Abstract
The utility model discloses an all steel radial tire with winding hat strip, including tire tread portion, from the tire lateral wall that tread portion extends, connect in the bead portion of tire lateral wall, tread portion includes matrix curtain layer, two-layer belted layer, sets up the zero degree hat strip between two-layer belted layer. The radial tire increases the strength of the tire body and reduces the deformation of the belted layer when stressed by the constraint effect of the zero-degree crown band strip on the belted layer, and can improve the durability and the retreading capability of the tire; meanwhile, the footprint and pressure distribution of the wide-base tire can be improved, and the abrasion of the tire is improved. The rolling resistance of the tire can be reduced by reducing the deformation, and the fuel economy is improved.
Description
Technical field
The utility model relates to a kind of tire, relates in particular to a kind of all-steel radial tyre with engage thread winding cap strip.
Background technology
The radial-ply tyre of prior art generally comprises the main body plies cords of arranging in the radial mode, this plies cords is turned back at bead core via lower tire side wall from tyre surface, along tire circumferential direction, the secondary bracing ply of one deck with respect to tire circumferential direction inclination 20-40 degree is set at the carcass plies outer circumferential side, at the outer circumferential side winding steel wire cord of inclination bracing ply, forms main bracing ply.Deforming when bracing ply is stressed, affect the durability of tire and renovation ability, reduce tire wear.Increase tire drag.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of band and reduces bundle layer stress deformation, promotes the all-steel radial tire of tyre last.
The utility model is achieved by the following technical solution: the all-steel radial tire that the utlity model has winding cap strip, comprise tire face, the lower tire side wall extended from fetus face, be connected in lower tire side wall and there is the bead part of bead core, fetus face comprises carcass layer, at least two-layer bracing ply, zero degree cap strip, described zero degree cap strip be arranged between at least two-layer bracing ply or on.
Preferably, the zero degree cap strip is wound around and is made by least one steel cord screw thread.
Preferably, the zero degree cap strip is along the parallel spiral curling arrangement of tire circumferential direction one deck at least.
Compared with prior art, the utility model fetus face increases zero degree cap strip structure, and the constraint effect by the zero degree cap strip to bracing ply increases carcass strength, and the distortion when minimizing bracing ply is stressed, can promote tyre last and renovation ability; Can improve wide base tire ground connection impression and distribution of pressure, promote tire wear simultaneously.Also can reduce tire drag by reducing deformation, promote fuel economy.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model radial-ply tyre carcass bracing ply, cap strip arrangement mode.
The specific embodiment
As shown in Figure 1, the all-steel radial tire that the utlity model has winding cap strip comprises tire face (not shown), from tire protector section two ends along radial direction crooked connected lower tire side wall (not shown), be connected in the bead part (not shown) that the lower tire side wall inner periphery has ring-type bead core (not shown), fetus face comprises casingply 1, the first bracing ply 2, the second bracing ply 3, the 3rd bracing ply 4 and zero degree cap strip 5.Casingply 1 turns back at bead core after lower tire side wall from fetus face, casingply 1 is the linear formula of meridian and arranges, the first bracing ply 2, the second bracing ply 3, the 3rd bracing ply 4 are arranged on casingply 1, and zero degree cap strip 5 is arranged between the first bracing ply 2, the second bracing ply 3.5 pairs of the first bracing plys 1 of zero degree cap strip play the constraint effect, and the constraint effect by cap strip to the first bracing ply 2 increases carcass strength, and the distortion when minimizing bracing ply is stressed promotes tyre last and renovation ability; Change tire ground connection impression and distribution of pressure simultaneously, promote tire wear.Also can reduce tire drag by reducing deformation, promote fuel economy.
Certainly, zero degree cap strip 5 also can be arranged between the second bracing ply 3 and the 3rd bracing ply 4, perhaps be arranged on the 3rd bracing ply 4, thereby the first bracing ply 2, the second bracing ply 3 or the first bracing ply 2, the second bracing ply 3 and the 3rd bracing ply 4 are all played to the constraint effect, further reduce the distortion of bracing ply when stressed.The utility model also can not arrange the 3rd bracing ply.
The steel cord of zero degree cap strip 5 can be wound around and be arranged in a combination by two first spiral twisteds of above steel wire, can certainly make the zero degree cap strip by single steel wire plying twisted spiral winding again.The angle of steel cord is along the circumferential direction 0 degree, zero degree cap strip 5 be arranged on bracing ply or between, along the parallel spiral curling arrangement of tire circumferential direction one deck at least.
Described above is better embodiment of the present utility model; only that the example effect does not limit protection domain of the present utility model, in the distortion that does not depart from spirit of the present utility model, revise and all to fall in the protection domain that the utility model claim limits.
Claims (3)
1. the all-steel radial tire with winding cap strip, comprise tire face, the lower tire side wall extended from fetus face, be connected in lower tire side wall and there is the bead part of bead core, it is characterized in that: fetus face comprises carcass layer, at least two-layer bracing ply, zero degree cap strip, described zero degree cap strip be arranged between at least two-layer bracing ply or on.
2. the all-steel radial tire with winding cap strip as claimed in claim 1 is characterized in that: described zero degree cap strip is wound around and is made by least one steel cord screw thread.
