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.This invention relates to an auxiliary transmission system for vehicles or self-propelled machinery comprising drive wheels and wheels which can be selectively driven. A reversible variable flow pump connected to the hydraulic motors of the wheels which can be selectively driven, as well as a direction and flow control device associated with the pump, is provided. A control device for the auxiliary drive system is provided between this control device and the main transmission and reacts to the condition thereof to control the pump, so that the rotors of the hydraulic motors rotate at a speed representing a predetermined percentage of the average speed of the main drive wheels. An arrangement of this type can be used in particular on self-propelled graders.
