1990年瑞士ABB公司为美国巴尔的摩制造的城市轻轨车辆为六轴关节车辆。它采用交流异步电机驱动,并具有先进的计算机控制、故障监测和技术诊断系统。该车主要特点如下: 驱动系统由具有GTO可控硅的交流控制三相电机; 转向架上安装两台牵引电机,每台电机通过联轴器驱动减速齿轮机构; 常用制动采用再生制动和盘形制动;紧急制动采用轨磁制动和盘形制动。主要技术参数: 电压(直流 V) 750 轨距(mm) 1435
In 1990, ABB of Switzerland built six-axis joint vehicles for the urban light-rail vehicles in Baltimore, the United States. It uses AC asynchronous motor drive, and has advanced computer control, fault monitoring and technical diagnostic system. The main features of the car are as follows: The drive system consists of an AC-controlled three-phase motor with a GTO thyristor; two traction motors are mounted on the bogie and each motor drives a reduction gear mechanism through a coupling; the regenerative brake Disc brake; emergency brake with magnetic rail brake and disc brake. The main technical parameters: Voltage (DC V) 750 gauge (mm) 1435
