Abstract

UN AMORTIGUADOR ELASTOMERICO, TUBULAR (11) TIENE UN EJE CENTRAL (12) DISPUESTO DENTRO DE UN ALOJAMIENTO (13) Y RODEADO POR UN MIEMBRO ELASTOMERICO (14). SE SUMINISTRA UNA TENSION UNIFORME A TRAVES DEL ELASTOMERO DISPUESTO ENTRE EL EJE CENTRAL Y EL ALOJAMIENTO TANTO HACIENDO ADELGAZAR LA LONGITUD DEL ELASTOMERO DESDE LA SUPERFICIE INTERIOR DE UNION (15) HACIA UNA SUPERFICIE DE UNION EXTERIOR (16) DE MANERA QUE LA LONGITUD DEL RADIO EN CADA PUNTO A LO LARGO DEL ELASTOMERO SEA IGUAL, COMO SUMINISTRANDO UNA PRIMERA CAPA DE ELASTOMERO (28) DE FORMA ADYACENTE AL EJE (26) QUE TIENE UNA MAYOR RESISTENCIA A LA FATIGA/UNA MENOR CAPACIDAD DE AMORTIGUACION, UNA SEGUNDA CAPA DE ELASTOMERO (29) ADYACENTE AL ALOJAMIENTO (27) QUE TIENE UNA BAJA TENSION/UNA MAYOR CAPACIDAD DE AMORTIGUACION Y UNA CAPA DE ELASTOMERO INTERMEDIO (30) DE UNA TENSION Y AMORTIGUACION MODERADAS DE MANERA QUE DESDE EL RADIO INTERIOR HASTA EL RADIO EXTERIOR DEL MIEMBRO ELASTOMERICO, SE CONSIGA UNA TENSION UNIFORME. SUMINISTRANDO UNATENSION UNIFORME DESDE EL RADIO INTERIOR AL EXTERIOR DEL AMORTIGUADOR TUBULAR, ELASTOMERO, SE INCREMENTE LA TEMPERATURA DEBIDO A QUE SE EVITAN LAS ALTAS TENSIONES LOCALIZADAS QUE SON PERJUDICIALES PARA EL RENDIMIENTO DEL AMORTIGUADOR. OPCIONALMENTE, SE SUMINISTRAN CONDUCTOS AXIALES DE REFRIGERACION DENTRO DEL MIEMBRO ELASTOMERICO PARA ASEGURAR UN FUNCIONAMIENTO DENTRO LOS PARAMETROS DE DISEÑO, EXTENDIENDO DE ESTA FORMA LA VIDA DEL AMORTIGUADOR TUBULAR, ELASTOMERICO.
