Continuously Variable Transmission (CVT) system offers smooth transition between variable transmission ratios to improve the acceleration performance and reduce fuel consumption and vehicle’s emissions. Currently, most of the developed CVT system is actuated by an internal hydraulic circuit where compressibility of oil introduces non-linearity to the system, causing unwanted difficulty in controlling the response of CVT. Therefore, a new design which is free from hydraulic system is proposed to overcome the shortcomings in the existing CVT without losing its performance. The proposed CVT system is designed based on the belt-driven type consists of two sets of sectional pulley. A set of sectional pulley is actuated by an electric motor using slider crank mechanism. The sectional pulleys are arranged in radial direction which is able to slide inward and outward of the carrier.
