Axle transmits power from the gearbox to the wheels. There are primarily two reasons for reducing the axle’s diameter in the case of a bipod CV joint (Constant-velocity joints axle), to avoid overdesigning and less articulation angle. As the ATV (All-Terrain Vehicle) goes in bumps and droops, a driveshaft with a larger diameter would hit the walls of the CV joint, which will create a hindrance in its articulation. Moreover, if the driveshaft is overdesigned, it will add unnecessary weight and effort to the power train, which would decrease the overall performance of the vehicle. The diameter of the axle was reduced using real-time testing data of peak torque production from the powertrain unit (Engine + CVT (Continuously variable transmission )+ Gearbox) with the help of various machines to validate that component do not fail under the given load conditions; research work is divided into 3 phases of data collection, axle design, and validation.
