Description

DISPOSITIF DE GUIDAGE ET DE CAPTAGE D'ENERGIE ELECTRIQUE AU SOL POUR VEHICULE, ET VEHICULE DE TRANSPORT URBAIN EQUIPE D'UN TEL DISPOSITIFDEVICE FOR GUIDING AND CAPTURING ELECTRIC GROUND ENERGY FOR VEHICLE, AND URBAN TRANSPORT VEHICLE EQUIPPED WITH SUCH A DEVICE
La présente invention a pour objet un dispositif de captage d'énergie électrique au sol et de guidage pour véhicule, ainsi qu'un véhicule de transport urbain équipé d'un tel dispositif.The present invention relates to a device for collecting electrical energy on the ground and vehicle guidance, and an urban transport vehicle equipped with such a device.
La présente invention concerne notamment le domaine du transport urbain, automatique ou non, de personnes.The present invention relates in particular to the field of urban transport, automatic or not, people.
Dans ce domaine du transport urbain de personnes on connait de nombreuses techniques qui ont été mises en œuvre avec plus ou moins de succès . Ces techniques diffèrent soit par le mode de propulsion, et/ou soit par le mode de guidage, et/ou soit par le mode de captage de l ' énergie électrique .In this area of urban transport of people we know many techniques that have been implemented with varying degrees of success. These techniques differ either by the mode of propulsion, and / or by the guide mode, and / or by the mode of capture of the electrical energy.
La propulsion est généralement électrique, tandis que le guidage est réalisé au travers d'un rail ou de plusieurs.The propulsion is generally electric, while the guidance is achieved through a rail or several.
En ce qui concerne le mode de captage de l'énergie électrique, la technique la plus fréquemment utilisée consiste à disposer sur le trajet du véhicule des câbles aériens auxquels se connecte ledit véhicule . L ' inconvénient de cette technique est essentiellement esthétique, et pour y pallier il a été proposé 1 ' alternative de l ' alimentation souterraine .Regarding the mode of capture of electrical energy, the most frequently used technique is to have in the path of the vehicle overhead cables which connects said vehicle. The disadvantage of this technique is essentially aesthetic, and in order to overcome it, the alternative of the underground feed has been proposed.
Dans le domaine de l ' alimentation souterraine on connait de nombreux systèmes, lesquels doivent tous répondre au même impératif, permettre la fourniture d'énergie au véhicule, sans que cela présente un risque pour les personnes . On peut en effet comprendre que l ' alimentation étant réalisée au travers de conducteurs nus sous tension, ceux-ci ne doivent pas être accessibles aux personnes. La technique la plus courante est par exemple celle décrite dans les documents JP 62181929 et EP 1 694 525, où les conducteurs nus sous tension sont disposés dans un caniveau pratiqué dans la chaussée et fermé par un platelage, tandis qu'un moyen capteur, lié au véhicule, vient au contact desdits conducteurs en passant par une fente pratiquée dans ledit platelage. Un tel système nécessite, afin que le capteur demeure au contact des conducteurs, que le guidage du véhicule soit réalisé de manière précise par rapport à ceux-ci et donc audit caniveau, en sorte qu'il est indispensable de recourir à l'utilisation d'au moins un rail de guidage .In the field of underground power, many systems are known, all of which must meet the same requirements, allow the supply of energy to the vehicle, without any risk to people. It can indeed be understood that the power supply being performed through bare conductors under tension, they must not be accessible to people. The most common technique is, for example, that described in documents JP 62181929 and EP 1 694 525, in which the bare conductors under tension are arranged in a gutter made in the carriageway and closed by a decking, while a sensor means, linked to the vehicle, comes into contact with said conductors through a slot in said decking. Such a system requires, so that the sensor remains in contact with the conductors, that the guidance of the vehicle is carried out accurately with respect to them and therefore to said gutter, so that it is essential to resort to the use of at least one guide rail.
Dans le document JP 62181929, le guidage est réalisé par l'intermédiaire de rails disposés de part et d'autre du platelage et dans lesquels roule le véhicule à déplacer, tandis que dans le document EP 1 694 525 il est réalisé au niveau de la fente pratiquée dans le platelage.In the document JP 62181929, the guiding is carried out by means of rails arranged on either side of the decking and in which the vehicle to be moved rolls, whereas in the document EP 1 694 525 it is realized at the level of the slit practiced in the decking.
Or, le guidage par rail présente de nombreux inconvénients en zone urbaine, parce que les virages y sont serrés, notamment de bruit et d'usure prématurée des rails et/ou des roues ou galets du fait de la grande pression exercée par le poids du véhicule.However, the guide rail has many disadvantages in urban areas, because the turns are tight, including noise and premature wear of the rails and / or wheels or rollers due to the great pressure exerted by the weight of vehicle.
Pour pallier cet inconvénient il est indispensable de que certains passages soient réalisés à très faible vitesse, au détriment des souhaits de l'usager.To overcome this drawback it is essential that some passages are made at very low speed, to the detriment of the wishes of the user.
On connaît aussi par les documents FR 2 613 305, DE 76 067 et, des dispositifs de guidage et de motorisation enterrés, comprenant également un caniveau dans lequel peut se déplacer tracteur, qui tire le véhicule qui est guidé en surface.Also known from documents FR 2 613 305, DE 76 067 and underground guiding and motorization devices, also comprising a trench in which can move tractor, which pulls the vehicle which is guided on the surface.
Dans le document FR 2 613 305 le tracteur roule sur les parois verticales latérales du caniveau, et est mû par une source d'énergie mécanique produite à l'intérieur dudit caniveau. Un tel dispositif présente des inconvénients liés à l ' usure des éléments qui le composent, et de sécurité puisque le moyen moteur étant déporté dans le caniveau, il y a peu de possibilité d'intervention directe en cas de dysfonctionnement. De plus, là encore le guidage par rail du véhicule en surface présente des inconvénients de bruit et d'usure.In the document FR 2 613 305 the tractor rolls on the vertical side walls of the gutter, and is moved by a source of mechanical energy produced inside said gutter. Such a device has disadvantages related to the wear of the elements that make it up, and of safety since the means motor being deported in the gutter, there is little possibility of direct intervention in case of malfunction. In addition, here again the rail guidance of the vehicle on the surface has drawbacks of noise and wear.
Le document DE 76 067 décrit également un tracteur qui roule dans une infrastructure et qui capte l'énergie nécessaire à son avancement sur des conducteurs nus disposés le long du plafond de ladite infrastructure , tandis que le véhicule de surface roule sur des rails, en présentant les mêmes inconvénients précités .The document DE 76 067 also describes a tractor which rolls in an infrastructure and which captures the energy necessary for its advancement on bare conductors arranged along the ceiling of said infrastructure, while the surface vehicle rolls on rails, presenting the same disadvantages mentioned above.
Le véhicule objet du document DE 36 01 128 présente la particularité d'être équipé de deux motorisations, d'une part il comporte un moteur à combustion, et d'autre part il est relié à un tracteur souterrain fonctionnant à l'énergie électrique, destiné à prendre le relais du moteur à combustion lors de passage dans des lieux qui nécessitent du calme et/ou dans lesquels il ne faut pas émettre de gaz d'échappement. Le véhicule est guidé en surface par l ' intermédiaire de glissières latérales , contre lesquelles viennent rouler des roues latérales d'axes verticaux. Si ce véhicule ne présente pas les inconvénients du guidage par rail , il demeure encombrant puisqu'il nécessite que lui soit réservé un couloir de circulation, bordé par les glissières.The vehicle of document DE 36 01 128 has the particularity of being equipped with two engines, on the one hand it comprises a combustion engine, and on the other hand it is connected to an underground tractor operating with electrical energy, intended to take over the combustion engine when passing in places that require calm and / or in which no exhaust gas must be emitted. The vehicle is guided on the surface by means of lateral slides, against which side wheels of vertical axes are rolled. If this vehicle does not have the drawbacks of rail guidance, it remains cumbersome since it requires that it be reserved a traffic corridor, bordered by the slides.
Les dispositifs de captage et de guidage de véhicule existants présentent tous des inconvénients , principalement au niveau des moyens de guidage du véhicule terrestre . La présente invention a pour but de remédier à ces divers inconvénients en proposant un dispositif de captage d'énergie électrique au sol et de guidage pour véhicule, permettant d'alimenter en énergie électrique un véhicule au travers de conducteurs nus, sans que ceux-ci soient accessibles aux personnes, et permettant de s'affranchir des superstructures, en ne nécessitant que des infrastructures. Le dispositif de captage d'énergie électrique au sol et de guidage pour véhicule selon l'invention comprend des conducteurs nus sous tension disposés dans un caniveau pratiqué dans la chaussée et fermé par un platelage, tandis que d'une part un moyen capteur vient au contact desdits conducteurs en passant par une fente pratiquée dans ledit platelage, et que d'autre part ledit véhicule comporte un moteur électrique alimenté au travers dudit moyen capteur, et qui permet de mouvoir directement ou indirectement ledit véhicule , et il se caractérise en ce que lesdits conducteurs consistent en des rails et que ledit moyen capteur consiste en un chariot apte à rouler sur lesdits rails et à être guidé par ceux-ci; et en ce que ledit chariot est relié mécaniquement audit véhicule au travers d'un bras articulé, et qu'il est muni de moyens de mesures prévus aptes à mesurer le sens et l'amplitude des déplacements dudit bras par rapport audit chariot, et à transmettre ces données aux moyens de commande des organes de direction dudit véhicule, en sorte de permettre de corriger la trajectoire dudit véhicule.Existing vehicle sensing and guidance devices all have drawbacks, mainly at the land vehicle guidance means. The aim of the present invention is to overcome these various drawbacks by proposing a device for collecting electrical energy on the ground and for guiding a vehicle, making it possible to supply electrical energy to a vehicle through bare conductors, without these are accessible to people, and to get rid of superstructures, requiring only infrastructure. The device for collecting electrical energy on the ground and for guiding a vehicle according to the invention comprises bare conductors under tension arranged in a gutter formed in the carriageway and closed by a decking, while on the one hand a sensor means comes to the contact of said conductors through a slot in said decking, and that secondly said vehicle comprises an electric motor powered through said sensor means, and which allows to move directly or indirectly said vehicle, and it is characterized in that said conductors consist of rails and said sensor means consists of a carriage adapted to roll on said rails and to be guided by them; and in that said carriage is mechanically connected to said vehicle through an articulated arm, and that it is provided with measurement means provided for measuring the direction and the amplitude of displacements of said arm with respect to said carriage, and transmit these data to the control means of the steering members of said vehicle, so as to correct the path of said vehicle.
Le guidage du véhicule est réalisé par une action sur les organes de direction de celui-ci. Lors d'un changement de direction des rails, le chariot suit ceux-ci mais pas le véhicule, ce qui génère un déplacement du bras articulé par rapport au chariot, et plus particulièrement à l'axe principal de déplacement dudit chariot. Des moyens de mesures apprécient le sens et l ' amplitude de ce déplacement du bras , et ces données sont transmises au moyen de commande des organes de direction, lesquels corrigent alors la trajectoire du véhicule.The guidance of the vehicle is achieved by an action on the steering members thereof. During a change of direction of the rails, the carriage follows them but not the vehicle, which generates a movement of the articulated arm relative to the carriage, and more particularly to the main axis of movement of said carriage. Measuring means appreciate the direction and the amplitude of this movement of the arm, and these data are transmitted to the control means of the steering members, which then correct the trajectory of the vehicle.
Selon une caractéristique additionnelle du dispositif de captage d'énergie électrique au sol et de guidage selon l'invention, le chariot comporte quatre roues , chacune à bande de roulement conique et boudin de guidage, liées deux à deux en rotation, tandis les rails sont de type champignon. Selon une autre caractéristique additionnelle du dispositif de captage d'énergie électrique au sol et de guidage selon l'invention, le chariot est disposé en avant du bras articulé et est poussé par le véhicule .According to an additional characteristic of the device for collecting electrical energy on the ground and of guiding according to the invention, the carriage comprises four wheels, each with a conical tread and a guide bead, connected two by two in rotation, while the rails are mushroom type. According to another additional characteristic of the device for collecting electrical energy on the ground and of guiding according to the invention, the carriage is placed in front of the articulated arm and is pushed by the vehicle.
Selon une autre caractéristique additionnelle du dispositif de captage d'énergie électrique au sol et de guidage selon l'invention, le chariot est disposé en arrière du bras articulé et est tiré par le véhicule.According to another additional characteristic of the device for collecting electrical energy on the ground and guiding according to the invention, the carriage is disposed behind the articulated arm and is pulled by the vehicle.
Selon une autre caractéristique additionnelle du dispositif de captage d'énergie électrique au sol et de guidage selon l'invention, le bras articulé comprend une partie sensiblement horizontale liée au véhicule par une extrémité au travers d'une première articulation de type rotule, et par son autre extrémité, au travers d'une seconde articulation de type rotule, à un mât qui s'élève du chariot et qui est engagé dans la fente longitudinale, ladite seconde articulation étant disposée au- dessus du platelage qui ferme le caniveau pratiqué dans la chaussée.According to another additional feature of the device for collecting electrical energy on the ground and guiding according to the invention, the articulated arm comprises a substantially horizontal portion connected to the vehicle at one end through a first hinge type ball joint, and by its other end, through a second hinge type ball joint, to a mast which rises from the carriage and which is engaged in the longitudinal slot, said second hinge being disposed above the decking which closes the gutter made in the floor.
Selon une autre caractéristique additionnelle du dispositif de captage d'énergie électrique au sol et de guidage selon l'invention, le bras articulé est associé à des moyens de commandes qui comprennent d'une part des moyens capteurs aptes à mesurer l ' angle formé par ledit bras avec l ' axe longitudinal du véhicule, et d'autre part des moyens d'action sur la direction dudit véhicule, aptes à permettre une correction de trajectoire proportionnelle .According to another additional characteristic of the device for collecting electrical energy on the ground and for guiding according to the invention, the articulated arm is associated with control means which comprise on the one hand sensor means able to measure the angle formed by said arm with the longitudinal axis of the vehicle, and secondly means of action on the direction of said vehicle, adapted to allow a proportional trajectory correction.
Un tel dispositif de captage d'énergie électrique au sol et de guidage trouve une application toute particulière dans le domaine du transport urbain, et permet la mise en œuvre d'un véhicule léger, automatique ou non, pour le transport de personnes . Ainsi la présente demande a également pour objet un véhicule pour le transport urbain de personnes, monté sur des roues à bandage caoutchouc ou pneus, roulant librement sur la chaussée, en enjambant le caniveau fermé par le platelage, et qui est alimenté en énergie électrique et est guidé par un dispositif de captage d'énergie électrique au sol et de guidage tel que décrit précédemment .Such a device for collecting electrical energy on the ground and guiding finds a particular application in the field of urban transport, and allows the implementation of a light vehicle, automatic or not, for the transport of people. Thus the present application also relates to a vehicle for the urban transport of people, mounted on rubber or tire wheels, rolling freely on the road, stepping over the gutter closed by the decking, and which is supplied with electrical energy and is guided by a device for collecting electrical energy on the ground and guiding as described above.
Le véhicule est, de manière préférentielle, à propulsion de type hydraulique, réalisée au travers d'une pompe hydraulique à volume variable entraînée par un moteur électrique asynchrone ou synchrone tournant à vitesse constante , et entraînant un ou plusieurs moteurs hydrauliques .The vehicle is, preferably, hydraulic type propulsion, performed through a variable volume hydraulic pump driven by an asynchronous or synchronous electric motor rotating at a constant speed, and driving one or more hydraulic motors.
Les avantages et les caractéristiques du dispositif de captage d'énergie électrique au sol et de guidage selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the device for collecting electrical energy on the ground and for guiding according to the invention will become more clearly apparent from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

En référence à la figure 1, on peut voir un dispositif 1 de captage d'énergie électrique au sol et de guidage selon l'invention, destiné à prendre place dans la chaussée C.With reference to FIG. 1, it is possible to see a device 1 for collecting electrical energy on the ground and for guiding according to the invention, intended to take place in the roadway C.
Ce dispositif 1 comprend un caniveau 2 réalisé en béton, fermé supérieurement par un platelage 3 réalisé en deux parties 30 et 31 séparées par une fente longitudinale 32, de largeur interdisant le passage d'une main et donc l'accès au caniveau 2.This device 1 comprises a gutter 2 made of concrete, closed superiorly by a decking 3 made in two parts 30 and 31 separated by a longitudinal slot 32, width prohibiting the passage of a hand and thus access to the gutter 2.
Le caniveau 2 présente inférieurement et longitudinalement un chenal 20, et latéralement à une hauteur médiane, disposés de part et d'autre du chenal 20, deux redans 21, qui supportent chacun un rail 22 , un élément 23 en matériau isolant électriquement étant intercalé entre le redan 21 et le rail 22.The channel 2 presents below and longitudinally a channel 20, and laterally at a median height, disposed on either side of the channel 20, two steps 21, each supporting a rail 22, an element 23 of electrically insulating material being interposed between the redan 21 and the rail 22.
Le caniveau 2 comporte également une saignée 24, pratiquée latéralement et longitudinalement, au-dessus du niveau des redans 21, et qui loge des conducteurs 25 haute-tension permettant l'alimentation de transformateurs, non représentés, placés cycliquement dans le caniveau 2. Ces transformateurs sont destinés à mettre sous tension les rails 22 qui constituent des conducteurs nus .The channel 2 also comprises a groove 24, made laterally and longitudinally, above the level of the steps 21, and which houses high-voltage conductors 25 for the supply of transformers, not shown, placed cyclically in the channel 2. These Transformers are intended to energize the rails 22 which constitute bare conductors.
En référence également à la figure 2 , on peut voir que sur les rails 22 est placé un chariot 4, comprenant un châssis 40 monté sur quatre roues 41.Referring also to Figure 2, it can be seen that on the rails 22 is placed a carriage 4, comprising a chassis 40 mounted on four wheels 41.
Les roues 41 sont de type chemin de fer, elles sont métalliques, et comportent une bande de roulement 42 conique et un boudin de guidage 43, tandis que les rails 22 sont de type champignon.The wheels 41 are of the railway type, they are metallic, and comprise a tread 42 conical and a guide flange 43, while the rails 22 are of the mushroom type.
En référence également à la figure 3 , on peut voir que le chariot 4 est solidarisé à un véhicule 5 roulant sur la chaussée C, au-dessus du caniveau 2, par l'intermédiaire d'un bras articulé 6 qui comprend une partie 60 sensiblement horizontale, liée au véhicule 5 par l'une de ses extrémités au travers d'une rotule 61, et liée par son autre extrémité au travers d'une rotule 62 au chariot 4, et plus exactement à l'extrémité d'un mât 44 solidaire fixement du chariot 4, et qui émerge verticalement du caniveau 2 en passant par la fente 32 du platelage 3.Referring also to Figure 3, it can be seen that the carriage 4 is secured to a vehicle 5 rolling on the roadway C, above the channel 2, via an articulated arm 6 which comprises a substantially horizontal portion 60, connected to the vehicle 5 at one of its ends through a ball 61, and connected by its another end through a ball 62 to the carriage 4, and more exactly to the end of a mast 44 fixedly secured to the carriage 4, and which emerges vertically from the channel 2 through the slot 32 of the decking 3.
On notera que le platelage est, de manière optionnelle, muni d'un élément de couverture 33, en matériau souple, apte à recouvrir la fente 32, visible sur la figure 1, et qui s'escamote lors du passage du mât 44.It will be noted that the decking is, optionally, provided with a covering element 33, made of flexible material, capable of covering the slot 32, visible in FIG. 1, and which retracts during the passage of the mast 44.
Le bras articulé 6 renferme des conducteurs électriques, non visibles, permettant de transmettre au véhicule 5 l'énergie électrique captée par les roues 41 sur les rails 22. Cette énergie électrique est utilisée pour alimenter un moyen moteur apte à entraîner en déplacement le véhicule 5.The articulated arm 6 contains electrical conductors, not visible, for transmitting to the vehicle 5 the electrical energy sensed by the wheels 41 on the rails 22. This electrical energy is used to supply a motor means adapted to drive the vehicle 5 .
Selon un mode de réalisation préférentiel, les rails sont alimentés en courant basse tension, inférieure à 1000 V, monophasé 50 Hz, et il alimente un moteur électrique asynchrone ou synchrone tournant à vitesse constante, pour entraîner une pompe hydraulique à volume variable, qui elle-même alimente un ou plusieurs moteurs hydrauliques .According to a preferred embodiment, the rails are supplied with low voltage current, less than 1000 V, single-phase 50 Hz, and it supplies an asynchronous or synchronous electric motor rotating at constant speed, to drive a variable volume hydraulic pump, which it even feeds one or more hydraulic motors.
Le moteur électrique, la pompe hydraulique et le ou les moteurs hydrauliques sont installés dans un véhicule 5 tel que celui représenté sur les figures 4 et 5. Ce véhicule 5 est monté sur des roues 50 à bandage caoutchouc ou pneus, et il est conçu pour rouler librement sur la chaussée, en étant guidé par le chariot 4 auquel il est relié .The electric motor, the hydraulic pump and the hydraulic motor or motors are installed in a vehicle 5 such as that shown in FIGS. 4 and 5. This vehicle 5 is mounted on rubber or tire wheels 50 and is designed to rolling freely on the road, being guided by the carriage 4 to which it is connected.
A cet effet, le véhicule 5 comporte des organes de direction agissant sur des roues 50 directrices, gérés par des moyens de commandes comprenant des moyens permettant de mesurer les écarts angulaires que forme la partie 60 du bras articulé 6 avec, par exemple l ' axe longitudinal du véhicule ou l ' orientation des roues 50 directrices, en sorte d'agir sur les organes de directions afin de corriger la trajectoire du véhicule, comme cela est représenté sur la figure 5.For this purpose, the vehicle 5 comprises steering members acting on steering wheels 50, managed by means of controllers comprising means for measuring the angular deviations formed by the portion 60 of the articulated arm 6 with, for example, the longitudinal axis of the vehicle or the orientation of the steered wheels 50, so as to act on the steering members in order to correct the trajectory of the vehicle, as shown in Figure 5.
On peut comprendre que le chariot 4 assure, outre le captage d'énergie électrique, le guidage du véhicule 5 sans que soit exercée la moindre contrainte des roues 41 sur les rails 22, ne générant ainsi que peu de nuisances sonores et d'usure des éléments en contact.It can be understood that the carriage 4 ensures, in addition to the capture of electrical energy, the guidance of the vehicle 5 without the slightest stress being applied to the wheels 41 on the rails 22, thus generating only a small amount of noise and wear and tear on the wheels. elements in contact.
Le chariot 4 est poussé sur les rails 22 par le véhicule 5, mais il est parfaitement possible de prévoir une autre configuration dans laquelle il est tiré . The carriage 4 is pushed on the rails 22 by the vehicle 5, but it is perfectly possible to provide another configuration in which it is pulled.
