Embodiment Construction
[0011] The section structure of the existing all-steel wire radial truck tire with inner tube is as follows: figure 1 As shown, a 0° belt layer 2 and a small-angle belt layer 3 are provided between the carcass 5 and the tread 1, and a wear-resistant rubber strip 10 is provided on the inner side of the sidewall 4 at the rim, and the carcass 5 is located in the bead 8 Fill the top filler 6 and the bottom filler 7 between the upper part and the sidewall 4, and the outside of the carcass 5 at the slit is provided with a steel wire slit cloth 10.
[0012] The carcass 5 adopts an original layer of steel cords with a structure of 3+9+15×0.22.
[0013] The cross-sectional structure of the reinforced load-bearing all-steel wire radial tire of the present invention is as follows: figure 2 As shown, the outside of the carcass 5 at the slit is provided with a steel wire slit wrapping cloth 11 and a steel wire slit wrapping cloth 12 for pressing the carcass 5 turn-up end point, and a ste...

The invention discloses an enhanced truck all steel wire radial tire. Double-layer tire bead fabric used for pressing an anti-package end point of a tire body is arranged at the outer part of the tire body in a tire bead position, and steel wire tire bead fabric is packaged on the tire body in the tire bead position in a U-shaped structure way, so that the strength of the tire bead can be enhanced, and problems of the tire bead are eradicated. The tire bead adopts a U-shaped packing mode to press the anti-package end point of the tire body, and adopts a 15-degree angle, simultaneously the tire bead steel wire is flexible, and the enhanced truck all steel wire radial tire is not like a tire which has the disadvantages that the tire body is 90 degrees, end points are in parallel, the rigidity is high, the transition is not smooth, and hard steel wire is immediately transited to soft rubber. The enhanced truck all steel wire radial tire has the improvement of transiting from hardness to softness gradually, ensures that tire bead crake and tire bead wire drawing are greatly improved, prolongs the service life of the tire, and saves resources.
Description
technical field [0001] The invention relates to the technical field of tires, in particular to a load-bearing all-steel wire radial tire. Background technique [0002] my country began to study all-steel radial tires in the 1960s and tried to produce all-steel radial tires. However, until the 1980s, the technical level of producing high-quality all-steel radial tires had not yet been formed, and the quality and output were far inferior to those of the United States and China. In Japan, until the 1980s to the early 1990s, my country's tire companies began to introduce the production technology and equipment of all-steel radial tires from abroad. The level and output have also been developed rapidly, and new products have been introduced continuously. However, due to the long time of introducing technology at that time, it has been used for many years, and it has fallen far behind the existing demand. According to the continuous improvement of national road conditions, the ...
