Abstract

L'INVENTION A TRAIT A UN CONVERTISSEUR HYDROSTATIQUE DE REGLAGE MUNI D'UN MOTEUR HYDROSTATIQUE, D'UNE POMPE HYDROSTATIQUE ET D'UN MECANISME DE CHANGEMENT DE VITESSE EN FONCTION DE LA CHARGE DISPOSE EN AVAL. LA PRESSION DE REMPLISSAGE ET DE VIDANGE DES ACCOUPLEMENTS EST DELIVREE A UN DISTRIBUTEUR COMME PRESSION D'EMBRAYAGE, ET DES REGULATEURS DE PRESSION DETERMINENT L'ALLURE DE LA PRESSION, LORS DU REMPLISSAGE ET DE LA VIDANGE DE L'ACCOUPLEMENT, DE SORTE QUE L'ASSERVISSEMENT DU MECANISME HYDROSTATIQUE, LORS DU CHANGEMENT DE RAPPORT, S'EFFECTUE EN DEHORS DU MOUVEMENT FORCE DU MECANISME EN FONCTION DE L'ALLURE DU TRANSFERT DE CHARGE A L'ACCOUPLEMENT DEBRAYE ET A L'ACCOUPLEMENT EMBRAYE. APPLICATION NOTAMMENT AUX TRANSMISSIONS HYDROSTATIQUES.
