轿车驱动桥设计

摘 要

随着汽车工业的发展和汽车技术的提高，驱动桥的设计和制造工艺都在日益完善。驱动桥和其他汽车总成一样，除了广泛采用新技术外，在结构设计中日益朝着“零件标准化、部件通用化、产品系列化”的方向发展及生产组织专业化目标前进。

本说明书中，根据给定的参数，首先对主减速器进行设计。主要是对主减速器的结构，以及几何尺寸进行了设计。主减速器的形式设计为单级主减速器。而主减速器的齿轮形式主要有螺旋锥齿轮、双曲面齿轮、圆柱齿轮和蜗轮蜗杆等形式。本次设计采用的是齿轮形式是渐开式圆柱斜齿轮。其次，对差速器的形式进行选择，差速器的形式主要分为普通对称式圆锥行星齿轮差速器和防滑差速器两种。本次设计采用普通对称式圆锥行星齿轮差速器。最后，对半轴的结构、支承形式，以及桥壳的形式和特点进行了分析设计。本次设计采用半浮式半轴和整体式驱动桥壳。在设计之后对以上的零件进行了强度的校核，并用AUTOCAD和SOLIDWORKS绘制了二维和三维的图纸。 关键词：驱动桥、主减速器、差速器、ATUOCAD、SOLIDWORKS

ABSTRACT

With the development of the automotive industry and vehicle technology to improve the design and manufacturing process of the drive axle are increasingly improved. Drive Axle and other automotive assembly, in addition to the widespread adoption of new technology in the structural design, the direction of development and production organizations increasingly toward \ This manual, according to the given parameters, the first main gear box design. The structure of the main gear box, and the geometric dimensions of the design. The main gear box in the form of single-stage main gear box and two-stage main gear box. Final drive gear mainly in the form of spiral bevel gears, hypoid gears, cylindrical gears, worm and other forms. This design is integral single-stage main gear box, gear forms of hypoid gears. Secondly, in the form of differential selection, differential forms are divided into ordinary symmetric cone planetary gear differential and limited slip differential two. The design uses a common symmetric cone planetary gear differential. Finally, on the structure of the axle, supporting forms, and the axle housing forms and characteristics of the analysis and design. The design uses a full floating axle shaft bearing and the overall drive axle housing.After finishing the whole design,I use AUTOCAD and SOLIDWORKS to draw 2-D and 3-D pictures.
