The invention relates to the technical field of bogies of railway traction vehicles, in particular to a bogie device. The bogie device structurally comprises wheels, a steering supporting frame, a slewing bearing, a driving supporting frame, a driving unit, a spring supporting frame, a wheel shaft, a supporting spring and the like, and the bogie device bears all the weight of a vehicle body and transmits traction loads. The bogie device provides power through the driving unit to drive the wheel pair to rotate, and traction force of the wheels and the track is transmitted to the upper vehicle body through the slewing bearing on the steering supporting frame and finally transmitted to the railway vehicle through the upper vehicle body. The bogie device is simple in structural design, large in bearing capacity and better matched with the operation working condition of long-term low-speed heavy-load operation of the railway traction vehicle. The bogie device is compact in structure, small in axle distance, low in manufacturing and maintenance cost and convenient to overhaul.
本发明涉及铁路牵引车辆的转向架技术领域,特别涉及一种转向架装置。其结构包括车轮、转向支撑架、回转支承、驱动支撑架、驱动单元、弹簧支撑架、轮轴、支撑弹簧等,转向架装置承载全部车体重量并传递牵引载荷。转向架装置通过驱动单元提供动力驱动轮对转动,车轮与轨道的牵引力通过转向支撑架上的回转支承传递到上部车体上,最终通过上部车体传递到铁路车辆上。本发明所述的转向架装置结构设计简单,承载力大,更匹配铁路牵引车辆长期低速重载运行的作业工况。其结构紧凑、轴距小、制造、维护成本低、检修方便。
