Abstract:
1. A transmission device of a vehicle comprising: a vehicle having a shaft, a driven wheel with internal gear teeth defined thereon mounted to a shaft center thereof, and a small driving gear with outer gear teeth defined thereon meshing with the internal gear teeth of the driven wheel, the small driving gear is movable upwardly and downwardly relative to the driven wheel, wherein, depending on the position of the shaft, the small driving gear is located at an offset center of the driven wheel therein to serve as a main source of offset power supply; when the small driving gear, carrying the total weight and load of the vehicle, is rotated forwards and upwards relative to the driven wheel, the outer gear teeth of the small driving gear climb forwards along the internal gear teeth of the driven wheel in internal offset gearing to rotate the driven wheel therewith, converting a gravity force thereof into dynamic driving power.
