Abstract

a. Dispositif pour réduire la résistance de l'air sur un camion. b. Dispositif caractérisé en ce que l'appui 2 est de longueur constante, et que pour modifier l'inclinaison de l'écran déflecteur de vent 1, cet appui est susceptible de coulisser dans une fente longitudinale 6 s'étendant tangentiellement par rapport au toit 3 de la cabine du conducteur, un ressort de torsion 5 étant prévu au voisinage des paliers de pivotement 4a, 4b pour compenser le poids de l'écran déflecteur de vent, et un moyen de blocage avec un blocage par excentrique 11 étant prévu dans la fente longitudinale pour fixer l'appui. c. L'invention s'applique notamment aux camions à profil de chargement variable.
