Abstract

Una configuración de muelle comprende un amortiguador cilíndrico, un muelle de bobina primario con una primera tasa de muelle predeterminada K1, y un muelle de bobina secundario con una segunda tasa de muelle predeterminada K2, los muelles de bobina acomodados alrededor del amortiguador cilíndrico en serie para proporcionar una tasa de muelle combinada total KT, un actuador configurado para comprimir y descomprimir los muelles de bobina, un tope configurado para desactivar el muelle de bobina secundario en una posición de parada, de manera que, cuando el sistema está en un primer modo de comodidad, la tasa de muelle de suspensión general es definida por la ecuación en serie 1/KT = 1/K1 + 1/K2, y cuando el sistema está en un segundo modo de manipulación la tasa de muelle de suspensión de vehículo general es definida por la ecuación en serie KT = K1, proporcionando así de manera selectiva y conmutable tanto una tasa baja, la configuración de comodidad de recorrido óptima como una tasa alta, la configuración de altura de recorrido inferior de manipulación óptima.
