In order to explore the impact of rims with different widths on handling stability, the tire contour scanning test, static stiffness test and six-component force test, subjective evaluation test and objective test of real vehicle handling and stability were carried out. The static characteristics of tires with different widths of rims were analyzed and compared through static test and research on the bench. The actual dynamic performance of tires was analyzed and compared through subjective and objective test of real vehicle handling and stability. The change trend of vehicle handling stability was explored when the same tire was mounted on the wheel hub with different width. Bench test results show that the wider the wheel hub is mounted, the higher the vehicle handling stability is. The subjective and objective test results of the real vehicle also confirm this conclusion.

为探究不同宽度的轮辋对操纵稳定性的影响,开展轮胎轮廓扫描试验、静态刚度试验和六分力试验,实车操纵稳定性主观评价试验、客观试验,通过对台架的静态试验研究,分析比较了不同宽度轮辋的轮胎静力学特性,通过对比实车操纵稳定性主客观试验,分析比较了轮胎的实际动态表现,探究了相同轮胎在不同宽度的轮毂上安装时,整车操纵稳定性的变化趋势,台架试验结果表明,轮胎安装的轮毂越宽,车辆操纵稳定性越高,实车主客观试验结果也印证了这一点。

为探究不同宽度的轮辋对操纵稳定性的影响,开展轮胎轮廓扫描试验、静态刚度试验和六分力试验,实车操纵稳定性主观评价试验、客观试验,通过对台架的静态试验研究,分析比较了不同宽度轮辋的轮胎静力学特性,通过对比实车操纵稳定性主客观试验,分析比较了轮胎的实际动态表现,探究了相同轮胎在不同宽度的轮毂上安装时,整车操纵稳定性的变化趋势,台架试验结果表明,轮胎安装的轮毂越宽,车辆操纵稳定性越高,实车主客观试验结果也印证了这一点。

In order to explore the impact of rims with different widths on handling stability, the tire contour scanning test, static stiffness test and six-component force test, subjective evaluation test and objective test of real vehicle handling and stability were carried out. The static characteristics of tires with different widths of rims were analyzed and compared through static test and research on the bench. The actual dynamic performance of tires was analyzed and compared through subjective and objective test of real vehicle handling and stability. The change trend of vehicle handling stability was explored when the same tire was mounted on the wheel hub with different width. Bench test results show that the wider the wheel hub is mounted, the higher the vehicle handling stability is. The subjective and objective test results of the real vehicle also confirm this conclusion.

近年来,汽车工业的发展带动了国内轮毂产业的快速发展,轿车研发中采用的轮毂种类和规格、搭配的轮胎尺寸也越来越多。随着汽车消费者的年轻化,汽车的操纵稳定性日益受到重视。轮毂是车身重力传递到路面的重要部件,承受着转弯时的横向载荷、驱动力和制动力矩等,GB/T 2978—2014《轿车轮胎规格、尺寸、气压与负荷》[1]给出了轮胎可以适配的多种宽度的轮毂。不同宽度的轮毂装配相同的轮胎时,轮胎的宽度、接地面积、侧向刚度和纵向刚度将发生改变,这些改变将直接影响汽车的操纵稳定性。
本文选取某车型搭载的215/55 R17规格轮胎,分别安装在6.5J、7J、7.5J规格的轮毂上,基于轮胎单体台架试验、实车操纵稳定性主观评价试验及客观试验分析不同宽度的轮毂对操纵操稳性产生的影响。
单体台架试验包括轮廓扫描试验、静态刚度试验及六分力试验[2],使用的设备分别为轮胎扫描试验机、静态刚度测试机和六分力测试台,乘用车轮胎扫描试验机如图1所示。
轮廓扫描试验可以得到轮胎的接地面积,而轮胎接地面积直接影响轮胎的抓地性能,进而影响实车的操纵稳定性。
静态刚度试验及六分力试验可以输出径向刚度、横向刚度、纵向刚度、侧偏刚度、回正力矩等与实车操纵稳定性相关联的试验结果。
具体试验项目及条件如表1所示。
汽车操纵稳定性是车辆系统动力学的一个重要分支。车辆动力学是研究所有与车辆系统运动有关的学科[3]。汽车操纵稳定性的研究内容是汽车对驾驶员转向输入及外界干扰的响应[4],还有驾驶员在控制汽车时操纵感觉的难易轻便程度[5]。实车操纵稳定性客观试验项目选取GB/T 6323—2014《汽车操纵稳定性试验方法》[6]中的稳态回转试验及ISO 7401《道路车辆 横向瞬时响应试验方法 开路试验方法》中的频率扫描试验。实车操纵稳定性主观试验项目参考某企业的操纵稳定性主观评价试验标准。
稳态回转试验用以测定汽车的转向特性以及车身的侧倾特性,从而确定汽车的稳定性能。频率扫描试验用于评价实车的动态特性。主观评价主要评价车辆中心区响应、稳态性能、瞬态性能以及极限稳定性能,试验过程如图2所示。
不足转向度、侧倾梯度、最大侧向加速度、0.5 Hz时的横摆角度增益、横摆角速度对转向盘转角的滞后时间等试验结果是衡量实车操纵稳定性能的重要指标,具体试验项目如表2所示。
轮廓扫描试验结果如表3示。
试验结果表明,轮胎宽度与装配轮毂宽度正相关且影响显著,轮辋宽度增加1英寸(约合25.4 mm)时,轮胎宽度的变化差异超过5%。
台架静刚度试验结果如表4图3~图5所示。
试验结果表明,轮胎装配轮毂宽度与轮胎径向刚度、侧向刚度、纵向刚度整体呈正相关。其中轮毂宽度对侧向刚度的影响最大,对操纵稳定性影响较大。随轮毂宽度增加,侧向刚度增加,对侧倾的抑制能力增强,侧向运动的响应更快。
单体台架六分力试验结果如表5图6图7所示。
试验结果表明:
a. 轮毂宽度对载荷灵敏度-前轴(1°)影响最为显著,两者呈正相关,表明轮毂宽度增加,载荷转移灵敏度也随之提高;
b. 轮毂宽度对侧偏系数-前轴(1°)影响较大,呈正相关,表明在侧向加速度线性区,随轮毂宽度增加,轮胎侧偏刚度增大,影响不足转向度;
c. 轮毂宽度对载荷转移灵敏度-前轴(2°)影响较大,呈负相关,表明在非线性区,随轮毂宽度增加,车辆操控线性度增强。
单体台架试验结果表明,相同轮胎装配不同宽度轮辋的试验结果差异明显,随轮辋宽度的增大,影响操纵稳定性能的各参数均向操纵稳定性提升的方向变化。
稳态回转试验结果如表6所示。
试验结果表明,不同轮毂宽度对不足转向梯度影响较大,呈负相关。
频率扫描试验结果如表7所示。
实车主观评价试验结果如表8所示。
试验结果表明,不同轮毂宽度对横摆角速度增益及时间滞后影响较大,宽度越大,横摆角速度增益越大,时间滞后越短。
实车操纵稳定性试验结果表明,相同轮胎装配不同轮辋宽度的试验结果差异明显,其中不足转向梯度、侧倾梯度、0.5 Hz的横摆角速度增益、侧向加速度对转向盘转角滞后时间变化明显,且均趋向操纵稳定性提升的方向。
本文结合单体轮胎台架试验、实车操纵稳定性试验及实车主观评价,对轮胎装配不同宽度的轮辋进行试验,试验结果表明,不同轮辋宽度的轮胎对操纵稳定性能影响显著,相同轮胎装配的轮辋越宽,操纵稳定性越好。
