Primary conical springs provide resilient support between the bogie frame and the wheelset or axle assembly. Their elastomer-metal construction carries loads, reduces the transmission of shocks and vibration, and controls movement within the primary suspension. The conical shape creates a progressive spring response, with resistance increasing as the spring compresses, allowing a compact design to accommodate varying loads.
Manufactured in Germany, these springs are available in various sizes and technical configurations. Custom versions can be produced from technical drawings, existing components, physical samples or specific customer requirements.
