While driving vehicles on countryside road or off road conditions, obstacles in the road may cause damage to vehicle. To avoid that portal axle is designed to increase ground clearance of the vehicle. In this work a vehicle model was considered and portal axle was designed for it. The high ground clearance depends on the arrangement of gear train of the portal axle. The gear train and shafts are the most critical part of the portal axle as they transmit and withstand very high loads. They should be designed to withstand overloading and lightweight for greater durability and performance of the portal axle. Stress analysis of the gear train and shafts are necessary in evaluating the design for gear train and shaft. The characteristics of the gear train of the portal axle were investigated by analyzing the gear contact stresses, bending stresses of the gears by using finite element analysis (FEA) software such as ANSYS.

Keywords: Portal axle, Torque calculation of vehicle, FEA analysis of gear train, off road vehicles, Design of gear train.
