Abstract

The present disclosure proposes an axle end power generation system and method for railway freight cars, including a hydraulic transmission system and a power supply system; the hydraulic transmission system includes a quantitative pump, a quantitative motor, and an oil charge pump; the power supply system includes an asynchronous power generation system motor and rectifier inverter; the quantitative motor, asynchronous generator, and oil charge pump are connected by a coupling and coaxially driven, with positive and negative directions; the quantitative pump is installed on the shaft of the axle of the railway freight car The asynchronous generator and charge pump are powered by a quantitative motor; the rectifier inverter is connected to the asynchronous generator, and the electricity generated by the asynchronous generator is rectified and inverted and then output to the load. The disclosure complies with the limit requirements of railway locomotives; the quantitative pump, the quantitative motor, the fuel pump and the asynchronous generator can all rotate in two directions, and the power provided in the forward direction and the reverse direction is equal.

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...
