Abstract
Description
Dispositif de calage d'une lame ressort sur une traverse de chemin de fer. Device for wedging a leaf spring on a railway sleeper.
La présente invention concerne un dispositif de calage d'une lame ressort sur une traverse de chemin de fer.The present invention relates to a device for wedging a leaf spring on a railway sleeper.
Les systèmes de fixation d'un rail de chemin de fer sur une traverse tels que ceux décrits dans la demande de brevet FR 88/10759 ou dans les brevets 1228126 et FR 2 287 551 comprennent comme éléments de fixation une lame ressort, une butée isolante interposée entre ladite lame et le patin du rail et un moyen de fixation et de serrage de la lame sur la traverse.The fastening systems of a railroad rail on a sleeper such as those described in patent application FR 88/10759 or in patents 1228126 and FR 2 287 551 include as fixing elements a leaf spring, an insulating stop interposed between said blade and the rail pad and a means of fixing and clamping the blade on the crosspiece.
Ces systèmes prévoient que l'arrière de la lame ressort appuie sur une plaquette de répartition de la pression se trouvant en contact avec le talon arrière de ladite lame. Cette plaquette est généralement pourvue d'une rainure qui reçoit et positionne le talon arrière de la lame pour éviter sa rotation.These systems provide that the rear of the spring blade bears on a pressure distribution plate which is in contact with the rear heel of said blade. This plate is generally provided with a groove which receives and positions the rear heel of the blade to prevent its rotation.
Dans les dispositifs traditionnels, la plaquette d'appui est réalisée par cisaillage d'un petit plat laminé en acier ordinaire. Elle peut être aussi réalisée par moulage en matière plastique pour éviter de blesser le béton de la traverse.In traditional devices, the support plate is produced by shearing a small flat laminated plain steel. It can also be made by plastic molding to avoid injuring the concrete of the crosspiece.
Cette plaquette peut être soit prémoπtée sur la traverse lors de la fabrication de cette dernière ou bien être ajoutée après coup sur le site.This plate can either be premoπtée on the crosspiece during the manufacture of the latter or be added afterwards on the site.
Les dimensions de la plaquette sont conditionnées par la répartition de la pression qui doit s'exercer sur une large surface pour éviter des problèmes liés à la résistance du matériau constituant la traverse (bois ou béton).The dimensions of the plate are conditioned by the distribution of the pressure which must be exerted on a large surface to avoid problems linked to the resistance of the material constituting the crosspiece (wood or concrete).
L'inconvénient de ce système réside surtout dans son prix car ce petit morceau de plat en acier laminé coûte relativement cher, en particulier parce qu'il possède une rainure dont la réalisation nécessite un cylindre de laminoir spécial et que étant destiné à un type précis de lame, il est fabriqué en quantité insuffisante pour revenir à un prix intéressant.The disadvantage of this system lies above all in its price because this small piece of flat rolled steel is relatively expensive, in particular because it has a groove whose realization requires a special rolling mill cylinder and that being intended for a specific type blade, it is manufactured in insufficient quantity to return to an attractive price.
Dans le cas de la demande FR 88 10759, on a affaire à des traverses en béton et on cherche précisément une,pose simplifiée _ιt économique.In the case of application FR 88 10759, we are dealing with concrete sleepers and we are looking specifically for a, simplified installation _ιt economic.
La présente invention a pour but de résoudre ce nouveau problème technique de manière satisfaisante en proposant un dispositif de calage d'une lame ressort sur une traverse de chemin de fer, ladite lame ressort faisant partie d'un système de fixation d'un rail sur une traverse, du type comprenant :The object of the present invention is to solve this new technical problem in a satisfactory manner by proposing a device for wedging a leaf spring on a railroad sleeper, said leaf spring forming part of a system for fixing a rail on a cross member, of the type comprising:
- un moyen de serrage passant au travers d'une ouverture réalisée dans la lame ressort par enlèvement d'un riblon de matière et dont le verrouillage dans la traverse permet d'appuyer ladite lame contre le patin du rail, eta clamping means passing through an opening made in the leaf spring by removing a ripple of material and the locking of which in the cross member enables said blade to be pressed against the pad of the rail, and
- des moyens de blocage et d'appui du talon arrière de la lame ressort sur la traverse, caractérisé en ce que lesdits moyens de blocage et d'appui comprennent des saillies verticales réalisées dans la masse de la traverse et définissant un logement destiné à recevoir ledit riblon de façon horizontale sur lequel le talon arrière de la lame ressort vient en contact d'appui.- means for blocking and supporting the rear heel of the leaf spring on the cross member, characterized in that said blocking and supporting means comprise vertical projections formed in the mass of the cross member and defining a housing intended to receive said riblon horizontally on which the rear heel of the leaf spring comes into bearing contact.
Selon une autre caractéristique du dispositif de l'invention, le bord extérieur du talon arrière de la lame ressort vient en appui latéral de butée sur lesdites saillies.According to another characteristic of the device of the invention, the outer edge of the rear heel of the leaf spring comes into abutment lateral abutment on said projections.
L'ouverture de la lame ressort est réalisée généralement par poinçonnage à froid. Les dimensions de cette ouverture (25 x 30 mm) et donc celles du riblon, c'est-à-dire de la pièce de matière enlevée pour réaliser ladite ouverture, sont suffisantes pour répartir convenablement la pression exercée par le talon arrière de la lame ressort sur la traverse en béton. Le riblon a sensiblement pour forme la réunion de deux demi-cercles dont les centres sont espacés.The opening of the spring leaf is generally carried out by cold punching. The dimensions of this opening (25 x 30 mm) and therefore those of the riblon, that is to say of the piece of material removed to make said opening, are sufficient to properly distribute the pressure exerted by the rear heel of the blade spring on the concrete sleeper. The riblon substantially has the form of the meeting of two semicircles whose centers are spaced.
Jusqu'à présent, ce riblon était jeté à la mitraille, désormais il sera utilisé comme plaquette d'appui et évitera l'achat et la fabrication de plaquettes spéciales. Cette solution permet aussi de fabriquer toujours les mêmes lames ressort, qu'elles soient destinées à la pose sur traverse en bois comme dans le brevet FR 2287 551, ou qu'elles soient destinées à la pose sur traverse béton comme dans la demande FR 8810759. Dans la pose sur traverse en bois, on continuera à utiliser un petit rectangle d'acier plat rainé tandis que dans la pose sur béton on utilisera le riblon provenant de la réalisation de l'ouverture de ladite lame. L'invention sera mieux comprise à la lecture de la description qui va suivre accompagnée des dessins sur lesquels :Until now, this riblon was thrown into the grape shot, now it will be used as a support plate and avoid the purchase and manufacture of special plates. This solution also makes it possible to always manufacture the same spring blades, whether they are intended for installation on a wooden sleeper as in patent FR 2287 551, or whether they are intended for installation on a concrete sleeper as in application FR 8810759 In the pose on wooden cross, we will continue to use a small rectangle of grooved flat steel while in laying on concrete we will use the riblon from the realization of the opening of said blade. The invention will be better understood on reading the description which follows, accompanied by the drawings in which:
La figure 1 représente une vue de dessus d'une lame ressort telle qu'elle est présentée dans l'état de la technique.FIG. 1 represents a top view of a leaf spring as it is presented in the state of the art.
La figure 2 représente une vue en perspective d'un riblon provenant de la lame ressort de la figure 1.FIG. 2 represents a perspective view of a riblon coming from the leaf spring of FIG. 1.
La figure 3 représente une vue de dessus d'un système de fixation d'un rail de chemin de fer sur une traverse avec le dispositif de calage de l'invention.FIG. 3 represents a top view of a system for fixing a railroad rail on a sleeper with the wedging device of the invention.
La figure 4 représente une vue latérale du système de fixation de la figure 3.FIG. 4 represents a side view of the fixing system of FIG. 3.
La figure i représente une lame ressort 1 de forme sensiblement trapézoïdale dans laquelle est réalisée par enlèvement de matière une ouverture 4 (par exemple par poinçonnage à froid) . La pièce résultant de cette opération est un riblon 5 représenté sur la figure 2 qui a les mêmes dimensions que celles de l'ouverture 4. Ce riblon 5 était habituellement jeté à la mitraille, or ses dimensions sont telles qu'il a une surface suffisante pour servir de plaquette d'appui pour la lame ressort 1 lorsque celle-ci est verrouillé en position de fixation du rail. Selon l'invention, on conserve donc ce riblon 5 pour l'utiliser comme plaquette d'appui.FIG. I represents a leaf spring 1 of substantially trapezoidal shape in which an opening 4 is produced by removing material (for example by cold punching). The part resulting from this operation is a riblon 5 shown in FIG. 2 which has the same dimensions as those of the opening 4. This riblon 5 was usually thrown into the scrap metal, but its dimensions are such that it has a sufficient surface to serve as a support plate for the leaf spring 1 when the latter is locked in the rail fixing position. According to the invention, this ratchet 5 is therefore kept for use as a support plate.
La figure 3 représente un système de fixation tel que celui qui est décrit dans la demande 88 10759 mais avec le dispositif de calage de l'invention. Le système de fixation comprend notamment un moyen de serrage 3 passant au travers de l'ouverture 4 réalisée dans la lame ressort 1 par enlèvement du riblon 5 de matière. Le verrouillage par exemple par vissage du moyen de serrage 3 dans la traverse 2 au travers de la lame 1 permet d'appuyer la lame ressort 1 contre le patin 6 du rail R. L'extrémité avant 1A de la lame vient donc en contact d'appui sur une butée isolante 9 interposée entre le rail et la lame 1.FIG. 3 represents a fixing system such as that described in application 88 10759 but with the wedging device of the invention. The fixing system comprises in particular a clamping means 3 passing through the opening 4 made in the leaf spring 1 by removing the riblon 5 of material. Locking for example by screwing the clamping means 3 in the cross member 2 through the blade 1 allows the leaf spring 1 to be pressed against the pad 6 of the rail R. The front end 1A of the blade therefore comes into bearing contact on an insulating stop 9 interposed between the rail and the blade 1.
Pour éviter toute rotation de la lame 1 autour de l'axe du moyen de serrage 3, il est nécessaire de caler ladite lame.To avoid any rotation of the blade 1 around the axis of the clamping means 3, it is necessary to wedge said blade.
Ce calage est obtenu par des moyens de blocage et d'appui du talon arrière IR de la lame ressort 1 sur la traverse 2.This setting is obtained by means of blocking and supporting the rear heel IR of the leaf spring 1 on the crosspiece 2.
Selon l'invention, ces moyens de blocage et d'appui comprennent des saillies verticales 2D, 2G réalisées dans la masse de la traverse 2. Les saillies 2D, 2G définissent un logement 7 destiné à recevoir le riblon 5 de façon horizontale sur lequel le talon arrière IR de la lame 1 vient en contact d'appui. Les saillies 2D, 2G sont réalisées sur la traverse 2 parallèlement au rail R et forment un surbau contre lequel le bord extérieur 8 du talon arrière IR de la lame 1 vient en appui latéral de butée.According to the invention, these blocking and support means comprise vertical projections 2D, 2G made in the mass of the cross member 2. The projections 2D, 2G define a housing 7 intended to receive the riblon 5 horizontally on which the IR rear heel of blade 1 comes into bearing contact. The 2D, 2G projections are made on the cross member 2 parallel to the rail R and form a coarse edge against which the outer edge 8 of the rear heel IR of the blade 1 comes into lateral abutment abutment.
La plus grande dimension du riblon 5 (formé de la réunion de deux demi-cercles de diamètre 25 mm dont les centres sont distants de 5 mm, soit une surface d'environ 6 cm2) est inférieure à la largeur du talon arrière IR de la lame 1, qui est d'environ 70 mm. Le talon arrière IR est cambré et repose donc uniquement dans sa partie centrale et par sa tranche sur le riblon 5 qui joue à la fois le rôle de plaquette d'appui pour répartir la pression et de plaque de protection pour le matériau de la traverse 2.The largest dimension of the riblon 5 (formed by the union of two semicircles of 25 mm diameter whose centers are 5 mm apart, i.e. an area of approximately 6 cm2) is less than the width of the rear heel IR of the blade 1, which is about 70 mm. The rear heel IR is arched and therefore rests only in its central part and by its edge on the riblon 5 which plays both the role of a support plate for distributing the pressure and a protective plate for the material of the cross member 2 .
La lame 1 exerce approximativement sur le riblon 5 une force de 630 kg, ce qui correspond à une pression d'environ 105 kg/cm2 qui est tout-à-fait acceptable pour la traverse en béton sachant que le riblon 5 a une épaisseur d'environ 4 mm et une résistance à la rupture de l'ordre de 70 kg/mm2.The blade 1 exerts approximately on the riblon 5 a force of 630 kg, which corresponds to a pressure of approximately 105 kg / cm2 which is entirely acceptable for the concrete cross member knowing that the riblon 5 has a thickness d '' about 4 mm and a breaking strength of around 70 kg / mm2.
La réaction d'appui arrière de la lame 1 sur la traverse 2 est quasiment perpendiculaire au riblon 5. De ce fait, les saillies 2D, 2G ne subissent que peu d'effort et ne risquent pas d'être endommagées.The rear support reaction of the blade 1 on the cross-member 2 is almost perpendicular to the riblon 5. As a result, the projections 2D, 2G undergo only a little effort and are not likely to be damaged.
Le ribloa a donc toutes les qualités nécessaires et suffisantes pour remplir son rôle. Le logement 7 avec le riblon 5 est situé dans le plan de symétrie de la lame ressort 1. Les saillies 2D,2G permettent à la fois de positionner transversalement la lame ressort 1 par rapport au rail, en association avec les moyens de serrage 3 et d'empêcher toute rotation de la lame 1 autour de l'axe desdits moyens de serrage. The ribloa therefore has all the necessary and sufficient qualities to fulfill its role. The housing 7 with the riblon 5 is located in the plane of symmetry of the leaf spring 1. The projections 2D, 2G allow both to position transversely the leaf spring 1 relative to the rail, in association with the clamping means 3 and to prevent any rotation of the blade 1 around the axis of said clamping means.
