Abstract

PROBLEM TO BE SOLVED: To easily and surely prevent an occurrence of puncture caused by a contact between the wall surfaces of tubes. SOLUTION: An outer partition wall 5o and an inner partition wall 5i are built (like a bridge) inside the peripheral wall 4 of a tube 2, which is accommodated in a tire 1, thereby forming an outer sealant chamber 7o and an inner sealant chamber 7i, which are filled with a sealant, and an air chamber 3 surrounded by the chambers 7o, 7i. When the tire 1 runs on an obstacle so that both the tire 1 and the tube 2 are held/pressed by a flange part 12 of a rim (R) and the obstacle, the shock is relieved by the outer partition wall 5o, the inner partition wall 5i, and the sealant 8, thereby preventing the damage of the tube 2. If the tube 2 should be damaged, since the damaged is mended by the sealant 8, there will be no air-leakage from the air chamber 3.

[0003] When a radial load is applied to a wheel on which a tire with a tube is mounted, the tire and the tube are deformed by the load. In particular, the tire may ride on a hard obstacle such as a rock during off-road driving. When the vehicle jumps and touches the ground, the tube is strongly pinched between the greatly deformed tire and the metal rim, and the rim striking phenomenon in which the inner wall surfaces of the tubes come into contact with each other. May occur. When the inner wall surfaces of the tubes come into contact with each other due to the rimping phenomenon, a hole may be opened at that portion, so-called shock puncture may occur.

Parts 12, 12 are provided. The base of the air valve 6 that fills the air chamber 3 formed inside the tube 2 with air is supported by a raw rubber air valve mounting portion 16 that is joined so as to penetrate the inner peripheral wall 4i and the inner partition wall 5i. .

Thus, the outer sealant chamber 7o of the tube 2
In addition, since the inner sealant chamber 7i is held in a shape along the inner surface of the tire 1 by the air pressure of the air chamber 3, centrifugal force due to rotation of the wheel acts on the sealant 8 filled in both sealant chambers 7o and 7i. Even so, it is possible to prevent the sealing agent 8 from being biased toward the outer peripheral side of the tube 2. Therefore, even if the tube 2 is punctured by a nail or the like, the sealing agent 8 immediately fills and repairs the puncture, thereby delaying the leakage of air from the air chamber 3. Moreover, since the outer sealant chamber 7o and the inner sealant chamber 7i cover not only the outer peripheral side but also the inner peripheral side of the tube 2, even if any part of the tube 2 is punctured,
The puncture can be repaired with the sealant 8. Also,
Since the sealant 8 is held in both sealant chambers 7o and 7i and does not flow out to the air chamber 3, the air valve 6 and the pressure gauge applied thereto are not clogged.

As shown in FIG. 3, the tubed tire T
When the vehicle rides on the obstacle 20 on the road surface and a shocking load is applied, the load compresses a part of the tire 1 and the tube 2 in the radial direction. At this time, the flanges 12 and 12 of the rim R projecting outward in the radial direction and the obstacle 20
, The tire 1 and the tube 2 are pinched, and the inner wall surfaces of the tube 2 contact each other. However, the tube 2 pinched by the tire 1 has an outer peripheral wall 4o,
Since the outer partition wall 5o, the inner partition wall 5i, and the inner peripheral wall 4i have a sufficient thickness and elasticity in a four-layer state, damage to the tube 2 due to rim striking can be effectively prevented.

In addition, since the outer sealant chamber 7o and the inner sealant chamber 7i are filled with the sealant 8, the two sealant chambers 7o and 7i are compressed near the ground contact portion of the tire 1, and the sealant 8 is removed. Due to the shock absorbing effect when moving above the tube 2, damage to the tube 2 due to rim striking can be more effectively prevented. Further, even if the tube 2 is damaged by rim striking, the damage is repaired by the sealing agent 8 filled in the outer sealing agent chamber 7o or the inner sealing agent chamber 7i.

As described above, according to the first aspect of the present invention, the outer sealant chamber and the inner sealant chamber filled with the sealant are defined so as to cover the entire circumference of the tube. Even if any part of the tube receives a puncture, the puncture can be repaired with a sealant to prevent air leakage. Also, even if a large load acts on the tire and the tube is strongly pinched between the tire and the rim, the tube has four layers of the outer peripheral wall, the outer partition, the inner partition, and the inner peripheral wall, and has a sufficient thickness. And elasticity, it is possible to effectively prevent damage to the tube due to rim striking. In addition, even if the tube is damaged by rim striking, the damage can be repaired with a sealant. Further, since the tube has a simple structure in which the outer sealant chamber and the inner sealant chamber are formed and the sealant is simply filled, no increase in weight or increase in manufacturing cost is caused.
