Problems solved by technology

When a foreign object gets into the tire, the airtightness is destroyed and cannot work
The tubeless structure widely used on automobiles and motorcycles can maintain a certain gas pressure for a period of time after the tires are punctured, but on bicycles, because the tires are in the shape of narrow and thin rings, the tires will be deformed due to expansion after inflation , its rim cannot seal with the rim, so it cannot be used

Embodiment Construction

[0010] As shown in the figure, the wheel structure used in the embodiment is a rim 5 and a pressure plate 6 formed by rolling an iron plate, and a spoke plate 7 made by stamping an iron plate is welded on the rim 5 and the hub to form a rim, and the pressure plate 6 rolls After compression molding, the sections are welded on the inner bottom of the rim 5, and there are gaps at the two edge positions of the rim 5 and the pressing plate 6.

[0011] Sealing ring 3 is formed on the outer edge of tire 1, is semicircular shape, and sealing ring 3 interior is embedded with cord 2, to increase its strength, prevent expansion and deformation after inflation.

[0012] The inner side of the rim 5 is rolled with a slot 4, the shape of the slot 4 matches the sealing ring 3, and the slot 4 and the sealing ring 3 are fastened together.

[0013] The skirt 8 along the edge of the tire 1 is embedded in the gap between the pressure plate 6 and the rim 5 .

[0014] After inflation, the skirt 8 o...

Abstract

The invention relates to a wheel of bicycle without inner tube, which comprises a rim formed by hub, disc and ring; and a tyre, wherein the outer edge of wheel is processed with a semi-circular sealing ring; the inner side of ring is processed with clamp groove; the clamp groove is clamped with the sealing ring; the inner bottom of ring is mounted with a compress plate; the edge of the opening of tyre is embedded into the slit between the compress plate and the ring; the inner part of sealing rind is embedded with curtain line. Since the ring and tyre are clamped by clamp groove and sealing rind, and the edge of tyre is embedded into the slit between compress plate and the ring, the aerated tyre will not expand and deform, with better sealing effect and the application in bicycle.

Description

technical field [0001] The invention relates to a bicycle component, which is a bicycle wheel. Background technique [0002] The tire of existing bicycle is made up of wheel rim, inner tube, cover tire, and the inner tube of a tube plays gas storage effect, and cover tire plays shaping and ground contact transmission effect. When a foreign object gets into the tire, the airtightness is destroyed and cannot work. The tubeless structure widely used on automobiles and motorcycles can maintain a certain gas pressure for a period of time after the tires are punctured, but on bicycles, because the tires are in the shape of narrow and thin rings, the tires will be deformed due to expansion after inflation , its rim cannot seal against the rim and cannot be used. Contents of the invention [0003] The object of the present invention is to provide a tubeless wheel used on bicycles, which can maintain a certain air pressure for a period of time after the bicycle tire is punctured,...
