Abstract
The invention provides a tire belted layer structure which comprises at least two belted layers attached to a tire body in a surrounding mode. The first belted layer is located at the bottommost layer of all the belted layers and is a zero degree belted layer, that is to say, the cord thread of the first belted layer is parallel to the circumferential direction of a tire. The first belted layer is divided into a left part and a right part, and the left part and the right part are attached to the left side and the right side, deviating a certain distance away from the center of the tire, on the tire body respectively. Furthermore, the left part and the right part of the first belted layer are arranged bilaterally symmetric about the center of the tire. A joint of the first belted layer needs to be in lap joint after surrounding the tire body in a circle, the lap joint length ranges from 30 mm to 50 mm, and the joint is cut off at a 45-degree angle. Circumferential deformation in the tire running process can be greatly reduced, bearing capacity is enhanced, shearing force between the belted layers is reduced, and the service life of the tire can be prolonged.
Description
Technical field
The present invention relates to a kind of inside tires structure, especially a kind of tire belt Rotating fields of improvement.
Background technology
At present, the development of auto-industry and express highway, proposes higher performance requriements to motor tire, heavy load radial motor tire especially.At a high speed, carry, be also safely the problem of the tire development that client is day by day deeply concerned.More current countries thirst for the further pressure drop of cost according to economy development requirement and tire used person, are primary study directions of our tire enterprise.
Tire belt is the main stressed member of all-steel radial tyre, special performance requriements is had to its structure and steel cord, especially the inner tube free belt structure of four-layer structure, because this tire construction is on the basis of pursuing high speed, endurance quality, load-carrying capacity performance is not very outstanding.In addition in the use procedure of tire, there is phenomenon of coming to nothing sometimes, the phenomenon of namely throwing off between tire belt, thus the service life that have impact on tire.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of tire belt Rotating fields is provided, significantly can reduce the circumferential deformation in tire running process, load-carrying capacity is strengthened, shearing force minimizing (especially the focal point of stress of belt ends) that bracing ply is mutual, can extend Using Life of Tyre.The technical solution used in the present invention is:
A kind of tire belt Rotating fields, comprise at least two-layer bracing ply around being fitted on carcass, the first bracing ply is positioned at the bottom of all bracing plys, and the first bracing ply is zero-degree belt, and namely the cord of the first bracing ply is parallel to tire circumference; First bracing ply is divided into left and right two parts, is fitted in the left and right sides position of carcass departing from a tire centerline distance respectively.
Further, this tire belt Rotating fields, except the first bracing ply, also comprises the second bracing ply, the 3rd bracing ply, the 4th bracing ply; Second bracing ply is fitted in above the first bracing ply, and the width of the second bracing ply is greater than the first outermost two ends of bracing ply two parts; 3rd bracing ply is fitted in above the second bracing ply, and the width of the 3rd bracing ply is less than the second belt width; 4th bracing ply is fitted in above the 3rd bracing ply, and the width of the 4th bracing ply is less than the 3rd belt width.
Further, left and right two parts of the first bracing ply are symmetrical set relative to tire centerline.
Further, the first bracing ply needs overlap joint around the joint after carcass one circle, and the lap of splice is 30 ~ 50mm, and the joint mode of blocking is that miter angle blocks.
Tire belt Rotating fields of the present invention significantly can reduce the circumferential deformation in tire running process, and load-carrying capacity is strengthened, the shearing force minimizing that bracing ply is mutual, extends Using Life of Tyre.The design of this belt structure designs phase weight/power ratio with original belt structure and reduces, and cost reduces.

Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
The tire belt Rotating fields developed before applicant, as shown in Fig. 1, Fig. 2, is disposed with inside liner 7, carcass 6 from inside to outside, ground connection tyre surface 5 outside tire, is provided with belt structure between described carcass 6 and tyre surface 5 inside tire; Quadriply belt bundle Rotating fields be arranged on tyre surface 5 times, on carcass 6; First bracing ply 1 is fitted on carcass 6, and the second bracing ply 2 is fitted in above the first bracing ply 1, and the 3rd bracing ply 3 is fitted in above the second bracing ply 2, and the 4th bracing ply 4 is fitted in above the 3rd bracing ply 3.When side, tire left and right is subject to the adverse factors such as shearing force, often involves opposite side, therefore may cause phenomenon of coming to nothing.
Tire belt Rotating fields provided by the invention, as shown in Figure 3, Figure 4, comprises the first bracing ply 1, second bracing ply 2, the 3rd bracing ply 3, the 4th bracing ply 4; First bracing ply 1, second bracing ply 2, the 3rd bracing ply 3, all built-in steel cord of the 4th bracing ply 4, the steel cord of the second bracing ply 2, the 3rd bracing ply 3, the 4th bracing ply 4, all according to certain angle severing, arranges a circle (arranging with tire is concentric) around tire afterwards successively.
First bracing ply 1 is zero-degree belt, and namely the steel cord of the first bracing ply 1 is parallel to tire circumference; First bracing ply 1 is divided into left and right two parts, is fitted in the left and right sides position of carcass 6 departing from a tire centerline distance respectively; Second bracing ply 2 is fitted in above the first bracing ply 1, and the width of the second bracing ply 2 is greater than the first outermost two ends of bracing ply 1 two parts; 3rd bracing ply 3 is fitted in above the second bracing ply 2, and the width of the 3rd bracing ply 3 is less than the second bracing ply 2 width; 4th bracing ply 4 is fitted in above the 3rd bracing ply 3, and the width of the 4th bracing ply 4 is less than the 3rd bracing ply 3 width.
As shown in Figure 5, the first bracing ply 1 needs overlap joint around the joint after carcass 6 one circle, and the lap of splice is 30 ~ 50mm, and the joint mode of blocking is that miter angle blocks.
Said structure improves can bring following benefit:
1) in the present invention, the first bracing ply adopts zero-degree belt, significantly can reduce the circumferential deformation in tire running process, and load-carrying capacity is strengthened.
2) the first bracing ply is divided into the left and right two parts of being separated by, and shearing force mutual between bracing ply can be reduced, and especially between the first zero-degree belt end points and the second bracing ply, the stress that can reduce by more than 20% through this design of test proof is concentrated.Reduce the phenomenon of coming to nothing that tire shoulder position is caused owing to being subject to adverse factor, actv. prevents the earlier period damage of tire.
3) zero-degree belt is divided into two parts, and centre is rubber, can reduce the consumption of steel cord in full-steel radial ply, realize tire lightweight, reduce costs.
