The structural design of the integrated electric drive axle of 2 tons pure electric logistics vehicles
Abstract
The mainstream trend in automotive research and development nowadays is electrification, and one of the keys to electrification for vehicle is the electrification of the drive axle. This design refers to the traditional truck drive axle design method, combined with the motor unit, to design a relatively reasonable integrated electric drive axle.
With the given data, design and analysis the overall parameters of vehicle.Determine the parameters of the motor to ensure that the power of the vehicle meets the needs of use.Determine the form of the final drive, choose the appropriate form to ensure that the structure of the drive axle is simple and small, design and calculate the reducer gears and check strength of it. Determine the form of the differential and do the design, calculation and strength check of the differential bevel gear. Select the suitable drive shaft, complete the design, calculation and strength check. Select the form of axle housing and combined with finite element analysis to check the strength of it.
After determining the parameters, use the modeling software CATIA to complete the 3D models about each parts ,export the 2D drawings, using CAD to modify and improve them. to ensure that the structure in the assembly drawing and part drawing is clear and complete.Finally, use the finite element analysis function of CATIA to complete the analysis of the electric drive axle about check strength and stiffness.
Key Words:electric drive axle; integrated design;CATIA;finite element analysis
