Abstract

L'invention concerne une structure de véhicule comprenant un brancard comprenant deux longerons (1) en forme de profilés creux et une poutre transversale (2) portée par les extrémités avant de ces longerons (1), dans laquelle la poutre transversale (2) est solidaire, à chacune de ses extrémités, d'un piston (21) s engageant dans un tube de guidage (12) fixé dans la partie avant du longeron (1) correspondant et pouvant coulisser à force dans ce tube de guidage (12), la largeur du piston (21) étant inférieure à la largeur intérieure du longeron (21), de façon que la partie avant du longeron (1) puisse se déformer par compression longitudinale, lors d'un choc frontal du véhicule appliqué à la poutre transversale (2), en créant des plis de déformation, notamment vers intérieur, aux parois du profilé creux, et entrant en contact avec le piston (21) pour guider la compression longitudinale.The invention relates to a vehicle structure comprising a stretcher comprising two side members (1) in the form of hollow sections and a transverse beam (2) carried by the front ends of these side members (1), in which the transverse beam (2) is integral, at each of its ends, with a piston (21) engaging in a guide tube (12) fixed in the front part of the corresponding spar (1) and able to slide by force in this guide tube (12), the width of the piston (21) being less than the internal width of the side member (21), so that the front part of the side member (1) can be deformed by longitudinal compression, during a frontal impact of the vehicle applied to the transverse beam (2), by creating deformation folds, in particular towards the interior, at the walls of the hollow section, and coming into contact with the piston (21) to guide the longitudinal compression.
