Abstract

L'invention concerne un appareil de freinage d'urgence pour train sur rails, un système de freinage d'urgence pour train sur rails et un train sur rails muni de l'appareil de freinage d'urgence pour train sur rails, celui-ci étant capable d'arrêter un train sur rails circulant à vitesse extrêmement élevée après qu'il a parcouru une distance prédéterminée en cas d'urgence, par exemple lorsqu'un obstacle, une personne ou une voiture se trouve devant le train sur rails dans la direction de son mouvement d'avance et lorsqu'un séisme s'est produit, la distance prédéterminée étant approximativement la même qu'une distance exigée conventionnellement en pareil cas. Dans un train (100) sur rails selon l'invention, chacune des voitures (201 à 206) est munie d'au moins un ou d'une pluralité de dispositifs (300 et 400) de moteurs à réaction. Une poussée émanant de ces dispositifs (300 et 400) de moteurs à réaction est générée dans la direction de mouvement d'avance des voitures (201 à 206) (direction indiquée par l'une quelconque des flèches (H1 et -H1)).
