Description

Des véhicules motorisés et roulant suspendus à une voie sont utilisés depuis plusieurs décennies déjà. Mais l'extension de leur utilisation ne s'est pas produite comme espéré, vraisemblablement du fait que leur voie de roulement, constituée par des éléments rigides, nécessite un grand nombre du pylônes ou de portiques supports impliquant une forte emprise au sol, rendant ce système aussi onéreux que les autres moyens de transports publics urbains connus et expérimentés tels que tramways, autobus, trolleybus, etc.Motorized and rolling vehicles suspended from a track have been used for several decades. But the extension of their use did not occur as hoped, probably because their track, constituted by rigid elements, requires a large number of pylons or gantry supports implying a strong footprint, making this a system as expensive as other known and experienced means of urban public transport such as trams, buses, trolleybuses, etc.

Récemment, des systèmes de véhicules suspendus sont apparus, la voie de roulement étant constituée d'un ou plusieurs câbles disposés horizontalement et fortement tendus. Les pylônes suportant ces câbles sont prolongés vers le haut, et au moins un second câble également tendu, dessine un feston au-dessus du premier câble qui est relié au second par des brins verticaux en utilisant le même principe que celui des ponts suspendus. Cette disposition constructive a pour conséquence d'autoriser de grandes portées de câbles, les pylônes pouvant être placés a plusieurs centaines de mètres l'un de l'autre. Il en résulte donc une, très forte réduction de l'emprise au aol, des travaux de fondation nécessaires, du poids des superstructures, par conséquent de coût de l'installation. Il est évident que ce système est surtout avantageux pour les trajectoires rectilignes et n'autorise que de très faibles courbures. Les zones de parcours comportant de fortes courbures doivent être construites différemment en recourant par exemple, à des voies rigides portées par des pylônes, des portiques.Recently, suspended vehicle systems have appeared, the track being made up of one or more cables arranged horizontally and highly tensioned. The pylons supporting these cables are extended upwards, and at least a second cable also stretched, draws a festoon above the first cable which is connected to the second by vertical strands using the same principle as that of suspension bridges. This constructive arrangement has the effect of authorizing large spans of cables, the pylons being able to be placed several hundred meters from each other. This therefore results in a very significant reduction in the footprint with aol, the necessary foundation work, the weight of the superstructures, and consequently the cost of installation. It is obvious that this system is especially advantageous for rectilinear trajectories and allows only very slight curvatures. Course areas with strong curvatures must be constructed differently, for example by using rigid tracks carried by pylons, gantries.

Mais le système de voies constituées essentiellement de câbles horizontaux fortement tendus et supportés d'une part par des appuis .sur pylônes et d'autre part par des brins verticaux attachés à un câble supérieur, présente de grandes élasticités aussi bien dans les plans vertical qu'horizontal. La présence de masses en mouvement sur cette voie entraîne un risque important de vibrations dont les fréquences pourraient entrer en résonnance avec celles propres de la voie, dont chaque brin vertical induit un changement de direction du câble de roulement et constitue une excitation vibratoire dont la fréquence est égale à la vitesse d'avancement mesurée en m/s divisée par le pas des brins, exprimé en m.However, the system of tracks essentially made up of highly stretched horizontal cables and supported on the one hand by supports on pylons and on the other hand by vertical strands attached to an upper cable, has great elasticities both in the vertical planes and 'horizontal. The presence of masses in motion on this track involves a significant risk of vibrations whose frequencies could come into resonance with those specific to the track, whose each vertical strand induces a change of direction of the running cable and constitutes a vibratory excitation whose frequency is equal to the forward speed measured in m / s divided by the pitch of the strands, expressed in m.

Le but de la présente invention est de remédier aux inconvénients cités, en réduisant l'effet des brins, et par ailleurs d'améliorer la stabilité du roulement par l'utilisation de roues indépendantes aussi bien en rotation qu'en suspension.The object of the present invention is to remedy the drawbacks mentioned, by reducing the effect of the strands, and moreover to improve the stability of the bearing by the use of independent wheels both in rotation and in suspension.

Plus précisément l'invention concerne un véhicule de transport de personnes et/ou de marchandises comportant une caisse suspendue à des roues dont certaines sont motrices et qui roulent sur deux pistes disposées l'une à côté de l'autre, l'écartement entre elles étant constant, caractérisé en ce que le véhicule est pendu aux pistes par l'intermédiaire d'une pièce centrale en forme de fourche à deux dents dirigées vers le haut qui enveloppent les pistes, le plan passant par les axes des dents étant perpendiculaire à la direction longitudinale des pistes, où chaque extrémité de dent comporte une articulation à axe horizontal autour de laquelle pivote un balancier dans un plan vertical parallèle à la piste correspondante, les extrémités de chaque balancier comportant une roue montée par l'intermédiaire d'un palier qui roule sur la piste correspondante et où la fourche est reliée en son milieu à la caisse du véhicule. par l'intermédiaire d'une butée pivotant autour d'un axe vertical.More specifically, the invention relates to a vehicle for transporting people and / or goods comprising a body suspended from wheels, some of which are driving and which run on two tracks arranged one next to the other, the spacing between them. being constant, characterized in that the vehicle is hung from the tracks by means of a central piece in the form of a fork with two teeth directed upwards which envelop the tracks, the plane passing through the axes of the teeth being perpendicular to the longitudinal direction of the tracks, where each tooth end has a joint with a horizontal axis around which pivots a pendulum in a vertical plane parallel to the corresponding track, the ends of each pendulum comprising a wheel mounted by means of a bearing which rolls on the corresponding track and where the fork is connected in the middle to the vehicle body. by means of a stop pivoting about a vertical axis.

Là figure 1 représente les éléments constitutifs de la voie, vue en élévation et constituée de deux pistes, chacune comportant un ou plusieurs câbles fortement tendus horizontalement. Ces câbles sont recouverts d'un rail de roulement 16, mince afin d'éviter l'usure du câble proprement dite, au cours du service d'exploitation des véhicules. Sur chacune de ces . pistes les roues du . véhicules roulent ainsi qu'on le verra plus loin. Les deux pistes sont reliées l'une à l'autre, comme le montre la figure 5, par un support en T inversé dont la barre horizontale porte les câbles de roulement 15 surmontés du rail de protection 16; dans le cas de la figure deux câbles 15 ont été représentés pour chaque piste, mais. il aurait été possible d'atteindre le même but en utilisant soit un seul câble de plus grand diamètre, soit en montant un plus grand nombre de câbles de diamètre réduit. Chaque support de liaison en T inversé 19 est attaché en son axe médian au câble porteur 3 par un brin 4.. Le câble porteur 3 dessine un feston au-dessus du câble des voies de roulement, l'ensemble présentant la même image qu'un pont suspendu conventionnel. Ce type de construction de voie de roulement permet de placer celle-ci dans des zones construites, n'exigeant qu'une emprise au sol extrêmement réduite, celle correspondant aux pylônes. Il va de soi que chacun de ces câbles doit être pré-tendu en permanence, de telle façon que la piste de roulement reste sensiblement horizontale, malgré le passage du véhicule. Cette construction a des avantages très importants car la distance entre deux pylônes consécutifs peut être très grande, de plusieurs centaines de mètres.There figure 1 represents the constituent elements of the track, seen in elevation and made up of two tracks, each comprising one or more cables strongly stretched horizontally. These cables are covered with a thin running rail 16 in order to prevent wear of the cable proper, during vehicle operation service. On each of these. tracks the wheels of the. vehicles drive as we will see later. The two tracks are connected to each other, as shown in FIG. 5, by an inverted T-shaped support whose horizontal bar carries the running cables 15 surmounted by the protective rail 16; in the case of the figure two cables 15 have been shown for each track, but. it would have been possible to achieve the same goal by using either a single cable of larger diameter, or by mounting a greater number of cables of reduced diameter. Each inverted T connection support 19 is attached in its median axis to the support cable 3 by a strand 4 .. The support cable 3 draws a festoon above the track cable, the assembly having the same image as a conventional suspension bridge. This type of track construction makes it possible to place it in built-up areas, requiring only an extremely small footprint, that corresponding to the pylons. It goes without saying that each of these cables must be permanently pre-tensioned, so that the raceway remains substantially horizontal, despite the passage of the vehicle. This construction has very important advantages because the distance between two consecutive pylons can be very large, several hundreds of meters.

Cette voie peut également servir au passage de zones humides (marais, fleuves) où le pylône peut être posé sur un radeau convenablement amarré. La trajectoire des pistes portées par des câbles doit être dans un plan vertical, du fait des tensions initiales auxquelles les câbles 2 et 3 sont soumis.This route can also be used to pass through wetlands (marshes, rivers) where the pylon can be placed on a properly moored raft. The trajectory of the tracks carried by cables must be in a vertical plane, because of the initial tensions to which cables 2 and 3 are subjected.

Cependant, de légères courbures sont possibles; il n'est pas indispensable que les pylônes 1 soient alignés rigoureusement le long d'une droite. Mais le système décrit ci-dessus ne permet pas le passage de courbes de petit rayon. La construction doit être différente et semblable à celle représentée aux figures 2 et 3. Le roulement ne se fait alors -plus sur des câbles tendus à des brins, mais sur des voies de roulement 2 portées par une poutre longitudinale 7 représentée ici en forme de double T, maintenue en position par des portiques 6 supportés par des poteaux 5. D'autres façons de supporter la poutre 7 auraient été possibles, par. exemple en la supportant par une potence.However, slight bends are possible; it is not essential that the pylons 1 be rigorously aligned along a straight line. However, the system described above does not allow the passage of small radius curves. The construction must be different and similar to that shown in Figures 2 and 3. The rolling is then done - no longer on cables stretched to strands, but on rolling tracks 2 carried by a longitudinal beam 7 shown here in the form of double T, held in position by gantries 6 supported by posts 5. Other ways of supporting the beam 7 would have been possible, par. example by supporting it with a gallows.

La figure 3, qui est une vue en travers de la figure 2, montre la disposition des pistes de roulement 2 qui est la même que celles selon figure 1. Le passage d'un système à l'autre se fait progressivement, la vitesse du véhicule devant être adaptée dans les courbes selon les nécessités de celles-ci. La figure 3 montre également que les roues 11 sont attachées l'une à l'autre par l'intermédiaire d'une fourche 8 à deux dents 9 qui portent ces roues. Cette fourche est reliée aux caisses du véhicule par l'intermédiaire d'une liaison sphérique 20.Figure 3, which is a cross view of Figure 2, shows the arrangement of the raceways 2 which is the same as those according to Figure 1. The transition from one system to another is done gradually, the speed of vehicle to be adapted in the curves according to the needs thereof. Figure 3 also shows that the wheels 11 are attached to each other by means of a fork 8 with two teeth 9 which carry these wheels. This fork is connected to the vehicle bodies via a spherical link 20.

La figure 4 représente en perspective le fonctionnement des balanciers et d'une fourche d'un train de roues. La fourche 8 comporte deux dents verticales 9 aux extrémités desquelles sont fixées les articulations 18 des balanciers 12. Autour de ces articulations, pivotent de chaque côté dans un plan vertical, les balanciers 12 portant à chacune des extrémités une roue 11 par l'intermédiaire d'un palier de roue 13, facilitant sa rotation sur son axe. Le manche de la fourche 10 représenté ici, pour la clarté du dessin, sous la fourche, est attaché au véhicule par une liaison sphérique. Ce dispositif de train de roues présente l'avantage, quelle que soit la forme de la voie de roulement, d'équilibrer les charges agissant sur les roues avant et arrière du train de roues. En effet, étant portée par des balanciers articulés en leur point milieu, la charge se répartit automatiquement. Ce dispositif a pour conséquence de réduire L'effet des non-linéarités se présentant le long de la voie de roulement. Les pistes de celle-ci sont portées dans l'espace par l'intermédiaire de brins distant les uns des autres de quelques mètres. Elles présentent une flexion différente lorsque la charge se trouve entre deux brins 4 et lorsqu'elle se trouve au droit d'un brin 4. Cette discontinuité est de nature à induire les vibrations dans la suspension du véhicule, vibrations qui sont considérablement réduites ici par l'augmentation du nombre de roues porteuses.Figure 4 shows in perspective the operation of the pendulums and a fork of a wheel train. The fork 8 has two vertical teeth 9 at the ends of which the articulations 18 of the pendulums 12 are fixed. Around these articulations, pivot on each side in a vertical plane, the pendulums 12 carrying at each end a wheel 11 by means of 'a wheel bearing 13, facilitating its rotation on its axis. The handle of the fork 10 shown here, for clarity of the drawing, under the fork, is attached to the vehicle by a spherical connection. This wheel train device has the advantage, whatever the shape of the track, of balancing the loads acting on the front and rear wheels of the wheel train. Indeed, being carried by pendulums articulated at their midpoint, the load is distributed automatically. The effect of this arrangement is to reduce the effect of the non-linearities occurring along the track. The tracks of this one are carried in space by the intermediary of strands distant from each other of a few meters. They have a different bending when the load is between two strands 4 and when it is at the level of a strand 4. This discontinuity is likely to induce vibrations in the suspension of the vehicle, vibrations which are considerably reduced here by increasing the number of load wheels.

La figure 5 représente une vue en élévation de la fourche. Dans le cas particulier, le manche de la fourche au lieu d'être disposé dans une direction différente des dents 9, va dans le même sens qu'elles. Cette figure représente la liaison sphérique 20 composée de deux pièces posées l'une sur l'autre et attachées à la fourche par l'intermédiaire de 4 vis de fixation 27 et deux supports 49 fixés aux dents 9 et disposés sous les balanciers 12 au-dessus des pistes 2 de la voie de roulement. Normalement, un jeu subsiste entre ces supports anti-chute et cette voie. En cas d'incident à l'une ou l'autre des roues, rupture, déraillement, le support entre en coutact avec la voie et évite la chute du véhicule.Figure 5 shows an elevational view of the fork. In the particular case, the handle of the fork instead of being arranged in a different direction from the teeth 9, goes in the same direction as them. This figure represents the spherical connection 20 composed of two pieces placed one on the other and attached to the fork by means of 4 fixing screws 27 and two supports 49 fixed to the teeth 9 and arranged under the pendulums 12 au- above tracks 2 of the track. Normally, a clearance remains between these anti-fall supports and this path. In the event of an incident on one or other of the wheels, rupture, derailment, the support comes into contact with the track and prevents the vehicle from falling.

La figure 6 est une vue de profil d'un train de roues comportant 8 roues. Le fonctionnement est le même que précédemment. Le balancier principal 12 au lieu de porter à ses extrémités des roues, porte des balanciers auxiliaires 21 aux extrémités desquelles sont fixées des roues 11. Les bras de leviers pour chaque type de balancier 21 et 12 sont égaux, ainsi que les diamètres des roues 11. Toutes les roues de ce train portent une charge identique et sont mobiles dans un plan vertical. Cette disposition a l'avantage de réduire considérablement les effets de discontinuité dans le tracé de .la voie. Cette réduction de l'effet provoque une augmentation de la fréquence propre d'excitation qui, dans le cas particulier, est favorable puisqu'elle autorise une augmentation de la vitesse du véhicule avant d'atteindre la fréquence de résonnance de l'ensemble.Figure 6 is a side view of a wheel train having 8 wheels. The operation is the same as before. The main balance 12 instead of carrying wheels at its ends, carries auxiliary balance 21 at the ends of which are fixed wheels 11. The lever arms for each type of balance 21 and 12 are equal, as are the diameters of the wheels 11 All the wheels on this train carry an identical load and are movable in a vertical plane. This arrangement has the advantage of considerably reducing the effects of discontinuity in the layout of the track. This reduction in the effect causes an increase in the natural excitation frequency which, in the particular case, is favorable since it allows an increase in the speed of the vehicle before reaching the resonant frequency of the assembly.

La figure 7 est une vue en plan et en détail de la liaison sphérique 20 dont la moitié supérieure a été démontée. Cette liaison comprend une tête de châssis 23 solidaire du châssis 33 qui se prolonge en 25 par une calotte sphérique de traction qui se termine par une calotte sphérique de poussée 24. La disposition est symétrique pour deux châssis consécutifs. Les deux calottes sphériques 25 sont inscrites dans une sphère 26, les extrémités des calottes 24 prenant appui l'une contre l'autre. La sphère 26 d'inscription des calottes est constituée par le corps de liaison 20 qui comprend deux pièces coupant cette sphère en deux hémisphères. Une liaison de ce type permet tout mouvement d'oscillation autour de son centre des deux extrémités 23 des châssis 33 l'un par rapport à l'autre, que cette oscillation se produise dans un plan vertical ou horizontal. La distance entre ces deux châssis est maintenue constante et le corps portant la sphère inscrite 20 qui est fixé à la fourche peut pivoter autour d'un axe vertical passant par ce centre. Cette liaison est précisément celle qui se trouve portée par.la fourche 8, elle constitue donc une articulation des deux châssis l'un par rapport à l'autre, et permet à la fourche porteuse des châssis de pivoter autour d'un axe vertical, et de s'orienter suivant la trajectoire et les courbes de la voie de roulement.FIG. 7 is a plan view and in detail of the spherical connection 20 of which the upper half has been dismantled. This connection comprises a chassis head 23 integral with the chassis 33 which is extended at 25 by a spherical traction cap which ends in a spherical thrust cap 24. The arrangement is symmetrical for two consecutive chassis. The two spherical caps 25 are inscribed in a sphere 26, the ends of the caps 24 bearing one against the other. The sphere 26 for registering the caps is constituted by the connecting body 20 which comprises two parts cutting this sphere into two hemispheres. A link of this type allows any oscillation movement around its center of the two ends 23 of the frames 33 relative to one another, whether this oscillation occurs in a vertical or horizontal plane. The distance between these two frames is kept constant and the body carrying the inscribed sphere 20 which is fixed to the fork can pivot around a vertical axis passing through this center. This connection is precisely that which is carried by the fork 8, it therefore constitutes an articulation of the two chassis with respect to each other, and allows the fork carrying the chassis to pivot around a vertical axis, and to orient oneself along the trajectory and curves of the track.

La figure 8 représente un dispositif de liaison liant deux tronçons de véhicule consécutifs afin qu'ils restent en permanence dans un bon alignement. Suivant le trajet, il est nécessaire que ces tronçons de caisse puissent parfois s'éloigner, respectivement se rapprocher l'un de l'autre. A cet effet, cette liaison est réalisée par une bielle 30 attachée à chacune de ses extrémités à chacun des tronçons 28 du véhicule par des articulations 31 et des supports de bielle 32. Ce dispositif autorise l'allongement et le raccourcissement de l'espace existant entre deux tronçons de caisse, mais s'oppose à tout déplacement transversal relatif. Les tronçons de caisse sont reliés les uns aux autres par les soufflets habituels pour des véhicules de ce genre, soufflets bien connus et utilisés notamment sur les tramways et autobus articulés.FIG. 8 represents a connecting device linking two consecutive vehicle sections so that they remain permanently in good alignment. Depending on the route, it is necessary that these body sections can sometimes move away, respectively approach each other. To this end, this connection is made by a connecting rod 30 attached to each of its ends to each of the sections 28 of the vehicle by articulations 31 and connecting rod supports 32. This device allows the existing space to be lengthened and shortened. between two body sections, but opposes any relative transverse movement. The body sections are connected to each other by the usual bellows for vehicles of this kind, bellows well known and used in particular on articulated trams and buses.

La figure 9 montre l'ensemble du véhicule selon l'invention, chaque tronçon de caisse 28 comporte un châssis 33 fixé sur son toit, châssis dont l'extrémité 23 correspond à celle représentée à la figure 7. Ces extrémités sont reliées les unes aux autres par les liaisons sphériques 20 qui elles, sont attachées au milieu de la fourche 8. Ainsi l'ensemble est articulé autorisant le véhicule à passer des courbes de petit . rayon et des changements de direction dans le plan vertical. Chacune des fourches 8 étant libre autour d'un axe vertical, chaque train de roues est guidé par la voie et s'oriente de telle façon que sa direction de roulement corresponde à l'axe longitudinal de la voie à l'endroit où il se trouve. La figure mentionne encore un dispositif complémentaire représenté par une bielle auxiliaire 36 qui est attachée par une articulation 37 au châssis 33 et qui porte à son autre extrémité un palier de guidage entourant l'axe du guidage 34 solidaire de la fourche. Ce palier a pour effet de maintenir constamment en position verticale l'axe de la fourche, cet axe étant tenu entre ce palier et la liaison sphérique 20.FIG. 9 shows the entire vehicle according to the invention, each body section 28 comprises a chassis 33 fixed on its roof, chassis whose end 23 corresponds to that shown in FIG. 7. These ends are connected to each other. others by the spherical links 20 which are attached to the middle of the fork 8. Thus the assembly is articulated allowing the vehicle to pass small curves. radius and direction changes in the vertical plane. Each of the forks 8 being free around a vertical axis, each set of wheels is guided by the track and is oriented in such a way that its rolling direction corresponds to the longitudinal axis of the track at the point where it find. The figure also mentions an additional device represented by an auxiliary connecting rod 36 which is attached by a hinge 37 to the chassis 33 and which carries at its other end a guide bearing surrounding the axis of the guide 34 secured to the fork. The effect of this bearing is to constantly maintain the axis of the fork in a vertical position, this axis being held between this bearing and the spherical connection 20.

Dans une autre forme d'exécution selon figure 10, au lieu de réaliser le véhicule avec des liaisons sphériques et des châssis articulés les uns par rapport aux autres, il est possible de surmonter les divers tronçons de caisse par un profilé 38 d'une seule pièce liant tous les paliers de butée 39 qui sont attachés à la fourche 8. Cette liaison est moins souple que la précédente, mais en considérant les grandes longueurs en présence et les faibles courbures de la voie, le profilé 38 est choisi de telle façon qu'ils soit suffisamment souple pour se déformer par flexion et s'adapter à la voie quel que soit sont tracé. Ce dispositif a l'avantage d'être plus simple (donc moins coûteux) que le précédent, mais a l'inconvénient d'être aussi plus rigide et de ne pas tolérer des courbes de petit rayon. Le fonctionnement de l'ensemble reste le même.In another embodiment according to FIG. 10, instead of making the vehicle with spherical connections and chassis articulated with respect to each other, it is possible to overcome the various body sections by a profile 38 of a single piece connecting all the thrust bearings 39 which are attached to the fork 8. This connection is less flexible than the previous one, but considering the long lengths present and the small curvatures of the track, the profile 38 is chosen so that 'they are flexible enough to deform by bending and adapt to the track whatever route is drawn. This device has the advantage of being simpler (and therefore less expensive) than the previous one, but has the disadvantage of also being more rigid and of not tolerating curves of small radius. The functioning of the whole remains the same.

La figure 11 représente un train de roues équipées de galets supplémentaires 41 placés aux deux extrémités du balancier 12 et qui prennent appui contre une des faces latérales de la voie de roulement. Ces galets agissent sur le train de roues et le dirigent continuellement de telle façon que la direction de roulement du train de roues corresponde en permanence à celle de la voie. Dans cette figure, deux galets ont été disposés à l'avant et à l'arrière, mais il va de soi que le train de roues pourrait en comprendre deux disposés à l'avant, ou 4 galets mis à chaque extrémité gauche et droite du train de roues. Ces galets de guidage 41 sont portés par des bras 42 solidaires du balancier 12.FIG. 11 represents a train of wheels fitted with additional rollers 41 placed at the two ends of the balance 12 and which bear against one of the lateral faces of the track. These rollers act on the wheel train and continuously steer it in such a way that the running direction of the wheel train constantly matches that of the track. In this figure, two rollers have been arranged at the front and at the rear, but it goes without saying that the wheel set could include two arranged at the front, or 4 rollers placed at each left and right end of the wheel train. These guide rollers 41 are carried by arms 42 integral with the balance 12.

Dans le cas de cette figure, la bielle auxiliaire 36 assurant la verticali- sation de la fourche 8 est placée au-dessous de la liaison sphérique 20, alors qu'elle était disposée au-dessus dans le cas de la figure 9.In the case of this figure, the auxiliary connecting rod 36 ensuring the verticalization of the fork 8 is placed below the spherical link 20, while it was arranged above in the case of FIG. 9.

Enfin, cette figure mentionne la présence d'un dispositif d'attelage 40 permettant d'atteler deux ou plusieurs véhicules l'un à l'autre pour constituer un convoi plus important.Finally, this figure mentions the presence of a coupling device 40 making it possible to couple two or more vehicles to one another to constitute a larger convoy.

La figure 12 est une vue en plan, vue depuis dessus, d'un train de quatre roues motorisées selon l'invention. Ce dessin représente deux solutions différentes de cette construction. A droite de la figure, le train comporte deux moteurs d'entrafnement 43 portés par le balancier d'équilibrage 12 et comprenant chacune une poulie motrice 44. Les roues 11 comportent elles une poulie réceptrice 45. Ces deux paires de poulies sont reliées par deux jeux de courroies trapézordales 46. A gauche de la figure, un moteur d'entraînement 43 entraîne un arbre, non-représenté sur la figure, un système d'engrenages comportant un différentiel qui entraîne en rotation deux poulies 44 alignées avec les poulies réceptrices 45 solidaires des roues 11. Comme précédemment, ces paires de poulies 44 et 45 sont reliées par deux jeux de courroies trapézoïdales 46.Figure 12 is a plan view, seen from above, of a train of four motorized wheels according to the invention. This drawing represents two different solutions of this construction. To the right of the figure, the train comprises two drive motors 43 carried by the balancing balance 12 and each comprising a driving pulley 44. The wheels 11 have a receiving pulley 45. These two pairs of pulleys are connected by two sets of V-belts 46. On the left of the figure, a drive motor 43 drives a shaft, not shown in the figure, a gear system comprising a differential which rotates two pulleys 44 aligned with the receiving pulleys 45 integral with the wheels 11. As before, these pairs of pulleys 44 and 45 are connected by two sets of trapezoidal belts 46.

Donc, dans le cas de cette figure, chaque roue porteuse est motrice. Cette construction a l'avantage de rendre toutes les roues motrices indépendantes les unes des autres en rotation, leur couplage n'étant réalisé que par des liaisons électriques, dans le cas de la solution dessinée à droite de la figure, ou comportant un différentiel dans l'autre cas. Les galets de guidage 41 ont également été représentés sur cette figure. Enfin, l'axe de chaque roue 11 se prolonge vers l'extérieur et comporte un disque 47 sur lequel agissent des freins non-représentés sur la figure. Ces freins sont utilisés pour assurer l'arrêt du véhicule en station et pour sa sécurité.So, in the case of this figure, each carrier wheel is driving. This construction has the advantage of making all the driving wheels independent of each other in rotation, their coupling being carried out only by electrical connections, in the case of the solution drawn on the right of the figure, or comprising a differential in the other case. The guide rollers 41 have also been shown in this figure. Finally, the axis of each wheel 11 extends outward and includes a disc 47 on which act brakes not shown in the figure. These brakes are used to stop the vehicle in the station and for its safety.

Les différentes solutions représentées dans les figures et décrites dans le texte ne comportent aucune suspension élastique, ni amortisseur de vibrations destinés à augmenter le confort du véhicule. Il va de soi qu'il est possible de prévoir de tels dispositifs par exemple entre les roues 11 et les balanciers 12 et/ou 21, entre la fourche 8 et la liaison sphérique 20 entre les châssis 33 et 38 et les véhicules.The different solutions shown in the figures and described in the text do not include any elastic suspension or vibration damper intended to increase the comfort of the vehicle. It goes without saying that it is possible to provide such devices for example between the wheels 11 and the pendulums 12 and / or 21, between the fork 8 and the spherical link 20 between the chassis 33 and 38 and the vehicles.

La figure 12 montre une solution possible de la motorisation des roues 11, utilisant des transmissions à .courroies trapézordales. D'autres solutions auraient pu être retenues, par exemple en plaçant un moteur en bout d'arbre de quelques poulies 11, ou en utilisant des transmissions à engrenages, etc. Par ailleurs, il va de soi qu'il n'est pas nécessaire de motoriser la totalité des roues du véhicule.FIG. 12 shows a possible solution of the motorization of the wheels 11, using transmissions with. Trapezoidal belts. Other solutions could have been adopted, for example by placing a motor at the end of the shaft of a few pulleys 11, or by using gear transmissions, etc. Furthermore, it goes without saying that it is not necessary to motorize all of the wheels of the vehicle.

De même dans les figures et la description, il n'a été fait allusion qu'à la présence de soufflets liant deux tronçons consécutifs de caisse. Il est évident que la caisse comprend un plancher de circulation .des passagers. Au droit de la liaison de deux tronçons de caisse, des éléments articulés de ce plancher se superposent, glissent l'un sur l'autre et établissent une liaison continue malgré les courbes de la voie et de ses changements de pente.Similarly in the figures and the description, reference has only been made to the presence of bellows connecting two consecutive sections of the body. It is obvious that the body includes a floor for circulation of passengers. To the right of the connection of two body sections, articulated elements of this floor are superimposed, slide one on the other and establish a continuous connection despite the curves of the track and its changes in slope.

Dans la description, il a été admis que la voie était dans un même plan, et de plus horizontal. Mais en fait, des changements de direction et de pente peuvent se présenter, car les divers tronçons du véhicule sont articulés horizontalement et peuvent fléchir verticalement les uns par rapport aux autres.In the description, it was assumed that the track was in the same plane, and moreover horizontal. But in fact, changes in direction and slope can occur, because the various sections of the vehicle are articulated horizontally and can flex vertically with respect to each other.

L'énergie nécessaire à la motorisation du véhicule est, dans le cas présent, électrique. L'installation comporte, non-représentée aux dessins, une suspension caténaire amenant l'énergie par l'intermédiaire de trolleys. D'autres modes pourraient être envisagés, par exemple le véhicule embarquant une génératrice électrique entrafnée par un moteur à explosion, à combustion interne, ou encore par une turbine.The energy required to power the vehicle is, in this case, electric. The installation includes, not shown in the drawings, a catenary suspension supplying energy via trolleys. Other modes could be envisaged, for example the vehicle carrying an electric generator driven by an internal combustion engine, or by a turbine.
