According to the bead structure, the supporting performance of a bead position can be improved, the flexible rigidity of the bead position under a high load condition can be improved, the stress dispersive capacity of an endpoint position can be improved, and the damage caused by stress concentration in the endpoint position to a tire can be reduced.
Description
Technical field
The utility model relates to motor tire field, particularly a kind of all-steel radial tyre toe mouth structure.
Background technology
At present, automobile all-steel radial tyre comprises the hard triangular rubber core of inner side, soft triangular rubber core, carcass ply, toe chewing-gum, sidewall rubber and the toe mouth filling glue in outside, wherein said hard triangular rubber core and soft triangular rubber core are filled glue by carcass ply, inside liner and toe mouth successively from inside to outside and are wrapped up, the lower end of whole tire toe structure is encased by toe chewing-gum, this toe chewing-gum is wrapped to form " U " shape, and described toe chewing-gum outer upper end end is surrounded by sidewall rubber.Traditional design mode is under mark carrier strip part, the rich performance of toe mouth support performance and resistance to song can meet Vehicle Driving Cycle requirement, but not fine for road conditions, bend is larger, road conditions management is not the environment for use of standard very, the usage conditions such as overload, air pressure is higher, above toe mouth design ubiquity support performance deficiency, the rich ability of resistance to song decline, stress is easily concentrated etc. causes tire toe sky, the quality problems such as quick-fried.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of resistance to song have mercy on ability, the better all-steel radial tyre toe of supporting capacity mouth structure.
The technical solution of the utility model is as follows:
A kind of all-steel radial tyre toe mouth structure, comprise inside liner (1), carcass ply (2), toe mouth is strengthened wirecord fabric (3), the hard triangular rubber core (4) of inner side, toe chewing-gum (5), sidewall rubber (6), toe mouth is filled glue (7), soft triangular rubber core (8) and the double-layer nylon infantees (10) in outside, fill carcass ply (2) and the toe mouth in glue (7) and outside strengthens, between wirecord fabric (3), double-layer nylon infantees (10) is set at described toe mouth, this double-layer nylon infantees (10) encases carcass ply (2) and toe mouth reinforcement wirecord fabric (3) outer upper end termination, between described soft triangular rubber core (8) and double-layer nylon infantees (10), be provided with insulation rubber (11), the upper end of described insulation rubber (11) and toe mouth are filled the inside upper part of glue (7) and are close to, the adjacent described carcass ply in lower end (2) of this insulation rubber (11) and toe mouth are strengthened the outer upper end termination of wirecord fabric (3).
Adopt above structure, between soft triangular rubber core in tire toe structure and double-layer nylon infantees, set firmly insulation rubber, the shearing stress that the outer point that can effectively disperse carcass ply and toe mouth to strengthen wirecord fabric is upwards dispersed in the time of pressurized, further improve the rich ability of song of tire, can reduce the wearing and tearing to double-layer nylon infantees, extend the service life of tire simultaneously.
As preferably, it is interior low outer high step-like that the lower end of described insulation rubber (11) is, the low order termination of the adjacent insulation rubber in outer upper end termination (11) lower end of described carcass ply (2), described toe mouth is strengthened the high-order termination of the adjacent insulation rubber in outer upper end termination (11) lower end of wirecord fabric (3).Adopt above structure, can promote the dispersibility of toe mouth position stress, reduce the rich distortion of song of toe mouth position, can further extend the service life of tire.
For the stress of zygodactyl mouth position plays the effect of postponing and disperseing, as preferably, the outer upper end termination of wirecord fabric (3) is strengthened in the outer upper end termination of described carcass ply (2) lower than toe mouth, and diff-H is 10mm～15mm.
Beneficial effect: the utility model can improve toe mouth position support performance, can improve the bent rich rigidity in toe mouth position under high load condition, improves endpoint location stress dispersion ability, reduces endpoint location stress and concentrates the destruction to tire.
