Design of drive axle for unmanned pure electric logistics vehicle
Abstract
With the increasing awareness of energy crisis and environmental protection, people pay more attention to pure electric vehicles. Some potential traditional automobile manufacturers at home and abroad often position their products in a high level, so it is difficult to popularize them among majority consumers. As a supplement to middle and high level pure electric vehicles, small and micro pure electric vehicles will reveal a great development potential. This kind of pure electric vehicle has the advantages of compact structure, light weight and low cost.
In this paper, the driving axle of an unmanned electric logistics vehicle based on XinShiQi Company is designed with the help of three-dimensional modeling software CATIA, and finite element analysis software ANSYS. In the design, the characteristics of the drive axle are explained firstly. According to the given data, the structure types and parameters of the final drive, differential, half shaft and universal joint are determined, and the strength is checked. Through calculating the size and referring to the similar parts of the existing vehicle, carry out the 3D model. Then import the model into finite element analysis software to obtain stress nephogram. The results are of great significance to the design and development of the driving axle of the electric logistics vehicle.
