Multi-chamber tire

A multi-chamber tire comprising an outer layer portion and a flexible ring portion in an annular fashion;

• the outer layer portion is arranged on an external side of the flexible ring portion;
• the flexible ring portion is provided with a chamber arranged around the flexible ring portion;
• wherein the chamber is provided therein with a plurality of partitioned gussets;
• each of the partitioned gussets is arranged to extend along axial and radial directions of the flexible ring portion, and the plurality of partitioned gussets are arranged alternately around the flexible ring portion so as to divide the chamber into a plurality of isolating chambers isolated from each other, wherein, a plurality of isolating chambers abut in order and form one chamber unit, and the plurality of isolating chambers are intercommunicated in the chamber unit;
• and wherein, an inner side of the flexible ring portion is provided with an inner support ring;
• the inner support ring is arranged around the flexible ring portion and provided with a plurality of filling openings which are communicated with the isolating chambers respectively;
• wherein the isolating chamber is provided with a circumferential gusset extends along the radial and circumferential directions of the flexible ring portion, the partitioned gusset and the circumferential gusset are able to withstand dynamic load when at least one of the two adjacent isolating chambers is punctured;
• wherein both top ends of the partitioned gusset and the circumferential gusset are connected to an inner surface of the outer layer portion, and both bottom ends of the partitioned gusset and the circumferential gusset are connected to an inner surface of the flexible ring portion.
