Abstract
Description
Les tramways assurant le transport rapide de personnes dans les grandes villes doivent être conçus de telle manière que l'accès et la descente des passagers puissent se faire rapidement à la station. Les véhicules usuels ont généralement un plancher dont le niveau est élevé du fait de la dimension des roues motrices nécessaires. Il en résulte que l'accès se fait par l'intermédiaire d'au moins trois marches ce qui ralentit la montée et la descente des passagers, surtout des moins agiles d'entre eux.Trams providing rapid transport of people in large cities must be designed in such a way that passengers can get in and out of the station quickly. Conventional vehicles generally have a floor whose level is high due to the size of the drive wheels required. As a result, access is via at least three steps which slows the ascent and descent of passengers, especially the less agile of them.
Par le brevet CH-A-247 907 (Straub), on connait déjà un tramway selon le préambule de la revendication 1 dont les roues motrices sont de plus grand diamètre et les roues tractées de plus petit diamètre, de sorte que le plancher, auquel les bogies des roues tractées sont reliés, peut être abaissé par rapport au plancher auquel sont reliés les bogies des roues motrices, afin de rapprocher du sol le plancher auquel sont reliées les roues tractées et y faciliter la montée et la descente des passagers.By patent CH-A-247,907 (Straub), a tram is already known according to the preamble of
Par le brevet FR-A-2440300 (Socimi), on connait également un convoi de type tramway dont la partie porteuse repose sur des bogies munis de roues de plus petit diamètre que les roues motrices afin de réduire ainsi la garde au sol des voitures et faciliter la montée et la descente des usagers.By patent FR-A-2440300 (Socimi), we also know a tram-type convoy, the load-bearing part of which rests on bogies fitted with wheels of smaller diameter than the drive wheels in order to thus reduce the ground clearance of cars and facilitate the ascent and descent of users.
Le but de la présente invention vise à réaliser des véhicules ferroviaires en particulier urbains dont le plancher est sensiblement abaissé par rapport aux réalisations connues, et auxquels l'accès à partir du trottoir se fait à l'aide d'un seul marchepied intermédiaire, soit par le franchissement de deux marches seulement. L'invention concerne également un bogie qui, uniquement porteur, est réalisé de telle façon que, même en l'absence d'une suspension élastique primaire, la charge se répartit également entre les 4 roues qui peuvent alors être de très petit diamètre, ce qui autorise un abaissement important du niveau du plancher, et ceci de la plus grande partie de sa surface.The object of the present invention is to produce rail vehicles, in particular urban vehicles, the floor of which is substantially lowered compared with known embodiments, and to which access from the sidewalk is done using a single intermediate step, namely by crossing only two steps. The invention also relates to a bogie which, only carrying, is produced in such a way that, even in the absence of a primary elastic suspension, the load is evenly distributed between the 4 wheels which can then be of very small diameter, this which allows a significant lowering of the level of the floor, and this of most of its surface.
Un autre avantage de l'invention réside dans le fait que la réduction du nombre des marches, à deux seulement, autorise la suppression du puits de descente qui existe dans les constructions connues, puits d'accès à la porte et rend possible l'exécution du plancher abaissé sur un seul et même niveau et ceci même au voisinage des portes, les deux marches à franchir l'étant à l'aide du seul marchepied intermédiaire nécessaire qui est escamotable et peut être placé à l'extérieur du véhicule. La suppression du puits de descente permet en outre de réaliser le longeron de bordure du plancher rectiligne, ce qui est plus économique.Another advantage of the invention resides in the fact that the reduction in the number of steps, to only two, allows the suppression of the downpipe which exists in known constructions, access pits to the door and makes execution possible. of the lowered floor on one and the same level and this even in the vicinity of the doors, the two steps to be crossed using the only necessary intermediate step which is retractable and can be placed outside the vehicle. The elimination of the downspout also makes it possible to produce the side rail of the rectilinear floor, which is more economical.
Plus précisément, l'invention concerne un véhicule ferroviaire en particulier urbain dont la caisse, constituée d'un ou de plusieurs tronçons, comprend un plancher bordé de chaque côté par un longeron, des parois équipées de portes et fenêtres, un toit, et est supportée par au moins deux bogies dont au moins un, non-motorisé, est uniquement porteur, ce bogie porteur étant muni de roues de petit diamètre autorisant un abaissement important du niveau du plancher du véhicule au droit de la zone correspondant à ce bogie, l'abaissement de niveau étant suffisant pour qu'un seul marchepied, placé à un niveau situé à mi-hauteur entre la chaussée et le plancher du véhicule, est nécessaire pour permettre l'accès, respectivement la sortie des passagers du véhicule, caractérisé en ce que la surface du plancher abaissé est plane, en ce sens qu'elle est exempte de puits de descente d'escalier, les longerons de bordure du plancher étant, d'un bout à l'autre de la zone du véhicule où le plancher est abaissé, situés à un même niveau et en ce que le marchepied est escamotable et est placé en position d'utilisation simultanément avec l'ouverture de la porte correspondante.More specifically, the invention relates to a railway vehicle, in particular an urban vehicle, the body of which, consisting of one or more sections, comprises a floor bordered on each side by a spar, walls fitted with doors and windows, a roof, and is supported by at least two bogies of which at least one, non-motorized, is only load-bearing, this load-bearing bogie being provided with small diameter wheels allowing a significant lowering of the level of the vehicle floor in line with the area corresponding to this bogie, l lowering being sufficient for a single step, placed at a level located halfway between the roadway and the vehicle floor, is necessary to allow access, respectively the exit of passengers from the vehicle, characterized in that the lowered floor surface is flat, in the sense that it is free from stairwells, the floor edge spars being, from one end to the other of the area of the vehicle where the floor is at lowered, located at the same level and in that the step is retractable and is placed in the position of use simultaneously with the opening of the corresponding door.

La fig. 1 représente, à titre d'exemple et schématiquement, un bogie porteur de grande sécurité en ce sens qu'il peut franchir des zones où les deux rails de la voie sont gauches, et étant équipé de petites roues nécessaires à la réalisation du véhicule. Ce bogie porteur est constitué de deux poutres longitudinales (1) et (2) qui comportent chacune à ses extrémités deux roues avant (3 et 4) et arrière (5 et 6). Dans le cas de cette figure, ces roues sont représentées étant montées en porte-à-faux à chaque extrémité des deux poutres longitudinales. Elles sont donc toutes indépendantes. Une autre solution constructive aurait été possible, notamment en reliant les deux roues avant (3 et 4) et arrière (5 et 6) l'une à l'autre par un axe fixé aux extrémités des poutres longitudinales (1 et 2) par une liaison à rotule autorisant des mouvements verticaux indépendants des roues. Le bogie selon cette figure est représenté sans freins. Il va de soi que les roues peuvent être équipées de freins dont l'action peut se faire sur la bandage extérieur ou par l'intermédiaire d'un disque.Fig. 1 shows, by way of example and schematically, a bogie carrying great security in the sense that it can cross zones where the two rails of the track are left, and being equipped with small wheels necessary for the production of the vehicle. This carrier bogie consists of two longitudinal beams (1) and (2) which each have at its ends two front wheels (3 and 4) and rear (5 and 6). In the case of this figure, these wheels are shown being mounted in cantilever at each end of the two longitudinal beams. They are therefore all independent. Another constructive solution would have been possible, in particular by connecting the two front (3 and 4) and rear (5 and 6) wheels to each other by an axis fixed to the ends of the longitudinal beams (1 and 2) by a ball joint allowing vertical movements independent of the wheels. The bogie according to this figure is shown without brakes. It goes without saying that the wheels can be fitted with brakes, the action of which can be carried out on the outer tire or by means of a disc.
Les deux poutres longitudinales (1 et 2) sont reliées l'une à l'autre par une première poutre transversale (7) qui, dans le cas de la fig., est soudée en (8) à l'une de ses extrémités, au milieu de la longueur de la poutre (2), tandis qu'à l'autre extrémité (9) la liaison au milieu de la poutre (1) est faite au moyen d'un palier de guidage permettant une oscillation de la poutre longitudinale (1) autour de l'axe horizontal de la première poutre transversale (7). Ce degré de liberté autorise - sans avoir recours à une suspension élastique des roues - la circulation d'un tel bogie sur des voies gauches à savoir sur deux rails qui ne sont pas dans un même plan. Dans ce cas, les deux poutres longitudinales (1 et 2) restent parallèles aux rails correspondants, la différence d'angle existant entre ceux-ci étant absorbée par une rotation se faisant au niveau du palier (9).The two longitudinal beams (1 and 2) are connected to each other by a first transverse beam (7) which, in the case of FIG., Is welded at (8) at one of its ends, in the middle of the length of the beam (2), while at the other end (9) the connection in the middle of the beam (1) is made by means of a guide bearing allowing an oscillation of the longitudinal beam (1) around the horizontal axis of the first transverse beam (7). This degree of freedom allows - without resorting to an elastic suspension of the wheels - the circulation of such a bogie on left tracks, namely on two rails which are not in the same plane. In this case, the two longitudinal beams (1 and 2) remain parallel to the corresponding rails, the difference in angle existing between them being absorbed by a rotation taking place at the level of the bearing (9).
Au milieu de sa longueur, la première poutre transversale (7) comprend un support de butée (16) représenté ici par un tube vertical soudé rigidement à cette première poutre transversale. Ce support se termine par une butée tournante (15) qui porte une seconde poutre transversale (10) en son milieu. Cette liaison est faite de telle façon que cette seconde poutre peut osciller autour d'un axe vertical mais pas s'incliner. Cette seconde poutre transversale (10) se termine à ses deux extrémités (11 et 12) par un support recevant une suspension élastique (13-14) représentée ici sous la forme d'un ressort à boudin, sur laquelle repose la caisse du véhicule non-représentée au dessin. Là également, au lieu de monter de tels ressorts, il est possible de prévoir de nombreux autres systèmes, par exemple des ressorts à lames, en caoutchouc, pneumatiques, etc.In the middle of its length, the first transverse beam (7) comprises an abutment support (16) represented here by a vertical tube rigidly welded to this first transverse beam. This support ends with a rotary stop (15) which carries a second transverse beam (10) in the middle. This connection is made in such a way that this second beam can oscillate around a vertical axis but not tilt. This second transverse beam (10) ends at its two ends (11 and 12) by a support receiving an elastic suspension (13-14) represented here in the form of a coil spring, on which rests the body of the vehicle not -represented in the drawing. Again, instead of mounting such springs, it is possible to provide many other systems, for example leaf springs, rubber, pneumatic, etc.
Le fonctionnement de l'ensemble est le suivant:
- Les deux ressorts (13 et 14) absorbent les chocs verticaux qui se produisent lors du roulement et améliorent le confort. Ils transmettent le poids de la caisse aux deux extrémités de la seconde poutre transversale (10) qui, elle, le reporte sur la butée tournante (15) puis au support (16) puis à la première poutre transversale (7), soit en un point situé au milieu de l'écartement et au milieu de l'empattement du bogie. De cette façon, cette charge se répartit également entre les 4 roues du bogie par le jeu de l'articulation (9). Lors d'un virage, la caisse prenant momentanément une direction différente du bogie, cette différence est absorbée par une rotation qui se fait au niveau de la butée (15). L'inclinaison de la caisse par rapport au bogie est absorbée par les suspensions élastiques gauche et droite (13 et 14).
- The two springs (13 and 14) absorb the vertical shocks that occur during rolling and improve comfort. They transmit the weight of the body to the two ends of the second transverse beam (10) which, for its part, transfers it to the rotary stop (15) then to the support (16) then to the first transverse beam (7), or in one point located in the middle of the spacing and in the middle of the wheelbase of the bogie. In this way, this load is also distributed between the 4 wheels of the bogie by the play of the articulation (9). During a turn, the body momentarily taking a different direction from the bogie, this difference is absorbed by a rotation which takes place at the stop (15). The inclination of the body relative to the bogie is absorbed by the elastic left and right suspensions (13 and 14).
La fig. 1 représente une disposition schématique dans laquelle les deux poutres transversales (7 et 10), les butées (16 et 15), les suspensions élastiques (13 et 14) sont représentées pour la clarté du dessin, ces pièces étant disposées les unes au-dessus des autres. En fait, dans la réalité, ces pièces sont imbriquées les unes dans les autres. La première poutre transversale est creuse et comporte à son intérieur la seconde, les faces inférieures d'appui des ressorts sont au niveau du dessous des poutres longitudinales (1 et 2), les faces supérieures étant un peu plus hautes que le niveau des roues.Fig. 1 shows a schematic arrangement in which the two transverse beams (7 and 10), the stops (16 and 15), the elastic suspensions (13 and 14) are shown for clarity of the drawing, these parts being arranged one above the other others. In fact, in reality, these pieces are nested one inside the other. The first transverse beam is hollow and has the second inside, the lower bearing surfaces of the springs are at the level of the underside of the longitudinal beams (1 and 2), the upper faces being a little higher than the level of the wheels.
Ce bogie permet d'équilibrer les charges sur les 4 roues, sans avoir recours à une suspension élastique primaire importante qui devrait permettre la compensation du gauchissement de la voie. Cette disposition particulière autorise la réalisation de roues de très petit diamètre, par conséquent aussi celle de véhicules ferroviaires dont le plancher (19) est nettement abaissé sur toute sa surface dans le cas des remorques (fig. 6), et sur presque toute sa surface dans le cas de véhicules comportant un bogie moteur (18) fig. 2, et deux bogies moteurs (18) fig. 3, 4, 5.This bogie makes it possible to balance the loads on the 4 wheels, without having to resort to a significant primary elastic suspension which should allow the compensation of the warping of the track. This particular arrangement allows the production of wheels of very small diameter, therefore also that of railway vehicles whose floor (19) is clearly lowered over its entire surface in the case of trailers (fig. 6), and over almost its entire surface. in the case of vehicles comprising a motor bogie (18) fig. 2, and two motor bogies (18) fig. 3, 4, 5.
Cette disposition a l'avantage de réaliser le plancher dans toute la zone où il est abaissé sur un seul et même niveau, même au voisinage des portes d'accès, et d'autoriser l'accès par un seul marchepied intermédiaire escamotable placé hors de la caisse, comme le montrent les fig. 7 et 8. Le plancher de la caisse repose sur une poutraison comprenant un longeron rectiligne de bordure du plancher (21) qui s'étend d'un bout à l'autre de la partie abaissée de la caisse, sans être interrompu par un puits de descente à un marchepied.This arrangement has the advantage of making the floor in the entire area where it is lowered on one and the same level, even in the vicinity of the access doors, and of allowing access by a single retractable intermediate step placed out of the body, as shown in figs. 7 and 8. The floor of the box rests on a beam comprising a rectilinear spar at the edge of the floor (21) which extends from one end to the other of the lowered part of the box, without being interrupted by a well. downhill to a step.
Enfin, la fig. 9 montre une extrémité du véhicule comprenant un bogie moteur (18) dont le diamètre des roues doit être suffisant pour obtenir l'adhérence nécessaire, ce qui impose que le niveau du plancher recouvrant les bogies moteurs est nettement plus élevé que celui du reste du véhicule qui comprend un escalier (33) ayant - sur cette figure - 2 marchepieds intermédiaires permettant l'accès des personnes aux sièges (30) et (32), une main courante (34) facilitant le passage de l'escalier.Finally, fig. 9 shows one end of the vehicle comprising a motor bogie (18) whose wheel diameter must be sufficient to obtain the necessary grip, which means that the level of the floor covering the motor bogies is significantly higher than that of the rest of the vehicle which includes a staircase (33) having - in this figure - 2 intermediate steps for providing access for people to the seats (30) and (32), a handrail (34) facilitating the passage of the stairs.
