Connection.
The using method of runflat check valve is:After cover tire pressurising reaches the pressure of setting, the compressed air in cover tire is made
For the first drive disk of the first check valve, the driving force that the first valve element is subject to is made to put on the first valve element more than the first spring
Elastic force, makes the first valve element to the direction movement for opening the first check valve, and the first valve element overcomes the elastic force of the first spring to open first
Check valve, makes the first valve element and the first air guide channel air-guiding gap occur;After first check valve is opened, the compressed air in cover tire
Entered by the first air inlet of the first check valve, between first valve element of compressed air Jing of cover tire and the first air guide channel between inducing QI
Gap is entered, and is entered in first inner tube of a tyre by the first gas outlet of the first air guide channel;When the pressure of first inner tube of a tyre reaches setting
After pressure, the compressed air in first inner tube of a tyre acts on the second drive disk of the second check valve, makes what the second valve element was subject to drive
Power puts on the elastic force of the second valve element more than second spring, the second valve element is moved to the direction for opening the second check valve, and second
Valve element overcomes the elastic force of second spring to open the second check valve, makes the second valve element and the second air guide channel air-guiding gap occur;The
After two check valves are 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 Jing the
Between two valve elements and the second air guide channel, air-guiding gap is entered, and is entered in second by the second gas outlet of the second air guide channel
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 is lost by sharp weapon pierce through
During pressure, the first closed check valve, first inner tube of a tyre maintain pressurising state, and first inner tube of a tyre is connect with cover tire by its first outer support post
Touch, first inner tube of a tyre is contacted with wheel rim 1 by its first inner support post, runflat supports motor vehicles by first inner tube of a tyre, it is to avoid or
Person reduces the generation of inclined tire accident;When cover tire, first inner tube of a tyre are by sharp weapon pierce through decompression, second inner tube of a tyre maintains pressurising state,
Second outer support post of second inner tube 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;The
Second inner support post of two inner tubes 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, explosion-proof
Tire supports motor vehicles by second inner tube of a tyre, it is to avoid or reduce the generation of inclined tire accident.
The invention has the beneficial effects 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, first driving the first valve element of dish driving 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
During sharp weapon pierce through decompression, the first closed check valve, first inner tube of a tyre maintain 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 are by sharp weapon pierce through decompression, second inner tube of a tyre maintains pressurising shape
