摘要：
A vehicle spring for a spring system, includes a spring body (20) and is produced, in particular rolled, from a profiled bar (1) made of a flat steel bar, in particular spring steel, in a hot deformation process. The profiled bar (1) or the spring body (20) has at least one material recess (6) which is provided over the length of the profiled bar or the spring body at least in some regions. The cross-sectional shape of the profiled bar (1) can be the same over the entire length of the profiled bar, whereas the cross-sectional shape in the spring body (20) can vary over the length of the spring body.
