Abstract

DISPOSITIF DE REGULATION AUTOMATIQUE DE LA FORCE DE FREINAGE DE VEHICULES OU REMORQUES EN FONCTION DE LA CHARGE. UN PISTON DE REGLAGE 3, 4, CONSTITUE PAR UN PISTON DE COMMANDE 3 ET UNE MEMBRANE 4, ACTIONNE UNE SOUPAPE DOUBLE DE REGLAGE DE LA PRESSION DE FREINAGE 6, 7 ET DE SORTIE 6, 8. LA SURFACE SUPERIEURE 12 DU PISTON DE COMMANDE EST CHARGEE PAR LA PRESSION DE COMMANDE D'UN TRANSMETTEUR DE PRESSION DE FREINAGE. AU-DESSOUS DE LA MEMBRANE 4 SE TROUVE UNE CHAMBRE 16 RELIEE PAR UN RACCORD 17 AUX CYLINDRES DE ROUE. LA GRANDEUR REGLEE EST AJUSTABLE EN FONCTION DU POIDS DU VEHICULE. UN LIMITEUR DE PRESSION 23 RELIE LES CHAMBRES 16 ET 18 SITUEES DE PART ET D'AUTRE DE LA MEMBRANE 4.
