| 20110253464 | SUSPENSION SYSTEM FOR ELECTRIC WHEELCHAIR - A suspension system for an electric wheelchair is revealed. A pivot on a front end of a wheelchair frame pivotally connects a front wheel frame and a drive set frame. A front suspension system is disposed between the front wheel frame and a drive set frame. The front wheel frame is assembled with front wheels, the drive set frame is disposed with a drive set and a drive wheel is arranged at a power output end of the drive set. Moreover, an auxiliary suspension device is arranged between the drive set frame and the frame while a rear end of the frame is disposed with rear wheels. Thereby the electric wheelchair has good stability and slip-resistance, not easily overturned or slid by interaction between the front and the auxiliary suspension devices while driving through concave surfaces or convex surfaces. Therefore the safety of users seated in wheelchairs is assured. | 10-20-2011 |
