摘　　要：介绍一种单节八轴交流传动电力机车四轴转向架,该转向架采用B_0+B_0-B_0+B_0轴式以及三系悬挂方式。详细说明了转向架构架、牵引装置、轮对驱动系统和悬挂装置等主要结构部件。该机车具有粘着重量大,曲线通过性能好,轮轨磨耗小等优点。R300m小半径曲线通过时,机车导向轮对轮轴横向力及导向轮轮缘磨耗因子相对2C_0机车减小35%。可满足我国120km/h速度等级的万吨重载货运运输牵引的需要,尤其对曲线多、半径小的山区线路,更能发挥其独特优势。A four-axle bogie was introduced for an eight-axle AC drive electric locomotive which has arranged B_0＋B_0-B_0＋ B_0 and used the mode of three suspensions. The detailed structures of bogie frame,traction device,the drive system and the suspensions were described. The locomotive holds the characteristics of large adhesive weight and good curve passing performances. The wheelset lateral force,wheels guide force and the wheel flange wear index are reduced by 35% relative to the 2C_0 locomotive with the same maximum speed and axle-load when passing the curve of R300. One eight-axle locomotive can meet the traction of the heavy haul freight train with ten thousand tons at the speed grade of 120 km/h in our country. Especially in the mountain area with plenty of small curves,this locomotive can give full play to its particular advantages.
