Description
Technical field
Tire manufacturing techniques field is the utility model is related to, is a kind of high rigidity with thickening casing ply specifically
Type tire.
Background technology
Tire is mainly by carcass, cushion（Belt）, tyre surface, sidewall composition, on wheel rim, by wheel rim branch
Hold, support vehicle body, buffer foreign impacts.Because tire is used under ground state, so the rigidity of tire is mainly relative
Rigidity in road surface.Feature is during tire used：Tire operating environment is harsh, and vehicle is exercised at high loads, and tire bears car
Common load with loading, the various power transmitted between vehicle and road surface are further increased, so as to cause squeegee action big, cut
Shear force becomes big heat and increased, and heat accumulation reaches after certain temperature that bonding strength reduces between rubber, and then causes tire shoulder, sidewall
The problems such as coming to nothing and being cracked.Come to nothing, being cracked has had a strong impact on the service life of tire, reduce the endurance quality of tire, pass through
Increase first layer cord thickness, improve tire sidewall and shoulder region rigidity, reduce deformation, improve product quality.
Utility model content
In order to solve the above-mentioned technical problem, the utility model discloses a kind of with the high rigidity type wheel for thickening casing ply
Tire, concrete technical scheme are as follows：
A kind of high rigidity type tire with thickening casing ply, including tyre surface, ply structure, sidewall and wire loop knot
Structure, wire loop structure are packaged in tire in glue, and glue is packaged in ply structure in tire, and ply structure is packaged in tread rubber
Interior, casing ply is arranged to interior casing ply and outer casing ply according to position, and the thickness of interior casing ply is more than the thickness of outer casing ply, interior
The number of plies of casing ply is one, and the number of plies of outer casing ply is more than or equal to one.
Further improvement of the utility model, interior casing ply bizet cord thickness are 1.2-3.6 times of cord line footpath.
Further improvement of the utility model, interior casing ply sidepiece cord thickness are 1.0-3.3 times of cord line footpath.
Further improvement of the utility model, sidewall position rigidity are 2-3 times of conventional tyre.
For the utility model according to pneumatic tire shear stress theoretical analysis result, distribution of shear stress situation is crown
It is larger by shear stress that other positions are compared near place, tire shoulder and around internal layer anti-package end points, wherein internal layer cord anti-package end
Dian Chu and wide buffering end points lower section shear stress values are maximum, optimize carcass ply combination according to tire material distribution map for this, right
The increase of carcass internal layer cord thickness, and rationally increase each site location thickness of internal layer carcass ply according to tyres of different types, it is interior
Layer bizet cord thickness is 1.2-3.6 times of cord line footpath, and sidepiece cord thickness is 1.0-3.3 times of cord line footpath, can be effective
Improve 2-3 times that each position rigidity of tire, especially sidewall position rigidity are conventional tyres, i.e. high rigidity type tire.According to resistance to
Long experiment characteristics, the stress of crown, especially tire shoulder, internal layer cord anti-package end points can be reduced simultaneously using the method, added
Strong lower sidewall rigidity, improves carcass strength, tire is turned into high rigidity type tire, the method is ensuring the base of overall performance of tire
On plinth, while the bonding force between casing ply and cord is enhanced, reduce the shearing force of casing ply, become during reduction tire used
The heat of shape, so solve the problems, such as tire come to nothing, cracking, improve tyres durable performance.
The beneficial effects of the utility model：Carcass deformation is big during conventional tire use, and the utility model passes through to wheel
Tire carcass internal layer cord rationally increases internal layer carcass ply crown, sidewall uniform thickness according to tyres of different types using cord is thickeied
Degree, effectively improves carcass rigidity, reduces shear stress suffered by each position；Compared with traditional detail design, the method can
Avoid due to deformed during the low use of tire stiffness it is big caused by come to nothing, the use quality problem such as be cracked, and then raising tire
Endurance quality.
