Abstract

UN DISPOSITIVO DE AMORTIGUACION DE VIBRACION (1) PARA MONTAR ENTRE DOS PARTES SEPARADAS DE UN VEHICULO PARA ABSORBER LAS FUERZAS DE LA VIA EJERCIDAS SOBRE EL VEHICULO. UN ALOJAMIENTO CILINDRICO DE METAL INTERIOR (2) FORMA UNA CAMARA DE PISTON INTERNA (38, 34) Y ESTA CONECTADA A UN EXTREMO EN UNA PARTE DEL VEHICULO, CON EL EXTREMO EXTERIOR DE LA VARILLA (12) DE UN PISTON (10) QUE ESTA MONTADO DESLIZABLEMENTE DENTRO DE LA CAMARA DE PISTON (38, 39), ESTANDO CONECTADO A LA OTRA PARTE DEL VEHICULO. UN ALOJAMIENTO EXTERIOR (25) RODEA UNA PARTE DEL ALOJAMIENTO INTERIOR (2) Y FORMA UN CONDUCTO DE TRANSFERENCIA DE FLUIDO (5) ENTRE CAMARAS DE FLUIDO (38, 39) FORMADAS EN LADOS OPUESTOS DEL PISTON (10) DENTRO DE LA CAMARA DEL PISTON (38, 39). UNA PLURALIDAD DE BANDAS DE ELECTRODO DE METAL SEPARADAS (52, 53, 54) ESTAN MONTADAS EN UNA SUPERFICIE INTERIOR (55) DEL ALOJAMIENTO EXTERIOR (25) Y ESTAN ELECTRICAMENTE AISLADAS DEL MISMO Y SE COMUNICAN CON EL CONDUCTO DE TRANSFERENCIA DE FLUIDO (5) PARA APLICARTENSIONES A TRAVES DEL CONDUCTO (5) PARA AFECTAR LA VISCOSIDAD DE UN FLUIDO ELECTRORREOLOGICO (ER) QUE FLUYE A TRAVES DEL MISMO PARA INCREMENTAR LA FUERZA DE AMORTIGUACION DEL DISPOSITIVO (1). CIERTAS BANDAS DE ELECTRODO (52, 53, 54) PUEDEN ESTAR FORMADAS CON UNA PLURALIDAD DE RANURAS SEPARADAS QUE SE EXTIENDEN LONGITUDINALMENTE SEPARADAS Y ACANALADURAS DE INTERVENCION, LAS CUALES SE ALINEAN CON LAS RANURAS Y LAS ACANALADURAS FORMADAS EN UN MANGUITO DE AISLAMIENTO DIELECTRICO MONTADO ADYACENTE AL CONDUCTO DE TRANSFERENCIA DE FLUIDO (5).
