For reaching above purpose, solution of the present invention is:
A kind of vacuum tubular tire, comprise interior half side, outer half side be connected half side connection transition region, interior half sidely half sidely connect by inside and outside half side connection transition region with being connected, interiorly also be provided with charging valve on half side, charging valve is provided with check valve.
Be attached on the tyre rim under the described interior half side normal condition, outer half side and interior half side between inflation form air-inflation tyre; After blowing out, the internal half side inflation of charging valve, inflation forms air-inflation tyre between the interior half side and steel ring.
Described outer half side rigidity and hardness are respectively all greater than interior half side.
Described check valve is cone valve, when in the tyre-burst blow half side by jack-up after, charging valve and check valve are pulled to the tire outside, cone valve is blocked the gap between charging valve and the steel ring.
Described outer half side employing natural rubber or neoprene, interior half side employing polyurethane (PU), styrene-butadiene block copolymer (SEBS) or polyisoprene.
Described inside and outside half side connection transition region with interior half side and outer half side between one-shot forming, and be smoothly connected, its hardness and rigidity are extremely reduced at interior half side place gradually by outer half side place.
Owing to having adopted such scheme, the present invention has following characteristics: 1. a kind of novel tire, and cooperate gas generator to use, solved that current automobile flat tire can only prevent but the problem that can not effectively process.2. just existing tire is transformed, can't be done very large change to the automobile miscellaneous part, so should use practical basis, can popularize rapidly.3. be pure physical structure substantially, security of system is stable 4. easy to installation and maintenance; 5. cost is compared with original tire does not increase what, and the cycle of designing and developing and manufacturing is short.

The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
Vacuum tubular tire structure of the present invention, such as Fig. 3, Fig. 6, shown in Figure 7, comprising: outer half side 1, interior half side 2, inside and outside half side connection transition region 3, charging valve 4, check valve 5, connect by the inside and outside half side transition region 3 that is connected between outer half side 1 and interior half side 2, form an integral body, its physical structure is complete tubulose, if only see outer half side, be exactly outer half pipe so, half side in corresponding is interior half pipe.Outer half side rigidity is large, and hardness is large, and is similar with conventional vacuum tire now commonly used; Interior half side rigidity is little, and hardness is little, and is similar with rubber inner tube now commonly used, but have more ductibility than it, and intensity is higher.Wherein, charging valve 4 is placed on interior half side 2, is used for to tyre inflating or venting.The check valve 5 that a taper is arranged on the charging valve 4, be connected on the charging valve 4, when in the tyre-burst blow half side 2 by jack-up after, charging valve 4 and cone shaped one-way valve 5 are pulled to the tire outside, cone shaped one-way valve 5 is blocked the gap between charging valve 4 and the steel ring, thereby guarantees that tire no longer leaks gas.
The logical conventional vacuum tire of outer half side material equally is natural rubber or neoprene, and interior half side material is polyurethane (PU), styrene-butadiene block copolymer (SEBS) or polyisoprene.
The interior half side and outer half side transition zone that is connected adopts the one-shot forming processing technology.Its physical property is outer half side and interior half side excessively from outside to inside, rigidity and hardness reduce gradually, and namely this part material is gradual change, and its initial two ends are respectively with outer half side and interior half side smooth affixed.
Such as Fig. 1, Fig. 2, Fig. 4 and shown in Figure 5, the outer half side and common vacuum tyre of vacuum tubular tire does not have any too large difference, and the interior half side common inner tube of a tyre that is similar to.Under normal state, vacuum tubular tire can be worked as vacuum tyre and be used, the interior half side of vacuum tubular tire is close on the steel ring, be as good as with vacuum tyre, and outer half side stronger rigidity makes its right well support performance, tire and steel ring card get the very tight character that benefits again its vacuum tyre, and relative sliding does not occur for tire and steel ring when guaranteeing vehicle wheel rotation.After blowing out, gas generator ignite to discharge gas, by gas passage enter into half side in steel ring and the vacuum tubular tire between, because gas pressure difference and centnifugal force will be with interior half side upwards jack-up, make its tightly be attached to outer half side on, form the double-layer vacuum tire, guarantee that tire no longer leaks gas.
Adopt such scheme, when galloping is blown out suddenly, because breaking, the outside of blowing out do not have gas to exist in the vacuum tubular tire, simultaneously because half side existence in the vacuum tubular tire, the outer half side cut of vacuum tubular tire is by interior half side blocking, as long as guarantee normal air pressure, wheel can normally travel a period of time again, stops until the driver is slowed down safely.
