Abstract
A transmission unit includes a main gear and driving power is transmitted to the main gear through a first driving unit, then further transmitted to an inner ring gear through a planetary gear. The power of the inner ring gear is transmitted to a driving element for driving a wheel through an unidirectionally second driving unit. The driving element may rotate independently, while the inner ring gear and the planetary gear will not be driven by the driving element.
