Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a microporous solid tire capable of continuous operation. Background Art

[0002] With the continuous advancement of industrialization, the demand for material transportation in various factories is constantly increasing, which puts higher requirements on forklift tires. Compared with pneumatic tires, solid tires have the advantages of high load and maintenance-free, but if you want sustainable operation, this puts higher requirements on solid tires.

[0003] The durability of tires has a great impact on the continuous operation of vehicles. The better the durability of the tire, the longer the continuous operation time. The carcass of solid tires is solid, without cords as the skeleton, and does not need to be inflated, so no inner tube or airtight layer is required. The raw material is made of a special rubber material, except for a small hollow in the middle to maintain the center of gravity, the whole is solid. Tires made in this way can play the role of anti-nail and anti-puncture in harsh environments.

[0004] The damage of solid tires is usually cracking on the sidewall or bulging on the crown. The reason is that heat accumulates quickly during operation and the heat dissipation efficiency is low, which leads to excessive internal temperature of the tire, resulting in thermal cracking and damage to the tire structure. How to improve the heat dissipation efficiency of solid tires and reduce internal heat generation is the key to improving the durability of solid tires.

[0005] Therefore, a microporous solid tire with sustainable operation is proposed. Summary of the invention

[0006] The utility model aims to provide a microporous solid tire that can operate continuously. The solid tire increases the heat dissipation performance of the solid tire to a certain extent by adding a microporous design and a three-stage tire body, so that the tire is not easily damaged by heat and deformation during continuous operation.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A microporous solid tire capable of continuous operation, comprising a tire body, wherein the tire body is composed of three sections, which are, from bottom to top, a base rubber, a tread rubber and a tire core rubber;

[0009] The carcass is provided with micropores, the diameter of which is 2-3 mm;

[0010] The length of the micropores is one quarter of the width of the tire body section.

[0011] The carcass is provided with a waterproof line, and the base rubber is provided from the ring opening of the carcass to the upper end of the waterproof line.

[0012] The carcass is provided with an anti-scratch line, and the tread rubber is provided from the crown of the carcass to the lower end of the anti-scratch line.

[0013] The tire core rubber is located between the base rubber and the tread rubber.

[0014] The carcass is provided with pattern blocks.

[0015] The number of ground contact pairs of the tread blocks under static load is 3.4 pairs.

[0016] The micro holes are arranged on the anti-scratch line, and each of the pattern blocks corresponds to two micro holes.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] Excellent heat dissipation capability, anti-scratch pinhole design increases tire heat dissipation and reduces internal thermal cracking caused by high temperature;

[0019] The ride is smoother. Compared with the large tread block design of traditional solid tires, the small tread block design can improve the driving feel of the tire host and reduce the bumpy feeling caused by large tread patterns and wide tread grooves.

[0020] Excellent traction and stability: The increase in the number of pattern logarithms increases the tire contact area, disperses the ground pressure, and has excellent traction and lateral stability;

[0021] The durability performance is better, and the durability time is increased by 10-20% compared with ordinary tires of the same specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1-2 , the utility model provides a technical solution:

[0027] A microporous solid tire capable of continuous operation, comprising a tire body, wherein the tire body is composed of three sections, and the tire body structure adopts a three-section combination, from the bead to the upper end of the waterproof line 7 is a base rubber 3, from the crown to the lower end of the anti-scratch line 6 is a tread rubber 2, and the rest is a tire core rubber 1;

[0028] The tire body is provided with micro-holes 4, which are arranged at the friction line 6, and the diameter of the hole is 2-3mm. At the same time, the length of the micro-hole 4 is one-fourth of the width of the tire section. The tire body is provided with pattern blocks 5, and the number of ground contact pairs of the pattern blocks 5 under static load is 3.4 pairs. The number of ground contact pairs increases the tire contact area, improves the tire traction performance, and improves the driver's comfort. Each pattern block 5 corresponds to two micro-holes 4, which are evenly distributed around the circumference. Since the pinhole is located at the junction of the tire core rubber 2 and the tread rubber 1, which is the area where the tread rubber 1 generates heat and deforms severely, the design of the micro-hole 4 can increase the heat dissipation efficiency and discharge the heat outward along the pores.

[0029] Working principle:

[0030] The intersection area of ​​the base rubber 3 and the tire core rubber 2 is set at the upper end of the waterproof line 7. Since the force rectangle at the bead opening is the largest, it is easy to cause the solid tire to tear. This area uses the base rubber with the highest hardness and strong rigidity to improve the matching performance between the tire and the rim.

[0031] The area from the upper end of the waterproof line 7 to the lower end of the anti-scratch line 6 is a low deformation area of ​​the solid tire. This area uses a tire core rubber with medium hardness and small thermal deformation. First, it ensures a uniform transition between the base rubber 3 and the tread rubber 1. Second, it has good elasticity and reduces the impact of the solid tire on the forklift.

[0032] The intersection area of ​​the tread rubber 1 and the tire core rubber 2 is set at the anti-scratch line 6, and the tread 1 extends to 20-30mm below the pattern block 5, which effectively ensures the wear resistance and puncture resistance of the tread rubber;

[0033] The tire will produce bumps during driving, especially on uneven roads. The tire tread blocks 5 of the present invention adopt a "small and numerous" tread block design, and the tread blocks 5 are narrow, while the traditional tread block design mostly adopts a "large and few" tread block design, with wide tread blocks. The number of tread blocks 5 is increased, and the spacing between individual tread blocks 5 is reduced. The increase in the number of tread blocks 5 is beneficial to heat dissipation during use.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
