SS_4型电力机车是为我国铁路干线新设计的重型货运机车,其设计研制工作己逐步开展。现就该车设计制造的几个主要问题谈一点不成熟的设想、仅供从事该车设计与工艺工作的领导与工作者参考,错误与不妥之处望同志们指正。一、关于提高粘着性能SS_4型电力机车作为干线大功率重型货运机车,对该车的主要要求是粘着性能。据任务书规定,该车持续制功率为6400瓩,持续制牵引力不小于44吨(每轴不小于5.5
SS_4 electric locomotive is a newly designed heavy-duty freight locomotive for China’s railway trunk line. Its design and development work has been gradually carried out. Now on the car design and manufacture of several major issues to talk about a little premature vision, only engaged in the car design and technology work of the leaders and workers reference, mistakes and inappropriate look at the comrades correct. First, on improving the adhesion performance SS_4 electric locomotive as a trunk high power heavy cargo locomotive, the main requirement of the car is the adhesion performance. According to the mandate book, the car continued to make power of 6400 持, sustained traction of not less than 44 tons (not less than 5.5 on each axis
