Abstract

La présente invention concerne un wagon porte-rails, qui comprend une voiture (20), la voiture (20) comprenant un avant (21) et un arrière (22), l'avant (21) et/ou l'arrière (22) étant recouverts d'un boîtier souple (3) équipé d'une structure de coussin d'air ; lorsque le boîtier souple (3) est dans l'état déplié, le wagon porte-rails présente une structure profilée dans son ensemble. Le wagon porte-rails est doté du boîtier souple (3) équipé de la structure de coussin d'air sur l'arrière (22) du wagon (20), par conséquent, lorsque n'importe quel wagon porte-rails fonctionne indépendamment, il présente une structure profilée présentant une faible résistance au vent, et lorsque de multiples wagons porte-rails sont raccordés bout à bout dans un train, un amarrage sans soudure peut être réalisé, ce qui réduit la résistance au vent du train, confère une résistance au vent inférieure au déplacement seul et réduit la consommation d'énergie des wagons porte-rails. De plus, lorsque le wagon porte-rails entre en collision, sous l'effet tampon du boîtier souple (3) dans l'état déplié, la force d'impact est efficacement ralentie et l'objectif de protection de la voiture (20) et des passagers est atteint.
