Abstract

The coupling is intended for railway cars of central buffer coupler type. It has two parallel carriers with a connecting bolt, suspended into the jaw of a draw hook. The coupling is held horizontally on both sides by a sprung lever system supported one side on the draw hook and hinged to the central buffer coupler on the other side. Between the carriers (2) there is a pressure member (11), with a face, facing the draw hook (4), cut-out in a trapezoidal shape. The draw hook protrudes into the cut-out (12) with a clearance. This provides a small angular free play between the transitional coupling and draw hook, and countercoupling impact aligns the transitional coupling axially to the draw hook.

Description

ATTELAGE DE RACCORDEMENT DESTINE PLUS
PARTICULIEREMENT AUX VEHICULES SUR RAILS.
CONNECTING HITCH FOR PLUS
PARTICULARLY FOR VEHICLES ON RAILS.

La présente invention a pour objet un attelage de raccordement, destiné plus particulièrement aux véhicules sur rails, constituant un attelage automatique à tampon central, présentant deux supports parallèles reliés l'un à l'autre par un boulon venant s accrocher dans l'ouverture d'un crochet de traction, et maintenu horizontalement de part et d'autre par une tringlerie comportant des leviers montés élastiquement et reposant d'une part sur le crochet de traction et articulés d'autre part sur l'attelage à tampon central. The subject of the present invention is a connection hitch, intended more particularly for rail vehicles, constituting an automatic hitch with central buffer, having two parallel supports connected to each other by a bolt which is hooked in the opening of 'a traction hook, and held horizontally on both sides by a linkage comprising levers mounted elastically and resting on the one hand on the traction hook and articulated on the other hand on the central buffer coupling.

Le brevet allemand 863 822 décrit un tel attelage de raccordement dont le fonctionnement est assuré complètement par un crochet de traction fixe. Or, l'utilisation internationale de crochets de traction articulés pivotants et la forme donnée à la pointe du crochet de traction font que le pivotement du crochet de traction peut provoquer un déplacement angulaire de l'attelage par rapport au crochet et qu'au moment de l'accouplement de l'attelage qui suit, il se produit sous l'action des poussées provenant du choc un déplacement angulaire supplémentaire d'où peuvent résulter des dommages aux articulations. German patent 863 822 describes such a connection hitch, the operation of which is completely ensured by a fixed traction hook. However, the international use of pivoting articulated traction hooks and the shape given to the tip of the traction hook mean that the pivoting of the traction hook can cause an angular displacement of the coupling relative to the hook and that at the time of the coupling of the coupling which follows, there occurs under the action of the thrusts coming from the shock an additional angular displacement from which can result in damage to the joints.

Le brevet allemand 957 850 décrit un attelage à tampon central comportant un bâti enserrant le crochet de traction par les deux côtés et par le fond et qui est maintenu en place par un dispositif sous tension pénétrant dans l'ouverture du crochet de traction
Avec une telle disposition des organes, les surfaces d'appui qui transmettent les forces de traction et de poussée entre l'attelage de raccordement et l'attelage opposé se trouve à la face inférieure du crochet de traction de telle sorte que l'on se trouve en présence

of a transmission of the shock with elastic bending of the coupling with central buffer on the frame, associated with a tilting traction hook has the additional result of the same drawbacks as those mentioned above.

L'invention se propose d'éliminer de tels inconvénients et d'établir une liaison entre l'attelage de raccordement et le crochet de traction,telle que les déplacements angulaires soient faibles et que la poussée exercée par l'attelage opposé rétablisse l'alignement axial de l'attelage de raccordement sur le crochet de traction. The invention proposes to eliminate such drawbacks and to establish a connection between the connecting coupling and the traction hook, such that the angular displacements are small and that the thrust exerted by the opposite coupling restores alignment. axial of the connection coupling on the traction hook.

Le problème ainsi posé est résolu par l'invention grâce à ce que l'on dispose entre les deux supports un appui dont la surface regardant le crochet de traction présen un évidement de forme trapézoidale dans lequel le crochet de traction pénètre avec un certain jeu. The problem thus posed is resolved by the invention thanks to the fact that there is between the two supports a support whose surface looking at the traction hook has a trapezoidal-shaped recess in which the traction hook penetrates with a certain clearance.

On a représenté aux dessins ci-joints une forme d'exécution de l'invention choisi à titre d'exemple. Sur ces dessins
La Fig. 1 est une vue latérale de l'attelage de raccordement avec coupe partielLe montrant le mode de suspension du crochet de traction.
The accompanying drawings show an embodiment of the invention chosen by way of example. On these drawings
Fig. 1 is a side view of the connection hitch with partial section showing the mode of suspension of the traction hook.

La Fig. 2 est une coupe suivant la ligne II-I I de la Fig. 1
L'attelage de raccordement représenté est constitué par un attelage à tampon central 1 dont l'extrémité arrière présente deux supports parallèles 2 semblables dirigés vers l'arrière et disposés de part et d'autre de l'axe de l'attelage avec un certain écartement entre eux. Les extrémités libres de ces supports sont reliées par un boulon d'accrochage 3 maintenant l'accouplement de raccordement dans l'ouverture du crochet de traction 4 qui peut pivoter autour d'une traverse solidaire du corps du véhicule concerné.De part et d'autre de l'attelage à tampon central 1 est monté un levier coudé 5 dont un bras télescopique coulissant 5a maintenu à son allongement maximum par un ressort de compression est articulé sur cet attelage à tampon central 1 tandis que les autres bras rigides 5b des deux leviers coudés sont reliés l'un à l'autre par une barre 6. Un écrou de réglage 7 est monté au milieu de cette barre 6 et commande une barrette 9 dont la face inférieure opposée à l'écrou 7 est évidée de manière à coiffer la pointe 8 du crochet de traction 9.Les leviers 5 disposés de part et d'autre de l'axe de l'attelage sont reliés par une broche 10 communs ras de levier 5a et 5b, cette broche 10 servant en même temps de surface d'appui pour la face avant du crochet de traction, de telle sorte que le réglage de la barrette 9 définit la position angulaire dans le plan vertical de l'attelage de raccordement par rapport au boulon 3 et par suite aussi la position moyenne de l'attelage.
Fig. 2 is a section along the line II-I I of FIG. 1
The connection coupling shown is constituted by a central buffer coupling 1 whose rear end has two similar parallel supports 2 directed towards the rear and arranged on either side of the axis of the coupling with a certain spacing between them. The free ends of these supports are connected by a fastening bolt 3 holding the connection coupling in the opening of the traction hook 4 which can pivot around a cross member secured to the body of the vehicle concerned. other of the central buffer coupling 1 is mounted a bent lever 5 of which a sliding telescopic arm 5a maintained at its maximum elongation by a compression spring is articulated on this central buffer coupling 1 while the other rigid arms 5b of the two levers bends are connected to each other by a bar 6. An adjustment nut 7 is mounted in the middle of this bar 6 and controls a bar 9 whose underside opposite the nut 7 is hollowed out so as to cover the tip 8 of the traction hook 9. The levers 5 arranged on either side of the axis of the hitch are connected by a common pin 10 flush with lever 5a and 5b, this pin 10 serving at the same time as surface d support for the front of the t hook reaction, so that the adjustment of the bar 9 defines the angular position in the vertical plane of the connecting hitch relative to the bolt 3 and therefore also the average position of the hitch.

Le bec 8 du crochet de traction présente en section de droite une partie à profil elliptique 8a le long de ses faces transversales et arrière et une partie 8b à profil en arc de cercle le long de sa face intérieure regardant l'ouverture du crochet ; ainsi, les deux cotés de la partie 8a s'étendent à une petite distance des supports 2 tandis que la partie 8b se trouve au contact du boulon d'accrochage 3 qui présente dans sa partie médiane un évidement annulaire pour recevoir cette partie 8b du bec. The spout 8 of the traction hook has, in cross-section, a part with an elliptical profile 8a along its transverse and rear faces and a part 8b with a profile in an arc along its inner face looking at the opening of the hook; thus, the two sides of the part 8a extend a small distance from the supports 2 while the part 8b is in contact with the fastening bolt 3 which has in its middle part an annular recess to receive this part 8b of the spout .

Entre les supports 2 est fixé un appui transversal horizontal 11 dont la partie arrière présente un évidement trapézoidal 12 dimensionné de telle manière que cet appui 11 se trouve à une petite distance de la face transversale avant du bec 8 du crochet en regard ainsi que d'une partie des faces latérales de ce bec. L'avant du bec 8 se trouve donc entouré par cet appui 11 avec du jeu, et par suite, en raison de la forme elliptique de la partie 8a du profil du bec 8, le jeu entre l'appui 11 et la face avant du bec est supérieur à celui séparant cet appui des faces latérales du bec. Between the supports 2 is fixed a horizontal transverse support 11 whose rear part has a trapezoidal recess 12 dimensioned in such a way that this support 11 is located a short distance from the front transverse face of the beak 8 of the hook opposite as well as part of the side faces of this beak. The front of the spout 8 is therefore surrounded by this support 11 with play, and consequently, due to the elliptical shape of the part 8a of the profile of the spout 8, the play between the support 11 and the front face of the beak is greater than that separating this support from the lateral faces of the beak.

La présence et la forme donnée à l'appui 11 ont pour premier résultat de réduire l'angle d'inflexion des supports par rapport au crochet de traction. De plus, on parvient ainsi à transmettre axialement au crochet de traction 4 les forces produites par le choc de l'attelage du raccordement au moment de l'accouplement.La raison en est qu'au moment de cet accouplement, L'attelage opposé repousse l'attelage de raccordement dans l'ouverture du crochet de traction 4.En même temps, le bec 8 du crochet est repoussé dans l'évidement 12 de l'appui 11 pendant cette pénétration du boulon 3 dans l'ouverture du crochet, grâce à quoi les faces latérales inclinées 12a de cet évidement 12 redressent l'attelage de raccordement qui se place dans l'axe du crochet de traction 4. Lorsque les faces avant et latérales du bec 8 se sont ainsi placées par rapport à l'appui 11, elles y sont maintenues au moment où se produit le choc proprement dit. Au cours de la marche des véhicules accouplés, les forces de traction ramènent l'attelage de raccordement à sa position permettant son pivooement et par suite, un parcours sans contrainte le long des courbes, les forces de compression rétablissant la position prescrite pour assurer aussi la transmission axiale des forces pendant la marche. The presence and the shape given to the support 11 have the first result of reducing the angle of inflection of the supports relative to the traction hook. In addition, we thus manage to transmit axially to the traction hook 4 the forces produced by the shock of the coupling hitch at the time of coupling. The reason is that at the time of this coupling, the opposite coupling repels the coupling coupling in the opening of the traction hook 4.At the same time, the beak 8 of the hook is pushed back into the recess 12 of the support 11 during this penetration of the bolt 3 into the opening of the hook, thanks to which the inclined lateral faces 12a of this recess 12 straighten the connecting hitch which is placed in the axis of the traction hook 4. When the front and lateral faces of the spout 8 are thus positioned relative to the support 11 , they are held there when the actual shock occurs. During the movement of the coupled vehicles, the traction forces bring the coupling hitch back to its position allowing its pivoting and consequently, an unconstrained course along the curves, the compression forces restoring the prescribed position to also ensure the axial transmission of forces during walking.
