Abstract

L'INVENTION CONCERNE UN ELECTRO-AIMANT. SELON L'INVENTION, IL COMPREND UNE PLAQUE OBLONGUE 56 EN UN MATERIAU MAGNETIQUE DE FAIBLE RELUCTANCE, AVEC UN TROU 64, UN TETON 59 EN UN MATERIAU MAGNETIQUE DE FAIBLE RELUCTANCE PLACE DANS LE TROU ET PERPENDICULAIRE A LA PLAQUE, UNE BOBINE ANNULAIRE 65 PLACEE SUR LE TETON ET POUVANT ETRE CONNECTEE A UNE SOURCE DE TENSION, UN BLOC 71 D'UN MATERIAU DE FRICTION RECOUVRANT LA PLAQUE ET CORRESPONDANT A SA FORME, ET TRAVERSE D'UN TROU 75 RECEVANT LE TETON, AVEC UNE CAVITE 74, DANS LE BLOC, RECEVANT LA BOBINE, LE TETON DEFINISSANT UN POLE MAGNETIQUE D'UNE POLARITE; UN MOYEN 54 EN UN MATERIAU MAGNETIQUE DE FAIBLE RELUCTANCE S'ETENDANT DANS LA MEME DIRECTION QUE LE TETON DEFINIT UN POLE MAGNETIQUE D'UNE POLARITE OPPOSEE, CES POLES ETANT ESPACES L'UN DE L'AUTRE ET L'ESPACE ENTRE EUX ETANT OCCUPE PAR LE BLOC, CHAQUE POLE AYANT UNE FACE PARALLELE A LA PLAQUE ET PLACE SENSIBLEMENT DANS LE MEME PLAN QU'UNE FACE DU BLOC DE FRICTION. L'INVENTION S'APPLIQUE NOTAMMENT AUX FREINS POUR VEHICULES AUTOMOBILES.
