1、毕业设计说明书论文(全套CAD图纸)QQ36396305摘要驱动桥的零件很多,结构复杂.驱动桥作为汽车四大总成之一,它的性能的好坏直接影响整车性能。本文主要是关于速腾1.8T驱动桥设计。驱动桥的基本功用是将传动轴或变速器传来的转矩增大并适当降低转速后分配给左、右驱动车轮,其次驱动桥还要承受路面和车架或车身之间的垂直力、纵向力和横向力,以及制动力和反作用力矩等。驱动桥组成包括主减速器、差速器、半轴、万向节、驱动桥桥壳等。驱动桥是汽车传动系中主要总成之一。驱动桥的设计是否合理直接关系到汽车使用性能的好坏,驱动桥是汽车中的重要部件,它承受着来自路面和悬架之间的一切力和力矩,
2、是汽车中工作条件最恶劣的总成之一,如果设计不当会造成严重的后果。本文以驱动桥的传统设计方法为基础,详细研究了速腾1.8T轿车的驱动桥的设计方法,提出了比较可行的设计思路。根据这一思路设计计算出数据并画出转向驱动桥的各零件图。同时我也查找了现有的速腾1.8T轿车的驱动桥的结构原理,从样车对驱动桥的整体构造加深了解,结合最新有关驱动桥的信息和汽车设计书本上的知识来设计计算、绘制草图,然后运用AUTOCAD软件绘制总装配图,从而提了设计工作效率。关键词:汽车驱动桥主减速器差速器半轴41毕业设计说明书论文(全套CAD图纸)QQ36396305AbstractDrivingax
