Method of Synthetic Detection and Judgment on Truck Drive Axles Assembly

介绍了一种自行设计制造的专用检测试验机，论述了汽车后桥主锥总成综合检测和评判方法。试验机模拟了汽车行驶时的工作状况，能自动检测主锥总成的预紧力矩、转动中的发卡和干扰、差速等参数值。以检测到的各项数据为依据，对立锥总成的整体性能作出综合评定，给出了评判结果，并提出工艺改进。

In this paper the method of synthetic detection and judgment on truck drive axles assembly is discussed. Entirety performance of truck drive axles assembly is evaluated by parameter values of preload-moment of roller bearings, stiffness and interference of the turning, performance of differential rate etc. The judgment results are given, and the technological improvement is presented. This paper also introduces a test machine designed specially for detection. All kinds of important data of truck drive axles assembly are analyzed and processed by PC. The machine is successfully used in truck drive axles assembly line, whose effect and efficiency are noticeable.
