Abstract
The invention discloses an independent suspension shock absorbing structure for wheels of a scooter. The independent suspension shock absorbing structure comprises a frame. Front wheels and rear wheels are respectively installed at the front end and the rear end of the frame. A cross bar extends along the scooter width direction from the rear end of the frame. The two ends of cross bar are connected with shock absorbers. Each shock absorber comprises a rectangular outer pipe and a rectangular inner pipe. Each inner pipe is arranged in each corresponding outer pipe. Each inner pipe is arranged at an angle of 45 degrees relative to the corresponding outer pipe to enable the edge of the inner pipe to face to the wall of the outer pipe. An elastic rubber pad is arranged between the edge of each outer pipe and the wall of each inner pipe. The cross bar is a rectangular bar and is inserted into the inner pipes. A connecting sleeve is sheathed on each outer pipe. A connecting bar extends rearwards from each connecting sleeve. The rear wheels are connected onto the connecting bars. The rear wheels are independently suspended on the frame through the connecting sleeves and the shock absorbers to enable each rear wheel to be independently suspended on the frame. A spring assembly which is arranged between a seat and the frame in the prior art is abandoned and the shock absorbing effect is remarkable.
