Analysis of Abnormal Noise of Starter Tooth Retreating during Starting of a Certain Type of Vehicle
With the continuous development of the automobile industry and the continuous application of new technologies,the driving experience and driving quality of passenger cars have been improved,and consumers have had higher requirements for the driving comfort and overall NVH performance of passen-ger cars.Due to the structure and power constraints of traditional passenger car starter,abnormal sound,trailing sound,vibration,tooth retreating sound and other problems often occur during starting,which af-fect the NVH performance of passenger cars.This paper analyzes the mechanism and influencing factors of the abnormal noise of a new vehicle when starting.Through the optimization of P-axis gear parameters of starter,NVH performance test and subjective test drive review,the effect of P-axis gear parameter opti-mization on reducing starting noise was studied.The results show that by optimizing the parameters of the P-axis gear,the abnormal noise of the starter is reduced.
