Product Description
Product Overview
Chevron spring serves as a primary axle spring in railway systems, offering significant advantages including lightweight construction, simple structure design, high-frequency vibration absorption, and effective noise reduction. These springs are commonly implemented in modern railway coaches for optimal performance.
When installed on axle boxes at an angle, chevron springs require precise dimensional and hardness control to ensure proper frame installation height and safe bogie operation. Strict quality control measures are essential for all primary suspension components.
