[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] In one embodiment, Figure 1-Figure 3 As shown, a novel lightweight tire bead structure for a light truck includes an outer tire body 100 and an inner tire body 101, wherein the outer tire body 100 is provided with a sidewall 201, a wear-resistant rubber 202, an outer tire body 203, an inner liner 204, and an inner tire body 205 in sequence from the outside to the inside, and also includes a filling component and a steel wire component, wherein a filling component for filling is provided between the outer tire body 203 and the inner tire body 205, and a steel wire component for enhancing the tire body hardness is provided at the lower part of the inner tire body 205.

[0025] In one embodiment, Figure 1-Figure 2 As shown, the filling component includes a lower apex rubber 206 and an upper apex rubber 207. The upper apex rubber 207 is arranged between the outer carcass 203 and the inner carcass 205. The upper apex rubber 207 is wrapped by the sidewall 201, the wear-resistant rubber 202 and the turned-up part of the outer carcass 203 from the inside to the outside. The lower apex rubber 206 is arranged between the upper apex rubber 207 and the inner carcass 205. The lower apex rubber 206 and the upper apex rubber 207 are used to fill the space between the outer carcass 203 and the inner carcass 205, and at the same time support and fix the steel wire.

[0026] In one embodiment, Figure 1-Figure 2 As shown, the lower triangle rubber 206 is made of rubber with high modulus and strong resistance to permanent deformation, which prolongs the service life of the structure.

The lower center area of ​​the lower apex rubber 206, the inner liner 204, and the outer carcass 203 is provided with a main steel wire ring 208. The outer carcass 203, the inner carcass 205, and the upper apex rubber 207 are wrapped with a carcass steel wire. The hardness of the main steel wire ring 208 is greater than that of the lower apex rubber 206, and the hardness of the lower apex rubber 206 is greater than that of the upper apex rubber 207. The angle of the tire is 90 degrees and symmetrically distributed. The main wire ring 208 is wound around the tire. The end point size of the outer carcass 203 is 30mm-35mm. The hardness of the wear-resistant rubber 202 is between 70 and 80 Shore hardness. By not using wire cloth, the disadvantages of high density and heavy weight of the steel wire material are reduced, forming a special carcass and bead winding method. The new wire cloth-free design is adopted to effectively reduce the weight of the tire and achieve lightweight tire. With the cooperation of high-hardness wear-resistant rubber 202 and high-hardness triangle rubber 206, the strength of the steel ring can be maintained.

[0028] In one embodiment, Figure 1-Figure 3 As shown, the upper apex rubber 207 has a strong adhesive force with the inner carcass 205, and the height of the upper apex rubber 207 is greater than the height of the outer carcass 203, with a difference of 15mm-25mm, ensuring good anti-destruction performance during driving.

[0029] Working principle: When in use, the lower triangle rubber 206 and the upper triangle rubber 207 are used to fill the space between the outer carcass 203 and the inner carcass 205, and at the same time the steel wire is supported and fixed. By not using steel wire cloth, the disadvantages of high density and heavy weight of the steel wire material are reduced, forming a special carcass and tire bead winding method. The new design without steel wire cloth is adopted to effectively reduce the weight of the tire and achieve lightweight tire. With the cooperation of high hardness wear-resistant rubber 202 and high hardness lower triangle rubber 206, the strength of the steel rim can be maintained.
