Embodiment Construction

[0015] The following will be combined with figure 1 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] The present invention provides a kind of dual air pressure tire by improvement here, comprises cover tire 1, middle layer 2, inner tube of a tube 3; 1 and the inner tube 3 are all provided with corresponding air nozzles 4,5 to form double-layer air pressure.

[0017] The double air pressure tire of the present invention, middle layer 2 adopts rubber to make, thickness 1-5 centimetre, can prevent shorter nail from piercing inner tuber. ...

Abstract

The invention discloses a double-pressure tire. The double-pressure tire is characterized by comprising an outer tire, a middle layer and an inner tire, wherein the middle layer is located between the outer tire and the inner tire, so that the outer tire, the middle layer and the inner tire are sequentially wrapped. Air faucets 4 and 5 corresponding to the outer tire and the inner tire are arranged between the outer tire and the inner tire, so as to form dual-layer pressure. The middle layer is made of rubber; the thickness is 1-5 centimeters; and relatively short nails can be prevented from puncturing the inner tire. Two air faucets are arranged on the improved double-pressure tire and correspond to double pressure (the inner tire and the outer tire are aerated); the inner tire is firstly aerated in aeration, and is fully aerated; the outer tire is aerated; if the outer tire is flat in travel, the tire can normally drive due to the action of the middle layer and the inner tire; even if the outer tire is low in air pressure, the outer tire can also be supported through the expansive action of the inner tire on the middle tire, so that the outer tire does not deform; the middle tire is 1-5 centimeters in thickness; and the relatively short nails can be prevented from puncturing the inner tire.

Description

technical field [0001] The invention relates to a vehicle tire, especially a tire with double air pressure. Background technique [0002] Nowadays, with the popularization of automobiles, automobile tires are getting more and more attention. However, automobiles widely use pneumatic tires. While enjoying the fast driving of automobiles, people all over the world are deeply troubled by the problem of tire leakage, and even more suddenly Injured by a flat tire. [0003] Under normal circumstances, the run-flat tire can rely on the hard tire sidewall to support the normal driving of the vehicle for a considerable distance when the tire is deflated or even has zero tire pressure. However, when a sharp and hard object is scratched at high speed, the tire will also blow out, so the term run-flat tire is very one-sided. It's just that the tire wall of this kind of tire is extremely hard, which can reduce the probability of a tire blowout caused by the temperature of the tire wall...
