Abstract: Constant Velocity (CV) Joint or driveshaft is important drivetrain component of automotive vehicles considering vehicle dynamics like driving performance, handling, NVH etc. It transfers power/torque received from gearbox to wheels at wide variety of angles at constant velocity. This paper explains the methodology of static and dynamic analysis of CV joint, which is followed during initial stage of product design selection. Failure to do this may result in incorrect CV joint selection in the design stage itself and/or safety concerns if CV joint dislodges from gearbox during operation, which may lead to safety of occupants in the vehicle and pedestrians too. Along with static analysis, dynamic analysis of CV joint ensures all operating points of inboard joint nominal center fall within acceptable design limit of joint extreme capacity. Based on this study, one can establish a better understanding of CV joint stroke-angle selection, which will reduce cost, help to meet vehicle timeline and improve customer satisfaction.
