〔産業上の利用分野〕
本発明は、トレッド溝の石噛みを防止した空気入リタイ
ヤに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pneumatic tire that prevents stone from building up in the tread grooves.
ラジアルタイヤのトレッド部にスチールコードよりなる
ベルト層を設けると、タイヤのトレッドの合成が大きく
なり、動きが抑制されるので、石噛みが発生しやすくな
り、一端噛んだ石は放出されに、くい。従って、トレッ
ド溝に噛んだ石により、トレッド溝の溝底が損傷し、ベ
ルト層のスチールコードを破損する虞がある。When a belt layer made of steel cord is provided on the tread of a radial tire, the composition of the tire tread becomes larger and movement is suppressed, making it easier for stones to get stuck. . Therefore, the stones stuck in the tread grooves may damage the bottom of the tread grooves and damage the steel cords of the belt layer.
タイヤのトレッド溝の石噛みを防止する方法として、特
開昭５０−９８００２号にタイヤのトレッド溝の側壁部
に２段以上の段を設けた段付き溝を有するタイヤが提案
されている。As a method for preventing stone build-up in the tread groove of a tire, Japanese Patent Laid-Open No. 50-98002 proposes a tire having a stepped groove in which two or more steps are provided on the side wall of the tread groove of the tire.
又、特願昭６０−７８８５号（特開昭６１−１６６７０
８号）において溝の片側又は両側の側面から溝の中央部
に向かって張り出す段部を設け、その段部にサイプを設
けることを開示した。Also, Japanese Patent Application No. 16670/1983
No. 8) discloses providing a step portion projecting from one or both side surfaces of the groove toward the center of the groove, and providing a sipe on the step portion.
上記の従来のタイヤは石噛みを防止する効果はあるが、
段部の設置により、段部より下の溝幅が非常に狭くなり
、タイヤが摩耗してくると溝の断面積が著しく狭くなり
、濡れ路面走行時の溝の排水効果が低下し、濡れ路面で
のトラクション性能を低下させる。The conventional tires mentioned above have the effect of preventing stone bite, but
Due to the installation of the step, the width of the groove below the step becomes extremely narrow, and as the tire wears out, the cross-sectional area of the groove becomes significantly narrower, reducing the drainage effect of the groove when driving on a wet road. traction performance is reduced.
石噛みを防止するためには、溝の浅い位置に大きく張り
出す段部を設ける方が効果が大きいが、溝の排水効果を
阻害しないために、段部の高さと幅を充分大きくとるこ
とができない。In order to prevent stone build-up, it is more effective to provide a large step in the shallow part of the groove, but it is important to make the height and width of the step sufficiently large so as not to impede the drainage effect of the groove. Can not.
充分な石噛み防止効果をだすために段部の幅と高さを大
きくすると段部まで摩耗する前でも排水効果が低下する
。このためトラクション性能をあまり低下させないよう
に、段部の張出し幅及び段部の高さをあまり大きくする
ことはできなかった。If the width and height of the stepped portion are increased in order to achieve a sufficient stone encroachment prevention effect, the drainage effect will decrease even before the stepped portion is worn down. For this reason, it has not been possible to increase the overhanging width of the stepped portion and the height of the stepped portion so as not to significantly reduce the traction performance.
また段部により、トレッド溝の溝底の幅が狭められると
、タイヤ接地時の屈曲運動による応力が溝底の特定箇所
に集中し、クランクの発生を助長する虞がある。Furthermore, if the width of the groove bottom of the tread groove is narrowed by the stepped portion, stress caused by the bending motion when the tire contacts the ground is concentrated at a specific location on the groove bottom, which may encourage the occurrence of cranking.
従って本発明はトレッド溝に段部を設けても溝の排水効
果が阻害されず、濡れ路面でのトラクション性能が低下
することがなく、大きな石噛み防止効果を発揮するタイ
ヤを提供することを目的とする。Therefore, an object of the present invention is to provide a tire that does not impede the drainage effect of the grooves even when a stepped portion is provided in the tread grooves, does not reduce the traction performance on wet road surfaces, and exhibits the effect of preventing large stone bite. shall be.
上記目的を達成すべく、本発明者らは鋭意研究を重ねた
結果、トレッド溝の側壁から棚段をオーバーハングする
ように張出し、棚段より下側の棚段側壁面を斜め下方に
面して設け、棚段より下方でトレッド溝の幅が拡がるよ
うにすることにより、トレッド溝の断面積を大きくし、
トレッド溝の排水効果を高めることができ、またこれに
よりトレッド溝の底が拡がり、溝底のクランク発生を防
止しうろことを見いだし、本発明を完成するに至った。In order to achieve the above object, the inventors of the present invention have conducted intensive research, and as a result, the shelves are overhanging from the side walls of the tread grooves, and the side walls of the shelves below the shelves face diagonally downward. The cross-sectional area of the tread groove is increased by increasing the width of the tread groove below the shelf.
The inventors of the present invention have discovered that the drainage effect of the tread groove can be enhanced, and that the bottom of the tread groove is thereby widened to prevent cranking at the bottom of the groove, thereby completing the present invention.

とする石噛みを防止した空気入りタイヤを要旨とする。That is, the present invention provides a pneumatic tire having tread grooves arranged in a substantially circumferential direction in the tread portion of the tire. The side wall surface of the tread on the lower side of the tread is inclined with respect to a perpendicular line on the tread surface, and at a position deeper than the upper surface of the tread, the tread groove is inclined in a direction in which the width of the groove increases as the depth increases. This article focuses on a pneumatic tire that prevents stone entrapment and is characterized by:

The side wall (2) of the tread groove, which has a zigzag shape or other shape and may extend generally along the circumferential direction of the tire as a whole.
The tread grooves (
A shelf (3) is provided so as to overhang from 11.

（１）の幅が極端に狭められることがない。The shelf (3) may be provided only on one side wall (2) of the tread groove (1), or may be provided on both side walls (2).
In addition, one side wall (2) may have one shelf (3), or multiple shelves may be completely disposed.If the shelves (3) are provided on both side walls (2), they should be mutually spaced. It is preferable that the upper surfaces (6) of the shelves (3) facing each other are not at the same height, but have a difference in height.

By changing it periodically along the tread groove (11), the reinforcing effect by the step (3) on the side wall (2) of the tread groove (11) can be equalized, and the wear of the lips or blocks on both sides of the tread groove (11) can be equalized. This can prevent unevenness.In this case, the upper surfaces of the shelves on both sides (6
) is preferably alternated periodically.

。According to the pneumatic tire that prevents stone biting of the present invention, the cross-sectional area of the tread 4 (11) is less narrowed by the terraces (3), and the groove width is expanded at the bottom of the tread groove (1). This makes it possible to maintain a high drainage effect of the tread groove +11 even if a large shelf (3) is provided.
