Chevron Springs by HAMM Mount
Rubber chevron springs are the most widely used primary suspension element in modern railway bogie designs worldwide. The V-shaped rubber layer stack provides controlled spring characteristics in vertical, lateral, and longitudinal directions simultaneously, eliminating the need for separate guidance elements. HAMM Mount manufactures chevron springs for metro trains, trams, commuter rail vehicles, mainline passenger coaches, and freight wagons operating across North America, Europe, Asia, and Australia. Our chevron springs are engineered using finite element analysis to optimize rubber layer geometry for each specific bogie platform, ensuring correct static deflection, dynamic stiffness ratios, and fatigue life exceeding 10 million cycles. Every chevron spring leaving our facility is tested for load-deflection characteristics and fire safety compliance per EN 45545-2.
