Description
Technical field
The utility model belongs to all steel tubeless meridian tire production technical field, and in particular to a kind of high-load performance
All steel tubeless meridian tire.
Background technology
Radial tubeless ratio more and more higher, existing all steel tubeless meridian tire is most only suitable
Used down again for gauge load or underloading, but domestic short-distance sand material and other items transport overload condition is serious, it is necessary to higher
The full-steel radial ply tubeless tyre of load performance.
Using a section to be formed for the circular glue steel wire winding that covers tubeless tyre wire loop more；Tyre contour outline curve
Circle portion is from wheel rim contact site using two sections of different angle designs；Tire calls in person position using the design of anti-arc.
Improve load performance, there is enhanced using U-shaped enhancement layer cord, have using one layer of U-shaped enhancement layer cord outer patch or
What two layers of fiber infantees was strengthened, have what is strengthened using I type enhancement layers cord.Split for tire heel without new scheme, wire loop is more
Formed using section circle steel wire winding.
1st kind of reinforcement, as shown in figure 1, applying one layer of enhancement layer cord in carcass ply outer layer, encases circle portion carcass
Cord, forms U-shaped, and enhancement layer can buffer the stress between wheel rim and carcass ply, and add strong circle portion, improve circle portion rigidity,
Deformation is reduced, carcass ply is protected, this structure is applied to gauge load situation.High capacity hour circle portion is because of enhancement layer protective effect
Deformation point is caused to move up, carcass ply endpoint location is higher than enhancement layer, the deformation of cord end points increases, and cord end points is in tire running
During repeated deformation produce fine cracks, crackle gradually increases, and forms carcass and enhancement layer or disengages to form circle with glue component
Sky, crackle increase may also lead to glue component and be split in endpoint location tear type lopping, produce earlier period damage.
2nd kind of reinforcement, as shown in Fig. 2 strengthened using one layer of U-shaped enhancement layer cord outer patch or two layers of fiber infantees,
Fiber infantees protects the end points part of carcass ply and steel wire infantees, improves circle portion rigidity, can reduce under load condition two
The deformation of end points, this structure is applied to light load condition.Fibercord is relatively soft, and self-deformation is larger during high capacity, to two
The protection of individual end points can be reduced.
3rd kind of reinforcement, as shown in figure 3, strengthened using I type enhancement layers cord, enhancement layer the outer end point is higher than or low
In carcass ply end points, and only the local carcass ply in circle portion is protected, tyre bead integral rigidity is not big enough, and this structure is applicable
In gauge load situation.
Existing wire loop manufacture craft, as shown in figure 4, existing wire loop uses a section to be twined for the circular glue steel wire that covers
Around into profile is hexagonal, is point contact between steel wire, stress concentration, and configuration is unstable between steel wire, steel under loading condition
The rubber stress in silk table face can deform, and reduce the bulk strength of wire loop；Wire loop semi-finished product are in tire manufacturing process
Because stress can deform, irregular hexagon is formed；Every steel wire of wire loop bottom is with wheel rim a little to be contacted, contact
Pressure is uneven, and deformation is big；Wire loop after winding is directly combined with filling glue is made clad steel wire ring, and clad steel wire ring is used again
In shaping, steel wire covers elasticity of the sizing material with very big mobility and very little, and wire loop holds in subsequent tyre manufacturing process
It is yielding.
As shown in Figure 5 and Figure 6, the circle portion of existing tyre contour outline curve is set from wheel rim contact site using two sections of different angles
Meter, tyre bead and wheel rim contact are uneven；The upper position of tire heel is using the anti-arc designs of 12-, and the upper position sizing material of tire heel is thin, negative in height
In the case of load, sizing material deformation is big, low intensity, repeatedly stress deformation product fatigue break, forms tire heel and splits.
Existing carcass anti-package is all low anti-package, and anti-extraction ability is relatively low, is not suitable for high capacity.In addition, existing all steel
The tubeless meridian tire overwhelming majority is only applicable to gauge load or underloading and used down again, and when loading high, deformation increase, raw
Heat increases, and sizing material is in the case of high temperature and repeated deformation, and earlier period damage, especially circle portion occur for hydraulic performance decline, occurs circle sky, circle
Split, reel off raw silk from cocoons it is quick-fried.Circle is empty to be occurred between carcass ply and enhancement layer cord, between carcass ply and glue component, enhancement layer and glue
Between part；Circle, which splits, betides carcass ply end points, enhancement layer end points, tyre heel arc position；Circle is empty, circle splits continuation development to cause
Carcass ply reels off raw silk from cocoons and blown out, that is, reels off raw silk from cocoons quick-fried.
Utility model content
Causing circle portion to occur for tyre load poor-performing present in prior art, circle is empty, circle splits, quick-fried skill of reeling off raw silk from cocoons
Art problem, the purpose of this utility model is all steel tubeless meridian tire for providing a kind of high-load performance, applied to negative
The higher tire of performance is carried, that is, strengthens the ability that tire is capable of bearing load normally travel, using brand-new structure and manufacture work
