The invention discloses a bogie based on a flexible interconnection framework and an upper swing bolster, and belongs to the field of railway vehicle power bogie devices. The bogie comprises an axle box, a wheel set device composed of wheels and axles, a transverse and longitudinal integrated flexible interconnection framework, 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. The damping requirement for the whole framework is greatly reduced, and the effects of reducing the number of parts and the failure rate, releasing the layout space and maintenance operation allowance of a motor and a gearbox, simplifying the framework size and simplifying the manufacturing process are achieved; According to the invention, after fastening bolts of four motor flexible suspension rubber nodes and fastening bolts of side beam end motor suspension rubber nodes are respectively dismounted, the side beam single-point suspension type motor can be directly and independently dismounted from the lower part of a vehicle body through a maintenance trench.

    基于柔性互连构架和上置摇枕的转向架属于轨道车辆动力转向架装置领域,其包括轴箱、由车轮和车轴构成的轮对装置、横纵一体式柔性互连构架、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。本发明大幅降低了对构架整体的减振需求,起到减少部件数量和故障率、释放电机和齿轮箱布局空间和检修操作余量,精简构架尺寸、简化制造流程的效果;本发明使得在分别拆除四个电机柔性悬挂橡胶节点和侧梁端电机悬挂橡胶节点的紧固螺栓之后,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。
