A spring for use in conjunction with a vehicle, in particular a leaf spring (1), preferably a parabolic spring, has a single-part spring leaf (12) made of steel, in particular spring steel, having a central region (2) and two adjoining edge regions (4a, 4b), wherein the edge regions (4a, 4b) each have an end region (5a, 5b), the end regions (5a, 5b) can each be connected to a chassis in a stationary manner via a rolled eye (11), and the total length of the spring when installed on the vehicle is substantially unchangeable in all load states. In the unloaded state, the spring leaf (12) has two bending sections (13, 14), which each have a curvature with a curvature direction, wherein the curvature directions of the two bending sections (13, 14) are opposed, and the two bending sections (13, 14) merge into each other in the region of a turning point (15). The first bending section (13) is a vertical spring section and runs from the end region (5a) of the first edge region (4a) via the central region (2) to the turning point (15). The second bending section (14) is a horizontal and vertical spring section and runs from the turning point (15) to the end region (5b) of the second edge region (4b).
A spring for use in conjunction with a motor vehicle, wherein the spring is a leaf spring, which has a one-part spring leaf made of spring steel, with a central region and two adjacent edge regions, wherein the edge regions each have an end region, wherein end regions can each be connected to a chassis in a stationary manner via a rolled eye and wherein the total length of the spring in an installed state on the vehicle is substantially unchangeable in all load states, wherein in the unloaded state, the spring leaf has two bending sections, wherein the bending sections each have a curvature with a curvature direction, wherein the curvature direction of the two bending sections is opposed and wherein the two bending sections merge into each other in the region of a turning point, and that the first bending section is a vertical spring section and runs from the end region of the first edge region via the central region to the turning point and the second bending section is a horizontal and vertical spring section and runs from the turning point to the end region of the second edge region.
