目前,我国驼峰溜放作业中的手闸制动,绝大部分均为铁鞋制动所代替,铁鞋制动虽较手闸制动优越,但仍然存在着很多问题,如:对编组线钢轨的磨耗日趋严重;对车轮的擦伤进而影响车辆的走行性能,对车辆走行部分的损坏(燃轴事故等)日益增多;高速溜放作业安全无保障等等。为了解决铁鞋制动所带来的上述问题,世界各国均 At present, most of the handbrake braking in the hump sliding operation is replaced by the iron brake, although the braking of the iron shoe is superior to that of the hand brake. However, there are still many problems such as: Rail wear more and more serious; abrasion on the wheels and thus affect the performance of the vehicle running on the running part of the vehicle damage (burning shaft accident, etc.) increasing; high-speed slip unsecured operation and so on. In order to solve the above problems caused by iron brake, all countries in the world
