Abstract
LA INVECION SE REFIERE A UN PROCESO PARA LA REGULACION DE LA DISTANCIA ENTRE UN BASTIDOR (35) Y UNA UNIDAD DE RUEDA O EJE (36) EN UN VEHICULO A MOTOR, MEDIANTE UN ELEMENTO AMORTIGUADOR HIDRONEUMATICO (18A) GRACIAS A LA MODIFICACION DEL VOLUMEN DE UN LIQUIDO AMORTIGUADOR (22) Y UNA AMORTIGUACION HIDRONEUMATICA PARA VEHICULOS. EL BASTIDOR ESTA AMORTIGUADO MEDIANTE MUELLES HIDRONEUMATICOS (18) EN AMBOS LADOS DEL VEHICULO Y SOBRE UNO O MAS EJES DE RUEDAS, SIENDO EL VOLUMEN DE UNO DE LOS MUELLES HIDRONEUMATICOS VARIABLE. PARA AUMENTAR LA DISTANCIA SE AUMENTA EL VOLUMEN ESTATICO EN UN VOLUMEN ADICIONAL (3) O PARA REDUCIR LA DISTANCIA SE REDUCE EL VOLUMEN ESTATICO EN UN VOLUMEN DE REDUCCION (4). A CADA MUELLE HIDRONEUMATICO, O A UN GRUPO DE VARIOS EN PARALELO, SE LE ASOCIA UNA UNIDAD DE DOSIFICACION (21), QUE PUEDE AÑADIR O DISMINUIR EL VOLUMEN TOTAL DE AMORTIGUACION DE LOS MUELLES HIDRODINAMICOS ASOCIADOS EN, AL MENOS, UN VOLUMEN ADICIONAL O DE REDUCCION DEFINIDO, Y HACE POSIBLE LA REGULACION, ENLA ZONA DE LOS MUELLES HIDRONEUMATICOS ASOCIADOS A LA UNIDAD DE DOSIFICACION, DE LA DISTANCIA BASTIDOR DEL VEHICULO/EJE DE LAS RUEDAS, A TRAVES DE LA DETERMINACION DEL VALOR ACTUAL DE OPERACION DE LA UNIDAD DE DOSIFICACION MEDIANTE UN SENSOR SITUADO SOBRE ELLA, Y, EN SU CASO, PERMITE UNA REGULACION POSTERIOR AJUSTANDO EL VALOR ACTUAL A UN VALOR DE CONSIGNA DE OPERACION.
