• Bogie technical characteristics
• The bogie structure can adjust slant of the body(passenger car), difference of the wheel load.
• Material of the each part meets railway industry standards and could use alternative material according to different regions and national standards
• Standard parts and general parts are used for each part and should be interchangeable.
• Design life is over 3 million km or 30 years
• Noise reduction measures(passenger car) for major components
• Different types of wheels can be used such as cast steel wheels, rolling forging wheels, elastic wheels
• The preliminary suspension is a metal rubber spring (passenger car), or a cylindrical coil spring with a vertical hydraulic shock absorber (passenger car), and the Secondary suspension is an air spring with an anti-roll torsion bar (passenger car)
• The mainframe is evaluated by finite element stress analysis and fatigue strength; Manufacture, welding follow railway standards, and with good corrosion resistance.
• Traction and transmission device are safe and reliable after simulated operation test.
• Easy to install, disassemble and have good maintainability.
