Non-inflatable tyre

The utility model provides a non-inflatable tyre and relates to the field of tyres. The non-inflatable tyre comprises a tread, a tyre main body and a reinforced shearing belt, wherein the tyre main body comprises an outer-side circular ring part, an elastic connecting part and an inner-side circular ring part which are integrally formed, wherein the outer-side circular ring part and the inner-side circular ring part are concentric and are connected by virtue of the elastic connecting part; the reinforced shearing belt is clung between the tread and the tyre main body; the elastic connecting part comprises at least one spoke pair, each spoke pair comprises a left arc-shaped spoke, a right arc-shaped spoke and a connecting plate, the left arc-shaped spoke and the right arc-shaped spoke are symmetric regarding a first longitudinal section of the outer-side circular ring part, and respectively extend to the radial inner side of the outer-side circular ring part from the radial outer side of the inner-side circular ring part; one second longitudinal section of the left arc-shaped spoke and the outer-side circular ring part is tangent to a left tangent line, and a third longitudinal section of the right arc-shaped spoke and the outer-side circular ring part is tangent to a right tangent line. According to the scheme, the supporting force of the tyre to a load is improved, the tyre is prevented from flexing during contracting, and the durability and the service life of the tyre are improved.
