Leaf spring arrangement in the chassis of a vehicle

The invention relates to an arrangement of a leaf spring (5) in the chassis of a vehicle, whose spring force characteristic acting between the vehicle body (3) and at least one wheel (1) of the vehicle can be modified, wherein the leaf spring (5) can be secured in the chassis with its ends such that it can be secured in at least two different rotational positions resulting from an at least minor rotation of the leaf spring (5) about an axis extending in the longitudinal direction thereof. On a two-track vehicle, the ends of the spring leaf (5) extending in the transverse direction of the vehicle and arranged centrally relative to the vehicle axle can each be connected via a coupling element (7) to an extension arm (6), on the other end of which a wheel (1) of the axle is supported, while the vehicle body (3) is supported on, or directly adjacent to, the coupling elements (7) on the leaf spring arrangement formed by the leaf spring (5) with the two extension arms (6). In addition, the coupling elements (7) are
