A bellows accumulator for a vehicle suspension system and an associated method of operating the accumulator include inserting a bellows assembly within a housing. The bellows assembly includes an annular bellows wall defining a variable volume plenum. An energy storage chamber is arranged between the shell and the corrugated pipe assembly. The method includes operating a valve in fluid communication with the energy storage chamber in an open state and a closed state, charging fluid into the energy storage chamber prior to charging the gas chamber with pressurized gas, providing a pressure difference between the pressurized gas chamber and the energy storage chamber to extend the annular bellows wall to operate the valve in the closed state. The method includes protecting the bellows wall during pre-inflation of the pressurized plenum and during operation of the vehicle suspension by retaining fluid between the housing and the annular bellows wall.
用于车辆悬架系统的波纹管蓄能器和操作蓄能器的相关方法,包括在外壳内插入波纹管组件。波纹管组件包括限定容积可变的气室的环形波纹管壁。在外壳和波纹管组件之间设置有蓄能室。该方法包括在打开状态和关闭状态下操作与蓄能室流体连通的阀门,在向气室充入加压气体之前向蓄能室充入流体,在加压气室和蓄能室之间提供压力差,以伸展环形波纹管壁使阀门在关闭状态下工作。该方法包括通过保持外壳和环形波纹管壁之间的流体,在加压气室预充气期间以及车辆悬架运行期间保护波纹管壁。
