The bogie is mainly composed of wheel set, axle box spring suspension device, frame, lower center plate, lower side bearing and so on
The bogie adopts axle box suspension, realizes the elastic positioning of wheel set, and greatly reduces the unsprung mass, thus reducing the dynamic force of wheel and rail and improving the wear of wheel tread.
Gauge：1067mm /1435 mm/ 1600mm
Axle load：21T-45T
Maximum running speed： 80km/h
该转向架主要由轮对、轴箱弹簧悬挂装置、构架、下心盘、下旁承等组成,该转向架采用轴箱一系悬挂，实现了轮对的弹性定位，且极大地降低了簧下质量，从而降低了轮轨动态作用力，改善了车轮踏面磨耗。
