Abstract

Des systèmes d'entraînement à réduction différentielle disposés de part et d'autre d'un véhicule sont mûs par deux vis sans fin (110) s'engrènant dans des roues à denture hélicoïdale (111), qui transmettent un couple de direction à chaque entraînement à réduction. Les roues à denture hélicoïdale sont reliées en rotation, de sorte que le couple de direction transmis aux entraînement à réduction est de valeur égale et opposée. De ce fait, un simple arbre de commande de direction (46) peut recevoir le couple de direction pour les man÷uvres de direction normales et le couple d'entraînement pour effectuer par pivotement des man÷uvres de virage assistées par l'entraînement. L'utilisation d'un frein pour les man÷uvres de direction, appliqué à la transmission recevant le couple d'entraînement, peut rendre précises les man÷uvres de direction par pivotement.
