The invention provides a transmission mechanism, a bogie and a railway vehicle. The transmission mechanism comprises a motor, a first shaft body, a gearbox, a second shaft body and a connecting part, the first shaft body is connected with the motor; the second shaft body is connected with the gear box; the first shaft body and the second shaft body are in transmission connection through the connecting part; a containing groove is formed in the side, facing the second shaft body, of the first shaft body. The end face, facing one side of the first shaft body, of the second shaft body is located in the containing groove or flush with the end face of the first shaft body. According to the transmission mechanism, the bogie and the railway vehicle, by shortening the transverse distance between the motor and the gearbox, the spatial arrangement relation is improved under the condition that the transmission structure is not changed.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a transmission mechanism, a bogie and a rail vehicle. Background technique [0002] At present, the built-in bogie frame and the primary suspension are arranged on the inside of the wheelset, resulting in a tension in the lateral relationship of the bogie. Due to the high driving power requirement, the size of the motor cannot be greatly reduced. SUMMARY OF THE INVENTION [0003] The invention provides a transmission mechanism, which is used to solve the defect that the transmission system of the existing rail vehicle occupies a large space and cannot achieve a large reduction in size. By shortening the lateral distance between the motor and the gearbox, the transmission structure is not changed In the case of , improve the spatial arrangement relationship. [0004] The invention also provides a bogie, by shortening the lateral distance between the motor and the gear box, im...
