ABSTRACT:
A steering column for a motor vehicle includes upper steering-column portion, a lower steering-column portion, and a damping body for coupling the upper and lower steering-column portions, with piezoelectric elements being integrated in the damping body. These piezoelectric elements are part of an active system for vibration damping and are provided for compensating vibrations in length direction of the steering column and torsional vibrations in rotational direction of the steering wheel. The active system further includes piezoelectric elements in an attachment zone between the A-pillars and the support beam for compensating vibrations in length direction of the support beam and perpendicular thereto. Thus, the active system for vibration damping thus provides a vibration control in all three directions in space as well as control of torsional vibration.
