Description

COUPLEUR-TAMPON CENTRAL A DISPOSITIF DE
PROTECTION, POUR VEHICULE FERROVIAIRE
La présente invention concerne un coupleur-tampon central, muni d'un dispositif de protection, pour véhicule ferroviaire.CENTRAL BUFFER COUPLER WITH DEVICE
PROTECTION, FOR RAIL VEHICLE
The present invention relates to a central buffer coupler, provided with a protection device, for a railway vehicle.

On connaît de EP-B-O 344 394, un dispositif de protection pour des véhicules ferroviaires munis de coupleur tampons centraux, ce dispositif de protection devant assurer sur toute la largeur frontale du véhicule une protection contre les chocs latéraux. Comme le dispositif de protection ne peut être monté sur le dispositif de traction et de choc qu a l'emplacement de la tête de coupleur amovible, on assure une protection qu'a une extrémité non couplable d'un véhicule ferroviaire. Pour le couplage, à un autre véhicule ferroviaire, le dispositif de protection doit être enlevé ou écarté, ce qui est très fréquent et fait que l'on n'assure également pas de protection dans la zone du coupleur-tampon central. EP-B-O 344 394 discloses a protection device for railway vehicles provided with central buffer couplers, this protection device having to provide protection against the side impact over the entire front width. As the protection device can only be mounted on the traction and shock device at the location of the removable coupler head, protection is provided only at a non-couplable end of a railway vehicle. For coupling to another rail vehicle, the protection device must be removed or removed, which is very frequent and means that protection is also not provided in the area of the central buffer coupler.

L'un des buts de la présente invention consiste précisément à proposer un dispositif de protection pour un coupleurtampon central et qui assure également pour les véhicules ferroviaires accouplables ou accouplés, une protection dans la zone du dispositif de traction et de choc, sans nécessiter d'équipements supplémentaires. One of the aims of the present invention consists precisely in proposing a protection device for a central buffer coupler and which also provides for couplable or coupled railway vehicles, protection in the area of the traction and shock device, without requiring additional equipment.

A cet effet, selon l'invention le dispositif de protection comporte des étriers de protection disposés des deux côtés d'une tête de coupleur du coupleur-tampon central. To this end, according to the invention, the protection device comprises protective stirrups arranged on both sides of a coupler head of the central buffer coupler.

Chaque étrier de protection est fixé de façon articulée à la tête de coupleur et est relié de façon articulée par une barre d'appui au châssis du véhicule ferroviaire. La tête de coupleur est montée sur une barre de traction-compression fixé de façon axialement mobile et pivotante sur le châssis.Each protective stirrup is hingedly attached to the coupler head and is hingedly connected by a support bar to the chassis of the rail vehicle. The coupler head is mounted on a tension-compression bar fixed axially mobile and pivoting on the chassis.

Selon un autre mode de réalisation de l'invention, les étriers de protections sont disposés dans un plan horizontal, dans laquelle se débat la barre de traction-compression. Les étriers de protection et les barres d'appui comportent, à leurs points d'articulation, des articulations permettant des déplacements de pivotement et longitudinaux de la tête de coupleur. According to another embodiment of the invention, the protection stirrups are arranged in a horizontal plane, in which the tension-compression bar struggles. The protective stirrups and the support bars have, at their articulation points, articulations allowing pivoting and longitudinal displacements of the coupler head.

Selon encore un autre mode de réalisation de l'invention, les articulations disposées sur les étriers de protection sont réalisés sous la forme de manchons d'articulation. According to yet another embodiment of the invention, the articulations arranged on the protective stirrups are produced in the form of articulation sleeves.

Les barres d'appui peuvent être élastiques et/ou aptes à absorber de l'énergie.The grab bars can be elastic and / or able to absorb energy.

D'autres buts, avantages et caractéristiques apparaîtront à la lecture de la description d'un mode de réalisation de l'invention, faite à titre non limitatif, et en regard du dessin annexé dans lequel la figure unique représente en vue de dessus, un coupleur-tampon central à dispositif de protection, pour un véhicule ferroviaire. Other objects, advantages and characteristics will appear on reading the description of an embodiment of the invention, given without limitation, and with reference to the appended drawing in which the single figure represents a top view, a central buffer coupler with protection device, for a railway vehicle.

Un coupleur-tampon central 1 comporte une tête de coupleur 3 disposée sur une barre de traction-compression 2. A central buffer coupler 1 comprises a coupler head 3 disposed on a tension-compression bar 2.

Cette barre de traction-compression 2 est reliée à un dispositif de tamponnement ou d'amortissement 4 agissant à la traction et à la compression et qui est fixé, pivotant dans la direction horizontale, sur le châssis 6 d'un véhicule ferroviaire, à l'aide d'une articulation tournante 5. La ligne 7 indique le contour extérieur de la caisse du véhicule ferroviaire.This traction-compression bar 2 is connected to a buffering or damping device 4 acting on traction and compression and which is fixed, pivoting in the horizontal direction, on the chassis 6 of a railway vehicle, at the using a rotary joint 5. Line 7 indicates the exterior contour of the body of the rail vehicle.

Un dispositif de protection 8 est monté sur le coupleurtampon central 1 et est susceptible de pivoter avec celui-ci. A protection device 8 is mounted on the central buffer coupler 1 and is capable of pivoting with the latter.

Le dispositif de protection 8 comporte des étriers de protection 9 qui sont disposés des deux côtés de la tête de coupleur 3 et qui sont reliés au châssis 6 par des barres d'appui 10. Ces barres d'appui peuvent présenter des propriétés d'élasticité ou bien être aptes à absorber de l'énergie.The protective device 8 comprises protective stirrups 9 which are arranged on both sides of the coupler head 3 and which are connected to the chassis 6 by grab bars 10. These grab bars can have elasticity properties or be able to absorb energy.

Le contour extérieur Il des étriers de protection 9, est sensiblement analogue au contour 7 de la caisse du véhicule et est disposé, au moins, en position médiane, à l'extérieur de la caisse du véhicule ferroviaire. The outer contour Il of the protective stirrups 9, is substantially similar to the contour 7 of the vehicle body and is arranged, at least, in the middle position, outside the body of the rail vehicle.

La tête de coupleur 3 comporte de chaque côté une patte 12 laquelle est fixée, de façon articulée, l'un distincte des étriers de protection 9, la liaison étant avantageusement réalisé à l'aide d'un manchon d'articulation à élastomère 13 autorisant des mouvements de pivotement limités. On peut également utiliser d'autres liaisons ou manchons d'articulation. Les barres d'appui 10 sont également reliées aux étriers de protection 9 à l'aide de manchons d'articulation 13 - de préférence avec des manchons d'articulation à élastomères 13 - l'emplacement d'articulation étant de préférence disposé dans la deuxième moitié de l'étrier de protection 9 de forme arquée. L'autre extrémité des barres d'appui 10 est reliée par des articulations de rotative 14 au châssis 6 du véhicule ferroviaire. The coupler head 3 comprises on each side a lug 12 which is fixed, in an articulated manner, one distinct from the protective stirrups 9, the connection being advantageously made using an elastomer articulation sleeve 13 allowing limited pivoting movements. It is also possible to use other links or articulation sleeves. The support bars 10 are also connected to the protective stirrups 9 using articulation sleeves 13 - preferably with elastomeric articulation sleeves 13 - the articulation location being preferably arranged in the second half of the arched protective stirrup 9. The other end of the support bars 10 is connected by rotary hinges 14 to the chassis 6 of the rail vehicle.

Afin d'absorber les chocs, l'étrier de protection 9 est avantageusement réalisé, par exemple, en forme de L ou de U et il peut également comporter sur le contour extérieur 11 une paroi de protection s'étendant vers le bas. In order to absorb shocks, the protective stirrup 9 is advantageously made, for example, in the shape of an L or a U and it can also have on the outer contour 11 a protective wall extending downwards.

Grâce à l'agencement articulé du dispositif de protection 8 sur le coupleur-tampon central 1, les étriers de protection 9 peuvent accompagner les déplacements longitudinaux de la tête de coupleur 3 apparaissant au cours des charges de compression ou de traction et également accompagner leurs déplacements de pivotement, par exemple en virage, et ceci sans risquer des coincements et en maintenant l'effet de protection. Thanks to the articulated arrangement of the protection device 8 on the central buffer coupler 1, the protective stirrups 9 can accompany the longitudinal movements of the coupler head 3 appearing during compression or traction loads and also accompany their movements pivoting, for example when cornering, and this without risking jamming and maintaining the protective effect.

Le dispositif de protection 8 est conçu pour absorber les chocs se produisant latéralement sur la tête de coupleur 3, la plus grande partie de l'énergie de choc étant absorbée par le dispositif de tamponnement ou d'amortissement 4 du coupleur-tampon central 1. The protection device 8 is designed to absorb the shocks occurring laterally on the coupler head 3, most of the impact energy being absorbed by the buffering or damping device 4 of the central buffer coupler 1.

On peut, en outre, protéger l'espace situé en dessous de la caisse du véhicule ferroviaire, pour autant que l'on installe dans cette zone une protection contre les objets ou les êtres vivants susceptibles de parvenir sous le véhicule ferroviaire.  It is also possible to protect the space located below the body of the rail vehicle, provided that protection is installed in this zone against objects or living beings liable to reach under the rail vehicle.

Bien entendu, la présente invention n'est pas limitée aux modes de réalisation décrits et représentés mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art sans que l'on ne s'écarte de l'esprit de l'invention.  Of course, the present invention is not limited to the embodiments described and shown but it is capable of numerous variants accessible to those skilled in the art without departing from the spirit of the invention.
