Abstract
A model vehicle, such as a model electric train, includes a force-isolating drive mechanism. The drive mechanism provides a mechanical linkage and speed reduction between an output shaft of a motor for a model locomotive and its drive wheels, via a gear train. The gear train includes a floating mechanism that permits the model locomotive drive wheels vertical freedom of movement, while still remaining mechanically linked to the gear train. The floating mechanism isolates the model locomotive from forces transmitted from the track bed through the drive wheels, thereby providing a more stable and vibration-free model performance.
