Abstract
The utility model relates to a novel load radial tire triangle is glued to be constructed, triangle including load radial tire tire bead position sets up along rim of the mouth to side wall position is glued, triangle glue comprises according to series arrangement three kinds of sizing materials, the connecting portion of three kinds of sizing materials all are provided with the slope of mutually supporting with adjacent sizing material shape angle, three kinds of sizing materials reduce according to the order hardness along rim of the mouth to side wall position in proper order. This technique is favorable to load meridian tubeless tire can be realized more in the same direction as smooth transition on the most weak side wall to intensity by intensity the highest rim of the mouth position, has reduced the possibility of using the indentation to cause early damage, the holistic life of extension tire.
Description
Technical field
The utility model relates to a kind of heavy load radial tubeless tires, particularly relates to the triangle rubber structure of heavy load radial tubeless tires.
Background technology
Generally, the triangle rubber of heavy load radial tubeless tires is all made up of a kind of flexible glue and a kind of ebonite.Supportive needed for heavy load radial tubeless tires both can be provided, also can be transitioned into more soft position, sidewall by flexible glue.The nonhomogeneous hardness of very important the is contact site of flexible glue and ebonite is very large, causes its strain gradient also can be very large, and then affect the service life of tire.
Summary of the invention
For overcoming the deficiencies in the prior art, in order to the problem that the flexible glue and ebonite contact site strain gradient that solve triangle rubber are excessive, cause the harmful effect to Using Life of Tyre.The utility model relates to a kind of heavy load radial tubeless tires Novel triangle plastic structure, comprise the triangle rubber that heavy load radial tire tyre bead portion is arranged along rim of the mouth to position, sidewall, described triangle rubber is rearranged in order by three kinds of sizing materials, the connecting portion of described three kinds of sizing materials is provided with the slope cooperatively interacted with adjacent sizing material shaped angles, and described three kinds of sizing materials reduce successively according to the order hardness along rim of the mouth to position, sidewall.
The described sizing material near position, sidewall is formed close to leg-of-mutton shape.
The sizing material being positioned at midway location in described sizing material is formed close to trapezoidal shape.
The sizing material being positioned at bead in described sizing material forms fitfull polygon, and itself and bead coil adjoin shape and the bead coil form fit at position.
Tyre triangular plastic structure adopts brand-new layout: the sizing material (flexible glue, middle glue and ebonite) that triangle rubber adopts three kinds of hardness different is composited, and according to hardness level (soft-in-hard) arrangement in turn, reduce the difference that sizing material hardness is excessive, avoid the phenomenon that strain gradient is excessive.This technology is conducive to heavy load radial tubeless tires can realize more smooth transition by the bead that intensity is the highest to the sidewall that intensity is the most weak, reduces the possibility using impression to cause earlier period damage, extends the service life of tire entirety.

Detailed description of the invention
The utility model is a kind of Novel triangle glue of heavy load radial tubeless tires, and its principal feature concentrates on the change of the structure of triangle rubber, by soft-in-hard three kinds of sizing materials form, and arrange in turn according to the size of hardness.This technology is conducive to the service life of improving heavy load radial tubeless tires.Principal feature is as follows: triangle rubber is rearranged in order by three kinds of sizing materials, the connecting portion of described three kinds of sizing materials is provided with the slope cooperatively interacted with adjacent sizing material shaped angles, and described three kinds of sizing materials reduce successively according to the order hardness along rim of the mouth to position, sidewall.The described sizing material near position, sidewall is formed close to leg-of-mutton shape.The sizing material being positioned at midway location in described sizing material is formed close to trapezoidal shape.The sizing material being positioned at bead in described sizing material forms fitfull polygon, and itself and bead coil adjoin shape and the bead coil form fit at position.
What 1, change triangle rubber consists of 3 kinds of sizing materials, and by three kinds of sizing materials according to hardness size arrange (according to the arrangement of hardness level in turn, successively by three kinds of sizing materials referred to as ebonite, middle glue and flexible glue), also just equal to have added a cambic horizon in the middle of original flexible glue and ebonite, reduce the hardness gradient of soft-ebonite contact position, and then reduce the strain gradient of contact site.
2, the part flexible glue of original triangle glue is replaced by middle glue, reduces the distortion at this position, and being unlikely to of simultaneously making the supportive of triangle rubber decline is too fast, plays transitional function.
3, same, the part ebonite of original triangle glue is also substituted by middle glue, reduces the hardness at this position, makes by bead more smooth and easy to the transition at position, sidewall.
4, the existence of middle glue makes triangle rubber integral structure more harmonious, tire can realize more smooth transition by the bead that intensity is the highest to the sidewall that intensity is the most weak, reduce the possibility using impression to cause earlier period damage, contribute to the service life extending tire entirety.
The Novel triangle glue of the heavy load radial tubeless tires of this technology is adopted to be that whole tire provides more rationally, smoothly by the transition of the highest bead of intensity to the most weak sidewall of intensity, and then reduce the strain gradient at triangle rubber position, reduce the possibility using impression to cause earlier period damage, contribute to the service life extending tire entirety.
