Problems solved by technology

[0002] Under the conditions of severe overloading and high air pressure in the current transportation market, the supporting performance of the existing bead structure is insufficient, the deformation is large and it is bent on the rim flange, and the turn-up carcass cord and spigot reinforcement steel wire near the rim flange area The cord is compressed and deformed, which is easy to form stress concentration, resulting in quality problems such as ring voids, ring cracks, and blasting of the tire

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as figure 1 As shown, the new all-steel radial tire with heavy-duty bead structure includes a bead structure. The bead structure includes an apex rubber core, and the outside of the rubber core is wrapped with a carcass cord 2. The outer part of the azimuth is wrapped with the outer bead reinforcement cord 5, the surface of the carcass cord 2 located at the inner side of the bead structure is provided with the inner bead reinforcement cord 3, and the inner part of the bead structure is also provided with a reinforcement covering the outer bead. Cord 5 and inner fiber cord 4 on the outside of inner mouth reinforcement cord 3, bead structure end surface orientation and bead structure inner orientation are also provided with covering outer mouth opening reinforcement cord 5, inner mouth opening reinforcement cord 3, inner fiber cord 4 and carcass The inner lining ...

Abstract

The invention discloses a full steel radial brand-new tire with a heavy duty tire bead structure. The tire comprises a tire bead structure, which comprises a triangular rubber core. A carcass cord layer is wrapped on the rubber core. The external part, which is arranged on the end face direction of the tire bead structure, of the carcass cord is wrapped by an external opening reinforcing cord. Thesurface of the part, which is arranged on the inner side of the tire bead structure, is provided with an internal opening reinforcing cord. The internal side direction of the tire bead structure is also provided with an internal fibrous cord covered on the external opening reinforcing cord and the internal opening reinforcing cord, and the external side direction of the tire bead structure is also provided with an external fibrous cord covered on the external opening reinforcing cord. The structure has the advantages that through the application of internal and external one layer or multilayer fibrous cords and internal and external two opening reinforcing cords, the end points of tire beads are arranged between the external opening reinforcing cord and the internal opening reinforcing cord, the stress on the tire bead ends is effectively dispersed, and the damage of the carcass ends in the early stage is avoided.

Description

technical field [0001] The invention relates to the technical field of tire structure, in particular to a brand-new all-steel radial tire with a heavy-duty bead structure. Background technique [0002] Under the conditions of severe overloading and high air pressure in the current transportation market, the supporting performance of the existing bead structure is insufficient, the deformation is large and it is bent on the rim flange. The cord is compressed and deformed, which is easy to form stress concentration, resulting in quality problems such as ring voids, ring cracks, and blasting of the tire. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, to provide a new all-steel radial heavy-duty bead structure tire that is resistant to flexural deformation and eliminates stress concentration. By adjusting the material distribution of the bead part of the tire, the load resistance of the bead part of the...
