This paper presents a detailed continuous one-dimensional transient-dynamic model of a metal V-belt continuously variable transmission (CVT) for control applications. The simulation model developed captures the power transmission characteristics and inertial dynamics of a metal pushing V-belt CVT. The torque transmitting mechanism of a metal V-belt CVT under the conditions of high load torque, constant driven pulley axial force and a constant driver pulley input torque was studied. The results discuss the performance of a metal V-belt CVT system model under transient and steady state operating conditions. The model proposed in this work expounds a relationship between the transmission ratio change and pulley actuation force, which will serve as a powerful tool for the development of fast and reliable CVT controllers to meet the objectives of reduced losses, higher torque capacity, higher vehicle fuel economy and better acceleration performance.
