Abstract: A spring device (100) for a wheel suspension (200) for a vehicle (300) is described. The spring device (100) comprises an elongated elastic torsion device (102) configured to rotate about a central longitudinal axis (R) at a load (L). The torsion device (102) comprises elongated elastic elements (130) that comprise an internal cavity (132).
