FIG. 1 is a cross-sectional view of a carcass;

FIG. 2 is an overall view of the present embodiment;

FIG. 3 is an enlarged view taken at A in FIG. 2;

in the figure, 1 tire body, 11 air passages, 12 heat dissipation passages, 13 connecting passages, 14 blocking nets, 120 openings, an inner liner layer, an oxidation resistant layer b and an ultraviolet resistant layer c are arranged.

(V) detailed description of the preferred embodiments

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to the attached fig. 1 to 3, a high temperature resistant tire comprises a tire body 1, an inner liner a is arranged on the inner side of the tire body 1, and the tire body 1 is further internally provided with:

an air passage 11, wherein the air passage 11 is arranged around the central shaft of the tire body 1;

the heat dissipation channel 12, the heat dissipation channel 12 is provided with an opening 120 on the side of the tire crown of the tire body 1, and the air channel 11 is communicated with the heat dissipation channel 12.

In this embodiment, the carcass 1 further includes a belt layer and a ply. Specifically, when a vehicle provided with the high-temperature resistant tire runs on a road, the weight of the vehicle can extrude the tire body 1, the air channel 11 in one side of the tire body 1 close to the ground is extruded, the air in the air channel 11 is extruded from the heat dissipation channel 12 at the position, the heat in the tire body 1 is taken away, when the tire body 1 rolls to the next position, the tire body 1 at the previous position is restored due to the elasticity of the tire body 1, the external air enters the air channel 11 in the tire body again, the exchange of the air flow is realized, the heat dissipation in the tire is promoted in the process, and the tire is more resistant to high temperature.

Further, the air passages 11 are circumferentially arranged around the central axis of the carcass 1 and form a complete circular ring-shaped structure. Therefore, when the air duct 11 at the bottom of the tire body 1 is squeezed, the air flow in the air duct 11 flows upwards and then flows out through the heat dissipation duct 12 above, the flow stroke of the air flow in the air duct 11 is improved, and the air flow can absorb more heat, so that when the air flow is squeezed out from the heat dissipation duct 12, more heat can be taken away from the tire body 1.

Further, the air passages 11 and the heat dissipation passages 12 are provided with a plurality of air passages 11, and the plurality of air passages 11 are communicated with the plurality of heat dissipation passages 12. Wherein, a plurality of air flue 11 are arranged along the width direction of the tire crown, and a plurality of heat dissipation channels 12 are distributed around the circumference of the central shaft of the tire body 1 at equal intervals.

Further, the heat dissipation channel 12 is arranged to penetrate through the tire crown of the tire body 1, a connection channel 13 is further arranged in the tire body 1, the connection channel 13 is arranged along the radial direction of the tire body 1, and the air channel 11 is communicated with the heat dissipation channel 12 through the connection channel 13.

Further, in order to prevent the gravel from entering the air duct 11, in the present embodiment, the heat dissipation duct 12 is provided with the blocking net 14 at the opening 120, and the mesh of the blocking net 14 is small, so as to allow the air flow to pass through, but block the gravel from entering.

Furthermore, when the vehicle is running, the internal temperature of the tire is generally higher than the external temperature, and the high temperature is more likely to cause rubber oxidation, so the internal protection of the tire is more important.

Further, the ultraviolet ray in the sunlight easily causes the tire to crack, and because the thickness of the side wall is minimum, the crack is more easily caused by traffic accidents, therefore, in this embodiment, an ultraviolet resistant layer c is further arranged in the side wall of the carcass 1, and the ultraviolet resistant layer c is a PU silver glue coating.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. Although embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the claims and their equivalents.
