The invention relates to the technical field of locomotives, in particular to a bogie driving system, an electric locomotive bogie and an electric locomotive. The bogie driving system comprises a permanent magnet traction motor, a coupler and a wheel assembly, wherein the permanent magnet traction motor is provided with a center hole and comprises a plurality of hanging pieces capable of being hung on a framework of a bogie; the coupler comprises a hollow shaft, a force transmission disc, a transmission disc, a flange plate, a first flexible sheet assembly and a second flexible sheet assembly.One end of the hollow shaft is connected with the flange, and the other end penetrates through the central hole and is connected with the driving disc; the force transmission disc is fixedly connected with the flange plate through the first flexible sheet assembly and fixedly connected with the permanent magnet traction motor. The wheel assembly comprises a first wheel, a second wheel and an axle, wherein one end of the axle is connected with the first wheel, the other end of the axle penetrates through the hollow shaft and is connected with the second wheel, and the second wheel is fixedly connected with the second flexible sheet assembly on the transmission disc. The bogie driving system is simple in structure, easy to maintain and high in transmission efficiency.
Description
technical field [0001] The disclosure relates to the technical field of locomotives, in particular to a bogie drive system, an electric locomotive bogie, and an electric locomotive. Background technique [0002] In recent years, with the rapid development of the railway transportation industry, electric locomotives for pulling or pushing railway vehicles have also developed rapidly. Among them, the electric locomotive bogie is used to pull the electric locomotive to run on the track, and can play the role of load bearing, force transmission, buffer (walking) and guidance, and the bogie drive system is used to provide power for the bogie. Therefore, the steering The frame drive system is a key system of an electric locomotive. [0003] In the prior art, the structure of the bogie drive system is relatively complex, the maintenance is difficult, and the transmission efficiency is low, which makes it difficult for the bogie drive system of the same specification to take into a...
