Abstract
A vibration damper assembly to dampen the vibration generated in a motor vehicle and transmitted through, for example, a steering assembly. The vibration damper assembly includes a rotor disposed within a housing. The rotor is operatively connected to a velocity generating member such as a pinion that is integrated with the steering assembly. A conductive sleeve is disposed between the housing and the rotor. A coil engages the sleeve and is capable of generating a magnetic field that is transmitted through the sleeve. A plate separates the rotor from the sleeve thereby defining a viscous fluid chamber and a Magneto-Rheological (MR) fluid chamber between the rotor and the sleeve. The viscous fluid chamber includes a Newtonian fluid and the MR fluid chamber includes a MR fluid having sheer properties reactive to the magnetic field.
