La partie du bogie 6 situé d'un côté arrière de l'axe de pivot A est situé entièrement sous le fond avant 32 de la caisse 4. La partie du bogie 6 s'étendant à l'avant de l'axe de pivot A s'étend d'abord sous le fond avant 32, puis sous le passage de circulation 16 et s'étend enfin partiellement sous le fond arrière 34 de la voiture 2 précédente. L'essieu 38 situé le plus à l'avant s'étend sensiblement au niveau de l'extrémité arrière de cette voiture 2 précédente.The part of the
On voit sur la
Verticalement, la liaison rotule 14 est interposée entre le bogie 6 et le plancher du passage de liaison 16 et plus précisément entre l'essieu avant 38 et le plancher du passage de liaison 16.Vertically, the ball joint 14 is interposed between the
La liaison rotule 14 est disposée à un niveau vertical inférieur ou égal à celui des moyens de liaison pivot 8 par rapport au plan de roulement de la rame.The ball joint 14 is arranged at a vertical level less than or equal to that of the pivot connection means 8 relative to the running surface of the train.
La rotule 70 de la liaison rotule 14 est disposée longitudinalement à une distance inférieure à deux mètres de l'axe A des moyens de liaison pivot 8, et de préférence est située à un mètre de l'axe A de la liaison pivot 8.The
La rame peut comprendre une voiture 2 pourvue d'un bras pantographe 76 monté sur le toit de la caisse 4, ce bras pantographe 76 étant avantageusement disposé à une extrémité avant de ce toit, au droit de l'axe A des moyens de liaison pivot 8.The train may include a car 2 provided with a
La rame de train décrite ci-dessus présente de multiples avantages.The train set described above has many advantages.
La liaison rotule 14 articulant une voiture 2 à la voiture précédente est décalée vers l'avant par rapport aux moyens de liaison pivot 8 de cette voiture 2 sur son bogie 6. Par ailleurs, la liaison rotule 14 est disposée à un niveau inférieur ou égal à celui des moyens de liaison pivot. Il est ainsi possible de disposer le plancher du passage 16 verticalement au même niveau que le plancher du volume intérieur 18 de la voiture 2.The ball joint 14 articulating a car 2 to the previous car is offset forwards with respect to the pivot connection means 8 of this car 2 on its
Dans l'état de la technique antérieure, le plancher du passage de circulation 16 était disposé plus haut que le plancher de la partie centrale du volume intérieur 18 de la voiture, car la liaison rotule était disposée au-dessus des moyens de liaison pivot, et sous le passage de circulation, comme on le voit sur la
Ce nouvel agencement de la liaison rotule 14 et des moyens de liaison pivot 8 permet d'abaisser le niveau du plancher du passage de circulation 16 d'environ 125 mm par rapport à l'état de la technique antérieure.This new arrangement of the ball joint 14 and of the pivot connection means 8 makes it possible to lower the level of the floor of the
Il est possible de créer ainsi un plancher de niveau égal le long de toutes les voitures de la rame, de telle sorte qu'un passager passant d'une voiture à une autre ne rencontre plus de dénivellation.It is thus possible to create a floor of equal level along all the cars of the train set, so that a passenger passing from one car to another no longer experiences a drop.
Il est à noter que le fait de dissocier la liaison rotule de la liaison pivot permet de réduire l'encombrement latéral des voitures dans les courbes. Pour une largeur transversale de voiture déterminée, la voiture fera saillie latéralement par rapport aux rails sur une distance plus faible quand elle parcourt une courbe.It should be noted that the fact of dissociating the ball joint from the pivot link makes it possible to reduce the lateral bulk of the cars in curves. For a determined car transverse width, the car will protrude laterally from the rails a shorter distance as it travels around a curve.
Selon un autre aspect, pour un encombrement transversal maximal déterminé en courbe, il est possible d'augmenter la largeur transversale de la caisse. Pour un décalage d'un mètre entre la liaison rotule et les moyens de liaison pivot, il est possible de gagner environ 35 mm sur la largeur de la caisse.According to another aspect, for a maximum transverse bulk determined in a curve, it is possible to increase the transverse width of the body. For an offset of one meter between the ball joint and the pivot connection means, it is possible to save about 35 mm over the width of the body.
Par ailleurs, du fait que les moyens de liaison pivot 8 sont disposés sous la partie avant de la caisse 4, il est possible d'implanter le bras pantographe 76 verticalement au droit des moyens de liaison pivot 8. Cette disposition permet de simplifier le débattement du bras pantographe par rapport à la caténaire 78.Furthermore, due to the fact that the pivot connection means 8 are arranged under the front part of the
Enfin, le fait que les moyens de liaison pivot 8 soient disposés sous la partie avant de la caisse et non plus sous le passage de circulation 16 permet que les amortisseurs 42 soient directement en appui sur le fond avant 32 de la caisse 4.Finally, the fact that the pivot connection means 8 are arranged under the front part of the body and no longer under the
La rame de train décrite ci-dessus peut présenter de multiples variantes sans sortir du cadre de l'invention.The train set described above can have multiple variants without departing from the scope of the invention.
Ainsi, alternativement, une dénivellation est formée entre le plancher du volume intérieur de la caisse et le plancher de passage de circulation, en baissant conjointement les niveaux des deux planchers. Ceci permet de réduire la hauteur des marches permettant d'accéder à l'intérieur de la caisse à partir du quai.Thus, alternatively, a difference in level is formed between the floor of the interior volume of the body and the circulation passage floor, jointly lowering the levels of the two floors. This makes it possible to reduce the height of the steps allowing access to the interior of the body from the dock.
En variante, la liaison rotule 14 entre une voiture et la voiture qui la précède est disposée sous le fond arrière 34 de la voiture avant plutôt que sous le plancher du passage de circulation mettant en communication les deux voitures.As a variant, the ball joint 14 between a car and the car in front of it is arranged under the
Le bogie 6 d'une voiture 2 peut ne pas être lié au fond avant 32 de la caisse 4, mais plutôt au fond arrière 34 de cette caisse. Dans ce cas, l'extrémité avant de la voiture 2 est supportée par l'extrémité arrière de la voiture qui la précède par l'intermédiaire de la liaison rotule 14.The
L'invention s'applique également aux rames de train articulées dans lesquelles chaque voiture 2 est pourvue de deux bogies 6, un bogie 6 situé sous le fond avant 32 de la caisse 4 et un bogie 6 situé sous le fond arrière 34 de la caisse 4. Dans ce cas, la liaison rotule 14 a seulement pour fonction d'articuler une extrémité d'une voiture 2 avec l'extrémité de la voiture 2 précédente, mais n'a plus pour fonction de supporter l'extrémité d'une des voitures.The invention also applies to articulated train sets in which each car 2 is provided with two
La rame de train décrite ci-dessus peut être à propulsion électrique ou thermique.The train set described above can be electric or thermal propulsion.
La voiture pourvue d'une liaison rotule 14 surbaissée par rapport à sa liaison pivot 8 peut être motorisée (motrice) ou non motorisée. La motrice peut être disposée à l'extrémité de la rame ou en position intermédiaire, entre deux voitures non motorisées. The car provided with a ball joint 14 lowered relative to its
