Abstract

A shaft arrangement is disclosed for transmitting torques acting around a rotational axis, with a variably adjustable torsional stiffness acting around the rotational axis and a method for varying the torsional stiffness of a shaft arrangement. The invention includes a first shaft section, having at least one torsion element secured thereto which is not damaged by torque and is axially fixed manner, which is mounted to be dimensionally stable transverse to the rotational axis, a second shaft section spaced axially apart from the first shaft section, to which the at least one torsion element is secured which is not rotatable but is axially movable and that a means for operatively interacts or can be made to operatively interact with the second shaft section for axially moving the second shaft section in relation to the first shaft section and in relation to the at least one torsion element.
