The invention discloses a power bogie based on a novel motor suspension structure and an upper swing bolster, and belongs to the field of railway vehicle power bogie devices. The power bogie comprises a framework, a wheel set device composed of wheels and axles, an easy-to-withdraw shaft type gearbox, a side beam single-point suspension type motor, the integrated vibration reduction type swing bolster and a secondary suspension system. On the premise that the mounting position and the vibration reduction index of the primary suspension axle box device are ensured, the transverse width size and the turning radius of the whole bogie are effectively reduced, the curve passing capacity of the bogie is further improved, and the annular vibration reduction axle box is convenient to mount, dismount and maintain; and after four fastening bolts are respectively dismounted, the side beam single-point suspension type motor can be directly and independently dismounted from the lower part of the vehicle body through the maintenance trench.
基于新式电机悬挂结构和上置摇枕的动力转向架属于轨道车辆动力转向架装置领域,其包括构架、由车轮和车轴构成的轮对装置、易退轴式齿轮箱、侧梁单点悬挂式电机和集成减振式摇枕及二系悬挂系统。本发明在确保一系悬挂轴箱装置安装位置和减振指标的前提下,有效降低了转向架整体的横向宽度尺寸和回转半径,使该转向架的曲线通过能力获得进一步的提升,环形减振轴箱便于安装和拆卸维修;本发明在分别拆除四个紧固螺栓之后,侧梁单点悬挂式电机可经由检修地沟直接从车体下方单独拆除。
