Abstract
A steering column for a motor vehicle having a steering shaft mounted in a steering column tube so as to be rotatable about a longitudinal axis and a damping device. The damping device has an element which is stationary in relation to the steering column tube and a rotatable element which is coupled in terms of rotation to the steering shaft. The rotatable element is rotatable relative to the stationary element about an axis of rotation. A damping fluid is arranged between the rotatable and the stationary element. The steering column thus permits operationally reliable damping of the steering shaft in a steering system. At least two surfaces of the rotatable element are provided, which are parallel to the axis of rotation, are in contact with the damping fluid, and are arranged so as to be spaced apart coaxially from one another.
