Abstract

Le châssis de l'invention est constitué de quatre volumes longitudinaux, de manière qu'ils adoptent tous une place qui s'étend dans le véhicule, tout en définissant le volume principal comme cellule de sécurité, protégé par les autres trois volumes. Le second volume est destiné à loger l'ensemble de la motorisation-transmission (V2) et se place sous et à l'intérieur du volume (V1) ou habitacle, alors que latéralement de l'habitacle deux volumes latéraux se placent symétriquement, et longitudinalement (V3-V4) qui outre leurs fonctions de stockage, carènent ou intègrent d'autres pièces tels que les dépôts de combustible, des trains avants et arrières, etc. et agissent comme des éléments de sécurité face à tout type d'impacts, en les absorbant par des déformations programmées élastiques, au niveau de leurs pare-chocs périmétriques, et permanents au niveau de leurs quatre volumes, qui produisent des décélérations modérées. On accède au châssis par l'arrière, au moyen d'une porte qui s'appuie sur les volumes (V1 et V2).
