CONTROLLABLE VEHICLE SUSPENSION SYSTEM WITH MAGNETO-RHEOLOGICAL FLUID DEVICE

摘要

A controllable suspension system for controlling the relative motion between a first body and a second body includes at least one strut including a magneto-rheological fluid damper. The fluid damper includes a piston rod guide disposed within a damper body. The piston rod guide has a passage therein for receiving a piston rod. A piston rod bearing assembly is disposed in the piston rod guide to engage with and support reciprocal motion of the piston rod. At least a first piston rod seal and at least a second piston rod seal are arranged to seal between the piston rod guide and the piston rod. A fluid chamber is defined between the piston rod guide and the piston rod. A piston rod guide gas charged accumulator is arranged between the piston rod and the damper body.
