Abstract
The assembly includes a skateboard, a plurality of spaced wheel axles and rotatably secured sets of wheels and elongated resilient suspension frames connected at their opposite ends through housings to the wheel axles and to the underside of the skateboard. The assembly has at least four different shock-absorbing systems. Thus, the frames themselves absorb shock, as do cylinders of resilient rubber or the like set in cups connected to the frames above the wheel axles and bearing against the underside of the board. The wheel axle housings also include resilient dampeners which adjustably restrict steering rotation of the wheel axles and additionally dampen shocks. The frame housing connected to the underside of the skateboard rotatably receives the bases of the frames and adjustably controls that rotation, while providing a shock absorbing function, through the use of resilient bushing around the frame bases. The bushings are adjustably compressible thereagainst by adjustably tightening the frame housing against the underside of the skateboard. The assembly is simple, inexpensive, durable and efficient, imparting greatly improved riding and handling characteristics to the skateboard.
