Abstract

The utility model relates to a heat-insulation double-insurance tire which is characterized by comprising a rubber cover tire, an inner tire, a spare inner tire, a steel ring and a gas generator. The inner layer of the rubber cover tire is provided with a heat-insulation layer made of heat-insulation materials. The spare inner tire is arranged between the steel ring and the inner tire, the gas generator fixed on the steel ring is communicated with the spare inner tire, and a pressure sensor arranged inside the spare inner tire is connected with the gas generator. An air bag module is composed of the spare inner tire, the gas generator, the pressure sensor and the like together. The heat-insulation double-insurance tire is novel and ingenious in structure, when the tire is punctured, chemical substances inside the gas generator can produce a large amount of gas in an extremely short time of puncturing of the tire of a car to aerate the spare inner tire, and the car can be driven to a maintaining shop or a safe area. Consequently, the heat-insulation double-insurance tire can effectively ensure safety of a driver, and is suitable for all motor-driven vehicles and non-power-driven vehicles.

Description

Heat insulation double insurance tire

Technical field:

The utility model relates to a kind of novel tire, a kind of specifically heat insulation double insurance tire.

Background technology:

In recent years, the accident of blowing out of vehicle increases suddenly.According to statistics, blow out in the traffic accident on the express highway and account for more than 70%.Again and again the traffic accident that the accident of blowing out that takes place causes has caused people's vigilance and puzzlement.It is rare to blow out when the vehicle condition road conditions why are all not so well, and the vehicle condition road conditions have all improved now, it is so many on the contrary to blow out? This mainly is because people recognize the vehicle of running at high speed the protection of tire and tire not to be had higher requirement.It is the seed of trouble of blowing out that tire deflation goes.

When going, along with the decline of tire pressure, tire and ground-surface friction are multiplied vehicle at deficency (pressure of tire is lower than the standard tire pressure), and the tire temperature sharply raises, the tire deliquescing, and intensity sharply descends.In this case, if vehicle at low speed driving, also can be hindered tire, and incubation is long, and is disguised big, and harmfulness is more arranged, and buries the major hidden danger of blowing out during for high speed traveling later on.

Existing is that example explains that it is the seed of trouble of blowing out that tire deflation goes with tubeless tires (being radial-ply tyre).Analyze as follows:, be added with layer of steel wire in its carcass plies periphery in order to improve the intensity of tire.The tire intensity of this structure is high, and radiating condition is good, and adaptation is run at high speed.But it also has a great weakness, is afraid of most to run flat.When tire deflation goes, except tire and ground friction are given birth to heat, also can frictional heat between steel wire in the carcass and the tire; Super heat can quicken aging, the distortion of steel wire and rubber; Even internal break so that tomography, cause tire intensity to be destroyed, plant the seed of trouble of blowing out down.

The utility model content:

To above-mentioned situation; The utility model discloses a kind of heat insulation double insurance tire, the internal layer of its outer tyre is provided with thermal insulation layer, between the inner tube of a tyre and steel ring, also is provided with spare inner tube; Spare inner tube and gas generator are communicated with; In the moment that the inner tube of a tyre is blown out, can reach the gas filed effect of spare inner tube of giving automatically, but actv. addresses the above problem.

The utility model solves the technical scheme that its technical matters adopted: a kind of heat insulation double insurance tire; It is characterized in that it is made up of rubbery cover tyre, the inner tube of a tyre, spare inner tube, steel ring and gas generator; The internal layer of described rubbery cover tyre is provided with thermal insulation layer, and thermal insulation layer is to adopt thermal insulation material to process; Described spare inner tube is located between the steel ring and the inner tube of a tyre, and described gas generator is fixed on the steel ring, and gas generator is communicated with spare inner tube, and the spare inner tube the inside also is provided with pressure transducer, and pressure transducer is connected with gas generator; Described spare inner tube, gas generator, pressure transducer constitute air bag module together; Sodium azide (NaN3) or ammonium nitrate materials such as (NH4NO3) are housed in the described spare inner tube; When the inner tube of a tyre was blown out, decomposition reaction can take place rapidly in these materials, produces a large amount of gases, is full of spare tyre.

The beneficial effect of the utility model is: the utility model is in Tyre structure, to be provided with an automatic gas filed spare inner tube; When blowing out; Can blow out through pressure transducer induction, and the chemical substance in the energizing gas producer produces a large amount of gases at the utmost point of automobile flat tire in the short time, inflate to spare inner tube; Can let vehicle ' to maintenance store or safety zone; Can effectively guarantee mental awareness like this, and the utility model is novel, practical, applicable to used power actuated vehicle and non-power-driven vehicle.

Description of drawings:

Below in conjunction with description of drawings and embodiment the utility model is further specified.

Fig. 1 is the utility model structural representation

Fig. 2 is the structural representation of cover tire

Wherein, 1-cover tire, 2-thermal insulation layer, 3-spare inner tube, 4-steel ring, 5-gas generator.

The specific embodiment:

In Fig. 1, first embodiment shown in Figure 2; A kind of heat insulation double insurance tire; It is characterized in that: it is made up of rubbery cover tyre, the inner tube of a tyre, spare inner tube, steel ring and gas generator, and the internal layer of described rubbery cover tyre is provided with thermal insulation layer, and thermal insulation layer is to adopt thermal insulation material to process; Described spare inner tube is located between the steel ring and the inner tube of a tyre, and described gas generator is fixed on the steel ring, and gas generator is communicated with spare inner tube, and the spare inner tube the inside also is provided with pressure transducer, and pressure transducer is connected with gas generator; Described spare inner tube, gas generator, pressure transducer constitute air bag module together; Sodium azide (NaN3) or ammonium nitrate materials such as (NH4NO3) are housed in the described spare inner tube; When the inner tube of a tyre was blown out, decomposition reaction can take place rapidly in these materials, produces a large amount of gases, is full of spare tyre.

In Fig. 1, second embodiment shown in Figure 2, spare inner tube is located between the steel ring and the inner tube of a tyre, and spare inner tube and steel ring are fitted.The internal layer of cover tire is provided with thermal insulation layer, but actv. prevents that the cover tire temperature is too high, blows out and cause the inner tube of a tyre to heat up.

In Fig. 1, the 3rd embodiment shown in Figure 2; When the inner tube of a tyre was blown out for a certain reason, the pressure transducer in the spare inner tube sensed pressure when reducing suddenly, passes the signal to controller fast; Controller receives the signal of pressure transducer and handles; Send ignition signal immediately to trigger gas generator, after gas generator received ignition signal, rapid ignition well produced a large amount of gases and inflates to spare tyre.The chemical substance that produces a large amount of gases in the spare tire can confirm that its consumption, the gas of generation make that not necessarily tire pressure reaches normal value according to the tire pressure of reality, but can keep bicycle and running car to maintenance store or safety zone.The situation generation that can effectively avoid the inner tube of a tyre to blow out suddenly and cause contingency or can't go and block the traffic.

Wherein spare tire can be at the spare tire that repairs and a little renew after using, and old spare tire can be recycled to tire production factory, makees spare tire again, like this can saving in material.
