Mechanics Analysis and Finite Element Solution on Tapper Assembly of Automobile’s Drive Axle

Mechanical research on structural strength is done for the driving taper assembly of automobile in this paper, of which the assembly process is also explained. Based on theoretical analyses of the connection between tighten torque and axle force, the analytical model of the main reducer is established. In order to get the stress field and displacement field of the main reducer after assembly, which is used to conduct strength check, finite element analysis method is introduced. Based on these results, some theoretic suggestions for design and manufacture of the main reducer are provided.
