Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of toy models, in particular to an electric train model. Background Art
[0002] Traditional model trains primarily transmit power between the drive wheels and the drive motor via connecting rods and gear-screw assemblies. To increase speed and maintain power output, some current model trains often use dual-axis motors to drive two drive wheels to control the train's movement.

Furthermore, in model trains with dual-axis motors, the output shafts on both sides may have different rotational forces during turns, which can also affect the motor's service life.
