Problems solved by technology

However, pneumatic tires also have some defects due to their own characteristics: as the tire pressure is not suitable under different temperature and road conditions, it will affect the condition of the tires, especially in the process of use, there are safety hazards such as tire blowouts, and accidents caused by tire blowouts often cause serious problems. Causing casualties, so the technicians in the field of tires began to develop non-pneumatic tires that do not blow out. Although non-pneumatic tires can avoid the risk of tire blowouts, the variety of internal structures makes the weight of the tire almost double, and the cost cannot be compared with rubber inflation. tire comparable

Embodiment 1

[0085] Take the type II support structure as an example to describe. like figure 1 As shown, there are two circumferential supports inside the tire, and polyurethane is used as the tire manufacturing material. The tire manufacturing method is as follows:

[0086] Steel wire belt layer: Please refer to CN201910815970.X and CN201911421934.1 for the specific process.

[0087] The entanglement of the child and mother's carcass:

[0088] Use special equipment to wind the sub-carcass. When winding, fix one end of the 3+9+15×0.175+0.15NT cord on a single inner core. The wound godet runs continuously through the inner ring of the inner core. When winding, control the gap according to the different requirements of the carcass design. After the winding is completed, the end point is fixed, such as Figure 12 shown. Wind all independent inner cores to complete, such as Image 6 shown.

[0089] Use special equipment to wrap the mother carcass. When winding, fix one end of the 3+...

Embodiment 2

[0095] Taking the polyurethane material with type II support structure as an example, nylon cord is used as the skeleton material of the mother and child carcass cord, and the manufacturing method is as follows:

[0096] Steel wire belt layer: Please refer to CN201910815970.X and CN201911421934.1 for the specific process.

[0097] The entanglement of the child and mother's carcass:

[0098] Use special equipment to wind the sub-carcass. When winding, one end of the polymer fiber (nylon) cord is fixed on a single inner core. The wound godet runs continuously through the inner ring of the inner core. When winding, control the gap according to the different requirements of the carcass design. After the winding is completed, the end point is fixed, such as Figure 12 shown. Wind all independent inner cores to complete, such as Image 6 shown.

[0099] Use special equipment to wrap the mother carcass. When winding, fix one end of the polymer fiber (nylon) cord to the outerm...

Embodiment 3

[0105] Taking tires with support ribs as an example, the manufacturing method is as follows:

[0106] Steel wire belt layer: Please refer to CN201910815970.X and CN201911421934.1 for the specific process.

[0107] The entanglement of the child and mother's carcass:

[0108] Use special equipment to wind the sub-carcass. When winding, fix one end of the 3+9+15×0.175+0.15NT cord on a single inner core. The wound godet runs continuously through the inner ring of the inner core. When winding, control the gap according to the different requirements of the carcass design. After the winding is completed, the end point is fixed, such as Figure 12 shown. Wind all independent inner cores to complete, such as Image 6 shown.

[0109] Use special equipment to wrap the mother carcass. When winding, fix one end of the 3+9+15×0.175+0.15NT cord to the outermost ring of the inner core. The cord is wound around several cores, passing the wound godets continuously through the inner rin...

Abstract

The invention provides a novel dual-purpose tire which can be used for a long time under an inflation or non-inflation condition and a molding process of the novel dual-purpose tire. The tire sequentially comprises a tread, a belted layer, a primary tire body, a secondary tire body, an inner supporting body, an inner pressure-bearing ring, a steel ring, a breathing hole and the like from outside to inside, wherein the parts are tightly combined into a whole through a curing cross-linking reaction by adopting polymer liquid mixtures with different formulas, so that different requirements of the parts of the tire on material performance are met, and rapid forming of the tire is ensured. The tire production efficiency is high, and the production cost can be effectively reduced. The tire is suitable for tires of heavy trucks, trailers, light trucks, off-road vehicles, ATVs, buses, airplanes, agriculture, mining, bicycles, motorcycles and passenger vehicles.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a dual-purpose tire and a manufacturing process thereof. Background technique [0002] With the development of the tire industry, pneumatic tires have become a general-purpose tire because of their excellent characteristics, which are widely used in various vehicles, machinery, aircraft and mobile equipment. However, pneumatic tires also have some defects due to their own characteristics: for example, inappropriate tire pressure under different temperature and road conditions will affect the condition of the tire, especially in the process of use, there are safety hazards such as tire blowout, accidents caused by tire blowouts often cause accidents. Cause casualties, so the technicians in the tire field began to develop non-pneumatic tires that do not puncture. Although non-pneumatic tires can avoid the risk of puncture, the variety of internal structures makes the weight of the ti...
