Integrated design of the torsion beam electric driving axle

Abstract

In view of the problems in the use of wheel side drive system, torsion beam type electric driving axle is proposed for the solution. First, with the vehicle parameters of a certain electric vehicle as a sample, the torsion beam driving axle is matched and designed and the three-dimensional model was drawn with the help of CATIA; secondly, the stiffness and strength of the driving axle are analyzed with the help of ANSYS software under five working conditions; finally, the modal analysis of the driving axle structure is carried out. It is verified from the three aspects of stress, deformation and inherent mode that the designed driving axle can meet the limit requirements of China's national standards for vehicle driving axles, which proves the rationality and effectiveness of the design scheme.
