Embodiment Construction

[0029] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] An all-steel radial tire with a two-layer U-shaped steel wire reinforced bead, the tire includes a tire crown, a tire shoulder, a carcass ply 1, an inner liner 2, a belt layer and a bead. Such as figure 1 As shown, the bead includes a bead 2, an apex 3 and a spigot protector 4, and the carcass ply 1 is turned up with the bead 2, and the two sides of the carcass ply 1 are respectively provided with first steel wires The cord reinforcement layer 5 and the second steel cord reinforcement layer 6 . The first steel cord reinforcement layer 5 is fitted between the carcass cord layer 1 and the inner liner layer 2, the cross section of the first steel cord reinforcement layer 5 bypassing the bead ring 7 is U-shaped, and the first steel cord reinforcement layer 5 The inner end point is higher than the turn-up end point of the car...

Abstract

The invention relates to an all-steel radial tire capable of adjusting the steel ladle structure of a tire bead and a preparation method of the tire, and in particular relates to the all-steel radial tire with the tire bead reinforced by two layers of U-shaped steel wires. The all-steel radial tire comprises a tire crown, a tire shoulder, a tire body cord fabric layer, an inner liner layer, a belt layer and the tire bead, wherein the tire bead comprises steel wire rings, bead filler and seam allowance protecting adhesive; the steel wire rings are reversely wrapped by the tire body cord fabric layer; a first steel wire cord fabric reinforcement layer and a second steel wire cord fabric reinforcement layer are respectively arranged on two sides of the tire body cord fabric layer; the first steel wire cord fabric reinforcement layer is boned between the tire body cord fabric layer and the inner liner layer; the second steel wire cord fabric reinforcement layer is arranged between the tire body cord fabric layer on the outer side of the tire bead and the bead filler. According to the all-steel radial tire with the designed tire bead, the flaws at the positions of seam allowances are effectively reduced, so that the tire rates of return and the compensate for checking tire wrong are decreased. Thus, the loss of an enterprise is reduced and the cyclic utilization rate of the tire is effectively improved. As a result, the all-steel radial tire provided by the invention conforms to the current enterprise philosophy of sustainable development and economy.

Description

technical field [0001] The invention relates to the field of manufacturing all-steel radial tires, in particular to an all-steel radial tire with an adjusted bead ladle structure and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the requirements for tire performance are getting higher and higher. Therefore, compared with bias tires, all-steel radial tires with good wear resistance and fuel economy have achieved rapid development and have become the tire industry mainstream products. However, bead problems during the running of all-steel radial tires will seriously affect the performance and service life of the tires, so the design and improvement of bead structures has become one of the key projects of major tire companies at home and abroad. The carcass cords of radial tires are radially arranged, and the sidewall is relatively soft. During the running of the tire, the bead is subjected to a large force, ...
