Abstract

Dispositif à engrenage différentiel pour l'unité d'entraînement d'arbre transversal d'un véhicule à chenilles, ce dispositif étant constitué par un engrenage planétaire différentiel de direction présentant une structure peu encombrante et très économique. Le dispositif est pourvu d'un premier organe d'entrée (51) mis en rotation par une unité d'entraînement (2), d'un deuxième organe d'entrée (54) mis en rotation par une unité de moteur de direction (3), et d'organes de sortie (43, 44) transmettant vers l'extérieur la puissance motrice appliquée aux organes d'entrée. Deux ensembles d'unités d'engrenages planétaires entraînent les premier et deuxième organes de sortie à la même vitesse dans la même direction en ne faisant tourner que le premier organe d'entrée (51) et en maintenant le deuxième organe d'entrée (54) à l'arrêt et, d'autre part, en ne faisant tourner que le deuxième organe d'entrée (54) et en maintenant le premier organe d'entrée à l'arrêt de manière à faire tourner les premier et deuxième organes de sortie à la même vitesse dans deux directions opposées, la première unité à engrenage planétaire (10) et la deuxième (30) étant disposées de manière à être coaxiales l'une par rapport à l'autre. La première unité à engrenage planétaire (10) est pourvue d'une paire d'engrenages planétaires comprenant deux engrenages (12, 13) en prise l'un avec l'autre.
