Axle-end electricity generating apparatus and bogie of railway car

An axle-end electricity generating apparatus and a bogie of a railway car. The apparatus comprises a supporting saddle, a mounting frame, and an electric generator. The electric generator comprises a stator, a rotor, and a housing. The stator is mounted in the housing. The rotor is mounted at an axle end of a vehicle axle. The supporting saddle is provided at the bottom surface thereof with an arced mounting surface fitting a bearing. The mounting frame is provided on the upper end surface with a notch to accommodate a part of the bearing. The supporting saddle and the mounting frame are joined to form an annular outer end surface. The annular outer end surface is provided with a mounting structure used for being fittingly fixed to the housing. When such structure is employed, the supporting saddle and the mounting frame are joined to form an annular structure, which can be fixed on the bearing, at the same time, the annular outer end surface used for mounting the housing is formed on the side, a complete mounting structure for mounting the electric generator is provided, and, when mounting, only the mounting frame needs to be mounted below the supporting saddle to complete the process, thus increasing the convenience of mounting.
