Abstract
A steering column of a commercial vehicle having a natural frequency of vibration is provided. The steering column includes an input shaft disposed within the steering column. The input shaft is coupled to a steering wheel at a first end. An output shaft is disposed within the steering column. A second end of the output shaft is coupled to a steering gear and a first end of the output shaft is connected to a second end of the input shaft. A torsion bar is disposed within the steering column. A first end of the torsion bar is connected to the second end of the input shaft and a second end of the torsion bar is connected to the first end of the output shaft. The torsion bar is designed to have a stiffness selected to dampen an amplitude of vibration of the steering column at the natural frequency.
