Abstract

The invention provides a driving structure of an electric locomotive. The driving structure comprises a locomotive axle and an axle direct-drive motor, a power shaft of the axle direct-drive motor andthe locomotive axle are the same shaft, the axle direct-drive motor is arranged in the middle of the locomotive axle, and locomotive wheels are respectively arranged at two ends of the locomotive axle; a battery and a driver are further included, and the battery is electrically connected with the axle direct-drive motor through the driver. The driving structure further comprises a position detector, and the position detector is electrically connected with the driver. Compared with an existing internal combustion locomotive and a direct-current motor driven electric locomotive, the electric locomotive provided by the invention has the advantages that the structure is simpler, the reliability is good, pollution and noise are eliminated, and the operation flexibility of the locomotive is improved.

Description

technical field [0001] The invention relates to the technical field of locomotives, in particular to a driving structure of an electric locomotive. Background technique [0002] Due to environmental restrictions, it is difficult to use wired electric locomotives. At present, the locomotives used to transport steel ladles in steel mills and mine docks still use internal combustion locomotives or electric locomotives driven by old-fashioned DC motors. Their common working feature is that the internal combustion engine or DC motor rotates at high speed. After the gearbox decelerates and increases the torque, it is transmitted to the rear axle through the drive shaft to drive the wheels of the locomotive to rotate. [0003] Diesel locomotives are driven by internal combustion engines, and the pollution is serious, especially in the factory building, which will cause great harm to the health of workers; locomotives powered by internal combustion engines and electric locomotives d...
