Abstract

LA PRESENTE INVENCION SE REFIERE A UN ACCIONAMIENTO DE CUBO DE RUEDA PARA UN VEHICULO (1, 4), EN PARTICULAR PARA UNA RUEDA (1) DE UN VEHICULO DE CARRIL, QUE INCLUYE UN MOTOR DE ROTOR EN DONDE LA CARCASA DEL ROTOR (8) ESTA UNIDA A LA RUEDA DEL VEHICULO (1) Y EL ESTATOR (S) SE ASIENTA SOBRE UN EJE EN REPOSO (14), ESTANDO EL EJE (14) COLGADO POR UN LADO EN EL BASTIDOR DEL VEHICULO (19) O EN UN ELEMENTO SIMILAR. PARA PODER SUSTITUIR DE FORMA MAS SENCILLA Y RAPIDA LAS PIEZAS DE DESGASTE COMO, POR EJEMPLO, EL NEUMATICO RADIAL (1), EL DISCO DE FRENO (22) O LA TOMA A TIERRA (27), Y PARA PODER SUSTITUIR ASIMISMO DE FORMA SENCILLA EL ACCIONAMIENTO DE CUBO DE RUEDA COMPLETO, LA INVENCION PREVE QUE PARA COLGAR EL EJE POR UN LADO LA OPERACION SE REALICE A TRAVES DE UNA PLACA DE SOPORTE (6) UNIDA AL EJE (14), PRESENTANDO LA PLACA (6) UN PIVOTE (7) QUE SE INTRODUCE A TRAVES DE UN ORIFICIO (15) EN EL EJE (14) HASTA EL INTERIOR DEL ACCIONAMIENTO DE CUBO DE RUEDA. LA PLACA DE SOPORTE (6) FORMA PARTE INTEGRANTE DEL CONJUNTO COLGANTE Y AL MISMO TIEMPO ACTUA COMO PLACA DE COJINETE, OBTENIENDOSE ASI UNA LONGITUD MENOR Y RESULTANDO MAS SENCILLO EL MANEJO Y EL MANTENIMIENTO DEL ACCIONAMIENTO.
