Abstract

L'invention concerne une structure de montant central pour une automobile configurée de sorte qu'une partie de la partie inférieure d'un montant central (18), la partie connectée à un longeron latéral (17), est configurée en reliant un élément extérieur (22) et un élément intérieur (23). L'élément extérieur (22) est constitué d'aluminium ayant une haute résistance contre une charge de compression, et l'élément intérieur (23) est constitué de CFRP ayant une résistance élevée contre un effort de traction. Par conséquent, quand une charge de collision causée par une collision latérale est mise en œuvre et la partie inférieure du montant central (18) est déformée et pliée vers l'intérieur dans le sens de la largeur de l'automobile pour amener une charge de compression à agir sur l'élément extérieur (22) et aussi pour amener un effort de traction à agir sur l'élément intérieur (23), le montant central (18) a une résistance élevée car l'élément intérieur (23) a une résistance élevée contre une charge de compression et l'élément extérieur (22) a une résistance élevée contre un effort de traction. L'épaisseur de tôle de l'élément extérieur (22) et de l'élément intérieur (23) est réduite pour réduire le poids, et la déformation du montant central (18) lors d'une collision latérale peut être réduite au minimum.
