Abstract

L'invention a trait au domaine des commandes de freinage et de braquage de véhicules à chenilles. Le mécanisme de commande hydraulique selon l'invention est essentiellement caractérisé par le fait qu'il comprend une valve combinée de freinage et de braquage munie de deux tiroirs actionnés par des leviers, associée à un distributeur de fluide et à une valve supplémentaire de freinage en liaison avec une pédale unique, ladite valve combinée agissant sur des embrayages et sur des freins des chenilles. Application aux véhicules à chenilles.
