[0002] As a heavy-duty mining machinery, electric wheel dump trucks integrate mechanical, electrical and hydraulic functions. Moreover, mining electric wheel dump trucks have poor operating conditions, large dust, high load and high strength. Most of them are operated in shifts without stopping. Objectively, the quality of parts is unstable and subjectively, improper use and maintenance make the failure of electric wheel dump trucks hidden, complex, diverse and uncertain. When it fails, it is increasingly difficult to determine the cause of the failure using manual experience and traditional diagnostic technology. This undoubtedly brings great difficulties and challenges to the fault diagnosis and maintenance of dump trucks.
