Gap enters, and is entered by the first gas outlet of the first air guide channel in first inner tube of a tyre；When the pressure of first inner tube of a tyre reaches setting
Pressure after, the compressed air in first inner tube of a tyre acts on the second drive disk of the second check valve, the drive for being subject to the second valve element
Power is more than the elastic force that second spring puts on the second valve element, the second valve element is moved to the direction for opening the second check valve, the
Two valve elements overcome the elastic force of second spring to open the second check valve, the second valve element and the second air guide channel air-guiding gap is occurred；
After second check valve is opened, the compressed air in first inner tube of a tyre is entered by the second air inlet of the second check valve, compressed air warp
Air-guiding gap enters between second valve element and the second air guide channel, is entered by the second gas outlet of the second air guide channel in second
Tire；After the pressure of second inner tube of a tyre reaches the pressure of setting, it is single that the second valve element closes second in the presence of second spring elastic force
To valve；After second closed check valve, the first check valve is closed in the presence of the first spring force；When cover tire pierces through mistake by sharp weapon
During pressure, the first closed check valve, first inner tube of a tyre maintains pressurising state, and first inner tube of a tyre is connect by the first outer support post with cover tire
Touch, first inner tube of a tyre is contacted by the first inner support post with wheel rim 1, runflat by first inner tube of a tyre support motor vehicle, avoid or
Reduce the generation of inclined tire accident；When cover tire, first inner tube of a tyre pierce through decompression by sharp weapon, second inner tube of a tyre maintains pressurising state, the
Second outer support post of two inner tubes of a tyre is connected with the first outer support post of first inner tube of a tyre, and the first outer support post is connected with cover tire；Second
Second inner support post of the inner tube of a tyre is connected with the first inner support post of first inner tube of a tyre, and the first inner support post is connected with wheel rim, runflat
Motor vehicle is supported by second inner tube of a tyre, avoids or reduce the generation of inclined tire accident.
The beneficial effects of the invention are as follows：Runflat include cover tire, first inner tube of a tyre, second inner tube of a tyre, the first check valve and
Second check valve；When cover tire is inflated, first inner tube of a tyre is inflated by the first check valve, and second inner tube of a tyre is inflated by the second check valve；
The check valve of runflat includes the first check valve and the second check valve, and the first check valve includes the first valve body, the first valve
Core, the first spring and the first drive disk；Second check valve includes the second valve body, the second valve element, second spring and second
Drive disk；When cover tire is inflated, the first driving valve element of dish driving first of the first check valve overcomes the elastic force of the first spring to open the
One valve element, using the first check valve to the first tire tube air-inflating；After first tire tube air-inflating, the second driving dish driving of the second check valve
Second valve element overcomes the elastic force of second spring to open the second valve element, using the second check valve to the second tire tube air-inflating；When cover tire quilt
When sharp weapon pierce through decompression, the first closed check valve, first inner tube of a tyre maintains pressurising state, and first inner tube of a tyre passes through the first outer support post
And first inner support post support cover tire；When cover tire, first inner tube of a tyre pierce through decompression by sharp weapon, second inner tube of a tyre maintains pressurising shape
