The invention relates to an engineering machinery radial tire pattern groove structure and a tire, the pattern groove structure comprises a pattern groove, the pattern groove comprises a pattern groove wall, an inclination angle alpha is formed between the pattern groove wall and the depth of the pattern groove, and the pattern groove wall is connected with the bottom of the pattern groove through an arc curved surface. The arc-shaped curved surface comprises a first arc-shaped curved surface and a second arc-shaped curved surface which are connected with each other, the first arc-shaped curved surface is connected with the bottom of the pattern groove, and the second arc-shaped curved surface is connected with the wall of the pattern groove. The first arc-shaped curved surface is tangent to the bottom of the pattern groove, and the second arc-shaped curved surface is tangent to the wall of the pattern groove. By designing the angle and the position of the pattern groove, the stress concentration phenomenon in the direction of the bottom of the pattern groove can be effectively reduced, the problem of overlarge transition between the pattern groove wall and a section of arc is effectively improved, the risk of cracking at the bottom of the pattern groove and stone clamping due to poor self-cleaning performance is delayed, the service life of the tire is prolonged, and the comprehensive performance of the tire is improved.

    本发明涉及一种工程机械子午线轮胎花纹沟槽结构及轮胎,其中,花纹沟槽结构包括:花纹沟槽,花纹沟槽包括花纹沟壁,花纹沟壁与花纹沟深度形成倾角α,花纹沟壁与花纹沟槽底部通过弧形曲面连接。弧形曲面包括:第一弧形曲面和第二弧形曲面,第一弧形曲面和第二弧形曲面连接,第一弧形曲面与花纹沟槽底部连接,第二弧形曲面与花纹沟壁连接。第一弧形曲面与花纹沟槽底部相切,第二弧形曲面与花纹沟壁相切。本发明通过对花纹沟槽角度和位置的设计可以有效降低花纹沟槽底部方向应力集中现象,有效改善花纹沟壁与一段弧之间过度过大问题,延缓花纹沟底裂口和由于自洁性差夹石子的风险,提升轮胎使用寿命,实现轮胎综合性能的提升。
