Abstract
The utility model belongs to the technical field of tire structural design, and particularly relates to an all-steel light load radial tire in a double belt ply structure. The all-steel light load radial tire comprises a tread, belt plies, sidewall rubber, an inside liner, a tire body cord fabric, bead filler, steel wire wrapping cloth, wear-resisting rubber and a bead ring. The belt plies are formed by a first belt ply and a second belt ply, the width of the first belt ply is larger than that of the second belt ply, the first belt ply and the second belt ply are both in cross-over design in small angles ranging from 15 degrees to 24 degrees, and all-steel cords of the first belt ply and all-steel cords of the second belt ply are all high-strength all-steel cords. According to the all-steel light load radial tire in the double belt ply structure, strength of the belt plies of the tire is guaranteed, the thickness and the weight of the tire are appropriately reduced, themogenesis in tire using is reduced, tire cost is reduced, and cost performance of the tire is improved.
Description
Technical field
The utility model belongs to the Design of Tire Structure technical field, relates in particular to a kind of all-steel light radial truck tire of two-layer belt structure.
Background technology
The all-steel light radial truck tire of existing belt structure comprises crown, bracing ply, carcass ply, inside liner, bead coil, steel wire infantees, sidewall rubber and wear-resisting glue, and bracing ply is made of the first bracing ply, the second bracing ply and the 3rd bracing ply.Ground floor is cambic horizon near carcass, generally adopts the design of 50 ° of-60 ° of wide-angles, and the second layer and the 3rd layer adopt the design of 15 ° of-24 ° of low-angles for the main stress layer of band bundle.Ground floor adopts relatively a little bit smaller high tensile steel wire of wire diameter, second, third layer employing intensity, the HT(high strength that rigidity is higher) steel cord.Existing structure tire cost is high, and cost performance does not have advantage, and tire does not have competitive power.
Summary of the invention
In order to solve above-mentioned technological deficiency, the purpose of this utility model provides a kind of all-steel light radial truck tire of two-layer belt structure, this tire had both guaranteed the bracing ply intensity of tire, thickness and the weight of tire have suitably been reduced again, reduce the heat of giving birth in the tire used, reduce the tire cost, improve the cost performance of tire.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
The all-steel light radial truck tire of two-layer belt structure, this all-steel light radial truck tire comprise crown, bracing ply, sidewall rubber, inside liner, carcass ply, triangle rubber, steel wire infantees, wear-resisting glue and bead coil; Described bracing ply is made of the first bracing ply and the second bracing ply, the width of the first bracing ply is greater than the second bracing ply, the first bracing ply and the second bracing ply all adopt 15 ° ~ 24 ° low-angle cross-over design, and the steel cord of the first bracing ply and the second bracing ply all adopts high tenacity steel cord.
As preferably, the first above-mentioned bracing ply and the second bracing ply all adopt 18 ° of low-angle cross-over design.
The utility model is owing to having adopted above-mentioned technical scheme, and ground floor bracing ply, second layer bracing ply are main stress layer, all adopt 15 ° ~ 24 ° low-angle cross-over design.Ground floor adopts 15 ° ~ 24 ° low-angle designs, and the wide-angle design load-carrying capacity than 50 °-60 ° is stronger.The second layer adopts 15 ° ~ 24 ° low-angle cross-over design, increases the rigid circumference of tire, thereby improves the service life of tire.The utility model belt structure had both guaranteed the bracing ply intensity of tire, had suitably reduced again thickness and the weight of tire, reduced the heat of giving birth in the tire used, reduced the tire cost, improved the cost performance of tire.

Fig. 2 is the structural representation of ground floor bracing ply.
Fig. 3 is the structural representation of second layer bracing ply.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
The all-steel light radial truck tire of two-layer belt structure as shown in Figure 1, this all-steel light radial truck tire comprise crown 1, bracing ply, sidewall rubber 4, inside liner 5, carcass ply 6, triangle rubber 7, steel wire infantees 8, wear-resisting glue 9 and bead coil 10; Described bracing ply is made of the first bracing ply 3 and the second bracing ply 2, and the width of the first bracing ply 3 is greater than the second bracing ply 2.Such as Fig. 2, shown in Figure 3, the first bracing ply 3 and the second bracing ply 2 all adopt 15 ° ~ 24 ° low-angle cross-over design, and the steel cord of the first bracing ply 3 and the second bracing ply 2 all adopts high tenacity steel cord.
Since in January, 2010, adopt the all-steel light load-carrying tubeless meridian tire of two-layer belt structure, tyres durable performance, high speed performance all meet and exceed national standard, USSt DOT119 and European standard ETRTO, leading domestic, international advanced level that the tire Combination property has reached.After the all-steel light load-carrying tubeless meridian tire of two-layer belt structure is put on market, the Win Clients favorable comment bad feedback do not appear.
