Abstract

CE REGULATEUR COMPORTE UN BALANCIER 29 DONT LA POSITION DU POINT D'APPUI 28 DEPEND DE LA CHARGE APPLIQUEE A UN ESSIEU 15 DU VEHICULE ET QUI COMMANDE L'ENVOI DE LIQUIDE HYDRAULIQUE D'UN MAITRE-CYLINDRE 12 PAR L'INTERMEDIAIRE D'UNE SOUPAPE A BILLE 43, 44 AUX FREINS DE L'ESSIEU. LA PRESSION DE FREINAGE AGIT SUR LE BALANCIER 29 PAR L'INTERMEDIAIRE D'UN PISTON 46 A L'ENCONTRE DE LA PRESSION DU MAITRE-CYLINDRE, QUI AGIT PAR L'INTERMEDIAIRE D'UN PISTON 35, ET DE LA FORCE D'UN RESSORT PRECHARGE 51. LE TAUX D'ACCROISSEMENT DE LA PRESSION DE FREINAGE AU-DESSUS D'UNE VALEUR DONNEE DEPEND DE LA POSITION DU POINT D'APPUI DU BALANCIER. APPLICATION AUX CIRCUITS DE FREINAGE DES VEHICULES UTILITAIRES.
