The invention discloses a railway vehicle built-in bogie transmission device which comprises a gear box, wherein the power input end of the gear box is configured to be of a structure with a cavity, and the power input end of the gearbox is in transmission connection with the output end of the traction motor through an input gear shaft; a diaphragm type coupling and a crowned tooth type coupling are integrated in the cavity; the traction motor transmits power to the output gear through the input gear shaft, the diaphragm type coupling and the crowned tooth type coupling and drives the axle to rotate. The transmission device breaks through the limitation of the structural form of an existing transmission device of the built-in bogie, the installation requirement of the compact space of the built-in bogie can be met; meanwhile, due to the fact that the coupling and the input shaft are integrated together, the displacement compensation function of the coupling can be achieved and the limit rotating speed of the input end bearing selected under the structure can also meet the requirement of a high-speed working condition, and therefore feasibility is provided for design of a high-speed built-in bogie transmission device of 300 km/h or above.

    本发明公开了一种轨道车辆内置转向架传动装置,包括齿轮箱,齿轮箱的动力输入端被配置为具有空腔的结构;齿轮箱的动力输入端通过输入齿轮轴与牵引电机的输出端传动连接;空腔内集成有膜片式联轴节和鼓形齿式联轴节;牵引电机通过输入齿轮轴、膜片式联轴节和鼓形齿式联轴节将动力传输至输出齿轮、并驱动车轴转动。本发明的传动装置突破了既有的内置转向架传动装置的结构形式限制,不仅可以满足内置转向架的紧凑空间的安装要求,同时由于将联轴节与输入轴集成在一起,不仅可以发挥联轴节的变位补偿功能,在该结构下选取的输入端轴承的极限转速也可以满足高速工况要求,从而为300km/h及以上高速内置转向架传动装置的设计提供了可行性。
