开发了一种适合于350km/h高速运行的新型动力转向架。为了保证良好的运行稳定性和小的轮轨间导向力,应用了轻型结构原则。空心轴驱动和圆盘制动系统,随着运行状态的要求,它们既可以与机车车体连成一体,又可与转向架构架连成一体(可以相互转换连接的驱动装置重量——缩写为“UmAn”)。为了适于高 Developed a new type of power bogie suitable for high speed operation of 350km / h. In order to ensure good running stability and small between the wheel and rail steering force, the principle of light structure is applied. Hollow shaft drives and disc brake systems, which can be integrated with the body of the rolling stock and with the bogie frame as the operating conditions require (weight of the drive that can be changed over to one another - abbreviated as “UmAn”). In order to fit high
