发明名称	BOGIE FOR RAILWAY VEHICLE
摘要	PROBLEM TO BE SOLVED: To provide a bogie for a railway vehicle capable of restraining wheel load unbalance. SOLUTION: Respective hydraulic cylinders 25 are provided between bogie frames 11 of the bogie 10 and respective axle springs 23. Pressure receiving chambers in the respective hydraulic cylinders 25 are communicated with each other through communicating pipes 27, whose junction is equipped with a valve 29. In a hydraulic cylinder for a wheel with a larger wheel load, the bogie 10 causes higher pressure than those of the hydraulic cylinders 25 for the other wheels, so that the pressure oil flowed from the hydraulic cylinder flows into other hydraulic cylinders through the communicating pipes and the pressures in the pressure receiving chambers of the respective hydraulic cylinders are uniformed. Then, the wheels are pushed downward through the oil cylinders, thus compensating for releasing of a wheel load in the wheels. COPYRIGHT: (C)2006,JPO&NCIPI
