Abstract
The utility model discloses an air bag tire, which comprises a rim and an air bag without an inner tube, wherein the air bag without an inner tube is arranged on the rim, the air bag without an inner tube comprises a tire body and an annular air bag arranged on the inner wall of the tire body, the air bag and the tire body are coaxially arranged, and the air bag is filled with air in advance; the utility model improves the safety of the tire.
Description
Technical Field
The utility model relates to the technical field of tires, in particular to a pneumatic tire.
Background
Most of the existing automobile tire technologies are that the whole tire is inflated to reach a certain pressure so as to be capable of driving on the road. When the driving operation is improper, such as getting on a high platform, getting over a deep pit, pressing a stone at a high speed, etc., the tire side can deform due to impact, and the cord inside the tire side can be folded to break the cord or generate a gap, so that the tire bulge or even the tire burst is caused. The tire sidewall, which is the weakest part of the tire, is easily scratched by a sharp object, resulting in breakage and possibly causing a tire burst. If the automobile has a tire burst in the high-speed driving process, the wheels cannot provide supporting force for the automobile body after the tire burst, and the accident is caused because the sudden change of the gravity center of the automobile is easy to lose control.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the prior art, the utility model aims to provide a pneumatic tire, which improves the safety of the tire.
In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides an air bag tire, includes the rim and locates tubeless pneumatic tire on the rim, tubeless pneumatic tire includes the tire body and locates the tire body inner wall is annular gasbag, the gasbag with the coaxial setting of tire body, just the gasbag is full of gas in advance.
In a preferred embodiment, the number of the air cells is a pair, and the pair of air cells are respectively provided on both left and right sides of the inner wall of the tire main body.
As another preferred embodiment, the distance L between a pair of the air cells is larger than half of the section width SW of the tire body.
As another preferred embodiment, the bladder is provided with a first rubber sheet, a cord and a second rubber sheet in this order in a direction close to the inner wall of the tire body.
In another preferred embodiment, the air bag bonds the outer wall of the second rubber sheet and the inner wall of the tire body together through adhesive glue.
In another preferred embodiment, the rim is provided with an air valve. .
The utility model has the beneficial effects that:
the air bag pneumatic tire of the utility model is provided with annular air bags which are filled with air in advance on the inner walls of the left and right side walls. When the tire side is damaged and leaks air, the damaged air bag is quickly deformed and tightly attached to the inner wall of the tire side under the action of air pressure in the tire, so that the condition that the air pressure continuously leaks air is excessively changed is avoided, and the running stability of a vehicle is ensured. The air bag is formed by compounding a rubber sheet and a wire curtain, and is integrally bonded with the tire side wall, so that the strength of the tire side wall is increased. The tire burst is avoided when the tire side is impacted and scratched, and the driving safety of the vehicle is ensured. The tire assembling rim is a common rim, does not increase the tire assembling cost, and can be popularized.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Examples
As shown in fig. 1 and 3, the pneumatic tire of the present embodiment is a tubeless pneumatic tire. The tire comprises a tire body 1 and bladders 2, 4. The air bags 2 and 4 are annular and are respectively arranged on the left side and the right side inside the tire body 1. The airbags 2, 4 are pre-filled with air.
As shown in fig. 4, the airbags 2 and 4 are formed by compounding a first film a, a second film c and a cord b. The outer sides of the air bags 2 and 4 are bonded with the inner wall of the tire side of the tire body 1 through the bonding glue 7 by the air bags 2 and 4, and the tire is pressurized, heated and cured again, so that the air bags 2 and 4 are combined with the tire body 1 into a whole, namely a reinforcing layer is added on the tire side, and the strength of the tire side is enhanced. When the tire is impacted, more uniform deformation occurs, tire burst caused by cord breakage is avoided, and the risk of abrasion and tearing at the outer surface of the tire can be limited.
As shown in fig. 2, when the tire sidewall is punctured and leaks, the damaged bladder 2 is quickly deformed and tightly attached to the sidewall inner wall under the pressure of the air inside the tire, thereby preventing the tire from continuing to leak.
As shown in FIG. 1, the distance L between the airbags 2 and 4 is larger than the section width SW/2. The tire inner cavity 5 has enough space for inflation, so that the tire air pressure is prevented from changing too much after the tire side is punctured by the air bags 2 and 4 and the running stability of the vehicle is ensured. Meanwhile, the air bag 2 and the air bag 4 are prevented from being contacted with each other in the running process, and the service life of the tire is shortened due to friction.
As shown in fig. 1 to 3, the mounting rim 3 of the pneumatic tire of the present embodiment has a valve 6, which is a conventional rim. And a new rim is not required to be designed, a new tire mounting process is not used, the use cost is not increased, and the method can be popularized.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
