An apparatus for driving electrically a hand-operated wheelchair includes two driving devices, a power supply device, and a control device. Each driving device includes a motor unit provided with a motor shaft and a transmission unit that is adapted to be mounted removably on a respective one of the wheels of the wheelchair so as to transfer rotation of the motor shaft to the respective one of the wheels in such a manner that each of the wheels rotates at a speed smaller than that of the respective motor shaft. The power supply device is adapted to be disposed on a chair frame for supplying electrical power to the motor units. The control device controls speed ratios of the motor shafts of the motor units so as to be adapted to steer the wheelchair. |
