近 30年来 ,我国铁路技术取得长足的进步。尤其是近年来 ,随着旅客列车的提速 ,势必促使货物列车提速 ,才能提高运能。货物列车提速的关键技术是转向架的性能和制动机的性能。要提高货物列车运行速度 ,就要提高与运行速度相适应的列车制动力。除新造货车可以采用钩缓、转向架、
In the past 30 years, China’s railway technology has made great strides. Especially in recent years, with the acceleration of passenger trains, it is bound to speed up cargo trains in order to increase transport capacity. The key technologies for speeding freight trains are the performance of the bogie and the performance of the brake. To improve the speed of cargo trains, it is necessary to improve the train braking force that is compatible with the running speed. In addition to newly built trucks can be hook slow, bogies,
