The invention provides a shaft-end power generation system and a shaft-end power generation method for a rail wagon. The shaft-end power generation system comprises a hydraulic transmission system anda power supply system. The hydraulic transmission system comprises a constant displacement pump, a constant displacement motor and an oil supplementing pump. The power supply system comprises an asynchronous generator and a rectification inverter. The constant displacement motor, the asynchronous generator and the oil supplementing pump are connected through a coupler and are in coaxial transmission, wherein the coaxial transmission in both the positive direction and the negative direction can be achieved. The constant displacement pump is installed at the axle end of an axle of the railway wagon and powered by the axle end of the axle. The asynchronous generator and the oil supplementing pump are powered by the constant displacement motor. The rectification inverter is connected with theasynchronous generator. The rectification inverter rectifies and inverts the electricity generated by the asynchronous generator and outputs the electricity to a load. The limit requirement of the rail wagon is met. The constant displacement pump, the constant displacement motor, the oil supplementing pump and the asynchronous generator can work in a two-way rotating mode. The electric power provided in the forward direction is equal to that provided in the reverse direction.
Description
technical field [0001] The present disclosure relates to the technical field of electrical equipment for railway locomotives, in particular to an axle end power generation system and method for railway freight cars. Background technique [0002] Railway freight is an important part of my country's three-dimensional transportation network, which has the advantages of large transportation volume, long distance, low cost, energy saving and environmental protection. At present, there is no conventional power supply system designed for railway freight cars in China, so it is impossible to provide demand for equipment that requires electricity, which seriously restricts the development of automation, informatization, and diversity of railway freight; at home and abroad, especially for high-power electrical equipment There are also few precedents for power supply. [0003] Application No. 200610156743.3 discloses an axle-driven generator for railway passenger cars, etc., which can...
