Suspension Systems

Primary Springs Overview
Developed in collaboration with the customers to meet specific requirements, primary suspension systems aptly tackle the complexity of wheelset guidance and bogie suspension. By assuming complete responsibility for engineering and project management, we are able to achieve economic, logistical and technical synergies. Primary Springs Conical Springs
Conical Springs permit a large variation in adjustable vertical and horizontal stiffness within a confined space. They often eliminate the need for any auxiliary damper. Chevrons
Primary Chevrons are reliable spring elements in primary and secondary suspensions with decades of worldwide service in various railway vehicles. Primary chevrons are maintenance free, have a compact design and are available in a spectrum of spring designs. Layer Springs
Primary Layer Springs ensure maintenance- free bearing of primary and secondary suspension systems. Hydraulic Springs
Consists of a conical spring and an integrated hydraulic damping system that does away with the need for a primary shock absorbers. www.enidine.com • www.koni-enidine-rail.com • www.koni.com 9
