The device has a driving motor (5), two drive wheels (1,2), a steering device and fastening parts for docking at a wheelchair. The two drive wheels are positioned commuting around a floating axle (180) and are interconnected by a differential. The floating axle runs perpendicularly to the axis of rotation of the two drive wheels in a plane. The drive wheels are rigidly connected with the driving motor. |
