This paper uses a nonlinear finite element technique,through establishing the fi-nite element model of the axle housing、the main gear box and the bolt,analyzes the dist-ribution of contact pressure between the axle housing with the main gear box shell com-bination surface under three influence of load cases and the with the relationship of bolt preload and the combination of surface,and find out the largest area of strain and the ea-sy oil spill area.So,it can provide a reliable basis for product design and improvement.
