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.
Claims11
A damper for dampening vibrations of a rotatable steering shaft of a motor vehicle, the damper comprising:
- a rotor;
- means for rotating the rotor at a rare proportional to and greater than rotation of the steering shaft the means for rotating including a drive member rotatable with the steering shaft and a driven member rotatable with the rotor;
- a gear loading bracket retaining the drive member with the drive member;
- and
- a magnetorheological fluid disposed at least partially around the rotor, the magnetorheological fluid having a viscosity variable to vary a load on the rotor.

A damper for dampening vibrations of a steering shaft of a motor vehicle, the damper comprising:
- a drive member rotatable with the steering shalt, the drive member having a first diameter;
- a rotor having a driven member engaged with the drive member, the driven member having a second diameter less than the first diameter;
- a gear loading bracket retaining the driven member with the drive member;
- and
- a magnetorheological fluid disposed around the rotor, the magnetorheological fluid having a viscosity variable to vary a load on the rotor.
