Abstract

UN CONTROL DE SUSPENSION PARA UN VEHICULO DE RUEDAS INCLUYE UN AMORTIGUADOR 20 ENTRE EL CHASIS DEL VEHICULO 10 Y LA RUEDA 11, EL AMORTIGUADOR 20 PUEDE SER PUESTO EN FUNCIONAMIENTO A UNA FRECUENCIA DE AL MENOS DEL DOBLE DE LA FRECUENCIA DE VIUTACION RESONANTE DE LA RUEDA, ENTRE UNA PRIMERA MANERA DE OPERACION QUE PRODUCE UNA FUERZA ALTA DE AMORTIGUACION Y UNA SEGUNDA QUE PRODUCE UNA FUERZA DE AMORTIGUACION BAJA. UN CONTROLADOR 15 DERIVA REPETIDAMENTE DESDE LAS VARIABLES DE OPERACION DEL VEHICULO, UNA FUERZA ACTUADORA, PARA SER APLICADA ENTRE EL CHASIS 10 Y LA RUEDA 11 PARA PRODUCIR UN COMPORTAMIENTO DE SUSPENSION DESEADO, Y DETERMINA SI ESA FUERZA RESULTARA UN PODER ACTIVO O DISIPATIVO DE SUSPENSION. MAS ADELANTE, EL CONTROLADOR 15 ALMACENA UN LIMITADOR DE VALVULA DE CONTROL Y CONTROLA EL AMORTIGUADOR 20 PARA CADA DERIVACION DE TAL MANERA QUE (1) EL AMORTIGUADOR 20 FUNCIONA DE SU SEGUNDA MANERA, CUANDO LA FUERZA DEL ACTUADOR PRODUZCA MENOR ACCION (2), EL AMORTIGUADOR 20 FUNCIONA DE SU PRIMERMODO CUANDO LA FUERZA DEL ACTUADOR EXCEDE UNA LIMITACION Y PRODUZCA UNA FUERZA DESIPATIVA, Y (3) EL AMORTIGUADOR 20 FUNCIONA DE SU SEGUNDA MANERA CUANDO LA FUERZA DEL ACTUADOR ES MENOR QUE LA LIMITADA Y PRODUZCA FUERZA DESIPADORA. EL CONTROLADOR PUEDE SER UTILIZADO TAMBIEN CON SUSPENSIONES ACTIVAS.
