Abstract

PATIN ELECTROMAGNETIQUE EN PARTICULIER POUR LE FREINAGE D'UN VEHICULE FERROVIAIRE PAR APPLICATION SUR LE RAIL DE ROULEMENT DE CE VEHICULE ET DU TYPE COMPORTANT UNE SERIE DE PATINS FROTTEURS ELEMENTAIRES. IL COMPORTE DES BOBINES ANNULAIRES D'EXCITATION 6 DONT LE PLAN VERTICAL MEDIAN DE SYMETRIE EST ORIENTE DANS LE SENS DU RAIL 3 ET DES NOYAUX FERROMAGNETIQUES AMOVIBLES 8 EN U RENVERSE ET PERPENDICULAIRES AU RAIL 3. APPLICATION AU FREINAGE FERROVIAIRE A L'AIDE DE PATINS MAGNETISES SOLIDAIRES DU BOGIE POUR OBTENIR UNE FRICTION SUR LE RAIL DE ROULEMENT NE FAISANT PAS APPEL A L'ADHERENCE.ELECTROMAGNETIC SKATE IN PARTICULAR FOR THE BRAKING OF A RAILWAY VEHICLE BY APPLICATION ON THE TRACK OF THIS VEHICLE AND OF THE TYPE INCLUDING A SERIES OF ELEMENTARY SKATES. IT INCLUDES 6 ANNULAR EXCITATION COILS WHOSE VERTICAL MEDIAN PLANE OF SYMMETRY IS ORIENTED IN THE DIRECTION OF RAIL 3 AND REMOVABLE U-SHAPED FERROMAGNETIC CORES 8 INVERTED AND PERPENDICULAR TO RAIL 3. APPLICATION TO RAIL BRAKING USING MAGNETIC SHOES SOLIDARITY WITH THE BOGIE TO OBTAIN FRICTION ON THE TRACKING RAIL THAT DOES NOT REQUIRE GRIP.
