Abstract Drive axle is the one of automobile four important assemblies. It’s performance directly influences on the entire automobile , especially for the Sports Utility Vehicles . Driving axle set at the end of the transmission system. The basic function of driving axle is to increase the torque transported from the transmission shaft or transmission and decrease the speed ,then distribute it to the right 、 left driving wheel, another function is to bear the vertical force 、 lengthways force and transversals force between the road surface and the body or the frame. In order to obtain a good power performance, safety and trafficability characteristic, engineers must promote quality and level of design Driving axle design of the Zotye2008 Sports Utility Vehicles mainly contains: main gear box, differential, transmitted apparatus of wheel and the housing of driving axle. The main gear box adopted single reduction gear and the differential adopted mon, symmetry, taper, gear. Transmission apparatus of wheel adopted full floating axle shaft, and the housing of driving axle adopted the whole pattern,and proofread interrelated parts. During the design process, CAXA drafting software is used to expresses the wholes to assemble relationship and part drawing by drafting. Key words : driving axle; main gear box; differential; half shaft; housing 充值下载即送 CAD 图纸, QQ 36396305 答辩无忧,值得下载! 目录第 1章绪论................................................................................................................... 1 驱动桥简介.......................................................
