Design and Analysis of Input Shaft of a Portal Axle

Abstract

The input shaft of portal axle is used to recive the power from differential unit and sends it to portal axle unit and the output shaft transfer the power from portal axle unit to road wheels. The main objective of this project is design and analysis of input shaft of a portal axle unit with different thickness of hollow shafts. The portal axle input shaft models were modeled and analyzed using ANSYS software and validated through comparison of results with the analytical results. In the analysis of the input shafts of the portal axle, the hollow shaft with 3mm thickness is proposed and the final element model is built. The optimum set of parameters it is found that the hollow shaft thickness affects the shear strength of the hollow shaft compared to the solid shafts. The optimized shaft has an improvement in shear strength and the weight of the shafts shaft is will be reduced.
