【Abstract】CVT transmission is widely used in the automotive market due to its good shift and acceleration smoothness. Aiming at the common screeching problems of CVT transmission,this paper uses NVH professional method to analyze the impact of structure,transmission path,etc. on screeching problems,so as to provide a highly operable solution,and at the same time play a certain reference role for other types of transmission screeching problems.
【Key words】squealing;CVT transmission;NVH;transfer path
