Abstract
This improved runflat system is formed from a plurality of arcuate sectors, each of said sectors being linked to at least one other sector such that the sectors form a substantially continuous ring around the wheel. The sectors are preferably provided with and joined by integral overlapping and interlocking connector parts positioned at the ends of each sector. No tools or other extraneous hardware is required to join the sectors together and the structure of the connector parts in some embodiments allows rotation around an interconnection rotational axis, such that each sector can be rotated around said interconnection rotation axis with respect to an adjacent sector. In addition, in various optional embodiments, the invention includes connection means that allow rotation between sectors, latching means for holding sectors together, and structure(s) that help to eliminate frictional heating (and concomitant system failure) between the runflat sectors and the tire by making the runflat sectors freely rotating with respect to the tire and/or by providing compensators between sectors and tire that likewise serve to reduce friction and heating.
