Abstract (en)
[origin: WO2014194989A1] The present invention discloses a drive shaft (1) which has at least one outer shaft section (11) with a hollow end section of cylindrical internal cross section and at least one inner shaft section (12) which penetrates at least along a first penetrating depth (L1) into the hollow end section of the outer shaft section (11). The shaft sections (11, 12) are connected in an integrally joined manner on a contact surface between an outer wall of the inner shaft section (12) and an inner wall of the outer shaft section (11) along the first penetrating depth (L1). The integrally joined connection (12') has a longitudinally axial load-bearing capability, which is lower than a predefined buckling force, for buckling the shaft sections (11, 12) when the drive shaft (1) is loaded in a longitudinally axial manner. The inner shaft section (12) can penetrate more deeply than the first penetrating depth (L1) into the hollow end of the outer shaft section (11) when an axial force is applied which is greater than the buckling force.
