Description
Technical field
The utility model is related to the utility model is related to arrive a kind of resistance to Pneumatic belt tire.
Background technology
All the time, as the belt of Pneumatic belt tire, zero-degree belt structure is that card car is common in the market
Tire belt structure.
The tire of existing zero-degree belt structure, shoulder are effectively controlled tire under zero-degree belt effect
The expansion of shoulder reduces the generation of shoulder friction phenomenon.Very important is that there are in bizet for conventional zero degree belt structure
Between expand and increase, after tire running, ground connection contour shape is deteriorated, and wear hardness is deteriorated；And the displacement of belt is caused to change
It is larger, belt endurance quality is influenced, and then influence the service life of tire.
All the time, zero-degree belt structure and 4 layers of belt structure are the common tire belts of card car in the market
Structure.But easily there is the problem of blowing out under hyperbar, high load capacity effect in the Pneumatic belt tire of 4 layers of belt structure.
However, the Pneumatic belt tire of zero-degree belt structure is then seldom blown out.Therefore, zero-degree belt structure right and wrong are selected
Often it is necessary to.
And the Pneumatic belt tire of existing zero-degree belt structure, although shoulder under zero-degree belt effect, has
The expansion for controlling tyre shoulders of effect, reduces the generation of shoulder friction phenomenon and phenomenon of blowing out.But very important is existing
Big with the presence of zero-degree belt structure bizet intermediate expansions, after tire running, ground connection contour shape is deteriorated, and wear hardness is caused to become
Difference；And the displacement of belt is caused to change greatly, belt endurance quality is influenced, and then influence the service life of tire.
Show that the radial of existing zero-degree belt structure, bizet and shoulder connect by a large amount of experimental study
The long difference in ground is larger, and the variation for docking ground contour also has an impact.After causing traveling, the central portion of existing zero-degree belt connects
Ground length shoulder to shoulder minister, be easy to happen intermediate easily mill；The displacement that existing zero-degree belt generates changes greatly, and is also easy to produce belt
The stress concentration of endpoint.Cause tire wear performance to decline, influences the endurance quality of product.Therefore, it is necessary to existing zero degree
Belt structure, which carries out improvement, to be necessary.
Invention content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of Pneumatic belt tire, passes through
The zero-degree belt structure of the utility model solves wear hardness decline after being exercised caused by ground connection profile variations influence and asks
Topic, and solve the problems, such as that endurance quality caused by belt displacement deformation amount is big declines, effectively raise tire used performance.
In order to achieve the above purpose, the utility model uses technical solution below：
A kind of Pneumatic belt tire, the tire include body piles, tread ply and belt, and the belt includes extremely
Rare two layers or more the tension belt intersected, two end regions of tension belt, which are covered each by, to be provided with two layers
One zero-degree belt, tension belt covers in the middle part of bizet is provided with two groups one layer or more of the second zero-degree belt.
Preferably, second zero-degree belt is one layer, the 10% of crown center is arranged in the second zero-degree belt
60% region at region to crown center, the width of every group of second zero-degree belt should be greater than or equal to the first zero-degree belts
Width.
According to the utility model, by above structure, the bizet intermediate expansions that solve existing zero-degree belt structure are big,
The problems such as belt displacement is changed greatly, causes the undesirable influence of Life of Tyre.It is effectively controlled tire ground connection profile
Deformation and the variation of belt displacement, that is, wear hardness declines after solving the problems, such as traveling, and realizes and improve endurance quality
Heavy duty pneumatic radial tire.

Specific implementation mode
Specific embodiment of the present utility model is made a detailed explanation below in conjunction with the accompanying drawings.
In Fig. 1, amplification indicates the sectional view near the fetus face of the Pneumatic belt tire of the utility model.Diagram
It is skeleton that the Pneumatic belt tire 1 of the utility model, which is with body piles 2, outside the tire radius direction of the body piles 2
Side stacked above one another setting belt 6 and tread ply 7 form.
In the present invention, belt 6 includes that at least 2 layers or more the tension belts 3 intersected form, belt
6 are located at body piles 2 on skeleton；Second zero-degree belt 4 is located at 6 end position of belt (consistent with existing 0 degree of structure).
Also, second degree of belt 5 is that have two groups, and at least one layer or more 0 degree of belt composition, and position is in intersection
Between tension belt 6 and tread rubber 7, between 10% region 8 and 60% region 9 at crown center 10, second degree of belt
5 width should be greater than or be equal to 4 width of the second zero-degree belt.
Tire ground connection profile deformation and belt displacement are effectively controlled by above structure according to the utility model
Amount variation, that is, wear hardness declines after solving the problems, such as traveling, and realizes the heavy duty pneumatic radial wheel for improving endurance quality
Tire.
It is illustrated in fig. 2 shown below, is the traveling of the utility model zero-degree belt structure and existing zero-degree belt structure respectively
Tyre surface after preceding and traveling is grounded mark figure, and test specification is the Pneumatic belt tire of 12.00R20.
In the Pneumatic belt tire of experiment, the tyre surface of tire is grounded mark figure intermediate expansions, the utility model structure
It is substantially better than the Pneumatic belt tire of existing zero-degree belt structure, especially after traveling, the nullity belt of the utility model
The tyre surface ground connection mark figure intermediate expansions of beam layer structure are obviously reduced.Confirm the zero-degree belt structure using the utility model
Pneumatic belt tire can improve wear hardness of the product after enforcement.
Shown in Fig. 3, Pneumatic belt tire overall diameter is upheld before and after distribution (tread cap center and shoulder) and traveling
Difference schematic diagram.The utility model belt all shows impartial stretch variation before and after traveling；Though and zero-degree belt
Equivalent change is so shown under aeration, but is only had after travelling and upheld among bizet.
Shown in Fig. 4,5,6, Pneumatic belt tire overall diameter upholds distribution (tread cap center and shoulder) and row
Sail the changing value of front and back overall diameter.Confirm that the Pneumatic belt tire using the zero-degree belt structure of the utility model can
Improve belt displacement changing value of the product after enforcement to reduce, the endurance quality of product can be effectively improved.
It is as shown in table 1 according to company standard, indoor endurance quality experimental test, the utility model are carried out to both structures
The indoor endurance quality testing level height of zero-degree belt structure have the 10% of zero-degree belt structure；
1 B3 all steels of table have inner tube of a tyre endurance test
