许多铁路准备在不久的将来提高行车速度到160公里/小时。为此,需要进一步采用新技术设备,首先是制动设备。在160公里/小时及其以上的高速行车中,制动系统对于保证营运安全具有重要意义。车辆制动设备必须能充分满足车辆在运行速度、制动距离和行驶的坡道坡度方面的要求。目前干线铁路远距信号允许可行的制动距离为1000米。制动机的效率越高,在平道和坡道上可能运行的速度也愈高。一般闸瓦制动机的功率,在160公里/小时的速度下,不能满足制动过程的要求。使用盘形制动机,无论在160公里/小时时的停车制动,或是在坡道上的持续制动,都能满足制动距离和散热方面的要求。它的功率大,较闸瓦为优,最适于高速行车。
Many railroads are going to increase their driving speed to 160 km / h in the near future. To this end, the need for further use of new technology and equipment, the first brake equipment. Braking systems are important in ensuring operational safety at high speeds of 160 km / h and above. Vehicle braking equipment must be able to adequately meet the requirements of the vehicle in terms of operating speed, braking distance and running ramp. At present, the possible braking distance allowed by the long-distance signal of the trunk railway is 1000 meters. The higher the efficiency of the brake, the higher the speed at which running and ramps may operate. The power of a typical brake shoe brake can not meet the requirements of the braking process at a speed of 160 km / h. The use of a disc brake, braking at 160 km / h, or continuous braking on the ramp, meets braking distances and cooling requirements. Its power, better than the brake shoe, the most suitable for high-speed traffic.
