Example 9

As shown in fig. 53 to 62, on the basis of the above embodiments 1 to 7, in the present embodiment, the inner surface of the outer tire 20 is provided with the inflatable ring 31, the inflatable ring 31 is provided with the second inflatable cavity 313, and the inflatable ring 31 is provided with the variable (double-set) spherical valve plug valve, which is configured to be tightly attached to the diameter of the inner surface of the outer tire 20 by the outer surface of the diameter of the inflatable ring 31. The second valve 32 that the gas filled ring 31 set up is spherical air pressure regulating valve, and this valve includes body 321, globe valve 322 and spring 323, body 321 is equipped with inlet port 324, mounting groove 325 and intake duct 326 along the central axis, and the linking department of mounting groove 325 and intake duct 326 is the horn mouth, and in mounting groove 325 was arranged in to spring 323 one end, the other end was fixed with globe valve 322, and globe valve 322 just can be reciprocating motion in arranging the installation in.

The elastic coefficient K of the spring 323 and the pressure value P in the first inflation cavity 21 are in a linear relationship, when P is a certain value, the elastic force of the spring 323 is balanced with the pressure, the inflation ring 31 does not inflate, and when P is lower than a critical value, the inflation ring 31 keeps the pressure unchanged.

When the tire is mounted on the wheel hub 10 and the inflation state of the tire reaches a certain air pressure, the air pressure pushes the ball valve 322 through the air inlet 324 to act on the spring 323 to move, the ball valve 322 leaves the bell mouth to allow the air inlet 326 to be completely opened, the air is filled into the inflating ring 31, and when the air pressure of the first inflating cavity 21 reaches a preset air pressure value, the inflating ring 31 is inflated.

Specifically, the variable (double-arranged) spherical air pressure regulating valve can automatically regulate and coordinate the air pressure change of the outer tyre 20, when the air pressure of the outer tyre 20 reaches the standard air pressure value, the currently common air pressure value is 2.4bar, in order to keep the air pressure in the inflatable ring 31 consistent with the air pressure of the outer tyre 20, the variable (double-set) spherical air pressure regulating valve opens the air inlet, when the air pressure of the outer tire 20 changes in a small range, the air pressure of the inflatable ring 31 keeps consistent with the air pressure of the outer tire 20, when the air pressure of the outer tire 20 is lower than the normal set air pressure value, for example, when the air pressure of the outer tire 20 is 2.0-0bar, the ball valve 322 will flow in the opposite direction of the air pressure of the inflatable ring 31, when the force of the spring 323 is larger than the air pressure of the outer tire 20, the ball valve 322 is automatically and rapidly pushed to return to the bell mouth, the air inlet 324 is closed, the air pressure in the inflatable ring 31 is kept unchanged, and the inflatable ring 31 supports the outer tire 20 to continue running at low speed.

Example 10

In the embodiment, the outer tire 20 and the inner tire 30 are sequentially installed, and the inflatable ring 31 of the inner tire is pre-held in a 8-shaped state and is pre-installed on the inner surface of the outer tire 20, so that the problem that the integral inflatable ring 31 is difficult to install is solved ingeniously, the inflatable ring 31 is favorable for quick installation and is more convenient to disassemble and repair, after the inflatable ring 31 is installed on the left side surface or the right side surface of the upper part of the inner surface of the outer tire 20, the automobile tire has increased safe running performance, the inflatable ring 31 can play a role in supporting the outer tire 20 to continue running in a tire burst and air leakage state of the outer tire 20, and therefore, the automobile can be ensured to continue to run safely when a tire burst occurs in the high-speed.
