Background

Tires were ground-rolling annular elastic rubber products fitted on various vehicles or machines, the earliest tires were made of wood or iron, which were seen both on the war chariot in ancient China and on the gentleman horse car abroad, and then, when exploring colombia from the new continent to the sea island in the west india isles in 1493 and 1496, a hard block of rubber played by local children was discovered, which surprised him, and later he brought this curious thing back to his country, and after several years, the rubber had been widely used.

In the process of vehicle running on the road surface, the road surface may have unevenness, so that the tire bears extrusion force higher than that in normal running, when the extrusion force borne by the tire reaches the critical value borne by the tire, the inflation tire of the tire can be extruded and burst, the support tire can rapidly collapse due to the loss of the support of the inflation tire, and finally the vehicle is out of control.

The working principle is as follows: when the inflatable tire 2 of the tire is subjected to the extrusion force reaching the critical value, the inflatable tire 2 explodes, in the process of the explosion of the inflatable tire 2, the impact force generates a strong extrusion effect on the annular air bag 3 due to the strong impact force of the explosion, so that the annular air bag 3 reaches the extrusion critical value, the annular air bag 3 is broken, the annular air bag 3 starts to leak air, the air pipe 7 is communicated with the annular air bag 3 and the circular air bag 8, namely, the air in the annular air bag 3 and the air in the circular air bag 8 are communicated, when the air in the annular air bag 3 leaks air, the internal air pressure is reduced, the air pressure in the circular air bag 8 is higher than that of the annular air bag 3, therefore, the air in the circular air bag 8 flows into the annular air bag 3 through the air pipe 7, the circular air bag 8 also starts to leak air, before the air in the circular air bag 8 leaks air, the baffle, and the bottom fixedly connected with montant 12 of baffle 9, the spacing spring 11 of montant 12 bottom consequently bears the extrusion force of circular gasbag, be in compression state, so after the air leakage of circular gasbag 8, spacing spring 11 with montant 12 jack-up until montant 12 leaves compression spring 13, after compression spring 13 has lost the restriction of montant 12, resume from original compression state, because the length that compression spring 13 compression deformation resumes is the twice of supporting shoe 5 and the distance of supporting child 1 inner wall, consequently compression spring 13 can promote connecting rod 10, and then promote the support of being connected with bracing piece 6 fast, make the outside cambered surface of supporting shoe 5 paste the inner wall of supporting child 1 tightly, play the effect of supporting and buffering to supporting child 1, prevent that supporting child 1 from collapsing.

When the inflatable tire 2 is exploded and is not destroyed in the annular airbag 3, the support tire 1 generates collapse phenomenon to generate pressure on the annular airbag 3, the annular spring is flattened to generate pressure on the telescopic rod 14, and the limit spring 15 in the outer rod of the telescopic rod 14 cannot support the huge pressure on the annular spring when the outer wheel collapses, so that the length of the telescopic rod 14 is reduced, the annular airbag 3 is flattened to further enable the conical block 16 to puncture the buffer, the annular airbag 3 leaks air rapidly, and the process is repeated.

In conclusion, the device for preventing the support tire 1 from collapsing after the inflation tire 2 of the common tire explodes is characterized in that the circular air bag 8 and the compression spring 13 are used in cooperation, the support rod 6 and the annular air bag 3 are used in combination, when the inflation tire 2 of the tire explodes due to the extrusion force reaching the critical value, the annular air bag 3 is broken due to the strong impact force of explosion in the explosion process of the inflation tire 2, so that the annular air bag 3 starts to leak air, the air pipe 7 penetrates through the annular air bag 3 and the circular air bag 8, so that the circular air bag 8 also starts to leak air, the baffle 9 at the bottom of the circular air bag 8 is extruded by the circular air bag 8 due to the extrusion effect of the rim 4 plate before the circular air bag 8 leaks air, the bottom of the baffle 9 is fixedly connected with the vertical rod 12, and the limit spring 11 at the bottom of the vertical rod 12 bears the extrusion, be in the compression state, so after the gas leakage of circular gasbag 8, spacing spring 11 with montant 12 jack-up until montant 12 leaves compression spring 13, after compression spring 13 has lost montant 12's restriction, resume from original compression state, because the length that compression spring 13 compression deformation resumes is the supporting shoe 5 and the twice of supporting child 1 inner wall distance, consequently compression spring 13 can promote connecting rod 10, and then promote the support of being connected with bracing piece 6 fast, make the outside cambered surface of supporting shoe 5 paste the inner wall of supporting child 1 tightly, play the effect of supporting and buffering to supporting child 1, prevent that supporting child 1 from collapsing, thereby reached and prevented the effect that supporting child 1 collapses after inflatable tyre 2 explodes.

Through the cooperation use of limit force spring 15 and telescopic link 14, combine the supplementary use of conical block 16 and annular gasbag 3, when not destroying annular gasbag 3 after inflating child 2 explodes, support child 1 the phenomenon of collapsing will appear, produce pressure to annular gasbag 3, annular spring is flattened, and then produce pressure to telescopic link 14, because the huge pressure to annular spring when the outer wheel of unable support of limit force spring 15 in the telescopic link 14 outer pole collapses, consequently, the length of telescopic link 14 reduces, lead to annular gasbag 3 to flatten and then make conical block 16 puncture with the buffering, annular gasbag 3 leaks gas rapidly, thereby reached and prevented that annular gasbag 3 from not being destroyed the gas leakage by inflating child 2 explosion, can't prevent the effect that supports child 1 and collapse.
