摘要
分析了影响轿车子午线轮胎滚动阻力的因素。轮胎的结构、胎体及带束层帘线材料、胎面胶种类以及轮胎气压和负荷都对轿车子午线轮胎滚动阻力有一定的影响 ,具体体现在由于轮胎变形产生的滞后损失和材料本身的滞后损失。通过减小轮胎断面高宽比、增大轮辋直径、采用高模量材料作带束层、使用S
The effective factors on the rolling resistance of radial passenger car tire are analysed.It is shown by the hysteresis losses resulted from the tire deformation and the material itself that the tire structure,the reinforcing materials in carcass ply and belt,the tread compound,as well as the inflation pressure and load of tire are the effective factors on the rolling resistance of radial passenger car tire.The rolling resistance of the tire can be reduced by decreasing the aspect ratio of tire,increasing the diameter of rim,using the materials with high modulus in belt and the materials with low hysteresis,such as S SBR and silica,in tread compound.
