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.

Number of spring set and main parameters are marked on the copper sheet, which is set on the spring. Samples were approved in March, 2002. From April of 2002 to now, springs have been exported in batches to
