Abstract

L'INVENTION CONCERNE UNE ROUE DE VEHICULE SUR RAILS. IL EST DECRIT UNE ROUE POURVUE D'UN BANDAGE OU JANTE DE ROULEMENT FABRIQUE A PARTIR D'UN ALLIAGE A MEMOIRE, CARACTERISEE EN CE QU'ELLE COMPORTE UN COMPOSANT ELASTIQUE POUR AMELIORER LA RESISTANCE DE LA ROUE AUX CHOCS MECANIQUES ET POUR REDUIRE LE BRUIT. LE BANDAGE OU JANTE DE ROULEMENT EST MIS EN PLACE EN LE DILATANT DIAMETRALEMENT ALORS QUE L'ALLIAGE EST A L'ETAT MARTENSITIQUE, EN LE PLACANT AUTOUR DE LA SURFACE DE PORTEE DU CORPS DE ROUE, ET EN AMENANT L'ALLIAGE A L'ETAT AUSTENITIQUE PAR CHAUFFAGE POUR QUE CE BANDAGE OU JANTE DE ROULEMENT SE CONTRACTE ET SE RESSERRE SUR LE CORPS DE ROUE AVEC UNE CERTAINE FORCE DE COMPRESSION. APPLICATION: ROUES DE WAGONS, LOCOMOTIVES.THE INVENTION RELATES TO A VEHICLE WHEEL ON RAILS. A WHEEL WITH A BANDAGE OR RIM MADE FROM A MEMORY ALLOY, CHARACTERIZED IN THAT IT INCLUDES AN ELASTIC COMPONENT TO IMPROVE THE WHEEL'S RESISTANCE TO MECHANICAL IMPACT AND TO REDUCE NOISE. THE BANDAGE OR RIM OF BEARING IS PLACED BY DIAMETRALLY EXPANDING IT WHILE THE ALLOY IS IN A MARTENSITIC STATE, BY PLACING IT AROUND THE WORKING SURFACE OF THE WHEEL BODY, AND BRINGING THE ALLOY TO THE STATE AUSTENITIQUE BY HEATING SO THAT THIS BANDAGE OR RIM OF BEARING CONTRACTS AND TIGHTENS ON THE WHEEL BODY WITH A CERTAIN COMPRESSION FORCE. APPLICATION: WAGON WHEELS, LOCOMOTIVES.
