中车青岛四方机车车辆股份有限公司自主研制的国内首台轨道车辆永磁直驱转向架装车试验成功,填补了我国在直驱转向架技术领域的空白。据介绍,传统的转向架由电机牵引,通过齿轮传动装置驱动,而永磁直驱转向架将永磁直驱电机整体安装在轮轴上直接驱动轮对,省去了中间的齿轮传动环节,具有结构简单、高效节能、运行可靠、噪音低等优点。该新型永磁直驱转向架采用全封闭水冷永磁直驱电机
Qingdao Sifang Locomotive and Rolling Stock Co., Ltd. independently developed by China’s first rail vehicles permanent magnetic direct bogie loading test successfully filled China’s direct-drive bogie technology in the field of blank. According to reports, the traditional bogie traction by the motor, driven by the gear drive, and permanent magnet direct-drive bogie permanent magnet direct-drive motor mounted on the wheel axle directly driven wheelset, eliminating the need for intermediate gear transmission, with Simple structure, high efficiency and energy saving, reliable operation, low noise and other advantages. The new permanent magnet direct-drive bogie with fully enclosed water-cooled permanent magnet direct drive motor
