随着我国高速公路建设迅速发展,汽车车速加快到100～120 km/h,对汽车行驶安全性能的要求越来越高,特别是对汽车行驶系和转向系的要求越来越高,其目的是为保证汽车操纵稳定性和减少轮胎的磨损。由于车速的提高,会加速汽车悬架和转向系中的元件磨损、变形等,使车轮定位发生变化,从而导致轮胎偏磨、爆破甚至发生严重的事故。因此,高速行驶的车辆,为提高其操纵稳定性和减少轮胎的磨损,加强车轮定位参数的检查与维护就显
With the rapid development of highway construction in our country, the speeding up of vehicles to 100-120 km / h has become more and more demanding on the driving safety performance of vehicles, especially the requirements on the driving and steering systems of automobiles are getting higher and higher. Is to ensure vehicle handling stability and reduce tire wear. As the speed increase, will accelerate the car suspension and steering system components wear, deformation, so that the wheel positioning changes, resulting in tire wear, blasting and even serious accidents. Therefore, high-speed vehicles, in order to improve the handling stability and reduce tire wear and tear, to strengthen the inspection and maintenance of wheel alignment parameters were significant
