Abstract

Dans une direction asservie pour véhicule à chenilles comprenant une pompe hydrostatique à huile 8, un moteur correspondant 10 et une unité d'entraînement hydrodynamique 14, on règle le débit spécifique d'entrée du moteur 10 en fonction de la caractéristique de l'unité hydrodynamique 14 de façon que lors de l'augmentation de la vitesse de cette dernière le débit du moteur 10 soit diminué et que par suite la vitesse de ladite unité 14 soit augmentée. A partir d'un certain couple exercé sur la direction, c'est l'effet de la pression qui prédomine pour assurer le réglage. Réduction au minimum possible des dimensions des organes.
