The invention discloses a railway vehicle, a bogie thereof and a detection device for the bogie. The bogie comprises a framework, an axle, wheels, an axle box, a gear box, a first coil, a second coil,stress detectors, a data collector and a transmitting antenna. The first coil is arranged on the framework, the axle box or the gear box, the second coil is arranged on the axle or the wheel, and thesecond coil is coupled with the first coil. And the stress detectors are arranged on the wheels. And the data collector is arranged on the axle or the wheel, is electrically connected with the secondcoil and is connected with the stress detectors. The transmitting antenna is arranged on an axle or a wheel, the transmitting antenna is electrically connected with the second coil, and the data collector is connected with the transmitting antenna. The bogie has the advantages of high wheel and axle strength, high safety and the like, the wheel-rail acting force can be calculated by measuring thestress of the wheel spoke plates, and then railway vehicle operation safety parameters such as the wheel derailment coefficient and the wheel load shedding rate are obtained.
本发明公开了一种铁路车辆及其转向架以及用于转向架的检测装置。所述转向架包括:构架、车轴、车轮、轴箱、齿轮箱、第一线圈、第二线圈、应力检测器、数据采集器和发射天线。第一线圈设在构架、轴箱或齿轮箱上,第二线圈设在车轴或车轮上,第二线圈与第一线圈耦合。应力检测器设在车轮上。数据采集器设在车轴或车轮上,数据采集器与第二线圈电连接且与应力检测器相连。发射天线设在车轴或车轮上,发射天线与第二线圈电连接,数据采集器与发射天线相连。该转向架具有车轮和车轴的强度高、安全性高等优点,能够通过测量车轮辐板的应力,推算出轮轨作用力,继而得出车轮脱轨系数、轮重减载率等铁路车辆运行安全性参数。
