An X-shaped spring device for a transportation vehicle wheel suspension, the transportation vehicle including a first wheel side and a second wheel side, the X-shaped spring device comprising:
- a first leaf spring and a second leaf spring arranged on each of the first wheel side and the second wheel side, each of the first and second leaf springs being formed of fiber-reinforced plastics material, each of the first and second leaf springs being arranged one above the other and joined at first ends on a first securing device for support at a transportation vehicle structure side,
- wherein the first leaf spring has, at a second end, a second securing device for wheel-side support,
- wherein the second leaf spring is supported at a second end at the transportation vehicle structure side,
- wherein the second leaf spring forms a curved portion curved away from the first leaf spring toward the second end of the second leaf spring,
- wherein a first surface of the second leaf spring which initially faces the first leaf spring subsequently faces toward the second end of the second leaf spring away from the first leaf spring, and
- wherein the second end of the second leaf spring is attached to an underside of a longitudinal carrier of the transportation vehicle located adjacent the transportation vehicle structure side.
