The present invention relates to a suspension structure is simple to a wheelchair, which structure comprises a frame (10), two drive units (20), two front units (40), two dampers before (50), two units anti - turning (60) and two shock absorbers rear (70). When the front suspension arm (42) to bring the front guide wheels (41) to pivot, the torsion springs (43) can produce a reaction force in order to prevent the frame (10) to turn, thereby improving the safety. When the suspension structure passes over a road uneven irregular, the dampers before (50) and rear (70) may weaken the shocks imposed on the frame (10), thereby improving the comfort of the seat.
