Embodiment 1

[0019] figure 1 It is a schematic diagram of the cross-sectional structure of the bead part of the tubeless bias tire in this example. There is a bead wire 5 inside the bead part of the carcass. There are 4 places of the fetal toe and outside the mouth wrapping cloth 1, there is a fetal toe wrapping cloth 3, and outside the mouth opening cloth 1 and the fetal toe wrapping cloth 3, there is a cover for completely covering the mouth opening cloth 1 and the fetal toe wrapping cloth 3 Sealing strip 2. The outer end of the fetal toe wrap 3 is aligned with the center of the bead steel wire 5 in the carcass, and is closely attached to the outer surface of the slit wrap 1 and the fetal toe 4, and the other end bends and extends to the inner side of the carcass. The slit wrap 1 in this example is nylon monofilament cloth, the toe wrap 3 is canvas, and the width of the toe wrap 3 is 30 mm.

Embodiment 2

[0021] figure 2 It is a schematic diagram of the cross-sectional structure of the bead part of the tubeless bias tire in this example. There are two bead wires 5 in the bead part of the carcass. There are 4 fetal toe coverings and 1 outside the mouth wrapping cloth 3, and there is a fetal toe covering cloth 3 outside the slit opening 1 and the fetal toe covering cloth 3. Sealing strip 2. The outer end of the fetal toe cloth 3 is aligned with the center of the innermost bead wire 5 in the carcass, and is closely attached to the outer surface of the sub-mouth cloth 1 and the fetal toe 4, and the other end is curved and extended to the inside of the carcass . The slit wrap 1 in this example is nylon monofilament cloth, the toe wrap 3 is canvas, and the width of the toe wrap 3 is 40mm.

Embodiment 3

[0023] figure 2 It is a schematic diagram of the cross-sectional structure of the bead part of the tubeless bias tire in this example. There are two bead wires 5 in the bead part of the carcass. There are 4 fetal toe coverings and 1 outside the mouth wrapping cloth 3, and there is a fetal toe covering cloth 3 outside the slit opening 1 and the fetal toe covering cloth 3. Sealing strip 2. The outer end of the fetal toe cloth 3 is aligned with the center of the innermost bead wire 5 in the carcass, and is closely attached to the outer surface of the sub-mouth cloth 1 and the fetal toe 4, and the other end is curved and extended to the inside of the carcass . The slit wrap 1 in this example is spandex monofilament cloth, the toe wrap 3 is canvas, and the width of the toe wrap 3 is 40mm.

Abstract

The invention relates to a tubeless oblique crossing tire, comprising tyre foundation which comprises a tyre bead section. Tyre bead wires are arranged in inner of the tyre bead section. Bead fabric is arranged on rebate of the tyre bead section. Bead toe fabric is arranged on bead toe of the rebate and the bead fabric. An outside end of the bead toe fabric centre justifies to the tyre bead wires which in the innermost of the tyre foundation, and clings to an outside end of the toes of the bead fabric, and another end goes around and clings in the tyre foundations to extend into inner side of the tyre foundations. A masking adhesive tape which can fully cover the bead fabric and the bead toe fabric is arranged outside of the bead fabric and the bead toe fabric. The bead fabric generally is singles cloth and the bead toe fabric is canvas materiel. According to different tyre specifications, the bead fabric can be singles cloth of nylon, urethane elastic fiber, chinlon and polypropylene fiber, and the width of the bead toe fabric also selects out a suitable size according to tyre specification. Because the bead toe fabric clings to the outside of the singles cloth, the invention handles out the singles cloth shrinkage strain and knotting problems in process of vulcanization, and also improves air tightness of the tyre.

Description

(1) Technical field: [0001] The invention relates to a tire, in particular to a tubeless bias tire. (two) background technology: [0002] In the existing tubeless bias tire, during the running of the vehicle, the rim of the bead part will rub against the steel ring, and the rim will be easily worn and slipped, which will cause the tire toe to leak oxygen and shift, reducing the air tightness of the tire . Although some tires are equipped with slit cloth on the bead part, most of them use monofilament cloth, and most of the monofilament cloth is made of nylon material. Nylon material is easy to shrink and knot after being heated during the vulcanization process, thus affecting the tire's durability. Quality and tire airtight performance. (3) Contents of the invention: [0003] The object of the present invention is to solve the problem that the toe wrap in the conventional technology is easy to shrink and knot when heated, and to provide a tubeless bias rubber tire with g...
