Abstract
An independently controllable transmission mechanism with an identity-ratio series type includes a first planetary gear train and a second planetary gear train mechanically connected therewith. The transmission mechanism has a power output end, a transmission control end, a power input end and a free transmission end. The power output end and the transmission control end are provided on the first planetary gear train and the second planetary gear train, respectively. The power input end is provided on the first planetary gear train or the second planetary gear train while the free transmission end is provided on the second planetary gear train or the first planetary gear train. The transmission control end is operated to freely shift the free transmission end as a power input end or a power output end.
