Patent

CA 2007749

A vehicle body, such as, for example, a railway passenger vehicle body, which includes an external body sheeting formed of opposite sides and a roof and having an internal floor extending between the sides. The sides, above the level of the internal floor, and the roof each include a number of extruded metal plates forming the external body sheeting and integral ribs, extending in a longitudinal direction of the vehicle body, are provided on inner faces of the extruded metal plates. The extruded metal plates are welded together at weld lines extending in a longitudinal direction of the vehicle body.

L'invention vise une caisse de véhicule, comme, par exemple, une caisse de voiture pour le transport ferroviaire de personnes, qui comprend une enveloppe extérieure formée de parois latérales, d'un toit et d'un plancher intérieur entre les deux parois latérales. Lesdites parois, au-dessus du niveau du plancher intérieur, ainsi que le toit comportent un certain nombre de plaques de métal extrudé qui forment la caisse extérieure; des côtes intégrées, dans le sens longitudinal de la caisse, forment les faces intérieures des plaques de métal extrudé. Les plaques de métal extrudé sont soudées selon des lignes de soudure correspondant à l'axe longitudinal de la caisse.
