Abstract

INVENTION CONCERNANT LE FREINAGE DES VEHICULES. UN ACTUATEUR DE FREIN 1 COMPREND UN BOITIER 2 FERME PAR UNE PAROI D'EXTREMITE AMOVIBLE 5. UNE TIGE DE SORTIE 3 EST MONTEE AVEC COULISSEMENT DANS LE BOITIER ET SOLLICITEE POUR L'APPLICATION DU FREIN PAR UN RESSORT 10. EN FONCTIONNEMENT NORMAL LE FREIN EST MAINTENU ECARTE PAR LA PRESSION HYDRAULIQUE DANS UN CYLINDRE 13 FORME PAR UN PERCAGE DANS LA TIGE 3. UN PISTON 14 EST SUPPORTE RIGIDEMENT PAR LA PAROI D'EXTREMITE 5 ET SERT DE GUIDE POUR LA TIGE DE SORTIE. DU FLUIDE HYDRAULIQUE ALIMENTE LE CYLINDRE 13 PAR UN PERCAGE 18 DANS LE PISTON. LE RELACHEMENT DU FREIN EN CAS DE BESOIN EST PROCURE PAR UN MANCHON 24 COMPORTANT DES FILETAGES INTERNE ET EXTERNE EN SENS OPPOSES. APPLICATION A LA REALISATION DE FREINS POUR VEHICULES, AVEC ACTUATEURS COMPACTS.
