Computer Aided Engineering Analysis of Four-Wheel Drive Mechanical Powertrain of an Electric All-Terrain Vehicle (e-ATV)

An Electric All-Terrain Vehicle (E-ATV) can able to run in a rough and rugged terrain conditions. The four-wheel drive (4WD) powertrain of the E-ATV provides enough traction to the vehicle to maneuver over the terrain surface by providing significant amount of power and enough traction. The mechanical powertrain has components such as gearbox, differential, Continuous Variable Transmission (CVT), propeller shaft and Drive shafts, etc. For successful implementation of the powertrain system, it must follow some steps such as mathematical modeling, designing, analyzing, manufacturing, assembling and testing the powertrain components. An electric motor provides power to the Continuous Variable Transmission (CVT). The CVT in turn transmits the power to a two-stage reduction gearbox. The gearbox then transmits the power to four wheels using drive shafts and propeller shafts via differentials in front and rear. For Computer aided designing (CAD), SolidWorks is used. For Computer Aided Engineering Analysis (CAE), Ansys is used. MATLAB Simulink software is used for checking system level performance of a modified CVT.
