Abstract
Circuit hydraulique de commande de l'entraînement et de la direction d'un véhicule sur chenilles. Il comprend deux transmissions hydrostatiques associées chacune à une chenille, et un dispositif de commande qui, pour une première chenille, assume une fonction de commande principale et, pour l'autre chenille, une fonction de commande asservie. Le circuit est cependant sensible à des signaux produits par un dispositif manuel de commande de direction. Domaine d'application: véhicules à chenilles.
