柴油动力SUV乘用车设计（后驱动桥与后悬架设计 摘 要 。关键词：，，， The Great Wall after the hover SUV drive axle and rear suspension design ABSTRACT Rapid development and upgrading, car technology is also in constant increase, motor drive and suspension are also gradually improve. Like other assembly, Automotive drive axle and stop using lots of new technology, new technology, more and more a part of the general specification, standards, specifications. Drive axle position is at the end of the car drive, drive axle suspension and after the design of the drive axle is tend to have a certain relationship with the Lord reducer, differential and axle housing and gear wheel, drive axle on some forces in the process of car travel, but it also needs to take the car slow down raised twist, etc. And then suspension, especially not independent suspension after often drive axle housing for rigid structure load, the power of suspension is mainly used to temper the body impact and load transmission and attenuation, Elastomer the connection between the frame and drive axle of spring, sprung mass and car of sprung mass system, suspension shock absorber, damping elements, is a kind of suspension, and some of the pull rod can offset a lateral force, the design of the suspension design also need to consider some half shaft, shaft and shaft sleeve links. The structure of the drive axle suspension structure,one-piece axle housing is generally independent suspension or half independent suspension, therefore, the design of drive axle and suspension needs mutual reference and reference.
