Abstract

SUR CHAQUE COTE D'UN VEHICULE, LES ROUES OU CHENILLES SONT MUES PAR UN MOTEUR HYDRAULIQUE 14, 16 QUI EST MONTE EN UN CIRCUIT FERME 10, 12 AVEC UNE POMPE 2, 4 ENTRAINEE PAR UN MOTEUR THERMIQUE 6. L'INSTALLATION COMPREND TROIS DISTRIBUTEURS A COMMANDE MANUELLE, UN PREMIER 52 ALIMENTE PAR UNE POMPE 54 POUR REGLER LA VITESSE DU VEHICULE ET LE FAIRE PASSER DE LA MARCHE AVANT A LA MARCHE ARRIERE ET VICE VERSA ET DEUX AUTRES 64, 66 ALIMENTES PAR UNE POMPE 26 POUR DIRIGER LE VEHICULE. UN DISTRIBUTEUR SUPPLEMENTAIRE 76 EST ASSERVI AUX DISTRIBUTEURS DE DIRECTION 64, 66 DE FACON A PASSER D'UNE POSITION D'ETRANGLEMENT 76A A UNE POSITION DE LIBRE PASSAGE 76A LORS DES MANOEUVRES DE DIRECTION.
