Description

La présente invention concerne des rails à gorge selon le préambule de la revendication 1.The present invention relates to grooved rails according to the preamble of claim 1.

Les rails à gorge sont utilisés pour la réalisation de réseaux ferrés en zone urbaine ou périurbaine, notamment afin de permettre que les voies soient intégrées à la chaussée pour la circulation de véhicules de tout type. De tels réseaux ferrés en zone urbaine sont très souvent réalisés en utilisant soit du rail à gorge, soit du rail vignole suivant les zones de circulation routière. En zone périurbaine, les voies sont couramment raccordées à des réseaux ferrés nouveaux ou existants, c'est-à-dire des réseaux dont les voies sont constituées de rails dépourvus de gorge, c'est-à-dire de rails de type "vignole".The grooved rails are used for the realization of rail networks in urban or peri-urban areas, in particular to allow the tracks to be integrated with the roadway for the circulation of vehicles of any type. Such rail networks in urban areas are very often made using either rail groove or rail vignole following the traffic areas. In peri-urban areas, the tracks are currently connected to new or existing rail networks, ie networks whose tracks are made up of rails without throats, that is to say, "vignole" type rails. ".

En Europe, les rails de type "vignole" sont définis notamment par la norme EN 13674-1. Les rails ayant un profil 49E1, 54E3 ou 49E5 défini dans cette norme sont couramment retenus pour les réseaux urbains et périurbains installés en Europe.In Europe, the "Vignole" type rails are defined in particular by the EN 13674-1 standard. Rails with a 49E1, 54E3 or 49E5 profile defined in this standard are commonly used for urban and peri-urban networks in Europe.

Une autre norme européenne EN 14811 prévoit un certain nombre de rails à gorge susceptibles d'être raccordés aux rails précédemment cités. Il s'agit par exemple des profils 60R1, 59R1, 59R2 60R2. Il existe d'autres rails non normalisés tels que les profils, RI55-NK ou RI54-G2. Quel que soit le type de montage de ces rails, que ceux-ci soient posés verticalement ou avec une inclinaison, le franchissement de l'interconnexion entre le réseau en rails à gorge et le réseau en rails "vignole" provoque un inconfort pour les passagers du véhicule circulant sur la voie.Another European standard EN 14811 provides a number of groove rails that can be connected to the rails mentioned above. These are, for example, profiles 60R1, 59R1, 59R2 60R2. There are other non-standard rails such as profiles, RI55-NK or RI54-G2. Whatever the type of mounting of these rails, whether they are placed vertically or with an inclination, the crossing of the interconnection between the grooved rail network and the "vignole" rail network causes discomfort for the passengers of the vehicle traveling on the track.

En effet les profils des champignons des rails connus actuellement ne sont pas raccordables directement du fait de leur différence de géométrie, il est impossible d'obtenir la continuité géométrique du plan de roulement supérieur, et simultanément la continuité géométrique de la face de guidage latérale. Le confort optimal et la réduction des nuisances sonores ne peuvent être obtenus que lorsque le guidage des roues est assuré sans aucune discontinuité, quel que soit le niveau d'usure des roues.In fact the profiles of the mushrooms of the rails known at present are not directly connectable because of their difference in geometry, it is impossible to obtain the geometrical continuity of the upper rolling plane, and simultaneously the geometrical continuity of the lateral guide face. Optimum comfort and noise reduction can only be achieved when wheel guidance is provided without any discontinuities, regardless of the level of wheel wear.

On connaît selon le brevet N° 2 827 879 un rail à gorge dont la table de roulement supérieure présente une tangente inclinée par rapport à la face plane d'appui, mais ce rail n'offre pas de solution de continuité au raccordement avec un rail de type vignole 49E1 ou 54E3 auquel il serait associé.We know according to the patent N ° 2,827,879 a grooved rail whose upper tread has a tangent inclined relative to the flat face support, but this rail does not offer a solution of continuity to the connection with a rail type Vignole 49E1 or 54E3 with which it would be associated.

Egalement selon le brevet N° 2 854 410 , on connaît un rail à gorge caractérisé en ce que la face supérieure de roulement est raccordée à la face latérale de guidage inclinée avec une pente de 1/20 par deux portions convexes successives de rayons de courbure sensiblement égaux à 60 mm et 13 mm. On constate que les rails présentant cette caractérisation ne peuvent offrir de solution de continuité au raccordement avec un rail de type vignole 49E1 ou 54E3 auquel ils seraient associés.Also according to the patent N ° 2,854,410 , there is known a grooved rail characterized in that the upper tread face is connected to the inclined lateral guide face with a slope of 1/20 by two successive convex portions of radii of curvature substantially equal to 60 mm and 13 mm. It can be seen that the rails presenting this characterization can not offer a solution of continuity to the connection with a vignette type rail 49E1 or 54E3 with which they would be associated.

L'invention a pour but de proposer un rail à gorge permettant d'offrir une solution de continuité au raccordement avec un rail de type vignole 49E1, 54E3 ou 49E5 ou tout rail ayant des caractéristique similaires au niveau du champignon et de procurer un confort amélioré aux passagers lors du franchissement d'une liaison d'un type de rail à l'autre.The purpose of the invention is to propose a grooved rail which makes it possible to offer a continuity solution when connected to a Vignole type rail 49E1, 54E3 or 49E5 or any rail having similar characteristics at the level of the mushroom and to provide improved comfort. passengers when crossing a route from one type of rail to another.

A cet effet, l'invention a pour objet un rail à gorge conforme à la revendication 1.For this purpose, the invention relates to a grooved rail according to claim 1.

Suivant des modes particuliers de réalisation, le rail à gorge comporte l'une ou plusieurs des caractéristiques des revendications dépendantes 2 à 8.According to particular embodiments, the grooved rail comprises one or more of the features of the dependent claims 2 to 8.

L'invention a également pour objet une voie de chemin de fer, pour tramway ou tram-train conforme à la revendication 9.The invention also relates to a railroad track, tramway or tram-train according to claim 9.

L'invention a également pour objet une voie de chemin de fer, pour tramway ou tram-train conforme à la revendication 10.The invention also relates to a railway track, for tram or tram-train according to claim 10.

Suivant des modes particuliers de réalisation, la voie de chemin de fer comporte les caractéristiques de la revendication dépendante 11.According to particular embodiments, the railroad track includes the characteristics of the dependent claim 11.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins sur lesquels :

  • la Figure 1 est un profil en section d'un rail à gorge selon l'invention ;
  • la Figure 2 est une vue en section du raccordement entre un profil de rail à gorge selon l'invention tel que représenté sur la Figure 1 et un rail "vignole" de type 49E1 ;

  • la Figure 6 est une vue identique à celle de la Figure 2 montrant le raccordement du rail à gorge selon l'invention de la Figure 5 à un rail "vignole" 49E5.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the drawings in which:
  • the Figure 1 is a sectional profile of a grooved rail according to the invention;
  • the Figure 2 is a sectional view of the connection between a grooved rail profile according to the invention as shown in FIG. Figure 1 and a "vignole" rail of type 49E1;
  • the Figure 3 is a view of a grooved rail with the rolling table inclined to 1/40 th according to the invention;

  • the Figure 6 is a view identical to that of the Figure 2 showing the connection of the grooved rail according to the invention of the Figure 5 to a rail "vignole" 49E5.

Le rail à gorge illustré sur la Figure 1 est destiné à constituer un rail pour voie courante, ou pour un appareil de voie. Un tel rail est propre à être installé dans une chaussée affleurant sensiblement la partie supérieure du rail.The grooved rail illustrated on the Figure 1 is intended to constitute a rail for a common track, or for a switchgear. Such a rail is suitable for being installed in a floor substantially flush with the upper part of the rail.

Comme connu en soi, un tel rail comporte un patin 12, une âme verticale 14 reposant dans la partie médiane du patin 12 et un champignon 16 surmontant l'âme 14. Une bavette 18 prolonge latéralement le champignon 16 au sommet de l'âme 14. Une gorge 20 s'ouvrant sur le dessus est délimitée entre le champignon 16 et la bavette 18.As known per se, such a rail comprises a shoe 12, a vertical core 14 resting in the middle part of the shoe 12 and a mushroom 16 overlying the core 14. A flap 18 laterally extends the mushroom 16 to the top of the core 14 A groove 20 opening on the top is delimited between the mushroom 16 and the flap 18.

De façon conventionnelle, dans la présente demande, l'expression "sensiblement égal à" exprimera une relation d'égalité à plus ou moins 5 %.Conventionally, in the present application, the expression "substantially equal to" will express a relationship of equality at plus or minus 5%.

Le patin 12 présente une surface d'appui 22 plane propre à être posée sur une traverse, ou sur une dalle en béton ou tout autre support approprié préinstallé. Cette surface d'appui a une largeur de 125 mm, le patin ayant une épaisseur comprise entre 10,5 mm au niveau de ses bords latéraux et 27,5 mm dans sa partie médiane depuis laquelle s'étend l'âme 14. Les faces supérieures du patin convergent vers l'âme et définissent avec la surface d'appui 22 du patin une pente de 1/7,81 au voisinage du bord puis une pente de 1/3 au voisinage de l'âme 14.The pad 12 has a flat bearing surface 22 to be placed on a cross, or a concrete slab or other suitable support preinstalled. This bearing surface has a width of 125 mm, the pad having a thickness of between 10.5 mm at its lateral edges and 27.5 mm in its middle part from which the core 14 extends. The faces upper skate converge towards the core and define with the bearing surface 22 of the pad a slope of 1 / 7,81 near the edge and then a slope of 1/3 in the vicinity of the core 14.

L'âme 14 a une épaisseur de 13 mm. Le plan vertical P du rail formant ici le plan médian de l'âme 14 s'étend rigoureusement perpendiculairement à la surface d'appui 22 du patin.The core 14 has a thickness of 13 mm. The vertical plane P of the rail here forming the median plane of the core 14 extends rigorously perpendicular to the bearing surface 22 of the pad.

Le champignon 16 s'étend dans le prolongement de l'âme 14. Il présente une portion en porte-à-faux latérale par rapport à l'âme 14 tournée du côté opposé à la bavette 18.The mushroom 16 extends in the extension of the core 14. It has a lateral cantilevered portion relative to the core 14 turned away from the flap 18.

Le champignon du rail à gorge suivant la Figure 1 présente une surface supérieure de roulement 24 faiblement convexe délimitant un plan de roulement PR s'étendant perpendiculairement au plan vertical P du rail et parallèlement à la surface d'appui 22.The mushroom of the grooved rail following the Figure 1 has a slightly convex upper rolling surface 24 delimiting a running surface PR extending perpendicularly to the vertical plane P of the rail and parallel to the bearing surface 22.

La surface supérieure de roulement 24 est cylindrique de section en arc de cercle. Elle présente un grand rayon de courbure R1 sensiblement égal à 300 mm. Le centre de la surface supérieure de roulement est déporté de 18,5 mm par rapport au plan vertical du rail du côté opposé à la bavette 18.The upper rolling surface 24 is cylindrical in section arcuate. It has a large radius of curvature R 1 substantially equal to 300 mm. The center of the upper running surface is offset 18.5 mm from the vertical plane of the rail on the opposite side to the flap 18.

A l'opposé de la bavette 18, le champignon 16 est délimité par une face latérale extérieure 26 s'étendant parallèlement au plan vertical du rail. Cette face latérale 26 est reliée à la surface supérieure de roulement 24 par un congé de rayon de 8 mm prolongé par une portion convexe dont le rayon de courbure est égal à 80 mm.In contrast to the flap 18, the mushroom 16 is delimited by an outer side face 26 extending parallel to the vertical plane of the rail. This side face 26 is connected to the upper running surface 24 by a fillet radius of 8 mm extended by a convex portion whose radius of curvature is equal to 80 mm.

La face inférieure 28 du champignon est inclinée avec une pente de 1/3 par rapport au plan de roulement PR. La hauteur h1 du champignon, mesurée suivant la direction du plan vertical P du rail depuis le plan de roulement PR jusqu'au point d'intersection de la face inférieure 28 avec le plan vertical P du rail considéré comme le plan médian de l'âme est égal à 40,5 mm.The lower face 28 of the mushroom is inclined with a slope of 1/3 relative to the running surface PR. The height h 1 of the mushroom, measured in the direction of the vertical plane P of the rail from the running surface PR to the point of intersection of the lower face 28 with the vertical plane P of the rail considered as the median plane of the soul is equal to 40.5 mm.

En regard de la bavette 18, le champignon 16 présente une face latérale de guidage 30 sensiblement plane et propre à assurer un guidage latéral de la roue du véhicule par contact avec le mentonnet de celle-ci. Cette face latérale de guidage 30 présente une pente de 1/17,2 par rapport au plan vertical P du rail. Ainsi, la surface de guidage 30 et le plan vertical P du rail délimitent un angle obtus s'ouvrant vers le patin 12 du rail.Opposite the flap 18, the mushroom 16 has a guiding lateral face 30 substantially flat and adapted to provide lateral guidance of the wheel of the vehicle by contact with the lug thereof. This lateral guide face 30 has a slope of 1 / 17.2 relative to the vertical plane P of the rail. Thus, the guide surface 30 and the vertical plane P of the rail define an obtuse angle opening towards the pad 12 of the rail.

Cette face latérale de guidage 30 est reliée à la surface supérieure de roulement 24 par deux tronçons convexes 32, 34 ayant respectivement de la surface 24 vers la face 30 un rayon R2 de 80 mm et un rayon R3 de 13 mm.This lateral guide face 30 is connected to the upper rolling surface 24 by two convex sections 32, 34 respectively having the surface 24 towards the face 30 a radius R 2 of 80 mm and a radius R 3 of 13 mm.

Dans ce mode de réalisation, l'extrémité supérieure de la bavette 18 s'étend dans le plan de roulement PR. La largeur de l'ornière 20, mesurée à 14 mm du plan de roulement PR est sensiblement égale à 36 mm. En variante, cette largeur est sensiblement égale à 41 mm.In this embodiment, the upper end of the flap 18 extends in the running surface PR. The width of the rut 20, measured at 14 mm from the running surface PR is substantially equal to 36 mm. In a variant, this width is substantially equal to 41 mm.

La bavette présente sous l'ornière 20 une face inférieure 40 ayant une pente de 1/5ème par rapport au plan de roulement PR. La hauteur h2 de la bavette, mesurée suivant le plan médian de l'âme 14 entre le plan de roulement PR et le point d'intersection entre la face inférieure 40 et le plan vertical P du rail est égale à 64,63 mm. La hauteur totale h du rail prise entre le plan de roulement PR et la face inférieure 22 est égale à 149 mm.The flap present under the rut 20 a lower face 40 having a slope of 1/5 th relative to the running surface PR. The height h 2 of the flap measured along the median plane of the core 14 between the running surface PR and the point of intersection between the lower face 40 and the vertical plane P of the rail is equal to 64.63 mm. The total height h of the rail taken between the running surface PR and the lower face 22 is equal to 149 mm.

La distance D entre la face latérale de guidage 30 et une face latérale du patin du côté opposé à la face latérale est tolérancée à ± 1 mm, de sorte que le rail peut être posé sans réglages additionnels sur des supports prépositionnés ou sur des traverses réalisées en série.The distance D between the lateral guiding face 30 and a lateral face of the pad on the side opposite the lateral face is toleranced to ± 1 mm, so that the rail can be placed without additional adjustments on prepositioned supports or on crosspieces made serial.

Sur la Figure 2 est représenté le raccordement entre un rail "vignole" V de profil 49E1 représenté en trait mixte et le rail à gorge selon l'invention de la Figure 1 représenté en trait plein. Sur cette Figure, les deux rails sont posés de sorte que les plans verticaux des rails notés respectivement Q et P pour le rail "vignole" et le rail à gorge soient parallèles. Les plans de roulement sont également parallèles entre eux.On the Figure 2 is shown the connection between a "vignole" rail V profile 49E1 shown in phantom and the groove rail according to the invention of the Figure 1 represented in full line. In this Figure, the two rails are placed so that the vertical planes of rails respectively Q and P for the "Vignole" rail and the groove rail are parallel. The work schedules are also parallel to each other.

On constate un raccordement parfait entre les deux rails, au niveau de la surface supérieure de roulement, de la face latérale de guidage et des régions convexes de raccordement entre celles-ci.There is a perfect connection between the two rails, at the upper bearing surface, the lateral guide face and the convex connecting regions therebetween.

De manière analogue, un tel raccordement parfait est constaté dans le raccordement entre un rail de profil 54E3 et le rail à gorge de la Figure 1. Les rails à gorge et "vignole" peuvent ainsi être posés tous deux soit verticalement, c'est-à-dire avec les plans verticaux Q et P rigoureusement verticaux, soit tous deux avec une même inclinaison par exemple au 1/20ème, 1/30ème, ou 1/40ème par rapport à la verticale.Similarly, such a perfect connection is found in the connection between a profile rail 54E3 and the groove rail of the Figure 1 . The rails groove and "vignole" can be placed both vertically, that is to say with the vertical planes Q and P rigorously vertical, or both with the same inclination for example 1/20 th , 1 / 30 th , or 1/40 th from the vertical.

Sur la Figure 3 est représenté un autre rail. Les éléments identiques ou correspondant à ceux de la Figure 1 sont désignés par les mêmes numéros de références.On the Figure 3 is represented another rail. Identical elements or corresponding to those of the Figure 1 are designated by the same reference numbers.

Ce rail se distingue essentiellement par l'inclinaison de la face latérale de guidage notée 60 et de la surface supérieure de roulement notée 61. La pente de la face de guidage 60 par rapport au plan vertical P du rail est égale à 1/30,22. Le centre de la surface supérieure de roulement 61 est déporté de 25,64 mm par rapport au plan médian de l'âme 14, son rayon restant égal à 300 mm. Les rayons R2 et R3 des tronçons convexes 32 et 34 sont respectivement égaux à 80 et 13 mm. Le champignon du rail à gorge suivant la Figure 3 présente une surface supérieure de roulement 61 faiblement convexe définissant un plan de roulement PR1 s'étendant avec une inclinaison au 1/40 par rapport à la surface d'appui 22 du patin.This rail is essentially distinguished by the inclination of the lateral guide face 60 noted and the upper running surface noted 61. The slope of the guide face 60 relative to the vertical plane P of the rail is equal to 1/30, 22. The center of the upper running surface 61 is offset by 25.64 mm with respect to the median plane of the core 14, its radius remaining equal to 300 mm. The radii R 2 and R 3 of the convex sections 32 and 34 are respectively equal to 80 and 13 mm. The mushroom of the grooved rail following the Figure 3 has a lower surface of rolling 61 slightly convex defining a running surface PR 1 extending with an inclination to 1/40 relative to the bearing surface 22 of the pad.

La largeur de l'ornière 20 est sensiblement égale à 41 mm. Celle-ci est sensiblement égale à 36 mm dans un autre mode de réalisation.The width of the rut 20 is substantially equal to 41 mm. This is substantially equal to 36 mm in another embodiment.

Les autres dimensions du rail suivant la Figure 3 sont identiques à celles du rail de la Figure 1.The other dimensions of the rail following the Figure 3 are identical to those of the rail of the Figure 1 .

Sur la Figure 4, le rail de la Figure 3 est représenté monté dans le prolongement d'un rail "vignole" V de profil 49E1 posé au 1/40e. Le plan longitudinal P du rail à gorge est vertical. Ainsi, le plan P est décalé angulairement par rapport au plan vertical Q, seul le plan de roulement PR1 est incliné au 1/40°, le rail "vignole", type 49E1 ou 54E3 est posé incliné au 40ème alors que le rail de la Figure 3 est posé avec son plan vertical rigoureusement vertical.On the Figure 4 , the rail of the Figure 3 is shown mounted in the extension of a rail "Vignole" V profile 49E1 placed at 1/40 th . The longitudinal plane P of the grooved rail is vertical. Thus, the plane P is angularly offset relative to the vertical plane Q, only the rolling plane PR 1 is inclined at 1/40 °, the "vignole" rail, type 49E1 or 54E3 is laid inclined at 40 th while the rail of the Figure 3 is posed with its rigorously vertical vertical plane.

Sur la Figure 5 est représenté un autre mode de réalisation du rail selon l'invention. Les éléments identiques ou correspondant à ceux de la Figure 1 sont désignés par les mêmes numéros de références.On the Figure 5 another embodiment of the rail according to the invention is shown. Identical elements or corresponding to those of the Figure 1 are designated by the same reference numbers.

Ce mode de réalisation se distingue essentiellement par des valeurs différentes pour les rayons respectifs R1 à R3, et par un troisième tronçon convexe 70 reliant la face latérale de guidage 30 au deuxième tronçon convexe 34.This embodiment is distinguished essentially by different values for the respective radii R 1 to R 3 , and by a third convex section 70 connecting the lateral guide face 30 to the second convex section 34.

La surface supérieure de roulement 24 présente un rayon de courbure R1 sensiblement égal à 115 mm. Le rayon R2 du premier tronçon convexe 32 est égal 16,5 mm. Le rayon R3 du deuxième tronçon convexe 34 est égal 15,5 mm. Le troisième tronçon convexe 70 a de la surface 24 vers la face 30 un rayon R4 de 7,64 mm.The upper running surface 24 has a radius of curvature R 1 substantially equal to 115 mm. The radius R 2 of the first convex section 32 is equal to 16.5 mm. The radius R 3 of the second convex section 34 is equal to 15.5 mm. The third convex section 70 has from the surface 24 towards the face 30 a radius R 4 of 7.64 mm.

Les autres dimensions du rail suivant la Figure 5 sont identiques à celles du rail de la Figure 1.The other dimensions of the rail following the Figure 5 are identical to those of the rail of the Figure 1 .

Sur la Figure 6 est représenté le raccordement entre un rail "vignole" V de profil 49E5 représenté en trait mixte et le rail à gorge selon l'invention de la Figure 5 représenté en trait plein. Sur cette figure, les deux rails sont posés de sorte que les plans verticaux des rails notés respectivement Q et P pour le rail "vignole" et le rail à gorge soient parallèles. Les plans de roulement sont également parallèles entre eux.On the Figure 6 is shown the connection between a "vignole" rail V profile 49E5 shown in phantom and the grooved rail according to the invention of the Figure 5 represented in full line. In this figure, the two rails are placed so that the vertical planes rails respectively Q and P for the "Vignole" rail and the groove rail are parallel. The work schedules are also parallel to each other.

De manière analogue, les rails à gorge et "vignole" peuvent être posés tous deux avec une même inclinaison par exemple au 1/20ème, 1/30ème, ou 1/40ème par rapport à la verticale.Similarly, the grooved rails and "vignole" can be laid both with the same inclination, for example 1/20, 1/30, or 1/40 with respect to the vertical.

On constate un raccordement parfait entre les deux rails, au niveau de la surface supérieure de roulement, de la face latérale de guidage et des régions convexes de raccordement entre celles-ci.There is a perfect connection between the two rails, at the upper bearing surface, the lateral guide face and the convex connecting regions therebetween.

Dans les différents cas envisagés, avec un tel montage, on constate un raccordement parfait entre les faces supérieures de roulement et les faces latérales de guidage ainsi que des régions convexes successives de raccordement entre ces deux surfaces.In the various cases envisaged, with such an assembly, there is a perfect connection between the upper bearing faces and the lateral guide faces as well as successive convex regions of connection between these two surfaces.

On comprend que la parfaite continuité entre les rails assure un confort amélioré des passagers, puisque aucune secousse n'est ressentie lors de la circulation du véhicule sur le raccordement. Elle supprime les nuisances acoustiques et vibratoires et améliore ainsi l'environnement.It is understood that the perfect continuity between the rails ensures improved passenger comfort, since no jolt is felt when the vehicle is traveling on the connection. It eliminates noise and vibration and improves the environment.
