Summary: China railway axle load 27 t, commercial operation speed of 100 km/h each rail overloaded trucks. Combined the technology of the swing motion bogie side frame swing a series of axle box flexible positioning technologies and low power bogie, wheel/rail lateral, vertical movement strength is low, wheel/rail wear is small. With low power, quasi radial, no welding, light wear. Is mainly composed of bolster and side frame form, the wheels on the composition, rolling bearing unit, axle box linkage, the central suspension and damping device, the bogie brake device, swinging device and the elastic side bearing, etc.
