Abstract

The invention relates to shaft (1) with adjustable stiffness, wherein at least one torsion bar (2), which is surrounded by a tubular sleeve (3), is arranged between a first shaft attachment (8) and a second shaft attachment (15), wherein at least one shaft attachment (8) is arranged at a first end (2a) of the torsion bar (2), and wherein preferably at least one first damping element (4a, 4b, 4c) is arranged between the tubular sleeve (3) and the torsion bar (2), wherein the tubular sleeve (3) can be connected in a rotationally fixed and releasable manner at at least one end (11, 16) to the torsion (2) bar by means of at least one connection element (10, 20, 30). In order to permit, in the simplest possible manner, a durable but when necessary variable adjustability of the torsional stiffness in order to match the rotational oscillation behaviour, it is provided that the first shaft attachment (8) is formed by a first connection flange (7) which can be connected in a rotationally fixed and releasable manner to a corresponding first counter-flange (9) in the region of the first end (11) of the tubular sleeve (3) by means of at least one first connection element (10) preferably formed by at least one screw connection.
