Abstract
UN DISPOSITIVO DE AMORTIGUACION DE VIBRACION PARA MONTAR ENTRE DOS PARTES SEPARADAS DE UN VEHICULO PARA ABSORBER LAS FUERZAS DE LA CARRETERA EJERCIDAS EN EL VEHICULO. UN ALOJAMIENTO CILINDRICO DE METAL INTERIOR (2) FORMA UNA CAMARA DE PISTON INTERNA Y ESTA CONECTADO A UN EXTREMO DE UNA PARTE DEL VEHICULO, CON EL EXTREMO EXTERIOR DE LA VARILLA DE UN PISTON QUE ESTA MONTADO DE FORMA DESLIZABLE EN LA CAMARA DE PISTON, ESTANDO CONECTADO A LA OTRA PARTE DEL VEHICULO. UN ALOJAMIENTO EXTERIOR (25) RODEA UNA PARTE DEL ALOJAMIENTO INTERIOR Y FORMA UN CONDUCTO DE TRASPASO DE FLUIDO ENTRE LAS CAMARAS DE FLUIDO FORMADAS EN LOS LADOS OPUESTOS DEL PISTON EN LA CAMARA DE PISTON. UN ELECTRODO (52) ESTA MONTADO EN UNA SUPERFICIE INTERIOR DEL ALOJAMIENTO EXTERIOR Y ESTA ELECTRICAMENTE AISLADO DEL MISMO Y SE COMUNICA CON EL CONDUCTO DE TRASPASO DE FLUIDO PARA APLICAR UNA TENSION EN EL CONDUCTO QUE AFECTE A LA VISCOSIDAD DE UN FLUIDO ELECTROREOLOGICO (ER) QUE FLUYE A TRAVES DEL MISMO PARA AUMENTAR LA FUERZA DEAMORTIGUACION DEL DISPOSITIVO.
