几年来Kraus—Maffei交通技术公司进行了铁道机车动车轮对径向可调的先进走行装置的设计开发,在Kraus—Maffei公司广泛预试验的基础上,联邦研究技术部(BMFT)决定开发、制造和试验现代高速通用电力机车的轮对径向可调动力转向架,与德国联邦铁路(DB)合作将1台BR120型原型机车作为试验车,计划的目的是证实径向可调轮对相对传统二轴走行装置的优点,这些优点是:
Over the years Kraus-Maffei Transportation Technologies has designed and developed a radial-adjustable, advanced walkway for locomotive wheels. Based on extensive pre-tests by Kraus-Maffei, the Federal Research and Technology Department (BMFT) decided to develop, manufacture And the wheel-radial adjustable power-driven bogie used to test modern high-speed general-purpose locomotives. In cooperation with the German Federal Railroad (DB), a BR120 prototype locomotive was used as a test car. The purpose of the plan was to confirm the relative tradition of the radially adjustable wheelset The advantages of two-axis travel device, these advantages are:
