L'invention est relative à un équipement de roulement pour véhicule monorail en porte à faux.The invention relates to rolling equipment for monorail vehicle overhang.
Un tel véhicule est destiné aux transports urbains de passagers, dans le cadre de réseaux pour villes de petite ou moyenne importance dits en marguerite. Ce type de réseau comprend des lignes courtes, s'étendant sur quelques kilimètres, et dont les lignes en sens unique forment des boucles se tangeantant les unes aux autres et comportant dans ces zones de tangence des stations de raccordement permettant un transfert quai à quai des usagers.Such a vehicle is intended for urban passenger transport, in the context of networks for small or medium-sized cities called daisy. This type of network comprises short lines, extending over a few kilimeters, and whose one-way lines form loops tangent to each other and having in these zones of tangency connecting stations allowing a quay-to-quay transfer of users.
Il peut aussi être utilisé en rabattage sur des réseaux de transport urbains plus lourds, tels que métro, tramway ou bus circulant en site réservé ou en site intégré.It can also be used for hoists on heavier urban transport networks, such as metro, tramway or bus operating on a reserved site or an integrated site.
Un tel réseau est destiné :Such a network is intended:
- soit à des petites et moyennes agglomérations ;- to small and medium-sized towns;
- soit pour rabattre les usagers sur des moyens de transport lourds, de type métro, V. A. L , Traintram ; en remplacement de véhicules tels que bus ou, éventuelement, Tramway, plus coûteux en énergie, plus encombrants ou plus pollants.- or to reduce the number of users on heavy means of transport, such as metro, V. A. L, Traintram; to replace vehicles such as buses or, possibly, trams, which are more expensive, more bulky or more polluting.
Un véhicule pour réseau en marguerite est décrit dans la demande internationale WO97/27095 au nom de l'inventeur. est contituée par une pluralité de boucles qui, à sens unique de circulation des cabines, présentent entre elles au moins un point de tangence permettant de constituer une station de correspondance rapide de type « quai à quai ». Sur chaque boucle circulent avec une fréquence élevée des véhicules motorisés ayant une capacité de l'ordre de 10 à 20 personnes. Ce réseau ne nécessite qu'une infrastructure légère en site propre, par exemple composée de poteaux portant un rail continu sur lequel circulent, en surélévation du sol, des cabines motorisées.A daisy network vehicle is described in international application WO97 / 27095 in the name of the inventor. is constituted by a plurality of loops which, in a single direction of circulation of the cabins, have between them at least one point of tangency for constituting a quick dock-type correspondence station "quai à quai". On each loop circulate with a high frequency of motorized vehicles having a capacity of the order of 10 to 20 people. This network requires only a light infrastructure clean site, for example consisting of posts carrying a continuous rail on which move, elevated soil, motorized cabins.
L'invention concerne les réseaux dont les véhicules sont en porte à faux d'un coté du rail et comprenant, comme décrit dans les documents WO97/27 095 et US 4 690 064, deux chariots porteurs espacés longitudinalement et coopérant avec un rail profilé.The invention relates to networks whose vehicles are cantilevered on one side of the rail and comprising, as described in documents WO97 / 27,095 and US 4,690,064, two carrier trolleys longitudinally spaced and cooperating with a profiled rail.
Elle concerne plus particulièrement une cabine dans laquelle, comme dans le document US 4 690 064, chaque chariot comprend : des moyens de roulement supérieurs, formé par un train de roues libres en rotation autour d'un axe horizontal, roulant sur le plan supérieur horizontal du rail et reprenant la composante verticale des forces, des moyens de roulement intermédiaires, avec des roues motrices, disposées latéralement au rail contre lequel elles s'appuient en reprenant une partie de la composante transversale des forces tendant à faire basculer la cabine en porte à faux, et des moyens de roulement inférieurs formés par des roues libres en rotation et également disposées latéralement au rail contre lequel elles roulent en reprenant la composante transversale de réaction aux forces de basculement.It relates more particularly to a cabin in which, as in document US 4,690,064, each carriage comprises: upper bearing means, formed by a set of freewheels rotating about a horizontal axis, rolling on the horizontal upper plane of the rail and taking up the vertical component of the forces, intermediate bearing means, with driving wheels arranged laterally to the rail against which they rest by taking up part of the transverse component of the forces tending to tilt the cabin overhang, and lower rolling means formed by freewheels in rotation and also disposed laterally to the rail against which they roll by taking up the transverse component of reaction to the tilting forces.
Dans chaque chariot, les différentes roues de chaque moyens de roulement sont espacées longitudinalement et sont disposées de part et d'autre du plan médian transversal du chariot, c'est-à-dire sont réparties en avant et en arrière de ce plan transversal. En raison de cette disposition linéaire des roues, bien visible à la figure 2 du document US 4 690 064, quand la cabine circule sur une courbe du rail, que celle ci soit convexe ou concave, certaines de ses roues contribuant à l'équilibrage de la cabine sont plaquées latéralement contre le rail avec un effort plus grand, alors que d'autres roues sont soumises à un effort moindre et voir nul. Il en résulte que, malgré la présence éventuelle de moyens compensateurs amortissants les variations de pression d'application, les frottements roue/rail sont accrus, génèrent des bruits et des usures des roues et du rail et consoment inutilement de l'énergie. En outre, la variation des contacts des roues avec le rail, engendre des secousses qui sont sources d'inconfort pour les passagers.In each carriage, the different wheels of each rolling means are spaced longitudinally and are disposed on either side of the transverse median plane of the carriage, that is to say are distributed in front and rear of the transverse plane. Due to this linear arrangement of the wheels, clearly visible in Figure 2 of US 4,690,064, when the cab is traveling on a curve of the rail, whether it is convex or concave, some of its wheels contributing to the balancing of the cab are plated laterally against the rail with greater effort, while other wheels are subjected to less effort and see no one. As a result, despite the possible presence of damping compensating means the application pressure variations, wheel / rail friction is increased, generate noise and wear of wheels and rail and consume unnecessarily energy. In addition, the variation of the wheel contacts with the rail, generates jolts which are sources of discomfort for the passengers.
Le présente invention à pour objet de remédier à ces inconvénients en fournissant un équipement de roulement procurant un équilibre stable de la cabine, même en courbe, et une adhérence régulière des roues avec le rail, tout en réduisant les glissements générateurs de bruits et d'usure des roues et du rail.The object of the present invention is to overcome these drawbacks by providing rolling equipment which provides a stable equilibrium of the car, even when in a curve, and a regular adhesion of the wheels with the rail, while reducing the slips generating noise and wheel and rail wear.
A cet effet, dans l'équipement selon l'invention, le rail présente en section transversale la forme générale d'un Z, dont la partie supérieure et l'embase sont horizontales et sont reliées par une âme inclinée avec lesquelles elles forment, du coté opposé à la cabine, une cavité supérieure et, du coté de la cabine, une cavité inférieure, tandis que dans chaque chariot :For this purpose, in the equipment according to the invention, the rail has in cross section the general shape of a Z, the upper portion and the base are horizontal and are connected by an inclined core with which they form, on the opposite side to the cabin, an upper cavity and, on the side of the cabin, a lower cavity, while in each carriage:
- les moyens de roulement supérieurs comprennent une seule roue porteuse,the upper bearing means comprise a single carrier wheel,
- les moyens intermédiaires comprennent une seule roue motrice et de maintien, roulant dans le fond de la cavité supérieure du rail en Z, la dite roue étant portée par un arbre dont l'axe vertical est incliné vers le bas par rappor ta l'horizontale, - et les moyens inférieurs de roulement comprennent une seule roue inférieure roulant dans la cavité inférieure du rail en Z, la dite roue étant libre en rotation et montée sur un arbre incliné vers la haut par rapport à l'horizontale, ces roues étant disposées de façon que leurs axes de rotation soient dans le même plan vertical P1 , transversal au rail, et que leurs points médians de tangence A, B.et C avec les faces de roulement du rail soient disposés dans le plan vertical médian longitudinal P2 du rail, plan contenant la roulante du chariot.the intermediate means comprise a single drive wheel and holding wheel, rolling in the bottom of the upper cavity of the Z-shaped rail, said wheel being carried by a shaft whose vertical axis is inclined downwardly relative to the horizontal and the lower rolling means comprise a single lower wheel rolling in the lower cavity of the Z-rail, said wheel being free to rotate and mounted on a shaft inclined upwards with respect to the horizontal, these wheels being arranged so that their axes of rotation are in the same vertical plane P1, transverse to the rail, and that their median points of tangency A, B. and C with the rolling faces of the rail are arranged in the longitudinal median longitudinal plane P2 of the rail , plane containing the rolling cart.
Grâce à cet aménagement, les divers points de contact de chaque chariot avec le rail sont répartis sur un même axe vertical, de sorte que toute modification de l'angulation de la cabine par rapport à chacun de ces chariots, de même que toute inscription de la cabine dans une courbe du rail, sont sans aucune conséquence sur l'effort de plaquage des roues sur le rail, qui est ainsi pincé entre les roues. Il en résulte que sont constantes la qualité de l'adhérence des roues avec le rail, le frottement et les bruits qui en résultent. Une telle cabine est ainsi plus stable, plus confortable tout en consommant moins d'énergie pour son déplacement.Thanks to this arrangement, the various points of contact of each carriage with the rail are distributed on the same vertical axis, so that any modification of the angulation of the cabin with respect to each of these carriages, as well as any inscription of the cabin in a curve of the rail, are without any consequence on the force of plating of the wheels on the rail, which is thus pinched between the wheels. As a result, the quality of the grip of the wheels with the rail, the friction and the resulting noises are constant. Such a cabin is thus more stable, more comfortable while consuming less energy for its movement.
La constance de la pression des roues sur le rail améliore considérablement le confort des passagers en supprimant tous les chocs et mouvements de la cabine consécutifs aux variations de trajectoire de la cabine.Consistent wheel pressure on the rail greatly enhances passenger comfort by eliminating all shocks and cabin movements resulting from cabin trajectory changes.
Dans une forme d'exécution, chacune des roues, respectivement intermédiaire et inférieure, prend appui sur une face de roulement ménagée dans le fond de la cavité correspondante du rail et cette face forme, par rapport au plan médian vertical et longitudinal P2 du rail, un angle b de valeur égale à celle de l'angle a d'inclinaison des arbres de ces roues par rapport au même plan médian P2.In one embodiment, each of the wheels, respectively intermediate and lower, is supported on a rolling face formed in the bottom of the corresponding cavity of the rail and this face forms, relative to the vertical and longitudinal median plane P2 of the rail, an angle b of value equal to that of the angle of inclination of the shafts of these wheels with respect to the same median plane P2.
Les chemins de roulement sont ainsi parfaitement définis et plans, ce qui garantit l'alignement vertical des points de tangence A, B et C des roues avec le rail et réduit les glissements en courbe aux parties de chaque roue disposées de part et d'autre de ces points de tangence.The raceways are thus perfectly defined and flat, which guarantees the vertical alignment of the points of tangency A, B and C of the wheels with the rail and reduces the curved sliding to the parts of each wheel arranged on either side. of these points of tangency.
Avantageusement, chacune des faces de roulement pour les roues, respectivement, intermédiaire et inférieure, est bordée par des faces de dégagement allant en s'écartant et améliorant le positionnement des roues contre le rail.Advantageously, each of the rolling faces for the wheels, respectively intermediate and inferior, is bordered by release faces going away and improving the positioning of the wheels against the rail.
Dans une forme d'exécution préférée, chacun des arbres portant, respectivement, soit la roue intermédiaire, soit la roue inférieure, est lié au châssis du chariot avec interposition de moyens de réglage de sa position transversale par rapport au châssis, pour adapter aux besoins de l'adhérence la pression d'application de la roue sur le rail.In a preferred embodiment, each shaft carrying, respectively, the intermediate wheel or the lower wheel, is connected to the chassis of the carriage with the interposition of means for adjusting its transverse position relative to the chassis, to adapt to the needs adhesion the application pressure of the wheel on the rail.
Il est ainsi possible, de régler la pression d'application de chacune de ces roues sur le rail, soit pour l'adapter à une modification de la forme de la boucle de son réseau, soit pour compenser les usures des roues et les déréglages des moyens de placage. D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé montrant une forme d'exécution de cet équipement.It is thus possible to adjust the application pressure of each of these wheels on the rail, either to adapt it to a modification of the shape of the loop of its network, or to compensate for wheel wear and misalignment of the wheels. plating means. Other features and advantages will become apparent from the description which follows with reference to the attached schematic drawing showing an embodiment of this equipment.

L'angle aigu formé entre la paroi supérieure 22 et l'âme 24 délimite une cavité supérieure 25, tandis que celui formé entre cette âme 24 et l'embase 23 délimite une cavité inférieure 26, disposée de l'autre coté de l'âme. Le fond de chacune de ces cavités est constitué par une face plane de roulement, respectivement 27 et 28, qui, par rapport au plan médian longitudinal P2, est inclinée d'un angle b dont la valeur angulaire est égale à celle de l'angle a d'inclinaison des arbres 16 et 18. Les faces de roulement 27 et 28 sont bordées par des faces latérales 29 allant en s'évasant depuis le fond et dégageant l'accès aux faces de roulement.It is specified that the shaft 16 goes from the frame downwards while the shaft 18 goes from the chassis upwards. Each of the shafts 16 and 18 and slidably mounted on the frame member which carries it and with the interposition of means 20 which, shown schematically with Parbre18 in Figure 3, to adjust the force with which the wheel 12 is plated on the rail 3. As shown in Figure 4, the rail 3 has in cross section the general shape of the letter Z, that is to say is composed of an upper horizontal wall 22, a lower horizontal base 23 and an inclined soul 24 connecting them. The acute angle formed between the upper wall 22 and the core 24 delimits an upper cavity 25, while the one formed between this core 24 and the base 23 defines a lower cavity 26, disposed on the other side of the core. . The bottom of each of these cavities is constituted by a plane rolling face, respectively 27 and 28, which, with respect to the longitudinal median plane P2, is inclined by an angle b whose angular value is equal to that of the angle The bearing faces 27 and 28 are bordered by lateral faces 29 flaring from the bottom and giving access to the rolling faces.
La cavité inférieure 26 qui peut retenir les eaux des intempéries communique avec l'extérieur par des canaux de vidange 30.The lower cavity 26 which can retain the water from the weather communicates with the outside by drain channels 30.
Dans la forme d'exécution représentée, l'embase 23 du rail se prolonge en 23a, en avant du pied de l'âme 24, pour augmenter la surface d'appui du rail sur le sommet du poteau 1 , mais la section en Z peut prendre toute autre configuration.In the embodiment shown, the base 23 of the rail extends at 23a, in front of the base of the core 24, to increase the support surface of the rail on the top of the post 1, but the Z-section can take any other configuration.
De façon connue, le rail 3 porte aussi les moyens d'alimentation électrique des moteurs 17 des véhicules du réseau. Dans la forme d'exécution représentée aux figures 4 et 5, ces moyens sont constitués par au moins une barre 32 en matériau conducteur de l'électricité qui est disposée dans la paroi supérieure 22 du rail et dont la face inférieure, non isolée, est en saillie de la face inférieure de la dite paroi, pour pouvoir coopérer avec des frotteurs 33 portés par au moins l'un des châssis équipant un véhicule. Si le réseau est télécommandé depuis un poste de commande fixe, commun à tous les véhicules, la liaison entre le poste et chaque véhicule peut auusi être assurée par d'autres conducteurs électriques disposés, comme celui 32, sous la paroi 22 et coopérant avec des frotteurs ou autres moyens de captage de signaux portés par chaque véhicule. Enfin, la liaison entre la cabine 2 et et les chariots 4 est assurée avec interposition de moyens de suspension 34 et 35 à faible débattement.In known manner, the rail 3 also carries the power supply means of the motors 17 of the network vehicles. In the embodiment shown in FIGS. 4 and 5, these means consist of at least one bar 32 made of electrically conductive material which is disposed in the upper wall 22 of the rail and whose underside, which is not insulated, is protruding from the underside of said wall, to cooperate with the shoes 33 carried by at least one of the chassis fitted to a vehicle. If the network is remotely controlled from a fixed control station, common to all vehicles, the connection between the station and each vehicle can also be ensured by other electrical conductors arranged, like that 32, under the wall 22 and cooperating with wipers or other means of picking up signals carried by each vehicle. Finally, the connection between the car 2 and the carriages 4 is provided with the interposition of suspension means 34 and 35 low clearance.
Quand le véhicule est positionné sur le rail 3, comme montré à la figure 5, dans chaque chariot 4, la roue 10 repose sur la face supérieure horizontale 21 du rail 3 en reprenant l'essentiel de la charge du véhicule, tandis que la roue motrice 11 prend appui contre la face de roulement 27 de la cavité supériere 25 et que la roue 12 prend appui contre la face de roulement 28 de la cavité inférieure 26, disposée de l'autre coté de l'âme 24. Ces deux dernières roues reportent sur le rail les composantes transversales des forces tendant à faire basculer la cabine 2 du coté du dos du profil en Z et, grâce à leurs moyens 20 de réglage de l'effort d'application contre le rail, sont en contact permanent avec celui-ci. Il en résulte que leurs bandes de roulement ont une adhérence régulière avec les faces 27 et 28 contre lesquelles elles roulent sans glissement et que les pertes d'énergie sont réduites. Quand le véhicule est en courbe, et grâce aux faits que chacun des moyens de roulement, supérieurs, intermédiaires et inférieurs, ne comporte qu'une roue et que toutes les roues sont disposées de manière que leurs points médians A, B et C de tangence avec les faces de roulement du rail soient alignés verticalement sur la roulante du chariot, les roues restent en contact avec le rail et ne subissent aucune perte d'adhérence et aucun glissement, quelle que soit la vitesse de déplacement du véhicule. Ce contact permanent des moyens de roulement avec le rail et le serrage de l'âme 24 du rail par les roues 11 et 12, supprime les chocs et vibrations, améliore considérablement le confort des passagers et rend la cabine insensible aux effets de vents latéraux forts.When the vehicle is positioned on the rail 3, as shown in FIG. 5, in each carriage 4, the wheel 10 rests on the horizontal upper face 21 of the rail 3, taking up most of the load of the vehicle, while the wheel motor 11 bears against the bearing face 27 of the upper cavity 25 and that the wheel 12 bears against the rolling face 28 of the lower cavity 26, disposed on the other side of the core 24. The latter two wheels report on the rail the transverse components of the forces tending to tilt the cabin 2 on the back side of the Z-profile and, thanks to their means 20 for adjusting the application force against the rail, are in constant contact with the -this. As a result, their treads have a regular adhesion with the faces 27 and 28 against which they roll without sliding and the energy losses are reduced. When the vehicle is in a curve, and thanks to the facts that each of the rolling means, upper, intermediate and lower, has only one wheel and all the wheels are arranged so that their tangential points A, B and C of tangency with the rolling faces of the rail are aligned vertically on the wheel of the carriage, the wheels remain in contact with the rail and undergo no loss of adhesion and no slippage, regardless of the speed of movement of the vehicle. This permanent contact of the rolling means with the rail and the tightening of the web 24 of the rail by the wheels 11 and 12, eliminates shocks and vibrations, greatly improves the comfort of the passengers and makes the cabin insensitive to the effects of strong side winds .
Ces avantages sont d'autant plus importants que la longueur L de la cabine est faible, et par exemple comprise entre 4 à 8 mètres, et que chacun des chariots 4 est disposé à une distance D de l'extrémité de la cabine qui lui est la plus proche, distance ayant une valeur égale à 25% de L. II apparaît donc que l'équipement selon l'invention permet d'utiliser dans des réseaux de transports légers des véhicules de type « assis sur le rail », sans qu'il soit nécessaire d'avoir recours à des systèmes délicats et onéreux de maintien en position verticale du véhicule sur le rail, en particulier dans les courbes, et sans utiliser, comme dans les véhicules suspendus, des infrastructures importantes et onéreuses.These advantages are all the more important that the length L of the cabin is small, for example between 4 to 8 meters, and each of the carriages 4 is disposed at a distance D from the end of the cabin which is the closest, a distance having a value equal to 25% of L. It therefore appears that the equipment according to the invention makes it possible to use in vehicles of the type "sitting on the rail" in light transport networks, without which it is necessary to resort to delicate and expensive systems for maintaining the vehicle in a vertical position on the rail, in particular in the curves, and without using, as in the suspended vehicles, important and expensive infrastructures.
Par sécurité, chacun des moteurs électriques 17 entraînant l'une des deux roues motrices intermédiaires 11 d'une même cabine 2 est un moteur frein dont la commande d'alimentation est distincte de celle concernant l'autre moteur, mais est sous le contrôle d'une unité commune. Ainsi en cas de panne d'un moteur, l'autre moteur peut assurer le retour du véhicule.For safety, each of the electric motors 17 driving one of the two intermediate drive wheels 11 of the same cabin 2 is a brake motor whose control of supply is distinct from that concerning the other engine, but is under the control of a common unit. Thus in case of failure of one engine, the other engine can ensure the return of the vehicle.
Enfin, la forme particulière en Z du rail, permet d'assurer aisément son nettoyage, avec un véhicule spécifique, même en période fonctionnement du réseau. Par ailleurs, le positionnement de la roue motrice 11 dans la cavité supérieure 25 la mieux protégée du rail, garantit l'adhérence et l'absence de glissement du couple moteur, quelles que soient les intempéries. Finally, the particular Z shape of the rail makes it easy to clean with a specific vehicle, even during network operation. Furthermore, the positioning of the drive wheel 11 in the upper cavity 25 the best protected rail, ensures adhesion and no slip of the engine torque, whatever the weather.
