Abstract
With the rapid development of automobile industry, automobile has become an indispensable means of transportation in modern society. However, with the growth of vehicle use time and the increase of driving mileage, the vehicle chassis, as a key part of bearing the vehicle weight, transmitting power and ensuring the driving stability, the problem of abnormal noise failure has become increasingly prominent. Chassis abnormal sound not only affects the driving comfort and safety, but also may indicate a more serious mechanical problems in the vehicle. Taking the abnormal sound fault of automobile chassis, this paper first summarizes the basic structure and working principle of automobile chassis, laying the theoretical foundation for the subsequent analysis. The mechanism includes the combination of mechanical vibration, wear and loosening. In terms of fault diagnosis, this paper introduces the current commonly used diagnostic techniques and methods, such as vibration analysis, acoustic detection, visual inspection, etc., and analyzes the advantages and disadvantages of each method and the scope of application. In the analysis part of chassis abnormal sound fault, this paper expounds the specific performance, causes and diagnosis ideas of four categories of suspension system, braking system, transmission system, body and accessories. Finally, this paper puts forward the maintenance countermeasures and preventive measures for all kinds of chassis abnormal sound faults. For the suspension system, the maintenance and replacement of shock absorbers and suspension spring; the maintenance of brake pads and brake discs, the maintenance and maintenance of transmission and inspection and replacement of drive shaft; for body and accessories, the strengthening, maintenance and tightening of the body structure and accessories are emphasized.
