Abstract: A non-pneumatic wheel assembly includes a wheel, a shock absorbing member coupled to an outer periphery of the wheel and absorbing or attenuating noise and vibration due to external shock, a plurality of resilient members arranged around and coupled to an outer periphery of the shock absorbing member in a radial direction and having a plurality of resilient rings that are resiliently deformed in response to an external force, resilient links respectively coupled to the resilient rings to evenly transmit external shock to the resilient rings, rail plates to which sliders formed at both ends of the resilient links are slidably coupled, and a tire having a plurality of coupling grooves formed along an inner periphery such that the rail plates are inserted into the coupling grooves.

Abstract: A new class of non-pneumatic tires is proposed, comprising an exterior torus and an interior torus and in the space between them a waveform undulating ribbon like structure having a constant wavelength and the undulating direction being perpendicular to the plane of rotation of the tire, an example of this class of non-pneumatic tires being where the undulations are in the form of a succesion of semicircular modules alternating one after another in the space between the two toruses;the new class of non-pneumatic tires has a superior capability for fatigue and load compared with the prior art.
