The invention discloses a tool tire for mute cotton testing and a testing method, and belongs to the technical field of tire mute cotton testing. According to the technical scheme adopted by the invention, the inner cavity structure is composed of a tread and a sidewall which are located on the outer surface, and a cap ply, a belted layer, a lining layer and a tire bead which are located inside, the section curve of the tread in the axial direction is in an arc shape which is formed by sinking tire shoulders on the two sides towards the center of the tread, and during testing, mute cotton is attached to the arc-shaped sunken position. According to the invention, the concave part is arranged on the tread of the tire, so that the mute cotton is adhered to the tread of the tire during testing, an isolating agent on the inner wall of the tire does not need to be cleaned, the tire needs to be detached from a rim and then the mute cotton is applied when a next group of mute cotton is tested, and the working efficiency is improved; and through the design of the diameter, the material and the width of the sunken part, the adhesive force between the mute cotton and the sunken part is improved, so that the adhesive force of the mute cotton on the tread is slightly different from that of the mute cotton in a tire lining, and the mute cotton cannot fall off from the tread of the tire.

    本发明一种用于静音绵测试的工装轮胎及测试方法,属于轮胎静音绵测试技术领域。本发明采用的技术方案具体为包括位于外表面的胎面和胎侧以及内部的冠带层、带束层、内衬层、胎圈共同组成的内空腔结构,所述胎面在轴向方向上的截面曲线呈两侧胎肩处向胎面中心处凹陷的弧形,测试时,所述静音绵贴于弧形凹陷处。通过在轮胎胎面上设置的凹陷处,使静音绵在测试时,粘贴在轮胎的胎面上,无需清洁轮胎内壁的隔离剂以及在测试下一组静音绵时,需要将轮胎从轮辋上拆卸下来再敷贴静音绵,提高了工作效率;通过凹陷处直径、材质、宽度的设计,提高了静音绵与凹陷处的粘贴力,使静音绵在胎面的粘贴力与胎里的粘贴力相差不大,不会从轮胎胎面脱落。
