Problems solved by technology

However, the tires designed with this structure in the reinforcement layer have the following problems during production: the steel cord will stretch to a certain extent when the tire embryo is being molded, shaped, and vulcanized. Independently, for the cord reinforcement layer on each side, the cord reinforcement layer is affected by stretching and has a certain displacement. After several shifts such as molding, shaping, and vulcanization, the finished nylon cord reinforcement layer The actual position of the tire cord is not consistent with the position required by the design, and even the difference is very large, so that the actual dissected tire cord reinforcement layer does not match the design. Different individuals of the same batch of products may also have great differences, and even fail to meet the strength design requirements. Affect the use effect of the reinforcement layer

Embodiment 1

[0016] In the embodiment shown in Fig. 1, the tire with integral ply reinforcement of the present invention includes a carcass, and the carcass is divided into a crown area 4, a shoulder area 3, a sidewall flexing area 2 and a bead area 1; There is a carcass ply 5 in the body, and the radial inner side of the carcass ply 5 extends from the bead area 1 on the side of the carcass across the sidewall flexing area 2, the shoulder area 3 and the crown area 4 to the tire tire. The bead area 1 on the other side of the body is provided with a nylon ply reinforcing layer 6 of an integral structure.

Embodiment 2

[0018] In the embodiment shown in Fig. 2, the tire with integral ply reinforcement of the present invention includes a carcass, and the carcass is divided into a crown area 4, a shoulder area 3, a sidewall flexing area 2 and a bead area 1; There is a carcass ply 5 in the body, and the radial inner side of the carcass ply 5 extends from the sidewall flex zone 2 on one side of the carcass across the shoulder zone 3 and the crown zone 4 to the sidewall on the other side of the carcass. The flexing zone 2 is provided with a nylon cord reinforcing layer 6 of an integral structure.

Embodiment 3

[0020] In the embodiment shown in Fig. 3, the tire with integral ply reinforcement of the present invention includes a carcass, and the carcass is divided into a crown area 4, a shoulder area 3, a sidewall flexing area 2 and a bead area 1; There is a carcass ply 5 in the body, and the radial inner side of the carcass ply 5 extends from the shoulder area 3 on one side of the carcass across the crown area 4 to the shoulder area 3 on the other side of the carcass. Nylon ply reinforcement 6.

Abstract

The invention discloses a tyre with an integral reinforcing layer made of cord fabric, comprising a tyre body which is divided into a tyre tread zone, tyre shoulder zones, a tyre side flexion zone and a tyre bead zone. A cord fabric layer is arranged inside the tyre body; the tyre shoulder zones at the two sides of the tyre, the tyre side flexion, the inner side or the outer side of the cord fabric layer of the tyre body are provided with a reinforcing layer made of cord fabric; the reinforcing layer is an integral nylon cord fabric structure striding over the tyre tread zone from one side of the tyre to the other side. Since the tyre of the invention is arranged to have an integral reinforcing layer made of cord fabric, the interference exerted to the displacement of the cord fabric reinforcing layer by the extension of the steel wire cord fabric in the process of molding, finalizing and vulcanizing the tyre body can be avoided, so the cord fabric reinforcing layer hardly moves, ensuring that the finished cord fabric reinforcing layer is in accordance with the design, therefore the reinforcing effect to the whole tyre body is realized and finally the capability of impact resistance is increased and the chance of sudsing or transforming is decreased.

Description

(1) Technical field: [0001] The invention relates to a tire, in particular to a tire with an integral ply reinforcement. (two) background technology: [0002] The shoulders of existing all-steel radial tires have only one layer of carcass steel cord, and the rest are rubber layers without other skeleton materials. The shoulders are relatively weak. In order to improve the bearing capacity of the shoulders, it is necessary to select appropriate The material acts as a reinforcing layer for the tire. Due to the advantages of high strength, fatigue resistance and impact resistance, nylon cord is widely used in the reinforcement layer of tire shoulders. In traditional tires, one layer of nylon cord reinforcing layer is respectively arranged in the tire shoulder area on both sides of the tire. The reinforcing layers of the shoulders on both sides are symmetrical and independent, and are disconnected in the middle. However, the tires designed with this structure in the reinforcem...
