CA 2728040

Improved trailers (e.g., semi-trailers) are disclosed. The trailers (100) include a floor (110) having a top surface (112) and a bottom surface (114), where the top surface is adapted to transport a payload, and an elongated shell (120) connected to the bottom surface of the floor, where the elongated shell defines a portion of a substantially closed torsion-resistant chamber of the trailer. The trailers may have a torsion resistance that is substantially higher than conventional trailers of similar size and/or load capacity. The trailers may weigh substantially less than conventional trailers of similar size and/or load capacity. The trailers may realize a bending resistance that is at least equivalent to the bending resistance of conventional trailers of similar size and/or load capacity.

L'invention porte sur des remorques améliorées (par exemple, des semi-remorques). Les remorques (100) comprennent un plancher (110) ayant une surface supérieure (112) et une surface inférieure (114), la surface supérieure étant apte à transporter une charge utile, et une enveloppe allongée (120) reliée à la surface inférieure du plancher, l'enveloppe allongée définissant une partie d'une chambre sensiblement fermée et résistant à la torsion de la remorque. Les remorques peuvent avoir une résistance à la torsion qui est sensiblement plus élevée que celle des remorques classiques de taille analogue et/ou de capacité de chargement analogue. Les remorques peuvent peser sensiblement moins que les remorques classiques de taille et/ou de capacité de chargement analogues. Les remorques peuvent avoir une résistance à la flexion qui est au moins équivalente à la résistance à la flexion des remorques classiques de taille et/ou capacité de chargement analogues.
