A novel internal structural tire for automatically inflating a small air bag, comprising a rubber tire (1), a small air bag layer (2), a hollow layer (3) and a metal hub (4), which are successively connected with one another from exterior to interior, wherein an inflation one-way valve (5) for automatically inflating the small air bag and preventing the back flow of gas in the small air bag is installed on a junction between each small air bag of the small air bag layer (2) and the hollow layer (3); the inflation one-way valve (5) is a rubber valve and comprises a rubber valve body (6) and a rubber valve plate (7), a central hole and an inflation hole (9) are arranged at the central part of the rubber valve body (6), the plane of the rubber valve body (6) and the plane of the rubber valve plate (7) are installed in parallel, and a central valve shaft (8) of the rubber valve plate (7) is installed in the central hole of the rubber valve body in a sleeving manner. The novel internal structural tire for automatically inflating the small air bag can supplement the air pressure in the small air bag at any time so as to balance the circumferential air pressure of the tire, thereby being stable to run, not at risk of piercing and puncturing, with good safety performance and long service life. |
