Detailed Description

The following description of the embodiments of the present invention is made with reference to the accompanying drawings 1-2:

as shown in fig. 1 and 2, an air bag structure type run-flat tire comprises a tire body 1 and a hub frame 2 installed at the center in the tire body 1, wherein the tire body 1 sequentially comprises a tread layer 11, an air bag structure layer 12, an inner layer 13, a sealant layer 14 and an inner tube 15 arranged in the sealant layer 14 from outside to inside,

the hub carrier 2 is provided with bolt holes 24. The wheel hub frame 2 is provided with a valve hole, the tire body 1 is provided with a valve 3 communicated to the inner part of the inner tire 15, and the valve 3 is installed in the valve hole of the wheel hub frame 2. An automatic pressure relief valve is arranged in the inflating valve 3.

The airbag structure layer 12 includes a plurality of airbag layers 22, and a plurality of bag-shaped spaces 221 are uniformly distributed in the airbag layers 22. The air bag structure layer 12 further comprises two air bag surface layers 21, a plurality of air bag layers 22 are arranged between the two air bag surface layers 21, and one surfaces of the two air bag surface layers 21 are respectively fixed on the tread layer 11 and the inner layer 13. A second sealant layer 23 is arranged between two adjacent airbag layers 22, and rubber partitions 222 are arranged between a plurality of bag-shaped spaces 221 of the airbag layers 22.

The first sealing adhesive layer 14 and the second sealing adhesive layer 23 are semi-solid jelly, and after sharp objects such as nails and blades penetrate through the first sealing adhesive layer 14 or the second sealing adhesive layer 23, sharp heads of the sharp objects can be effectively wrapped to prevent the sharp objects from further penetrating; meanwhile, after the sharp object is taken out, the first sealing adhesive layer 14 and the second sealing adhesive layer 23 can effectively plug the puncture hole, and safety risks are reduced.

The capsule-shaped space 221 has a regular hexahedron shape, an oval shape, or a regular spherical shape. The bag-shaped spaces 221 of two adjacent air bag layers 22 are arranged in a staggered mode, namely the bag-shaped space 221 of the upper air bag layer 22 corresponds to the rubber partition wall 222 of the adjacent lower air bag layer 22, and the rubber partition wall 222 of the upper air bag layer 22 corresponds to the bag-shaped space 221 of the adjacent lower air bag layer 22, so that the puncture-proof performance, the hardness, the elasticity and the like of the tire are kept as uniform as possible, and the explosion-proof performance is improved.
