Coil Spring

We are offering k6 bogie spring is the key part of bogie, each vehicle consists of 24 outer round springs 1, 4 outer round springs 2, 28 inter round springs, 8 shock absorber outer round springs and inter round springs, the fatigue life reaches to 3 million times and above. K2 bogie spring, the standard used q/qc35-095-2000, intermediate frequency faradism heating device to achieve a rapid heating, effectively reduced the spring surface oxidation and decarburization.
fatigue life is up to 2.6 million times. Main technical parameters: outer spring: od φ 287.6, material diameter φ 36.3, free high-253.5 inner spring: od φ 200, material diameter φ 26.5, free high-253.3 the spring equipped bogie passenger cars with a top speed of 300 km / h it is the key part of bogie, used in bogie passenger train with the max speed 300km/h.
