Abstract

a. Système d'entraînement à transmissions hydrostatiques comprenant un moteur commun d'entraînement, deux transmissions hydrostatiques incluant chacune un groupe de pompage et un groupe moteur à débit variable relié au précedent par une boucle hydrostatique, une soupape commune de commande de vitesse et deux soupapes de commande de direction agissant sélectivement. sur l'une ou sur l'autre des deux transmissions. b. Le système d'entraînement selon l'invention inclut deux pompes de charge 60, 62 alimentant chacune l'une des transmissions hydrostatiques 14, 16, ainsi que des moyens provoquant en cas d'abaissement anormal de la pression de charge le retour à l'état inopérant des deux transmissions et la mise en court-circuit de leurs boucles hydrostatiques respectives. c. Application notamment à l'entraînement des véhicules à chenilles.
