Abstract

DISPOSITIF DE COMMANDE DE CHANGEMENT DE VITESSE DANS UNE TRANSMISSION A PLUSIEURS RAPPORTS DE VITESSES. IL COMPREND UN ELEMENT ELECTRONIQUE DE DETECTION DE VITESSE ET DES SOUPAPES DE COMMANDE DE RETROGRADATION QUI FONT PASSER AUTOMATIQUEMENT LA TRANSMISSION D'UN RAPPORT DE VITESSES ELEVE A UN RAPPORT INFERIEUR LORSQUE LA VITESSE DU VEHICULE PAR RAPPORT AU SOL ATTEINT UNE PREMIERE VALEUR PREDETERMINEE. UN CIRCUIT DE TEMPORISATION OU D'INHIBITION EMPECHE TOUTE RETROGRADATION DU RAPPORT ELEVE AU RAPPORT INFERIEUR LORS D'UNE MANOEUVRE D'INVERSION DU SENS DE MARCHE DE VEHICULE A PLEINS GAZ. DOMAINE D'APPLICATION: CHARGEURS A BENNE FRONTALE, ENGINS DE TRAVAUX PUBLICS, ETC.
