Embodiment 1

[0035] A load radial tire, comprising a carcass 1 composed of 3 layers of aramid fiber plies 11, 3 layers of belt layers 4, 2 layers of nylon covering layers 3, bead 2, the angle of the aramid fiber plies 11 is 75°, The difference between each layer of aramid ply 11 is 10 mm, the calendering density of the aramid ply 11 is 110 strands / 100 mm, and the thickness of the rubber coating is 1.4 mm.

Embodiment 2

[0037] The structure of the radial truck tire is the same as that of Example 1, except that it includes a carcass 1 composed of 4 layers of aramid ply 11, the angle of the aramid ply 11 is 85°, and the distance between each layer of aramid ply 11 is The difference is 12mm, and the thickness of the glue is 1.2mm.

Embodiment 3

[0039] The structure of the load radial tire is the same as that of Example 1, except that it includes a carcass 1 composed of five layers of aramid ply 11, the angle of the aramid ply 11 is 88°, and the distance between each layer of aramid ply 11 is The difference is 15mm, and the thickness of the glue is 1.1mm.

Abstract

The invention discloses a truck radial tire, and belongs to the field of truck tires. The tire comprises a tire body and a tire bead, the tire body is composed of aramid cord fabric layers, the tire body comprises at least three aramid cord fabric layers, the multiple aramid cord fabric layers are arranged in a crossed mode, and the angle of each aramid cord fabric layer is not smaller than 70 degrees and not larger than 90 degrees. The load-bearing radial wheel tire is applied to the aspect of load-bearing tires, solves the problems that an existing load-bearing radial wheel tire cannot be good in load-bearing performance, high in strength, long in service life, light in weight and low in oil consumption, and has the advantages of being excellent in load-bearing performance, light in weight, small in rolling resistance and low in oil consumption.

Description

technical field [0001] The invention belongs to the field of truck tires, in particular to a truck radial tire. Background technique [0002] After years of development, the tire industry has now entered the stage of scientific and technological innovation. The world's major tire research and manufacturing centers are constantly developing and applying new technologies, new raw materials and new processes to produce higher-performance tires. Traditional truck radial tires all adopt all-steel carcass structure. However, with the enhancement of people's awareness of environmental protection, radial tires are promoted to "green" radial tires, which require light weight, low rolling resistance, low fuel consumption, and retreadability. In order to improve the load capacity and service life of the tire, it is necessary to break the traditional design concept, make breakthroughs and innovations in the tire structure and construction design, introduce new skeleton materials, reduce...
