Abstract

EMBRAYAGE A COLLIER A COMMANDE ELECTROMECANIQUE. L'EMBRAYAGE COMPORTE UN ORGANE MENANT12 PORTANT UNE BOBINE ELECTROMAGNETIQUE ET UN ORGANE MENE 36 MONTE A ROTATION SUR L'ORGANE MENANT ET ENTOURANT LA BOBINE DE FACON A FORMER AVEC LES PIECES POLAIRES DE CETTE DERNIERE UN ENTREFER50. UN COLLIER D'ACCOUPLEMENT EST DISPOSE DANS L'ENTREFER ET COMPORTE UNE BANDE INTERIEURE 54 CONSTITUEE PAR DES SEGMENTS ARQUES 58, 60, 62 DE MATIERE MAGNETIQUE RACCORDES ENTRE EUX PAR DES SEGMENTS FLEXIBLES 64, 66 ET UNE BANDE EXTERIEURE ELASTIQUE56 QUI PORTE UN REVETEMENT DE FRICTION 70 EN APPUI DE FRICTION CONTRE L'ORGANE MENE DE SORTE QUE, LORSQUE LA BOBINE EST EXCITEE, LA BANDE INTERIEURE S'APPLIQUE CONTRE L'ORGANE MENANT, ENTRAINANT L'ORGANE MENE PAR L'INTERMEDIAIRE DU REVETEMENT DE FRICTION. CET AGENCEMENT PERMET UN MEILLEUR SERRAGE DU COLLIER ET AMELIORE LA CAPACITE DE TRANSMISSION DE COUPLE DE L'EMBRAYAGE. APPLICATION A UN EMBRAYAGE DE VENTILATEUR DE MOTEUR A COMBUSTION INTERNE.
