为贯彻执行苏共二十七次代表大会的精神诺瓦切尔斯克工厂与全苏电力机车制造科学研究所共同研制了一种带有十二个轮对的ВЛ85型干线交流机车。在研制机车的过程中,对一些设计、工艺及成本问题展开了广泛的讨论,其目的在于为机车走行部分,牵引电路、自动控制、设备布置选择合适的技术方案,以改善牵引动力性能,减少电力机车的单位材料用量以及制造和修理的劳动量,提高机车的工作可靠性,使之能在摄氏零下60~0c的贝尔加——阿木尔干线上使用。
In order to carry out the spirit of the Twenty-seventh Congress of the CPSU, Novartiskerk Factory and All-Electric Locomotive Manufacturing Science Research Institute jointly developed a 12-wheel mainline AC locomotive ВЛ85. In the process of developing locomotives, extensive discussions have been made on some design, process and cost issues with the aim of selecting appropriate technical solutions for running parts, traction circuits, automatic control and equipment layout of locomotives to improve traction power performance and reduce The amount of unit material used for electric locomotives, as well as the amount of labor required to manufacture and repair the locomotives, will improve the reliability of locomotives and enable them to be used on the Belga-Amur Route at 60 ° C to 0 ° C.
