The invention provides an eddy current brake for a maglev train, and the brake comprises an eddy current brake electromagnet and a brake air cylinder. The eddy current brake electromagnet is arrangedon the maglev train and is opposite to a guide rail of the maglev train in the horizontal direction; the brake air cylinder comprises a movable component, and the movable component is pushed by air pressure and is in rigid connection with the eddy current brake electromagnet, so that the eddy current brake electromagnet is controllably close to or far away from the guide rail. In addition, the invention further provides a control device for the eddy current brake and the maglev train with the eddy current brake, the transverse stretching and retracting of the eddy current brake of the high-speed maglev train are controlled, and the defect of emergency braking of an eddy current braking system of the high-speed maglev train is overcome, thereby improving the reliability of emergency braking, and adding the parking braking function. The device is simple and reliable in structure and control.
本发明提供了一种用于磁悬浮列车的涡流制动器,涡流制动器包括涡流制动电磁铁和制动风缸,其中:涡流制动电磁铁安装至磁悬浮列车,并且在水平方向上与磁悬浮列车的导向轨道相对设置;并且制动风缸包括可动构件,可动构件由空气压力推动并且与涡流制动电磁铁刚性连接,以使得涡流制动电磁铁可控地接近导向轨道或远离导向轨道。此外,本发明还提供了用于该涡流制动器的控制装置及具有这样的涡流制动器的磁悬浮列车,实现了对高速磁悬浮列车涡流制动器的横向伸缩的控制,并针对高速磁悬浮列车涡流制动系统紧急制动的不足,提高了紧急制动的可靠性、增加了停放制动功能。本发明装置结构与控制简单可靠。
