Abstract

TRANSMISSION HYDROSTATIQUE POUR VEHICULE AUTOMOBILE, COMPRENANT UNE POMPE HYDRAULIQUE A CYLINDREE REGLABLE, ENTRAINEE PAR UN MOTEUR, NOTAMMENT THERMIQUE, ET DEBITANT DU LIQUIDE VERS AU MOINS UN MOTEUR HYDRAULIQUE PROPRE A ENTRAINER UN OU DES ORGANES DE LIAISON DU VEHICULE AVEC LE SOL, ORGANES DE LIAISON NOTAMMENT CONSTITUES PAR DES ROUES. LA TRANSMISSION COMPORTE UN ACCUMULATEUR 7 BRANCHE SUR LE CIRCUIT HAUTE PRESSION HP; LE MOTEUR HYDRAULIQUE 4 EST DU TYPE A CYLINDREE REGLABLE ET A INVERSION DE CYLINDREE; DES MOYENS D'AFFICHAGE 13 D'UNE VITESSE SOUHAITEE PAR LE CONDUCTEUR, ET DES MOYENS DE COMMANDE S DE LA CYLINDREE DU MOTEUR SONT PREVUS POUR COMMANDER UNE CYLINDREE POSITIVE LORSQUE LA VITESSE EFFECTIVE DU VEHICULE EST INFERIEURE A LA VALEUR AFFICHEE, ET UNE CYLINDREE NEGATIVE LORSQUE LA VITESSE EFFECTIVE EST SUPERIEURE A LA VALEUR AFFICHEE, L'INVERSE ETANT REALISE LORSQUE LE VEHICULE CIRCULE EN MARCHE ARRIERE. APPLICATION AUX VEHICULES URBAINS, NOTAMMENT AUX AUTOBUS URBAINS.
