Abstract

L'invention concerne une transmission hydrostatique pour un engin mobile se déplaçant sur un terrain en pente et en dévers comprenant une pompe hydraulique (10), un premier essieu équipé de moteurs hydraulique gauche (20) et droit (30), un deuxième essieu équipé d'un moteur hydraulique double gauche (40) et droit (60), des liaisons hydrauliques (100, 110, 120, 130) a) entre un port de la pompe (10) et un port des moteurs (20, 30) du premier essieu et d'un premier moteur élémentaire (46, 66) des moteurs (40, 60) du deuxième essieu, b) entre un deuxième port de la pompe (10) et un second port des deux moteurs élémentaires (44, 46, 64, 66) des deux moteurs (40, 60) du deuxième essieu et c) en série entre les moteurs (20, 30) du premier essieu et un deuxième moteur élémentaire (44, 64) des moteurs (40, 60) du deuxième essieu, caractérisé par le fait qu'il comprend des restrictions (210, 220) commutables entre un état inactif et un état actif sur la liaison reliant la pompe hydraulique (10) respectivement au second port des deux moteurs (40, 60) du deuxième essieu et des moyens (UC) adaptés pour activer l'une des restrictions lorsque l'engin se déplace sur un terrain en dévers.
