Hourglass springs provide resilient support between the bogie and vehicle body, combining high vertical load capacity with low horizontal stiffness and substantial lateral flexibility. Their tapered elastomer-metal construction produces a progressive spring response, with resistance increasing as compression rises to accommodate changing loads.
The suspension function relies on elastomer deformation and requires no compressed-air supply, offering a compact solution with low maintenance requirements. Manufactured in Germany, these springs can be customised from technical drawings, existing components, physical samples or specific customer requirements.
