  • HYDRAULIC DAMPER
    Publication number: 20090127019
    Abstract: The present invention provides a damping system for use with a mechanism such as a steering system wherein one element moves relative to another element. The system includes a variable volume chamber, a collection chamber, and an inertia track providing fluid communication between the two chambers. A fluid is disposed in the chambers and the inertia track. A compliant tuning member is in fluid communication with the variable volume chamber. The damping system is capable of attenuating vibration at chosen frequencies without adding undesired damping at other frequencies. In the preferred embodiment, the damping system is used to attenuate steering wheel torsional vibration without increasing low frequency damping that would deteriorate steering feel.
