and a single rear wheel 13 and the vehicle 10 has a classic motorcycle appearance, with nevertheless a specific character which is the tractive function of the driving and steering wheel 12 and the following function of the rear wheel 3.
Le véhicule 10 comporte par ailleurs, sur le châssis central 11 , par exemple une selle 22 pour le pilote du véhicule et un siège 23 à l'arrière pour un passager. Le siège 23 pourrait être remplacé par un porte bagages ou similaire. The vehicle 10 further comprises, on the central frame 11, for example a saddle 22 for the driver of the vehicle and a seat 23 at the rear for a passenger. The seat 23 could be replaced by a luggage rack or the like.
Le véhicule 30 sous la forme d'un tricycle, selon la figure 2 comporte également un châssis central 31 , comportant une première structure de support 31a d'une roue avant directrice 32 et une seconde structure 31b, de support de deux roues arrières libres 33. La première structure 31a de support de la roue avant directrice 32 est identique à la première structure 11a de support de la roue avant 12 selon la réalisation de la figure 1 et porte un axe 34, qui est disposé horizontalement. La première structure 31a qui est associée au châssis central 31, comporte un élément recouvrant 35, en forme de dôme ou de capot sensiblement semi-sphérique, qui surplombe et protège en particulier la roue avant 32 qui est la roue directrice du véhicule 30. L'élément recouvrant 35 en forme de capot est monté à l'avant du châssis central 31 , et, comme pour la réalisation de la figure 1 , est couplé à une tige de direction, qui se termine par un volant (non représenté) ou un guidon de direction. La tige de direction est fixée, à son extrémité inférieure, à l'axe 34 de la roue avant 32. The vehicle 30 in the form of a tricycle, according to Figure 2 also comprises a central frame 31, comprising a first support structure 31a of a leading wheel 32 and a second structure 31b, supporting two rear wheels free 33 The first support structure 31a of the steering wheel 32 is identical to the first support structure 11a of the front wheel 12 according to the embodiment of Figure 1 and carries an axis 34, which is arranged horizontally. The first structure 31a which is associated with the central frame 31, comprises a substantially domed or substantially semi-spherical cap-like element 35 which overhangs and protects in particular the front wheel 32 which is the steering wheel of the vehicle 30. covering element 35 in the form of a hood is mounted in front of the central frame 31, and, as for the embodiment of Figure 1, is coupled to a steering rod, which ends with a steering wheel (not shown) or a steering handlebar. The steering rod is fixed at its lower end to the axis 34 of the front wheel 32.
L'élément recouvrant 35 en forme de capot comporte à sa base une couronne dentée fixe 39 à l'intérieur de laquelle peut circuler une bague rotative qui est couplée avec l'axe 34, solidaire de la tige de direction. On notera que la tige de direction est inclinée par rapport au sol et sensiblement perpendiculaire par rapport au plan de la couronne dentée fixe 39. The covering element 35 in the form of a hood has at its base a fixed ring gear 39 inside which can circulate a rotating ring which is coupled with the axis 34, integral with the steering rod. Note that the steering rod is inclined relative to the ground and substantially perpendicular to the plane of the fixed ring gear 39.
La bague rotative porte un assemblage de composants dynamiques 40 qui constituent les moyens d'entraînement mécaniques du véhicule 30, tracté par la roue avant directrice 32 qui est également une roue tractrice, ce qui a pour avantage de rendre le véhicule 30, qui est a priori une motocyclette, un véhicule à traction avant. Les composants dynamiques comportent en vrac, et bien qu'ils ne soient pas décrits en détail ni représentés par le dessin, un bloc moteur comportant un arbre moteur agencé pour être couplé à l'axe 34 de la roue avant 32, des moyens de transmission pour coupler l'arbre moteur avec l'axe 34 de ladite roue avant 32, des organes de freinage, un organe de support pour porter l'axe 34 de la roue 32 et la rendre solidaire de la colonne de direction et des moyens de suspension pour assurer la suspension de la roue avant 32 par rapport au châssis central 31. La rotation du volant et de la colonne de direction commande le déplacement de la roue 32 sous le capot 39, en entraînant tous les composants dynamiques, tels que le moteur de traction du véhicule, les éléments amortisseurs, les moyens de freinage et la batterie électrique. The rotary ring carries an assembly of dynamic components 40 which constitute the mechanical drive means of the vehicle 30, towed by the steering wheel 32 which is also a tractive wheel, which has the advantage of making the vehicle 30, which is a a motorcycle, a front-wheel drive vehicle. The dynamic components comprise in bulk, and although they are not described in detail or represented by the drawing, an engine block comprising a motor shaft arranged to be coupled to the axis 34 of the front wheel 32, transmission means to couple the motor shaft with the axis 34 of said front wheel 32, braking members, a support member for carrying the axis 34 of the wheel 32 and make it integral with the steering column and the suspension means to ensure the suspension of the front wheel 32 relative to the central frame 31. The rotation of the steering wheel and the steering column controls the movement of the wheel 32 under the cover 39, driving all the dynamic components, such as the engine of traction of the vehicle, the damping elements, the braking means and the electric battery.
Le secteur postérieur 31b se compose d'un organe transversal 38, monté perpendiculairement et symétriquement à l'extrémité arrière du châssis central 31 , et qui porte à chacune de ses extrémités latérales, une roue arrière 33. De ce fait le véhicule 30 comporte une roue avant 32 directrice et tractrice et deux roues arrières 33 libres, montées latéralement aux deux extrémités de l'organe transversal 38. L'organe transversal 38 est équipé de deux bras télescopiques latéraux 38a et 38b, disposés de part et d'autre de l'organe transversal 38 et qui permettent de modifier l'écartement des deux roues arrières 33, en modifiant la voie du véhicule 30. The posterior sector 31b consists of a transverse member 38, mounted perpendicularly and symmetrically to the rear end of the central frame 31, and which carries at each of its lateral ends, a rear wheel 33. As a result, the vehicle 30 comprises a front wheel 32 director and tracer and two rear wheels 33 free, mounted laterally at both ends of the body transverse member 38. The transverse member 38 is equipped with two lateral telescopic arms 38a and 38b disposed on either side of the transverse member 38 and which make it possible to modify the spacing of the two rear wheels 33, by modifying the track of the vehicle 30.
En outre le véhicule 30 comporte des moyens qui permettent de commander un écartement latéral des roues arrières 33 pour augmenter la stabilité sur la route du véhicule 30. Le faible écartement des roues arrières 33 permet au véhicule de passer sur des voies étroites ou de se faufiler entre des véhicules sur une route encombrée, alors que l'écartement plus important des roues arrières permet au véhicule 33 de bénéficier d'une meilleur tenue de route sur des voies dégagées et d'augmenter la sécurité soutière à grande vitesse. Cette modification de la voie du véhicule peut être effectuée en pleine circulation, par une commande effectuée sur le véhicule et a pour avantage d'attribuer au véhicule une première fonction routière, lorsqu'il est en voie large et une seconde fonction utilitaire, lorsqu'il est en voie étroite, lui permettant de circuler à vitesse limitée sur Ses trottoirs ou des rues piétonnes. En mode utilitaire, le véhicule peut par exemple être utilisé par la poste pour distribuer le courrier ou pour accéder à des habitations des centres de villes desservies par des voies étroites, ou plus généralement de contourner des embouteillages qui bloquent momentanément un passage routier en permettant un accès sur un trottoir réservé habituellement aux piétons. In addition, the vehicle 30 comprises means which make it possible to control a lateral spacing of the rear wheels 33 to increase the stability on the road of the vehicle 30. The small spacing of the rear wheels 33 allows the vehicle to pass on narrow lanes or to sneak between vehicles on a congested road, while the greater spacing of the rear wheels allows the vehicle 33 to benefit from better handling on open roads and to increase the security of the high speed. This modification of the vehicle lane can be effected in full circulation, by a command made on the vehicle and has the advantage of attributing to the vehicle a first road function, when it is in wide lane and a second utility function, when it is narrow gauge, allowing it to travel at limited speed on sidewalks or pedestrian streets. In the utility mode, the vehicle can for example be used by the post office to deliver mail or to access dwellings in city centers served by narrow lanes, or more generally to circumvent traffic jams that momentarily block a road crossing by allowing a access on a sidewalk usually reserved for pedestrians.
L'organe central 38 peut être équipé d'un support de type porte-bagages ou d'un petit coffre équipé d'un couvercle qui se ferme à l'aide d'une serrure, ce qui apporte des avantages complémentaires à la fonction utilitaire, notamment pour la distribution du courrier, la livraison d'articles de petite dimension par des entreprises de livraison ou de distribution, la collecte de produits ou d'échantillons pour des analyses, 1e rangement d'objets personnels du conducteur ou du passager ou pour toute intervention urgente sur des sites difficiles d'accès, comme dans des centres urbains ou des zones rurales mal desservies par les infrastructures classiques. Les véhicules selon l'invention sont susœptibles d'évoluer en fonction de besoins spécifiques, de sorte que l'invention n'est pas limitée aux formes de réalisations décrites ou à leurs variantes, mais peut s'étendre à des extensions qui restent cependant inscrites dans le cadre défini par les revendications. The central member 38 can be equipped with a rack-type support or a small trunk with a lid that closes with a lock, which brings additional benefits to the utility function. , in particular for the distribution of mail, the delivery of small articles by delivery or distribution companies, the collection of products or samples for analysis, the storage of personal belongings of the driver or the passenger or for any urgent intervention on hard-to-access sites, such as in urban centers or rural areas that are poorly served by conventional infrastructure. The vehicles according to the invention are susoptibles to evolve according to specific needs, so that the invention is not limited to the forms of embodiments described or their variants, but can extend to extensions that remain however listed within the scope defined by the claims.
