随着铁路运输事业的不断发展,列车的双机及多机牵引势在必行。SS_4型电力机车是由两节完全相同的四轴机车用车钩及车棚连结而成的八轴重型货运机车。既可在其中任一节车的司机室对全车进行统一控制,也可将两节车分开作为四轴机车独立运用。因而其制动系统共有:两单元各自能独立的制动机系统;每单元只有一台空气压缩机作为机车制动系统及气动电器的控制风源。
With the continuous development of railway transportation, the double and multi-machine train traction is imperative. The SS_4 electric locomotive is an eight-axle heavy goods freight locomotive which is made up of two identical four-axle locomotive hooks and sheds. Both in one of the car driver’s cab for unified control of the entire car, but also can separate the two cars as a separate use of four-axis locomotive. Therefore, the brake system has a total of two units each having a separate brake system, and only one air compressor per unit is used as a control air source for the locomotive brake system and the pneumatic apparatus.
