The invention provides a method for improving a tire sidewall mouth shape of tire cornering rigidity, and belongs to the technical field of tires. According to the sidewall mouth shape method for improving the cornering rigidity of the tire, the inner side of a sidewall is coated with sidewall rubber, then the sidewall rubber is bonded to rim rubber on a rim to form a rim rubber and sidewall rubber overlapping position, and the rim rubber and sidewall rubber overlapping position is designed in a tooth-shaped meshing mode. Proportional constraint is carried out on the length size of each part of the sidewall, a tooth-shaped meshing design is adopted in the overlapping position of sidewall rubber and rim rubber, an India transition area is optimized, different proportional length parameters can be selected according to vehicle performance positioning, and then the performance of the whole vehicle is achieved. The shapes and sizes of rubber materials at different positions of a tire sidewall are optimally designed according to a certain proportion, and a novel tooth-shaped meshing design is adopted at the overlapped part of sidewall rubber and rim rubber. And the tire cornering rigidity can be improved while the tire comfort is guaranteed, the problems of insufficient lateral support and the like during vehicle turning are effectively solved, and the control performance is improved.

    本申请提供了一种提高轮胎侧偏刚度的胎侧口型的方法,属于轮胎技术领域。该提高轮胎侧偏刚度的胎侧口型的方法,在胎侧的里侧涂上胎侧胶,然后将胎侧胶粘合在轮缘上轮缘胶上形成轮缘胶和胎侧胶重合位置,且轮缘胶和胎侧胶重合位置处为齿状咬合设计。对胎侧各部位长度尺寸进行比例约束,以及胎侧胶和轮缘胶重合位置采用齿状咬合设计,优化印度过渡区域,可根据车辆性能定位选择不同比例长度参数,进而实现整车性能达成。通过对轮胎胎侧不同位置的胶料形状尺寸按照一定比例进行优化设计,胎侧胶和轮缘胶重合部位采用新型齿状咬合设计。保证轮胎舒适性的同时可以提升轮胎侧偏刚度,有效改善车辆转弯时侧向支撑不足等问题,提升操控性能。
