摘　　要：将FXD2B型电力机车轴重由原来“30 t、27 t”2种轴重向下覆盖到“30 t、27 t、25 t”3种轴重,解决机车在普速线路开行时集中载荷25 t限制的问题。同时,进一步实现互联互通,提升部件简统化、智能化水平,使FXD2B型电力机车能够更好地满足中国铁路牵引需求。The operation range of FXD2B electric locomotives is extended from the original two kinds of axle loads "30 t, 27 t" to three kinds of axle loads "30 t, 27 t, and 25 t", which solves the problem of concentrated load limit of 25 t when the locomotive operates on ordinary speed lines. At the same time, through further achieving connectivity, improving simplification and unification of components and intelligent technology, the FXD2B electric locomotive can better meet the traction needs of China's railways.
