Abstract
The utility model relates to an anti-explosion charging-free wheel inner tube, which is characterized in that the inner tube is made of polyurethane; the inner tube is provided with a hollow cavity group; and the hollow cavity group is arranged in the middle of the inner tube or the outer ring of the inner tube. In the anti-explosion charging-free wheel inner tube, the wheel inner tube is embedded in an outer tube to form interference fit with the outer tube; and the hollow cavity of the outer ring of the inner tube causes the inner tube to be capable of bearing pressure and deformation in the operation process. The wheel inner tube has excellent abrasion resistance. Especially under the working condition that wet media, such as water, oil and the like in the presence, the abrasion resistance of the wheel inner tube is several times or tens of times of that of the common rubber material. The wheel inner tube also has high temperature resistance, can bear the working temperature of 120DEG C and is suitable for high speed, midsummer and long distance use. Meanwhile, the polyurethane wheel inner tube is convenient to process, has the advantages of simple manufacture technology and low production cost and is suitable to popularize and apply on a large scale.
Description
Technical field
The utility model relates to the technical field of inner tube, specifically a kind of explosion-proof inner tube of exempting to inflate.
Background technology
At present, the inside of the general outer tyre of motor tire also has one to be filled with the compressed-air actuated inner tube of a tyre.Its major defect is to be easy to generate high temperature in the driving process, and incompatibility is run at high speed, and can not fully guarantee the safety of going, and the inner tube of a tyre is in stretched condition during use in tire, slightly receives puncture just to form aperture, and makes the tire rapid depressurization.Cause accident such as blow out in the process of moving easily, cause potential safety hazard.
Summary of the invention
The purpose of the utility model is to provide a kind of improved explosion-proof inner tube of exempting to inflate; It can overcome, and the inner tube of a tyre is easy to generate high temperature in the process of moving in the prior art; Incompatibility is run at high speed, and can not fully guarantee the safety of going, the some shortcomings of blowing out easily.
To achieve these goals, the technical scheme of the utility model is: a kind of explosion-proof inner tube of exempting to inflate, and it is characterized in that: the described inner tube of a tyre is processed by polyurethane, this inner tube of a tyre, cavity groups is arranged on the middle part of the inner tube of a tyre or the outer ring of the inner tube of a tyre.
During use, the inner tube of the utility model is processed by polyurethane, and the inner tube of a tyre is provided with cavity groups, and cavity groups comprises even number cavity row and odd number cavity row, and wherein even number cavity row are crisscross arranged with odd number cavity row.The inner tube of the utility model is embedded in the cover tire; Form interference fit with cover tire; The cavity row of inner tube of a tyre outer ring make the inner tube of a tyre in operational process, can bear pressure and distortion; This inner tube wear resisting property is superior, and particularly under the service conditions that has water, wet goods wetted media to exist, its resistance to abrasion is several times to tens times of General Purpose Rubber material often.This inner tube also has heat-resisting quantity, can bear 120 ℃ operating temperature, adapts to high speed, midsummer and long-distance use.The polyurethane inner tube is easy to process simultaneously, and manufacture craft is simple, and productive costs is low, is suitable for large-scale promotion application.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the another structural representation of the utility model one embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
The utility model is described explosion-proofly to be exempted to inflate inner tube and is processed by polyurethane, and this inner tube of a tyre 1 is provided with cavity groups, and cavity groups is arranged on the middle part of the inner tube of a tyre or the outer ring of the inner tube of a tyre.The outer ring of the inner tube of a tyre is provided with cavity groups, and cavity groups is made up of at least 2 row cavitys, and cavity is listed as the circumferencial direction setting along inner tube of a tyre outer ring, and wherein even number cavity row are crisscross arranged with odd number cavity row.The cavity row include 5-30 cavity 2, and the diameter of cavity is 3mm-5cm, equidistant being distributed on the same circumference of cavity in the same cavity row.Polyurethane adopts thermoplastic polyurethane elastic body (TPU), and shore a hardness is 70-77.
In force, cavity can rounded or hexagon, and above-mentioned cavity is the cellular outer ring that is distributed on the inner tube of a tyre; Inner tube is embedded in the cover tire, forms interference fit with cover tire, and the cavity row of inner tube of a tyre outer ring make the inner tube of a tyre in operational process, can bear pressure and distortion; Can disperse its suffered pressure in time, fast in the process of moving; Strengthen the elasticity and the tolerance of the inner tube of a tyre, prolonged its service life, can reach 8-10.This inner tube wear resisting property is superior, and particularly under the service conditions that has water, wet goods wetted media to exist, its resistance to abrasion is several times to tens times of General Purpose Rubber material often.This inner tube also has heat-resisting quantity, can bear 120 ℃ operating temperature, adapts to high speed, midsummer and long-distance use.The polyurethane inner tube is easy to process simultaneously, and manufacture craft is simple, and productive costs is low, is suitable for large-scale promotion application.
