双转向轴车辆车轮定位检测探讨 甘晓珍东风商用车有限公司技术中心 王征东风商用车有限公司技术中心 【摘要】车辆的车轮定位对车辆转向操控性能至关重要，与车辆转向轴轮胎磨损也密切相关。车轮定位 主要有主销内倾角、后倾角，车轮外倾角及前束。双转向轴车辆车轮定位除了上述参数之外，还有第二转 向轴轮胎与第一转向轴轮胎的平行度。主销内倾角、后倾角，主要影响车辆转向操控性能：车轮前束、平 行度则影响轮胎磨损。目前，国内双转向轴车辆仍按国标GB7258．2004《机动车运行安全技术条件》转向 轮横向侧滑量要求，来定性检测第二转向轴轮胎与第一转向轴轮胎的平行度。本文论述了双转向轴车辆车 轮定位检测现状与不足，提出了双转向轴车辆车轮定位检测改善方案。 wheel iSvitaltothe control iS steering closely alignment performance，and [Summary]Vehicle relatedto wearoftruck axle．Wheelal includes inclination tyre steering ignmentmainly kingpin andtoe—in．Astodouble—front—axle angle，casterangle。camberangle steering thefirst axle besidesabove includes betweenthesecondand alignmentparallelism steeringtyres inclinationandcaster influencetruck control parameters．Kingpinangle anglemainly steering toe—inand influence wheellateral performance；andparallelismtyrewear．Steering sideslip distance ofnationalstandard formotorvehicles requirement GB7258—2004{Safetyspecification still the detectionof betweenthe onroads》iS to parallelism operating employedqualitative secondandthefirst axle ofdouble—front—axlevehiclesat steeringtyre steering present．ThiS wheel articlediSCUSScurrentsituationandinsufficientofdouble—front—axlevehicle steering enhancem
