Abstract

cette invention concerne un essieu vectoriel hydraulique comprenant un différentiel entraîné par un arbre mu par un moteur et deux essieux entraînés par le différentiel. Le carter de différentiel est couplé à un élément d'un train d'engrenage épicycloïde, train d'engrenage dont un autre élément est relié à l'un des essieux et à un moteur hydrostatique. Le carter de différentiel est couplé à une pompe hydrostatique à cylindrée variable, laquelle est reliée hydrauliquement au moteur hydrostatique. Un système de commande gère la cylindrée de la pompe hydrostatique à cylindrée variable. La puissance provenant du moteur s'écoule pour l'essenteil du différentiel aux arbres de sortie. Le couple peut être transmis d'un essieu à l'autre par réglage sélectif de la cylindrée de la pompe de sorte qu'elle entraîne le moteur hydrostatique pour que la part de couple qu'il transmette à un essieu soit plus important que la part de couple transmis à l'autre essieu, la différence étant déterminée par le réglage de cylindrée de la pompe. La répartition requise du couple être les deux roues est déterminée par la commande de l'ordinateur à partir d'entrées de capteurs disposés dans le véhicule.
