Summary:

The continuously variable transmission (CVT) for automotive applications can better the transmission of power and fuel economy, a steel-belt design and clamping force for power transmission are under development by many researchers to increase the efficiency of a CVT and decrease the actuator power. The present work assesses the transmission efficiency with two electromechanical actuators system (TEMA) to modify the clamping force and DBCVT speed reduction ratio. The model is designed based on DBCVT simulation with TEMA package to evaluate the DBCVT component energy losses, transmission efficiency, and energy consumed by TEMA. According to the results, the TEMA effectiveness of the suggested DBCVT has a higher efficiency and improve energy losses than a single-belt CVT (SBCVT) but the average energy consumed by an actuator for SBCVT was lower than that of the TEMA with DBCVT throughout the new European drive cycle (NEDC). The average peak of the transmission energy losses of DBCVT is improved by 9.7% and 29% during UDC and EUDC, respectively, and the proposed DBCVT efficiency was increased by approximately (4.6% to 8.9%) compared to SBCVT during NEDC
