为了解决旅客列车采用电空制动时,需要在机车上安装控制器、车辆间用五芯控制电缆以及改造制动阀等问题,铁道部科学研究院机辆所研制了一种新型列车载波制动装置。在对现有机车、客车制动系统不改动的情况下,只增加信号转移装置,由空气制动信号转换成电信号,通过列车广播线传递,实现列车前后同步制动。具有结构简单、投资少、可靠性强、缩短列车制动距离等优点,为我国旅客列车提速、扩编创造了良好的条件。
In order to solve the problem that passenger train adopts electro-pneumatic braking, it is necessary to install a controller on a locomotive, a five-core control cable between vehicles and a modification of a brake valve. A new train carrier system is developed by the Research Institute of the Ministry of Railways Moving device. In the existing locomotive, bus braking system does not change the case, only increase the signal transfer device, the air brake signal into an electrical signal, through the train radio transmission, to achieve synchronous braking before and after the train. Has the advantages of simple structure, less investment, high reliability, shorten the train braking distance, etc., for our country passenger train speed, expansion has created good conditions.
