The transmission gear design parameters to determine the driving bevel gear shaft bearing, making the check of bearing life and strength. Basing on gear structure parameters and vehicle parameter, design a light truck axle housing, making a establishment of the light trucks dimensional axle housing Pro/E model, checking axle housing were five conditions working strength. After theory checking,importing CAD model into ANSYS Workbench software,making finite element analysis of axle housing, access to five conditions equivalent stress and strain contours. Finally making sure the strength of axle housing design models.
