Toe shape of the mouth as one speaks glue is provided between wirecord fabric, soft triangular rubber core by force, the tire toe structure lower end is encased by toe chewing gum, described
Toe chewing gum outer upper end end is enclosed with sidewall rubber, the toe chewing gum, sidewall rubber and double-layer nylon infantees, soft triangular rubber core it
Between be provided with toe mouth filling glue.
The internal layer upper end termination of the double-layer nylon infantees is higher than outer layer upper end termination, the internal layer of the double-layer nylon infantees
Lower end termination is less than internal layer lower end termination.
The internal layer lower end of the double-layer nylon infantees extends on the inside of tire toe structure, and tire toe structure lower end is wrapped
Firmly.
The double-layer nylon infantees and carcass ply, toe mouth are strengthened being provided with toe shape of the mouth as one speaks glue between wirecord fabric, soft triangle rubber.
The internal layer of the double-layer nylon infantees is wrapped to form " U " type.
The tire toe structure lower end is inclined in set angle.
The beneficial effects of the utility model are：
(1) this utility model simple structure, it is easily manufactured, be conducive to promoting on a large scale；
(2) this utility model increases double-layer nylon infantees, and the internal layer lower end of double-layer nylon infantees is into tire toe structure
Side extends, and tire toe structure lower end is encased, the fatigue resistance of tire toe structure is improve；
(3) this utility model increases toe shape of the mouth as one speaks glue, can effectively disperse carcass ply and toe mouth to strengthen the end of wirecord fabric
The shear stress that point is dissipated when pressurized upwards, improves the rich ability of song of tire, while the abrasion of nylon infantees can be reduced,
Extend the service life of tire；
(4) this utility model aims at the setting of tubeless vehicle tyre, and tire toe structure lower end is inclined to set, with wheel hub
