(Jiangling Motors Corporation, Ltd. , Nanchang Jiangxi 330000, China) Abstract: Transmission is the core part of the vehicle, and the study of transmission directly affects the vehicle NVH performances.
Therefore, transmission NVH performance is an important indicator of the vehicle performance in the process of vehicle development. Transfer
paths mechanism of transmission was analyzed, the scheme of adding stiffeners to the transmission case and optimizing the parameters of the
transmission tooth profile was formulated. Through simulation analysis, subjective evaluation and objective test, it is proved that the order
noise of vehicle is improved obviously, and this method can effectively solve the problem of transmission rattle. Keywords: Transmission; Rattle; Order noise; Transfer error
