Fig. 1～Fig. 3 represents one embodiment of the present of invention.Fig. 1 is the cross sectional drawing that the wheel of tubeless tires of the present invention has been installed.Action Specification figure when Fig. 2 expands for the inner tube of a tyre, Fig. 3 are the Action Specification figure of flexible capsule when destroying.
As shown in Figure 1, on the wheel rim R of bike wheel, be installed with by tire 1 and within it portion the tubeless tires T that sealing element 2 constitutes is housed.Sealing element 2 is in its sealing element main body 2
1The surface of left and right sides sidewall on, along the circumferential direction form two circular protrusions 2 that extend with 360 respectively
2, 2
2, and form a plurality of cylindrical-conical push projection 2 every certain intervals at all wall surfaces upper edge circumferencial direction
3When in energy chamber, expanding in the cover tire 1 of filling aeroseal parts 2, above-mentioned circular protrusion 2
2, 2
2With surperficial closed contact within the cover tire 1, in inside face, the sealing element base portion 2 of tire 1
1Outside the surface and above-mentioned two circular protrusion bars 2
2, 2
2Between form inner aquaseal chamber 7 of filling known aquaseal 8.Aquaseal chamber 7 at least will be towards the tread bar part, along the about half circumference formation in the radial direction outside of sealing element 2.
Wheel rim R has along the ring-type wheel rim base portion 11 of the circumferencial direction extension of the tubeless tires T that the inner tube of a tyre is housed and the flange portion 12,12 of being extended outside radial direction by the axial two ends of wheel rim main body 11, and this flange portion 12,12 keeps the tyre bead part 1 of tires 1
1, 1
1, to tire tube valve 6 at the interior filling air of the inner energy chambers 3 that form of sealing element 2, the tire tube valve hermetic unit of being made by rubber 14 is wrapped in, in the hole of this tire tube valve hermetic unit 14 owing to the tire tube valve installation place 13 of inlaying the place formation on wheel rim body 11 circumference, thereby tire tube valve 6 hermetic is fixed on the wheel rim R.When the sealing element in cover tire 12 expands, because its expansion pressure, with the tyre bead part 1 of tire 1
