发明名称 Model locomotives
摘要 In a model of a steam locomotive having two independent sets of driving wheels, the single electric motor for driving the model is coupled to the two sets of driving wheels via a differential gear. The latter allows the two sets of driving wheels to alter their angular positions relative to each other, owing to track irregularities and other causes, and thereby enables the model to operate more realistically.
