Abstract

The embodiment of the invention provides a prediction and diagnosis method and system for a gear fault of a drive axle main speed reducer. The method comprises the steps that a vibration accelerationsignal of the drive axle main speed reducer is collected; according to the vibration acceleration signal, a vibration value of a gear engagement order of the drive axle main speed reducer is determined; and the vibration value is compared with a preset vibration threshold value, a prediction diagnosis result is determined, and the prediction diagnosis result is used for indicating whether the drive axle main speed reducer gear needs to be repaired and maintained or not. According to the method provided by the embodiment of the invention, the problems that in the prior art, only offline detection can be carried out, the gear of the drive axle main speed reducer cannot be predicted and diagnosed, and then the safety problem of a vehicle in the running process cannot be ensured can be solved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of detection, and in particular to a method and system for predicting and diagnosing a gear failure of a drive axle final drive. Background technique [0002] The drive axle is an important part of the automobile transmission system, which is responsible for the transmission of power. During the working process of the drive axle, the abnormality of any part will cause the drive axle to work abnormally. [0003] Among them, during the driving process of the vehicle, pitting corrosion, wear, broken teeth and other problems affecting the driving performance of the drive axle main reducer gear will occur. In order to solve the above problems, the drive axle off-line detection system is usually used to judge the drive axle main reducer Whether the gear is abnormal. [0004] However, the drive axle off-line detection system can only be used when the product is off-line, that is, it ca...
