Further, the width of described the first belt is less than the width of described the second belt; The width of described the second belt is greater than the width of described the 3rd belt; The width of described the first belt is less than the width of described the 3rd belt; The width of described the 4th belt is less than the width of described the first belt.
Further, the ratio between distance and the width of described the 3rd belt between two outer ledges of described two limit portion belt structures is 0.9 to 1.2.
Further, the distance between two inside edges of described two limit portion belt structures is less than the width of described the 3rd belt.
Further, the distance between two outer ledges of described two limit portion belt structures is greater than the width of described the 3rd belt.
Further, each described limit portion's belt structure and described four-tape bundle interlayer are every setting.
Further, the width of each described limit portion belt be described the 3rd belt width 1/12 to 1/9.
On the other hand, the utility model also provides a kind of heavy load radial tire, and it comprises carcass and tyre surface, and above-mentioned any tire belt structure, and tire belt structure is arranged between described carcass and described tyre surface.
In tire belt structure and heavy load radial tire that the utility model provides, because the both sides of the 4th belt have limit portion belt, effectively reduce belt interlayer shear, greatly promoted tire shoulder endurance quality, thereby can greatly extend the service life of tire.
Brief description of the drawings
Hereinafter describe specific embodiments more of the present utility model in detail in exemplary and nonrestrictive mode with reference to the accompanying drawings. In accompanying drawing, identical Reference numeral has indicated same or similar parts or part. It should be appreciated by those skilled in the art that these accompanying drawings may not draw in proportion. In accompanying drawing:
Fig. 1 is according to the schematic diagram of the tire belt structure of an embodiment of the utility model;
Fig. 2 is according to the schematic diagram of the tire belt structure of another embodiment of the utility model;
Fig. 3 is according to the schematic diagram of the heavy load radial tire of an embodiment of the utility model.
Detailed description of the invention
According to the detailed description to the utility model specific embodiment by reference to the accompanying drawings below, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Fig. 1 is according to the schematic diagram of the tire belt structure of an embodiment of the utility model. As shown in Figure 1, the utility model embodiment provides a kind of tire belt structure 100 for tire. Tire belt structure 100 can comprise along the radial direction of tire successively outwards the first belt 10, the second belt 20, the 3rd belt 30 and the 4th belt 40 that arrange and that can have certain angle and direction. Especially, in the tire belt structure 100 of the utility model embodiment, only the both sides of the 4th belt 40 are provided with limit portion belt structure 50, and each limit portion belt structure 50 comprises at least one deck limit portion belt 51. For example, as depicted in figs. 1 and 2, the limit portion belt 51 of each limit portion belt structure 50 is two-layer or one deck. Limit portion belt structure 50 is only set in the both sides of the 4th belt 40 and can significantly reduces belt interlayer shear, and can make the simple in structure of tire, easily manufactured, cost is low.
Preferably, in embodiment more of the present utility model, each limit portion belt 51 is zero-degree belt.
In embodiment more of the present utility model, the width of the first belt 10 is less than the width of the second belt 20; The width of the second belt 20 is greater than the width of the 3rd belt 30; The width of the first belt 10 is less than the width of the 3rd belt 30; The width of the first belt 10 is greater than the width of the 4th belt 40. For example, the width ratio of the first belt 10 and the second belt 20 is 0.8 to 0.95; The width ratio of the 3rd belt 30 and the second belt 20 is 0.85 to 0.97; The width ratio of the 4th belt 40 and the first belt 10 is 0.6 to 0.85.
Further, the distance between two inside edges of two limit portion belt structures 50 is less than the width of the 3rd belt 30. Ratio between distance and the width of the 3rd belt 30 between two outer ledges of two limit portion belt structures 50 is 0.9 to 1.2. The width of each limit portion belt 51 be the 3rd belt 30 width 1/12 to 1/9. Preferably, each limit portion belt structure 50 and the 4th belt 40 intervals arrange.
