Abstract
A suspension spring unit for a vehicle chassis can be positioned between a vehicle body and a wheel carrier. In some examples, the suspension spring unit may comprise at least four fiber composite leaf springs. The leaf springs may have a flat extent between two spring ends and may be connected to each other in pairs at a distance from each other. End connecting elements disposed over the spring ends may receive the spring ends so as to form at least two leaf spring pairs arranged in series. The leaf spring pairs may be connected to each other by central connecting elements via central regions between the spring ends of the leaf springs.
