Huge engineering tire tire bead position reinforcing structure

The utility model relates to a huge engineering tire tire bead position reinforcing structure, include that glue on steel ring, apex strip, matrix, interior line with rubber, side wall and glue in the rim of the mouth, steel ring and apex strip are wrapped up in the matrix, and interior line with rubber complex is in the inboard of matrix, and the side wall is glued compoundly in the outside of matrix, and it has the rim of the mouth to glue still to cover on the tire bead position, and the rim of the mouth is glued both ends and is turned over including the package under the line with rubber tip respectively and glue the outside of tip down, formation overlap structure with the side wall, characterized by: compound between glue on matrix and side wall have a nylon strengthening course, and this nylon strengthening course be one to the multilayer, and the package of turning over is laminated in the outside of matrix. The utility model has the characteristics of think about ingenious, rational in infrastructure, matrix intensity height, nylon strengthening course in matrix outsourcing laminating, with the help of the pliability of nylon yarn, organic laminating improves holistic stretching resistance of tire and resistance to shear characteristic in the matrix outside greatly.
