四轮定位检测的必要性九十年代后,随着汽车技术的发展,为适应汽车高速、稳定、舒适的需要,轿车的悬挂系统,几乎均采用了四轮独立悬挂装置,并逐步以“麦费森氏”独立支柱悬挂装置,取代传统的“SALA”悬挂系统。麦氏悬挂系统的前后轮定位角,完全依赖于在一个统一的基准线上的相互合理匹配,来实现车辆转向行驶系统的稳定效应。因而对车辆前后车轮定位角参数值的准确性、匹配性,提出了更高的技术要求,其检测 Necessity of Four-wheel Positioning Detection After the 1990s, with the development of automobile technology, in order to meet the needs of high-speed, stable and comfortable cars, almost all of the suspension systems of cars were equipped with four-wheel independent suspension devices, Fei Sen’s “independent pillar suspension, replacing the traditional” SALA "suspension system. Maxwell suspension system front and rear wheel positioning angle, relies entirely on a uniform baseline of mutual reasonable match, to achieve the stability of the vehicle steering system. Therefore, the vehicle front and rear wheel positioning angle parameters accuracy, matching, put forward higher technical requirements, the test
