Its three because the inner tube of a tyre 12 is to keep inflating condition in cover tire 10, and the inner tube of a tyre 12 can quick explosion when high pressure is damaged, makes cover tire 10 lose internal pressure in moment, the vehicle during the user is just travelling then can be absorbed in very dangerous situation.

Shortcoming for above-mentioned conventional tire structure, improvement trend is demand with the breakage-proof that improves the Outer Tyre material all at present, though so improvement has its effect, but the inventor is not as limit, and more deep design has more the improvement of intention and effect, in the hope of promoting the practicality of tire construction significantly; Go through repeatedly research and develop, study after, create a kind of inner tube of a tyre, low production cost, safe tire structure-improved of need not using finally.

Primary and foremost purpose of the present utility model is to provide a kind of tire structure-improved that need not use the inner tube of a tyre, and the utility model is that the tire lip inwall at cover tire sets out one deck air tight tyre sidewall indirectly, and this tyre sidewall only engages with the tire lip of cover tire with two lateral margins; Use this kind structure, the utility model can not need use the inner tube of a tyre, so the utility model job procedure can be too complicated difficult, and can not destroy tire construction in handling process, and overall weight more can alleviate.

Secondary objective of the present utility model is to provide a kind of tire structure-improved of low production cost, because the utility model need not use the inner tube of a tyre, so manufacturing person does not need two kinds of different moulds and produces streamline, makes manufacturing cost greatly reduce; In addition, because the inner tube of a tyre is to connect in the form of sheets between the tire lip that is located at cover tire, so the material that the inner tube of a tyre consumes is not high; So the utility model guarantees it is a kind of with low cost, tire structure-improved that product competitiveness is high.

Another purpose of the present utility model is to provide a kind of safe tire structure-improved, the utility model has only air and inner tube free in cover tire, and when the air tight tire is worn by sharp object is prominent during at high pressure, except that cover tire has the space and slowly the gas leakage, this tyre sidewall is explosion fast not, make cover tire can keep the internal pressure of a period of time, and the vehicle of user in just travelling can the safe arrival repair location.

The purpose of this utility model is achieved in that a kind of tire structure-improved, mainly form jointly by members such as cover tire, tyre sidewall and valves, it is characterized in that: this cover tire is the ring-type colloid lamellar body of an outer tool tread, and its truncation surface generally is the Ω font, is provided with thicker tire lip at two times ora terminalis of cover tire Ω font; This tyre sidewall is the elastomeric film of a tool, and is with dual side-edge edge and the sticking mutually driving fit of the tire lip of cover tire; This valve is an air switch that can supply inflation, lose heart, and is that driving fit is installed on the tyre sidewall.

In sum, innovation structure of the present utility model design is to crush easily when being commonly used in the dress inner tube of a tyre and problem that the inner tube of a tyre can instant exploding when being punctured for overcoming; The utility model solution is that the tire lip inwall at cover tire sets out one deck air tight tyre sidewall indirectly, and this tyre sidewall only engages with the tire lip of cover tire with two lateral margins; Use this kind structure, the utility model can be brought into play and need not use the inner tube of a tyre, characteristic that manufacturing cost is cheap, and the problem that the utility model can instant exploding can eliminate the inner tube of a tyre commonly used and be punctured because of the inner tube of a tyre of no easy explosion in the cover tire time; So the utility model is a kind of inner tube of a tyre, low production cost, safe tire structure-improved of need not using really.
