Problems solved by technology

[0003] Nowadays, tubeless pneumatic tires have been widely used in small passenger vehicles, but when the tires are punctured, under-inflated or without air pressure, existing conventional tubeless tires (such as figure 1 As shown) there are still problems such as being unable to continue driving or the tire sidewall is seriously deformed, which causes the sidewall cord to be damaged and scrapped.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 2 Shown is a sidewall recessed run-flat tire, including a rim 5 and a tire sleeved on the rim 5;

[0022] Wherein, the cross-sectional structure of the tire includes a crown area 1 at the top of the tire, a sidewall area 3 on both sides of the tire, a shoulder area 2 where both sides of the crown area 1 transition to the sidewall area 3, and a bottom area of ​​the sidewall area 3. The bead area 4, and the bead area 4 is installed on the rim 5; the sidewall area 3 adopts an overall concave design, and the top of the sidewall area 3 is connected to the shoulder area 2 and the bottom of the sidewall area 3 is connected to the rim 5 The positions are all in the form of raised structures 13 .

[0023] In this embodiment, the outer tire includes an inner liner airtight layer 6, a carcass ply 7, a buffer belt layer 8 and a tread rubber layer 9 arrange...

Abstract

The invention discloses a tire sidewall concave type run flat tire which comprises a rim and an outer tire body connected to the rim in a sleeving mode. The outer tire body comprises a tire crown area on the top of the outer tire body, tire sidewall areas on the two sides of the outer tire body, tire shoulder areas for transition from the tire crown area to the tire sidewall areas, and tire bead areas at the bottoms of the tire sidewall areas, and the tire bead areas are installed on the rim. The tire sidewall areas are of integrally concave design. The junction portions of the tops of the tire sidewall areas and the tire shoulder areas and the junction portions of the bottoms of the tire sidewall areas and the rim are each of a protruding structure. By the adoption of the structure that the tire sidewalls are integrally concave, and the upper end and the lower end are thickened and protrude, the vertical supporting performance of the tire sidewalls is effectively improved, the run flat tire can still travel normally for 3000-5000 meters in case of puncture, air pressure deficiency or air pressure absence, meanwhile, the possibility of damage to tire cords of the tire sidewalls is reduced, safety and stability of the tire are greatly improved, and the service life of the tire is greatly prolonged.

Description

technical field [0001] The invention relates to an explosion-proof tire, in particular to a sidewall recessed type explosion-proof tire. Background technique [0002] Compared with tires with inner tubes, the advantages of tubeless tires, that is, tubeless tires, are obvious. First, tubeless tires are much thicker than traditional inner tube tires. Once punctured, the gas will not be completely released in an instant like ordinary tires, and will last for a certain period of time without causing the steering wheel to lose control instantly, ensuring the safety of high-speed driving; When the inner tire is installed, the change is small when the vehicle is moving at high speed, and it can maintain good driving stability and small friction, which is obviously conducive to the absorption of shock and shock and the improvement of vehicle speed. The comfort and stability are better than those of ordinary tires. It is much better; the third is that the structure of the tubeless t...
