The newly designed rubber compression spring reduces spring travel and offers a higher load resistance in the same installation space. It typically consists of a stable lower- and upper plate. Between these, there are multiple rubber layers separated from each other by sheet metal. Depending upon the load type, the compression spring can taper towards the top like a trapezoid. The upper leaf is either bolted to the leaf-spring end or lies loosely upon it. A steel bolt in the rubber compression spring thus provides for high overload protection.
Because of the eccentric positioning, the leaf spring is supported more robustly on the one side than on the other. This counteracts the likewise asymmetric load. This design increases the robustness and, with it, the operational life of the rubber compression spring.
