本発明は空気入り安全タイヤに関し、さらに詳しくは、
特にサイドウオール部に補強ゴム層を配置した空気入り
安全タイヤの改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pneumatic safety tire, and more particularly:
In particular, the present invention relates to improvements in pneumatic safety tires in which a reinforcing rubber layer is disposed in the sidewall portion.
一般に乗用車用タイヤはパンク等によりタイヤ空気圧が

わみが大きくなり、タイヤは完全につぶれタイヤ内面で
の摩擦、発熱による内面の破損と、リムフランジによる
タイヤサイドウオール部の破損を生じる。このためパン
ク状態での走行は直ぐにタイヤ破損を引き起こし走行不
能となってしまう。Generally, when a passenger car tire tries to run with zero air pressure due to a puncture, etc., the sidewall section becomes deflected, causing the tire to collapse completely, causing damage to the inner surface due to friction and heat generation on the inner surface of the tire, and damage to the rim flange. This will cause damage to the tire sidewall. For this reason, driving with a flat tire will quickly damage the tire, making it impossible to drive.
そこで従来この対策として、補強部材をタイヤ内面、イ
ンナーライナとカーカス層間、カーカス層間、あるいは
カーカス層と外皮ゴム間等に配置してタイヤのサイドウ
オール部を補強強化し、パンク時すなわちランフカット
走行時におけるサイドウオール部のたわみを少なくする
手段が種々提案されている。Conventionally, as a countermeasure against this, reinforcing members are placed on the inner surface of the tire, between the inner liner and the carcass layer, between the carcass layers, or between the carcass layer and the outer skin rubber to strengthen and strengthen the sidewall of the tire. Various means have been proposed for reducing the deflection of the sidewall portion.
しかしながら、この手段はいずれもビード部とサイドウ
オール部あるいはショルダ一部にがけて別々の補強部材
により補強しているため、補強効率が悪く満足のいく耐
久性を得るためには、多くの補強部材を必要とし、この
結果、重量増加を伴うばかりでなく製造工程も複雑とな
りコストアップをまねいている。However, in all of these methods, separate reinforcing members are used to reinforce the bead, sidewall, or part of the shoulder, which results in poor reinforcing efficiency and requires the use of many reinforcing members in order to obtain satisfactory durability. As a result, not only is the weight increased, but the manufacturing process is also complicated, leading to increased costs.
また従来のこの種安全タイヤは、ランフラット走行時に
おけるサイドウオール部屈曲によるタイヤ各部への引張
応力及び圧縮応力を、別々の補強部材でそれぞれ分担せ
しめているため、非常に効率が悪く満足のいく耐久性が
得られず。Furthermore, in conventional safety tires of this kind, the tensile stress and compressive stress applied to each part of the tire due to the bending of the sidewall part during run-flat driving are shared by separate reinforcing members, which is extremely inefficient and unsatisfactory. Durability is not achieved.
さらにカーカス層の巻き上げ側端部がランフラット走行
時における屈曲部にある場合には、ランフラット走行中
のサイドウオール部の屈曲により、前記巻き上げ側端部
に応力が集中し、クランク等が発生し、やはり耐久性を
低下せしめる等問題があるのが現状である。Furthermore, if the rolled-up side end of the carcass layer is at the bending part during run-flat running, stress will be concentrated on the rolled-up side end due to the bending of the sidewall part during run-flat running, and cranks etc. will occur. However, the current situation is that there are still problems such as decreased durability.
本発明は上述した問題点を解消するため、検討の結果導

全タイヤの欠点をことごとく改善し得るようにした優れ
た空気入り安全タイヤを提供することにある。Therefore, an object of the present invention is to provide a pneumatic safety tire in which a reinforcing member, that is, a reinforcing rubber layer is arranged especially in the sidewall part, by improving the arrangement position of the reinforcing rubber layer and the end position on the winding side of the carcass layer. An object of the present invention is to provide an excellent pneumatic safety tire that can completely improve the drawbacks of conventional safety tires of this type.

ヘル）１１１７の端部７ａの下面とカーカス層５の上面
によって挾持されしっがりと固定されている。To further explain this structure, in this embodiment, one carcass layer 5 is arranged, and two belt layers 7 are arranged outside the carcass layer 5 in the tread portion B. Therefore, since the carcass layer 5 is one layer in this embodiment, the reinforcing rubber layer 6 disposed radially outward and adjacent to the pair of bead cores 8 is rolled up around the carcass layer 5 and the bead cores. It is sandwiched between the carcass layer 5 and the rolled-up side 5a. In this embodiment, the end 6a on the tread side of the reinforcing rubber layer B and the end 5a on the winding side 5a are the end 7 on the side of the shoulder part 4 of the two belt layers 7 as shown in the figure.
The end portions 5a and 6a are sandwiched and firmly fixed by the lower surface of the end portion 7a of the shell 1117 and the upper surface of the carcass layer 5.

Although one layer is arranged, two or more layers may be arranged. In this case, it is preferable that the ends 5a of all the carcass layers 50 on the winding side 5a are rolled up to the bottom of the belt layer 7. However, as described above, if at least the end portion 5a of the outermost carcass layer 5 on the rolled-up side 5a is rolled up to the lower part of the belt layer 7, the effects described below can be sufficiently obtained.

屈曲を受はカーカス層５側で引張り応力を受けている。Since the pneumatic safety tire E according to the present invention is constructed as described above, during run-flat running, as shown in FIG. 2, an example of this is shown in FIG. The sidewall portion 2° and the shoulder portion 4 are each subjected to large bending.More specifically, in the bead portion 1, the rim 7
It is bent around the lunge 9 and receives tensile stress on the carcass layer 5 side, the sidewall part 2 is bent around the inner surface of the tire and receives tensile stress on the rolled-up side 5a of the carcass layer 5, and the shoulder part 4 receives tensile stress. The bending centering around the tire outer surface is subjected to tensile stress on the carcass layer 5 side.
また、それぞれの部分での圧縮力に対しては補強ゴム層
６で受けており何れの方向への屈曲に対しても引張りに

できる。Further, as described above, the reinforcing rubber layer is sandwiched between at least the outermost carcass layer and the side of the carcass layer rolled up around the bead core, and the reinforcing rubber layer is sandwiched between the reinforcing rubber layer and the side of the carcass layer rolled up around the bead core. Since the end portion reaches at least the bottom of the belt layer, the compressive stress and tensile stress caused by bending in the sidewall portion etc. during run-flat running are effectively absorbed by the compression-resistant reinforcing rubber layer and the tensile-resistant carcass layer. It is possible to have them share the same. As a result, the durability necessary for run-flat running can be obtained with a relatively small amount of reinforcing rubber layer, and the weight of the tire can be reduced, thereby reducing costs.
