Abstract

WAGON ET MÉCANISME DE PORTE CONNEXE Abrégé : Une sortie de décharge de wagon-trémie est commandée par des éléments de fermeture, dont au moins un est mobile. Les éléments de fermeture (les portes) sont sans charnière, étant montés sur quatre liaisons de barre, de telle sorte que le bord distal des portes balaye principalement horizontalement tandis que le bord proximal de la porte se déplace principalement vers le haut. Les portes se déplacent à travers des arcs non circulaires, de telle sorte que la taille de louverture de porte projetée verticalement est anormalement grande par rapport aux hauteurs de dégagement de la porte lors de louverture et de la fermeture. Les portes sont entraînées par un mécanisme de commande transversal entraîné par un actionneur installé de manière transversale. Lactionneur peut être installé dans un espace protégé du vent des feuilles courbées entre les trémies adjacentes dans une partie intermédiaire du wagon. Lentraînement de lactionneur est porté à une paire de portes installées symétriquement au moyen des mécanismes de commande. Date reçue/Date Received 2020-04-15
