Railway bogie coil spring
As a core damping component of railway freight car bogies, coil springs absorb wheel-rail vibration impacts through vertical elastic deformation and undertake the load transfer function of the car body. Their structure typically adopts a combined form of inner and outer coil springs, which has evolved technologically to form a two-stage stiffness spring system. This configuration establishes a load-bearing mechanism under different loading conditions for empty and loaded cars, ensuring stability and safety during vehicle operation, making it a crucial component for railway freight transportation safety.
