Abstract (en)

[origin: WO2008133720A1] A controllable suspension system for controlling the relative motion between a first body (22) and a second body (24) includes at least one strut (30) including a magneto-rheological fluid damper (32,200). The fluid damper (32,200) includes a piston rod guide (206) disposed within a damper body (202). The piston rod guide (206) has a passage (212) therein for receiving a piston rod (52,214). A piston rod bearing assembly (54,232) is disposed in the piston rod guide (206) to engage with and support reciprocal motion of the piston rod (52,214). At least a first piston rod seal (224) and at least a second piston rod seal (228) are arranged to seal between the piston rod guide (206) and the piston rod (52,214). A fluid chamber (234) is defined between the piston rod guide (206) and the piston rod (52,214). A piston rod guide (206) gas charged accumulator (244,272) is arranged between the piston rod (52,214) and the damper body (202).
