Abstract

Cette invention concerne un système de transmission auxiliaire pour véhicules ou engins automoteurs comportant des roues motrices et des roues pouvant être entraînées sélectivement. Il est prévu une pompe réversible à débit variable reliée aux moteurs hydrauliques des roues pouvant être entraînées de façon sélective, ainsi qu'un dispositif de commande de sens et de débit associé à la pompe. Un dispositif de commande du système d'entraînement auxiliaire est prévu entre ce dispositif de commande et la transmission principale et réagit à la condition de celle-ci pour commander la pompe, de telle sorte que les rotors des moteurs hydrauliques tournent à un régime représentant un pourcentage prédéterminé du régime moyen des roues motrices principales. Un agencement de ce type est utilisable notamment sur les niveleuses automotrices.
