Description

La présente invention concerne les dispositifs de liaison entre véhicules, notamment ferroviaires, constituant une rame articulée, en général, et porte, plus particulièrement, sur une articulation d'accouplement entre deux véhicules, notamment ferroviaires.The present invention relates to connection between vehicles, in particular rail, constituting an articulated oar, in general, and carries, more particularly on a coupling joint between two vehicles, notably rail vehicles.

Le document DE-AS-1 040 063 divulgue une articulation d'accouplement entre deux véhicules présentant une fonction de rotation et une fonction d'amortissement, chaque fonction de rotation et d'accouplement étant réalisé par des éléments distincts. Cependant une telle articulation présente l'inconvénient de ne pas permettre de débattements angulaires autour de l'axe longitudinal et n'est donc pas adaptée au véhicule pendulaire.Document DE-AS-1 040 063 discloses a joint coupling between two vehicles with a function of rotation and a damping function, each function of rotation and coupling being achieved by elements distinct. However, such a joint presents the disadvantage of not allowing angular deflections around the longitudinal axis and is therefore not suitable for tilting vehicle.

Le document EP-A-0 667 271 de la demanderesse décrit une articulation d'accouplement entre deux véhicules ferroviaires reposant sur un bogie médian entre lesdits deux véhicules ferroviaires, comprenant:

  • une pièce torique reliée à l'un des véhicules,
  • une pièce de support relié à l'autre véhicule,
  • un pivot cylindrique fixé sur une semelle et engagé dans un alésage cylindrique,
  • un élément d'articulation torique fixé sur ladite semelle assurant l'articulation entre ladite semelle et ladite pièce torique.
Document EP-A-0 667 271 by the applicant describes a coupling articulation between two railway vehicles resting on a median bogie between said two railway vehicles, comprising:
  • an O-ring connected to one of the vehicles,
  • a support piece connected to the other vehicle,
  • a cylindrical pivot fixed on a sole and engaged in a cylindrical bore,
  • a toric articulation element fixed on said sole ensuring articulation between said sole and said toric part.

Un élément d'articulation torique assure l'articulation entre une semelle et la pièce torique.A toric joint element ensures the joint between a soleplate and the O-ring.

Cet élément d'articulation torique est une structure composée de couches successives et multiples en métal et en caoutchouc pouvant être de rigidités différentes et progressives.This toric joint element is a structure composed of successive and multiple layers of metal and rubber which may be of different stiffnesses and progressive.

Un inconvénient majeur de l'articulation d'accouplement de deux véhicules ferroviaires décrite dans ce document de l'art antérieur est qu'il ne permet que de faibles débattements angulaires.A major drawback of the joint coupling of two railway vehicles described in this prior art document is that it only allows low angular deflections.

Dans le cas particulier des véhicules pendulaires, l'articulation d'accouplement de deux véhicules ferroviaires décrite dans ce document de l'art antérieur ne permet pas de supporter le débattement autour de l'axe longitudinal sans produire un effort de retenue.In the particular case of tilting vehicles, the coupling joint of two railway vehicles described in this document of the prior art does not allow support the deflection around the longitudinal axis without produce a restraining effort.

Cet effort de retenue a pour inconvénient fondamental d'imposer une torsion de caisse.This restraint effort has the fundamental disadvantage to impose a body twist.

L'articulation d'accouplement de deux véhicules ferroviaires décrite dans ce document de l'art antérieur a comme inconvénient d'être rigide et donc d'imposer un vrillage des caisses des véhicules à pendulation lors du passage de voies en courbe.The coupling joint of two vehicles railway described in this document of the prior art has as a disadvantage of being rigid and therefore of imposing a twisting of tilting vehicle bodies during passage of curved tracks.

Aussi un but de l'invention est-il une articulation d'accouplement de deux véhicules, notamment ferroviaires, supportant le débattement autour de l'axe longitudinal sans produire un effort de retenue afin d'éviter toutes torsions de caisse.Also an object of the invention is a joint coupling of two vehicles, especially rail vehicles, supporting the deflection around the longitudinal axis without produce a restraining force in order to avoid any twists checkout.

  • des éléments élastiques prenant appui contre la surface extérieure du second élément de la rotule,
  • un disque en appui sur les éléments élastiques et relié au châssis de la caisse de l'autre véhicule.
In accordance with the invention, the coupling articulation between two vehicles, in particular railway vehicles, resting on a median bogie between said two vehicles, said coupling articulation having a rotation function and a damping function, each rotation function and depreciation being carried out by separate elements, is characterized in that it comprises:

  • la pièce torique centrale est évidé dans sa partie inférieure afin de recevoir l'entraínement caisse/bogie.
The coupling joint of the invention also satisfies at least one of the following characteristics:

Conformément à une caractéristique essentielle, l'articulation d'accouplement entre deux véhicules A, B, notamment ferroviaires, reposant sur un bogie médian (non représenté) entre les deux véhicules et présentant une fonction de rotation et une fonction d'amortissement, est telle que chaque fonction de rotation et d'amortissement est réalisé par des éléments distincts.In accordance with an essential characteristic, the coupling joint between two vehicles A, B, especially rail, resting on a middle bogie (not shown) between the two vehicles and presenting a rotation function and a damping function, is such that each rotation and damping function is made by separate elements.

Comme représenté aux figures 1 à 3, l'articulation d'accouplement comporte une pièce torique centrale 3, présentant une surface d'appui tronconique 3A, une rotule 1, 2 comportant une partie conique centrale creuse 1A s'imbriquant sur la surface d'appui tronconique 3A de la pièce torique centrale 3, des éléments élastiques 4, un disque 5 et une vis de maintien 6 comportant un pivot vertical 6A.As shown in Figures 1 to 3, the joint coupling comprises a central toric part 3, having a frustoconical bearing surface 3A, a ball joint 1, 2 having a hollow central conical part 1A nesting on the frustoconical bearing surface 3A of the central O-ring 3, elastic elements 4, a disc 5 and a retaining screw 6 comprising a pivot vertical 6A.

La pièce torique centrale 3 comporte en partie supérieure la surface d'appui tronconique 3A et est reliée par sa partie inférieure au châssis 9 de la caisse de l'un des véhicules B.The central toric part 3 partly comprises the tapered support surface 3A and is connected by its lower part to the chassis 9 of the body of one vehicles B.

La rotule 1, 2 associe un premier élément 1 de forme générale sphérique à un second élément 2 externe disposé libre en rotation sur le premier élément 1.The ball 1, 2 combines a first element 1 of shape general spherical to a second external element 2 arranged free to rotate on the first element 1.

Les éléments élastiques 4 sont, de préférence au nombre de deux, de forme générale semi-circulaire et sont disposés symétriquement de part et d'autre de la rotule 1, 2 et de l'axe longitudinal du véhicule de manière à prendre appui contre la surface extérieure du second élément 2 de la rotule 1, 2. The elastic elements 4 are, preferably at number of two, generally semicircular and are symmetrically arranged on either side of the ball 1, 2 and the longitudinal axis of the vehicle so as to take support against the external surface of the second element 2 of the ball 1, 2.

Le disque 5 est disposé entre le châssis 9 de la caisse de l'un des véhicules B et une pièce de support 12 de l'articulation d'accouplement.The disc 5 is disposed between the chassis 9 of the body of one of the vehicles B and a support piece 12 of the coupling joint.

Le disque 5 maintien le second élément 2 de la rotule 1, 2 sur le premier élément 1 de la rotule 1, 2.The disc 5 holds the second element 2 of the ball joint 1, 2 on the first element 1 of the ball joint 1, 2.

La vis de maintien 6 évite tout déboítement de l'ensemble, par exemple, lors du passage sur de gros défaut de voie.The retaining screw 6 avoids any dislocation of the whole, for example, when going over a big defect of track.

Un capot de protection supérieure 7 et une collerette inférieure 8 évite toutes projections, par exemple de ballast, pouvant détériorer l'articulation d'accouplement.A top protective cover 7 and a flange lower 8 avoids all projections, for example of ballast, which could damage the coupling joint.

Le disque 5 est relié au châssis 10 de la caisse de l'autre véhicule A.The disc 5 is connected to the chassis 10 of the body of the other vehicle A.

Le disque 5 est indéformable et l'une et l'autre de ses extrémités forme un buttoir.Disc 5 is non-deformable and both its ends form a ridger.

Les éléments élastiques 4 disposés symétriquement de part et d'autre de la rotule 1, 2 et de l'axe longitudinal du véhicule absorbent l'énergie en assurant une grande souplesse longitudinale. The elastic elements 4 arranged symmetrically on either side of the ball 1, 2 and the longitudinal axis of the vehicle absorb energy by ensuring high longitudinal flexibility.

Les éléments élastiques 4 présentent une grande rigidité transversale.The elastic elements 4 have a large transverse rigidity.

Cette absorption d'énergie se fait dans le sens longitudinal du véhicule plus particulièrement lors des tractions-freinages et accostages et évite tout risque de matage de la rotule 1, 2.This energy absorption is done in the direction longitudinal of the vehicle more particularly during traction braking and docking and avoids any risk of matting of the patella 1, 2.
