柴油动力SUV乘用车设计(后驱动桥与后悬架设计)
摘要
汽车快速的发展与更新换代,汽车技术也在不断地提高,汽车驱动与悬架方面也在渐渐的完善。跟别的总成一样,汽车驱动桥与悬架采用了很多的新技术、新工艺零部件越来越多的采用通用规格、标准规格。
驱动桥的位置是整个汽车传动的末尾,后悬架与后驱动桥的设计往往有一定的关系后驱动桥是有主减速器,再加上差速装置和壳体还应该再加上一些传动装置,驱动桥还要承受一些汽车行进过程中的作用力,它还需要承担汽车的汽车的降速増扭等作用。而后悬架,特别是非独立悬架往往以后驱动桥壳为刚性结构传递载荷,悬架主要是用来缓和车身的力量冲击还有载荷的传递与衰减,车身车架与驱动桥之间的弹性链接为弹簧,与簧载质量与费簧载质量共同组成的系统就是汽车,悬架中还有减震器,它是一种阻尼元件,悬架还有一些横向拉杆,可以抵消汽车侧向力,悬架的设计还需考虑一些关于半轴的设计,半轴与车轮桥壳的链接方面。驱动桥结构跟悬架的结构有关系,整体式桥壳在很多强狂下我们都是见到的它是度路悬架,有时可能会使半独立的,因此,设计驱动桥和悬架需要相互借鉴与参考。

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 nee
