Abstract: An active suspension system is configured in a strut arrangement. The active suspension system comprises a hydraulic actuator and a hydraulic pump/electric motor assembly, wherein the actuator movement is preferably in lockstep with the hydraulic motor-pump and electric motor-generator combination. Torque in the electric motor is instantaneously controlled by a controller to create an immediate force change on the hydraulic actuator. The hydraulic actuator is configured so that it can be used as a strut whereby the actuator has sufficient structural rigidity to carry the applied suspension loads while capable of supplying damper forces in at least three quadrants of the force velocity graph of the suspension actuator operation. Embodiments disclosed include low cost active suspension systems for a MacPherson strut application.

Abstract translation: 主动悬挂系统配置为支柱装置。 主动悬挂系统包括液压致动器和液压泵/电动机组件，其中致动器运动优选地与液压马达泵和电动发电机组合在一起。 电动机中的扭矩由控制器瞬时控制，以在液压致动器上产生立即的力变化。 液压致动器被构造成使得其可以用作支柱，由此致动器具有足够的结构刚度来承载所施加的悬架载荷，同时能够在悬架致动器操作的力速度图的至少三个象限中提供阻尼力。 公开的实施例包括用于MacPherson支柱应用的低成本主动悬挂系统。
