Dynamic Analysis of a Continuously Variable Transmission and Effects on Vehicle Performance

CVT is a transmission system widely applied in automobiles due to its better efficiency of the vehicle available power. That happens because of the continuously variation of the transmission since its pulleys mechanisms makes it possible for them to open or close according to engine speed and resistive forces. This paper presents a dynamical analysis of a CVT Transmission that utilizes a rubber belt. It is considered that the influence of the pulley’s mechanisms and the axial movement of the belt, and these effects in the vehicle longitudinal dynamics.
