Abstract

A damper for dampening vibrations of a rotatable steering shaft of a motor vehicle comprises a rotor and means for rotating the rotor at a rate proportional to and greater than rotation of the steering shaft. Magnetorheological fluid is disposed at least partially around the rotor, and has a viscosity variable to vary a load on the rotor.
