Main Drive Vehicle of Two-Stage Driving Axle Design

In this paper, the overall requirements for the design of the drive bridge is analysed, the programme of the structure on the drive axle assembly and component parts is studied. The overall design and programme design on the drive axle assembly is finished; the basic structure of the double reduction final drive and the middle tandem axle is ensured which refers to the structure of the reference model CA1092; The basic components on the drive axle assembly are designed. The calculation of their basic geometric parameters is finished, and the strength of the parts which have greater impact on the overall strength is checked; and the remaining components are designed briefly. The paper gave a briefing on the characteristics of Solidworks 2008 software and virtual assembly technology. Introduces three-dimensional maps of parts which are draw by SolidWorks software and describes drive axle assembly by the form of diagrams.
