Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a explosion-proof tire. Background Art

[0002] The conventional explosion-proof tires have thickened tire sidewalls. When the tire loses air pressure, the tire sidewalls can still support the weight of the vehicle. The explosion-proof tires will not be severely deformed. Therefore, explosions of the explosion-proof tires will not seriously affect the driving of the vehicle. Although the explosion-proof tires in the prior art can reduce serious accidents caused by explosions, the explosion-proof tires in the prior art still do not have the function of long-distance driving in the event of air leakage. Utility Model Content

[0003] The utility model aims to provide a explosion-proof tire to solve the problems in the prior art.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a explosion-proof tire, comprising a wheel hub, an outer tire and a pneumatic tire, the outer tire being arranged on and covering the circumferential side wall of the wheel hub, the pneumatic tire being arranged between the outer tire and the wheel hub, the interior of the pneumatic tire being provided with a partition plate 1 arranged along the circumference of the pneumatic tire, the partition plate 1 dividing the inner cavity of the pneumatic tire into two equal-sized left and right airtight chambers, the partition plate 1 and the pneumatic tire being an integral structure, the interior of each airtight chamber being provided with a plurality of partition plates 2 distributed equidistantly around the center of the pneumatic tire, the partition plate 2 dividing the airtight chamber into a plurality of equal-sized explosion-proof cavities, the partition plate 2 and the pneumatic tire being an integral structure, the inner side of the pneumatic tire being provided with one-way valves equal in number to the explosion-proof cavities, and each one-way valve corresponding to one explosion-proof cavity.

[0005] Preferably, the thickness of the partition plate 1 is greater than the thickness of the pneumatic tire.

[0006] Preferably, the thickness of the second partition plate is equal to the thickness of the pneumatic tire.

[0007] Preferably, the outer tire and the pneumatic tire are made of a synthetic rubber material with high heat resistance.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the pneumatic tire of the utility model forms two rows of explosion-proof chambers inside the pneumatic tire through the partition plate 1 and the partition plate 2 inside the pneumatic tire. Even if the explosion-proof chamber at any position is punctured and leaks air by a sharp object, the other explosion-proof chamber parallel to it can still play a supporting role, thereby ensuring that the tire still has the function of long-distance travel after being punctured and leaked.

[0009] Since the thickness of partition plate 1 is greater than that of the pneumatic tire, the strength of the inner side of the pneumatic tire is greater than that of other positions of the pneumatic tire. Under the traction of partition plate 1, when the pneumatic tire is inflated with gas, the deformation degree of the inner side of the pneumatic tire will be lower than that of other positions, thereby forming a depression on the inner side of the pneumatic tire. This method can prevent the pneumatic tire from easily contacting the wheel hub, forming a gap between the pneumatic tire and the wheel hub, thereby reducing the friction of the wheel hub on the pneumatic tire.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0015] See also Figure 1-2In an embodiment of the utility model, a explosion-proof tire comprises a wheel hub 1, an outer tire 2 and an air tire 3, the outer tire 2 is arranged on and covered on the circumferential side wall of the wheel hub 1, the air tire 3 is arranged between the outer tire 2 and the wheel hub 1, and a partition plate 6 arranged along the circumference of the air tire 3 is arranged inside the air tire 3, the partition plate 6 divides the inner cavity of the air tire 3 into two equal-sized left and right airtight chambers 4, the partition plate 6 and the air tire 3 are an integrated structure, and the interior of each airtight chamber 4 is provided with a plurality of partition plates 27 distributed equidistantly around the center of the air tire 3, the partition plates 27 divide the airtight chamber 4 into a plurality of equal-sized explosion-proof chambers 8, the partition plates 27 and the air tire 3 are an integrated structure, and the inner side of the air tire 3 is installed with a number of one-way valves 5 equal to the number of explosion-proof chambers 8, and each one-way valve 5 corresponds to one explosion-proof chamber 8.

[0016] The thickness of the partition plate 1 6 is greater than the thickness of the pneumatic tire 3 , and the thickness of the partition plate 2 7 is equal to the thickness of the pneumatic tire 3 .

[0017] The outer tire 2 and the pneumatic tire 3 are made of a highly heat-resistant synthetic rubber material.

[0018] The working principle of the utility model is as follows: the pneumatic tire 3 of the utility model forms two rows of explosion-proof chambers 8 inside the pneumatic tire 3 through the partition plate 1 6 and the partition plate 2 7 inside the pneumatic tire 3. Even if the explosion-proof chamber 8 at any position is punctured and leaks air by a sharp object, the other explosion-proof chamber 8 parallel to it can still play a supporting role, thereby ensuring that the tire still has the function of long-distance travel after being punctured and leaked.

[0019] Since the thickness of the partition plate 6 is greater than that of the pneumatic tire 3, the strength of the inner side of the pneumatic tire 3 is greater than that of other positions of the pneumatic tire 3. Under the traction of the partition plate 6, when the pneumatic tire 3 is inflated with gas, the deformation degree of the inner side of the pneumatic tire 3 will be lower than that of other positions, so that a depression is formed on the inner side of the pneumatic tire 3. In this way, the pneumatic tire 3 is not easy to contact with the wheel hub 1, and a gap is formed between the pneumatic tire 3 and the wheel hub 1, thereby reducing the friction of the wheel hub 1 on the pneumatic tire 3.
