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).
Claims21
A spring device (100), the spring device (100) comprising an elongated elastic torsion device (102) configured to rotate about a central longitudinal axis (R) at a load (L), the torsion device (102) comprising:
- an elongated internal profile (110) having a longitudinal axis along the central longitudinal axis (R);
- an elongated external profile (120) comprising an elongated cavity (122) having a longitudinal axis along the central longitudinal axis (R),
- at least three elongated elastic elements (130) having a longitudinal axis parallel to the central longitudinal axis (R);
- wherein the internal profile (110) and the elongated elastic elements (130) are at least partially located in the cavity (122) of the external profile (120), and
- wherein the elongated elastic elements (130), respectively, are arranged at different angular positions about the central longitudinal axis (R) between the internal profile (110) and the external profile (120) so that a rotation about the central longitudinal axis (R) is realized under load by an elastic deformation of the elongated elastic elements,
- CHARACTERIZED BY
- the elongated elastic elements (130) comprising an internal cavity (132) configured to comprise a pressurized gas.
