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: Provided is a non-pneumatic wheel (100) for a vehicle, and a wheel (100), suspension (200; 200-1), and tire (300) used therein that are capable of ensuring driving stability because there is no air chamber between a wheel (100) and a tire (300) to blowout. They are also capable of ensuring good road holding, preventing standing waves, reducing brake fade and cornering force, providing good handling and ride comfort, staying quiet when rolling, and are economical and environmentally friendly.
