181·2为两种电流制客、货两用电力机车,共25台,运行在与法国和卢森堡相连接的电气化线路上。181·2机车是在采用电阻制动的两台181°机车和采用再生制动的两台181~1机车进行比较试验的基础上设计、制造的。该机车的特点是簧下重量轻,只有轮对本身是簧下重量;牵引电机的重量集中在转向架中心线上;转向架轴距短;轮对具有一定的横向移动量。转向架为焊接结构,轮对和转向架之间采用圆簧和双扭线轴箱拉杆悬挂,车体通过
181.2 are two electric current passenger and cargo electric locomotives with a total of 25 units operating on electrified lines connected to France and Luxembourg. 181.2 The locomotive was designed and manufactured on the basis of a comparative test of two 181 ° locomotives with resistance braking and two 181-1 locomotives using regenerative braking. The locomotive is characterized by unsprung weight, only the wheel itself is unsprung weight; traction motor weight concentrated in the bogie center line; bogie wheelbase is short; the wheel has a certain amount of lateral movement. The bogie is a welded structure, the wheelset and the bogie are suspended by a round spring and a double twist line box, the vehicle body passes
