STEERING BOGIE FOR RAILWAY VEHICLES

摘要

A steering bogie for railway vehicles, having wheel sets installed at front and rear ends thereof . The steering bogie comprises a first link device for hingedly connecting to each other front and rear axle boxes positioned at one side of a bogie frame; a second link device for hingedly connecting to each other front and rear axle boxes positioned at the other side of the bogie frame opposite the first link device; and a torsion bar for interconnecting the first and second link devices located in a staggered manner. Interference force is applied between wheel sets to prevent snake motion of wheels, strength of springs disposed between the bogie frame and the wheel sets is reinforced to improve high speed running stability and followability of the steering bogie, and it is possible to prevent a vehicle body from being excessively deformed and to damp the shock and vibration.
