Abstract

Un système dentraînement hydraulique amélioré est décrit pour un tracteur du type qui possède des roues à entraînement hydraulique à une extrémité cabine et des roues pivotantes à une extrémité moteur où chacune des roues entraînées est entraînée par un moteur hydraulique alimenté par un fluide provenant dune pompe qui possède un réglage par pas continu du déplacement. Le moteur est amélioré en fournissant un réglage par pas continu du déplacement du moteur. Le déplacement de moteur est contrôlé par un contrôleur électronique en réponse au mouvement du levier de commande de vitesse pour gérer le déplacement pour obtenir les couples dentraînement requis à différents points dans la course. Linvention propose un système de direction automatique qui possède une unité de commande de guidage placée pour recevoir des informations sur la position du GPS lequel contrôle la direction en réglant de manière différentielle le déplacement des moteurs de sorte que la direction automatique est indépendante de la direction manuelle laquelle commande les pompes.
