本文主要阐述选用和评价减速器的原则,对目的制动和间隔制动减速器的不同要求,车辆减速器的性能与测试。同时对我国现有车辆减速器的技术经济指标进行了分析与比较。建议我国铁路编组站应以发展液压重力式减速器为主。并提出在我国已鉴定的四种车辆减速器中,以7501型车辆减速器更适于在编组线內作目的制动用。
This paper describes the principle of selection and evaluation of the reducer, the purpose of the brake and the interval brake reducer different requirements, the performance of the vehicle reducer and testing. At the same time, the technical and economic indexes of the existing vehicle reducer in our country are analyzed and compared. It is suggested that China’s railway marshalling yard should mainly develop the hydraulic gravity reducer. And put forward in our country has identified four kinds of vehicle reducer, 7501-type vehicle reducer is more suitable for braking purposes in the marshalling line.
