车轮定位仪检定方法研讨

A Study of Wheel Alignment Gauge Inspecting Method

车轮定位仪是用来测量汽车转向系统定位参数的专用仪器,它可用于测量转向轮的外倾角、主销内倾角、主销后倾角、转向随动角、车轮最大转角和转角差、车轮前束及前后车轮问的几何关系等参数。目前国内尚无一整套完善的测试方法及检定规程。对此.本文结合作者实际工作,对车轮定位仪检定原理和方法作了研讨。

Wheel alignment gauge is a special instrument for measuting positioning parameters of vehicle steering system, including wheel camber, kingpin inclination, wheel caster, steering locking angle,toe-in and geometic relations between front and real wheels etc. There is not a set of measuring method and inspecting regulation now in China. With the development of auto manufacturing industry , this inspecting method must be put on the agenda.
