半钢子午线轮胎的侧偏特性研究

Research on Cornering Properties of Steel-belt Radial Tire

研究带束层角度和三角胶高度对半钢子午线轮胎侧偏特性的影响。结果表明:带束层角度越小,轮胎的侧偏力、最大侧偏力和侧偏刚度越大,回正力矩和回正刚度越小;三角胶高度越大,轮胎的侧偏力、侧偏刚度和回正刚度越大,回正力矩变化不大。因此轮胎的带束层角度越小、三角胶高度越大,车辆的操纵稳定性越好。

The influence of belt angle and apex height on the cornering properties of steel-belt radial tires was studied.The results showed that the smaller the belt angle was,the greater the tire’s cornering force,maximum cornering force and cornering stiffness were,and the smaller the aligning torque and aligning stiffness were.The greater the apex height was,the greater the tire’s cornering force,cornering stiffness and aligning stiffness were,but the aligning torque changed little with the apex height.Therefore,the steering stability of the vehicle could be improved by reducing the belt angle and increasing the apex height.
