随着道路质量(品质)的提高和高等级公路及高速公路的发展,汽车行驶速度愈来愈高,因而对车轮的平衡度要求也愈来愈严格。汽车在高速行驶时,由车轮不平衡所造成的车轮跳动和摆振不仅会影响汽车的行驶平顺性,而且使汽车难以控制(操纵稳定性变差),影响汽车行驶的安全性。此外,还会加剧轮胎及有关机件的磨损和冲击,缩短汽车的使用寿命。因此必须重视车轮的平衡。
With the improvement of road quality (quality) and the development of high-grade highways and highways, the car travels higher and higher, and the requirements on the balance of the wheels are also getting more and more stringent. When the car is running at high speed, the wheel runout and shimmy caused by the imbalance of the wheel not only affect the ride comfort of the car, but also make the car difficult to control (the steering stability deteriorates) and affect the safety of driving of the car. In addition, it will exacerbate the wear and impact of the tire and related parts, shortening the service life of the car. Therefore, we must pay attention to the balance of the wheel.
