Abstract

L'invention propose un ensemble (10) de structure de caisse de véhicule automobile, comportant une partie (12) de structure de caisse formant compartiment moteur agencée en avant d'une cellule (14) ou habitacle du véhicule, du type dans lequel la partie (12) de structure de caisse comporte au moins deux longerons (16) sensiblement longitudinaux qui sont susceptibles de s'écraser longitudinalement partiellement, en cas de choc longitudinal, et du type comportant deux cloches (28) porteuses d'éléments de suspension du véhicule dont chacune est accolée transversalement à un longeron (16), caractérisé en ce que chaque longeron (16) comporte une zone (32) d'amorce de pliage agencée longitudinalement en avant de la cloche (28) qui permet, en cas de choc (F) longitudinal, qu'une partie avant (34) du longeron (16) se plie autour de la zone (32) d'amorce en laissant une partie arrière (36) du longeron et la cloche (28) sensiblement intactes.
