Abstract
Portal axle unit is a gearbox unit installed on every end axles of the vehicle. They are installed to the vehicle to give higher ground clearance to enable vehicle to go over large obstacle when driving in off-road conditions. Shafts designed must be exceptionally tough and lightweight to improve the overall performance of the portal axle unit. In this paper, the design of the hollow shaft with rib attached at each end is analysed in detail. Selected parameters of the rib are studied to further optimize the proposed shaft design. Finite element method (FEM) is employed to simulate stress analysis on the shaft models. Torque delivered from the engine to the shaft and the shaft's weight is considered in the FEM simulation. The stress and weight reduction results are calculated for optimum shaft, existing shaft and solid shaft for comparison. The optimum model of the shaft shows slight improvement over the existing shaft.
