Pneumatic tire 10.00 P20 tire with ply rating 16

摘要

The utility model relates to the field of automobile tires, in particular, to the design of truck tires, radial pneumatic radial tires, can be used in the tire industry for tires of 10.00 P 20 with a layering of 16 tires and 10.00 P 20 with a maximum allowable load of 3000 kgf per tire tire pressure is 8,1 kgf / cm. The task of this utility model is to design a tire of a pneumatic radial tire 10.00 R 20 with a ply rate of 16 with such a ratio of structural parameters of the carcass and bead, to Thoraya be allowed to expand the arsenal of technical means, while maintaining the overall health and performance of the tire, meeting the requirements of GOST 5513-97 "pneumatic tires for trucks, trailers for them, buses and trolleybuses. Specifications "in relation to tires 10.00 P 20 norm of plyiness 16. To achieve a technical result, a pneumatic tire of radial design 10.00 P 20 is developed by the norm of plyiness 16, containing protector, belt, sidewalls, carcass, bead, consisting of outer and inner groups of rubberized cord layers , side rings, filling cord, characterized in that the frame is made of four layers of rubberized cord (3 layers of the inner group of cord layers wrapped on the side ring, and 1 layer in the outer group wrapped under rotary ring), while the skeleton is made of cord layers with a tensile strength of yarn 30 kG / filament and a total frequency of filaments of cord layers 376 ± 12 over a length of 100 mm, the ratio of the frequencies of the filaments in the outer layers of the skeleton cord to the frequency of the filaments in the inner layers of the skeleton 0, 8, the ratio of the frequencies of the threads of the duplicated side tapes (located between the twists of the layers of the inner group of the carcass layers and the outer layer of the carcass) and the single side bead tape (located on the outer side of the outer layer of the carcass) to the total frequency of the filaments in the carcass layers is 0.2, the ratio duplicate chafer thickness to the total thickness of the carcass plies, 0.46, performing bead one bead ring comprising 110 bead wires in a section of the bead core.
