- Abstract— Axle transmits power from the gearbox to the wheels. There are primarily two reasons for reducing the Axles diameter in the case of a bipod CV joint namely, to avoid overdesigning and less articulation angle. As the ATV goes in a bump/ droop, a driveshaft with a larger diameter would hit the walls of the CV joint which creates hindrance in its articulation. And, 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. We have reduced the diameter of the axle using real-time testing data by taking the help of various machines to validate that component not failing under the given load conditions; research work is divided into 3 phases of Data collection, Axle design, and validation. Total 3 test rigs were set up for Data collection and validation, combined with axial design, material selection, heat treatment, and CAE validation. Whereas efficiency of Powertrain (CVT) is also calculated as 0.87 from test rig1 which further drops to 0.75 with time. An 18% reduction in Diameter is achieved throughout the research leads to higher articulation and weight reduction. An analytical, numerical, and experimental result comparison is also performed on the axle as the result comparison
