公路状况的改善及汽车速度的提高,使汽车车轮的专项动平衡检验校准日趋重要。目前,汽车维修企业在用的专门车轮动平衡机种类繁多,型式各异,但功能相似。它们在使用中陆续发现一些问题及故障,现对其典型的几个问题进行分析探讨,以求得合理的解释与正确的解决。一、数据“飘移”问题。一个车轮在同一台平衡机上,反复作几次平衡检验或者校准检验,其结果数据不尽相同(此种现象相当普遍)、数据或不变或相差几克至十几克不等.经过综合比较分析,有如下几个主要方面的原因:①设备自身的压力传感器故障或紧固部件松动;②设备自校准功能失效(SELF-
The improvement of road conditions and the increase of car speed make the test and calibration of the special dynamic balance of automobile wheels become more and more important. At present, there are many kinds of special wheel balancing machines used by automobile maintenance companies in different styles but with similar functions. In the course of their use, they have successively discovered some problems and faults, and now they analyze and discuss several typical problems in order to find a reasonable explanation and a correct solution. First, the data “drift ” problem. A wheel on the same balancing machine, repeated several times to balance test or calibration test, the results of different data (this phenomenon is quite common), the same or different data or a few grams to a dozen grams range.After a comprehensive comparison Analysis, there are several main reasons for the following: ① equipment pressure sensor failure or loose parts; ② equipment self-calibration function failure (SELF-
