Definitions

  • the present invention relates, in general, to a connecting seal assembly for railway carriages, and more particularly to a connecting seal assembly for railway carriages which constitutes a connecting corridor positioned between two railway carriages and which is comprised of an integral rubber structure having a certain thickness or more to facilitate its manufacturing and installing processes.
  • a railway train is comprised of a plurality of carriage parts and adapted to travel on rails.
  • a comiecting corridor positioned between the carriage parts is adapted to enable railway carriages to travel on curved rails without trouble, and is provided with a gangway allowing passengers and traimnen to pass therethrough.

  • a bottom plate constituting the comiecting corridor is integrally joined to or separately manufactured and then connected to a mechanical structure connecting railway carriages. Moreover, since the bottom plate is mostly made of a rigid iron plate, the bottom plate may generate intensive metal frictional noise due to its vibration. Accordingly, such metal frictional noise generated from the bottom plates is transmitted to passenger rooms during opening and closing of doors of the rooms, thereby making passengers and trainmen uncomfortable and thus hindering a comfortable journey.

Abstract

L'invention a pour objet de fournir un ensemble joint de connexion destiné aux wagons ferroviaires. Cet ensemble joint de connexion (1) comprend un premier joint de connexion (10) qui est réalisé en caoutchouc dur, est couplé à deux wagons ferroviaires (2, 2') et forme le fond d'une voie permettant au conducteur et aux passagers de marcher le long de l'ensemble joint de connexion (1) lorsqu'ils se déplacent d'un wagon à un autre. Cet ensemble joint comprend un deuxième ensemble joint (20) qui est réalisé en caoutchouc souple, a la forme d'un soufflet, est intégré aux bords du premier joint de connexion (10) et est connecté par ses extrémités aux extrémités opposées des deux wagons (2, 2'). Ainsi l'ensemble joint de connexion (1) a une structure intégrée d'une épaisseur prédéterminée. Il est facile à produire et à installer sur les wagons, sans compter qu'il absorbe efficacement le bruit et empêche l'introduction d'air atmosphérique dans l'ensemble joint.
