Abstract: This work presents the development of an alternate powertrain for hybrid vehicle called the ‘Torque Enhancer’. It is a planetary gear system with a sun gear, an internal ring gear, three planet gears, a planet carrier and an outer ring casing. The primary inputs from the electric motor (EM) and an internal combustion (IC) engine were connected to the sun gear and the planet carrier respectively. The ring casing provides the necessary output. The sun gear and the planet carrier were coupled to generate higher torque and higher rpm at the output. The 3D modelling and simulation for dynamic motion were performed in SOLIDWORKS 2018. The results showed that a higher rpm and a higher torque were achieved on the output ring casing. For design optimization, a Nonlinear- Dynamic Study was performed to check for different analysis like the Stress, Displacement, Strain and velocity for different designs of carrier plates. The Stress, Strain and velocity decreases with the thickness, the displacement is found to be almost constant around 25mm and the velocity decreases with increase in thickness. A ribbed carrier plate of thickness 4mm is chosen to be the most optimized carrier plate.
