Abstract
The present invention relates to a kind of tire crown structure, specifically a kind of all-steel radial tyre crown structure belongs to tire construction technical field.It includes the liner layer, carcass and tyre surface set gradually from inside to outside, the belt structure includes the first belt set gradually from Inside To Outside, the second belt, third belt and the 4th belt, and the both ends of the first belt extend at sidewall location along carcass outer surface and sidewall glue-line inner surface；Shoulder wedge is equipped at left and right sides of the belt structure, shoulder wedge is connect with tyre surface inner surface, the second belt inner surface and the first belt outer surface respectively.The present invention reinforces sidewall position by the sidewall that extends to of the first belt, so that the deformation of sidewall position is reduced, improves sidewall rigidity, improves tire capacity；Even if sidewall deformation position is still easy the contact hard object in ground under the protection of the first belt, pierced risk can also be substantially reduced, improves tire safe capability.
Description
Technical field
The present invention relates to a kind of tire crown structure, specifically a kind of all-steel radial tyre crown structure belongs to
Tire construction technical field.
Background technique
With the needs of urban development, what all-steel radial tyre was more and more extensively sent out is employed for each carrier, no
Pipe is mining area, high speed or is small towns transhipment, is found everywhere the shadow of all-steel radial tyre.With the continuous popularization of application,
More stringent requirements are proposed for the performance to all-steel radial tyre of people gradually, these different demands promote all-steel meridian
Line wheel tire towards load-carrying change, speed faster, the higher direction of traveling longer life expectancy, security performance continues to develop.Certainly in property
Also some difficult and bottlenecks are encountered in the progradation that can be promoted, for example, to the promotion of wheel crown part load-carrying properties, severe
The promotion of sidewall intensity is not very significantly improved under road conditions, is badly in need of technical staff and improves.
In the prior art, all-steel radial tyre is more with quadriply belt beam layer structure, and development slowly is that 0 ° of belt adds
Triple layer belt beam layer bearing type tire crown structure is in the majority.In the prior art, all-steel radial tyre is in tire case of heavy load lower sidewall
Deformation is larger to be easy to damage under severe road conditions, influences the service life of all-steel radial tyre.
Summary of the invention
It is an object of the present invention to overcome the above deficiencies, so that a kind of all-steel radial tyre crown structure is provided,
First belt both ends are extended into tire sidewall position, strengthen sidewall portion structure intensity, so that the deformation of sidewall position subtracts
It is few, sidewall rigidity is improved, tire capacity is improved.
According to technical solution provided by the invention, all-steel radial tyre crown structure includes setting gradually from inside to outside
Liner layer, carcass and tyre surface, center position is equipped with belt structure, described carcass outer surface or so between carcass and tyre surface
Two connection sidewall glue-lines, sidewall glue-line extend up to carcass outer surface, it is characterized in that: the belt structure include from
The first belt, the second belt, third belt and the 4th belt that Inside To Outside is set gradually, the first belt
Both ends extend at sidewall location along carcass outer surface and sidewall glue-line inner surface；It is equipped at left and right sides of the belt structure
Shoulder wedge, shoulder wedge connect with tyre surface inner surface, the second belt inner surface and the first belt outer surface respectively
It connects.
Further, the 4th belt includes at least two 0 ° of belts, at least two 0 ° of belt connections stacked on top of one another
Integrally.
Further, tyre surface includes the tread base glue-line set gradually from inside to outside and tyre surface hat glue-line, tread base
Glue-line medial surface connects belt structure, and tread base glue-line lateral surface connects tyre surface and is preced with glue-line.
Further, the width dimensions of the first belt are 150 ~ 200mm bigger than the width dimensions of the second belt.
Compared with the prior art the present invention has the advantage that
The invention has the advantages of simple structure, compactness and reasonable structure, by the sidewall that extends to of the first belt, reinforces sidewall position, so that sidewall
Position deformation is reduced, and is improved sidewall rigidity, is improved tire capacity；Sidewall deformation position is under the protection of the first belt
Just or it is easy the contact hard object in ground, pierced risk can also be substantially reduced, improve tire safe capability；Due to first band
The increase of beam slice width degree, crown integrated carrying ability effectively improve, especially shoulder region, and 0 ° of belt can be assisted to improve wheel
The banding coefficient of crown part, to improve the bearing capacity of tire.
Detailed description of the invention
Fig. 1 is main view of the present invention.
Description of symbols: 1- liner layer, 2- carcass, 3- tyre surface hat glue-line, 4- tread base glue-line, the sidewall 5- glue-line,
The first belt of 6-, the second belt of 7-, 8- third belt, the 4th belt of 9-, 10- shoulder wedge.
Specific embodiment
The present invention will be further described in conjunction with the embodiment in attached drawing below:
As shown in Figure 1, the invention mainly comprises the liner layer 1 set gradually from inside to outside, carcass 2 and tyre surface, carcass 2 and tyre surface
Between center position be equipped with belt structure.
The tyre surface 3 includes the tread base glue-line 4 set gradually from inside to outside and tyre surface hat glue-line 3, tread slab base
4 medial surface of layer connect belt structure, and 4 lateral surface of tread base glue-line connects tyre surface and is preced with glue-line 3.
Two connection sidewall glue-lines 5 of described 2 outer surface of carcass or so, sidewall glue-line 5 extends up to 2 outside table of carcass
Face.
The belt structure includes the first belt 6 set gradually from Inside To Outside, the second belt 7, third
The width dimensions of belt 8 and the 4th belt 9, the first belt 6 are 150 ~ 200mm bigger than the width dimensions of the second belt 7,
The both ends of first belt 6 extend at sidewall location along 2 outer surface of carcass and 5 inner surface of sidewall glue-line.
4th belt 9 includes at least two 0 ° of belts, and at least two 0 ° of belts are stacked on top of one another to connect into one
Body.
Be equipped with shoulder wedge 10 at left and right sides of the belt structure, shoulder wedge 10 respectively with tyre surface inner surface, the
Two belts, 7 inner surface and the connection of 6 outer surface of the first belt.
The invention has the advantages of simple structure, compactness and reasonable structure, by the sidewall that extends to of the first belt, reinforces sidewall position, so that
The deformation of sidewall position is reduced, and is improved sidewall rigidity, is improved tire capacity；Sidewall deformation position is under the protection of 1# belt
Even if being still easy the contact hard object in ground, pierced risk can also be substantially reduced, improves tire safe capability；Due to first
The increase of belt width, crown integrated carrying ability effectively improve, especially shoulder region, and 0 ° of belt can be assisted to improve
The banding coefficient for taking turns crown part, to improve the bearing capacity of tire.
