The Diagnosis and Analysis of Shanghai GM Buick’s Steering

System

Abstract：This paper expounds all aspects of function, composition, main structure, working principle and the possible fault of the Shanghai GM Buick’s steering system, according to the structural principle analysis to that , the abnormal sound system, the steering wheel is too loose or too recoil, the steering wheel can’t return or is automatic wandering when running straightly, the steering is heavy , the steering wheel steering vibration, braking direction and the other common running deviation of the cause of the failure and ruled out ways in which focuses on the analysis to the heavy several situations. At the same time, putting a forward to a fault maintenance feasible scheme; Using the theory and practice method, to each problem has a good understanding, to use the content of good summary, to further familiar with buick steering system of various aspects knowledge, analyse the reason of failures, and concluded that diagnosis scheme and ruled out.

Keywords：Buick; Steering System; Fault Diagnosis; Analysis
