Solid tire structure

Abstract

The invention discloses a solid tire structure. The solid tire structure comprises two or more rubber materials, wherein a plurality of rubber fixing steel wires are arranged in an inner layer rubber material, wherein each fixing steel wire is obtained by arranging a single layer steel wire. By using single wire arranged structural mode, the side area of the fixed steel wire is smaller so that the rubber material can be prevented from driving the steel wire to move due to the extruding of a lower die to the rubber material during vulcanizing so as to avoid the inclination of the steel wire; moreover, by using the single wire arranged steel wire structure, the bottom area of the steel wire is increased so that a rim and a bead are more uniformly stressed and relative resistance of the rim and the tire lining is enlarged to a certain degree so as to inhibit poor rolling; moreover, by using a single-row steel wire structure, each interior part of the tire is more uniformly stressed so that the steel wires are uneasy to spread or form displacement in high-load and steering state; therefore, the steel wire wrapping cloth is saved, the swelling damage of the tire due to rapid temperature rising caused by relative peristalsis between the steel wire and the rubber material can be also avoided, and the running performance of the tire is improved.

Description

technical field [0001] The invention relates to a solid tire, in particular to a solid tire structure which improves the running temperature rise of the solid tire and improves the durability running performance. Background technique [0002] At present, solid tires are mainly used for forklifts, and the use of forklifts mainly has the following characteristics: [0003] 1. It is used for a long time. As a short-distance moving tool, it is often operated for a long time, and has high requirements for low heat generation performance of the tire; [0004] 2. Frequent turns. The difference between forklifts and ordinary vehicles is that they are only used for short-distance transportation, and the turns and U-turns are very frequent. This will intensify the creep deformation between the rubber material and the rubber material and the fixed steel wire, resulting in Tire temperature rises faster; [0005] 3. The load and road conditions are complex. Forklifts are used in factor...

[0004] 2. Frequent turns. The difference between forklifts and ordinary vehicles is that they are only used for short-distance transportation, and the turns and U-turns are very frequent, which will make the gap between rubber and rubber The creep deformation between the rubber material and the fixed steel wire is intensified, causing the temperature rise of the tire to accelerate;

[0005]3. The load and road conditions are complicated. Forklifts are used in factories, construction sites, mining areas, and waste factories. Pneumatic tires are easy to be punctured and cut, resulting in inability to use

In actual use, this will cause uneven force on the tire as a whole, which will intensify the creep between the tire rubber compound and the fixed steel wire B', which will not only easily cause the movement and extraction of the fixed steel wire B, but also accelerate the temperature rise of the tire, causing the tire Drum kit in advance of use

On the other hand, when the rubber material drives the fixed steel wire B' into the skew of the steel wire (such as image 3 shown), which reduces the inner circumference of the fixed steel wire B’ to a certain extent, making it difficult to install the tire

Moreover, there are many layers of steel wire s1' in this fixed steel wire B' structure, which results in a large local binding force inside and makes it difficult to install the tire.

In addition, in the actual use of the multi-layer steel wire structure, especially when the load is high and the load is constant, the steel wire s1' is easy to scatter. rising material costs
