HIGH-SPEED RAILWAY WAGON BOGIE CAPABLE OF INDEPENDENT POWER GENERATION

Title:

HIGH-SPEED RAILWAY WAGON BOGIE CAPABLE OF INDEPENDENT POWER GENERATION

Document Type and Number:

WIPO Patent Application WO/2021/120622

Kind Code:

A1

Abstract:

A high-speed railway wagon bogie capable of independent power generation comprises a wheel and axle assembly (1), a framework (1.1), a journal box suspension device (3), a bolster (4), a foundation brake rigging (5), a side bearing (6), an empty and load adjustment device (7), and a central suspension device (8), and further comprises a longitudinal traction device (9), a vertical damping device (10), and a lateral damping device (11). An axle end power generation device (13) is coupled to an axial outer end of the wheel and axle assembly (1). A rotor portion of the axle end power generation device is coupled to an end bearing (1.1) of the wheel and axle assembly by means of an axle end bolt, and a stator portion is coupled to a mount of the journal box suspension device. The bogie can supply power to a railway wagon. In addition, the bogie is designed to be wear resistant, and comprises a large number of rubber elements and hydraulic damping devices, thereby improving lateral stability, straight motion stability, and curve passing performance of running wagons, allowing the bogie to be adapted to a wide range of routes, meeting operational requirements of a speed under 160 km/h, and reducing bogie application and maintenance workloads.
