A suspension system (201) for a motor vehicle includes a hydraulic actuator (205) for mounting between a wheel assembly (209) and a body (207) of the motor vehicle. The system also includes a hydraulic system (210) configured to provide a fluid supply to the hydraulic actuator. The hydraulic system is configured to provide a fluid having a static pressure greater than 7 MPa (70 Bar) to the hydraulic actuator during normal operation. In embodiments of the present application, a hydraulic system includes a plurality of gas accumulators (222, 232, 242) wherein the system is configured to communicate a change in fluid pressure between a hydraulic actuator, a common flow path, and the gas accumulators such that the hydraulic actuator has a first stiffness when the hydraulic system is in a first configuration and a second stiffness when the hydraulic system is in a second configuration. And has a different second stiffness when the hydraulic system is in the second configuration.

    一种用于机动车辆的悬架系统(201),其包括用于安装在机动车辆的车轮组件(209)和车身(207)之间的液压执行器(205)。所述系统还包括配置成向液压执行器提供流体供应的液压系统(210)。液压系统配置为在正常操作期间向液压执行器提供静压大于7MPa(70Bar)的流体。在本申请的实施方案中,液压系统包括多个气体蓄能器(222,232,242),其中所述系统被配置为在液压执行器、公共流动路径和气体蓄能器之间传送流体压力的变化,使得液压执行器当液压系统处于第一构型时具有第一刚度,并且当液压系统处于第二构型时具有不同的第二刚度。
