Abstract:
A driving device on a wheel inner circumferential edge comprises: a stationary shaft (202); and one or two transmission shafts (201). One end or an inner end of the transmission shaft is provided with a power input device cooperating with a transmission system of a car body. The other end of the transmission shaft extends into a wheel (101) and is provided with a power output device. An inner circumferential surface of a rim of the wheel is provided with an inner gear ring (102) cooperating with the power output device. A force application point of the driving device is set on an inner circumferential edge of the wheel, namely the inner gear ring, and the driving device is always positioned above the force application point, thereby extending a power arm, and saving energy.
