Summary: China will be applied to the bogie standard gauge, 25 t axle load, the highest commercial operation speed of 120 km/h each railway speed overloaded trucks. 3 big type bogie structure similar to that of cast steel, but the unique spring plate, such as the shake shake table similar to the passenger car bogie of tilting mechanism, horizontal two levels of stiffness characteristics, greatly increases the vehicle lateral flexibility, has better lateral performance and other advantages. It mainly consists of the wheel and the bearing assembly, bolster and side frame composition, elastic suspension and damping device, foundation braking device, often contact of elastic side bearings, etc.

The main technical parameters:

Axle load (t) 25

Gravity (t) 4.6

Gauge (1435 mm)

Business running speed (km/h) 120

Through the minimum curve radius (m), 100

Wheel diameter (840 mm)
