某轻型货车驱动后桥总成设计 摘要 驱动桥是汽车总成中的重要承载件之一，其性能直接影响整车的性能和有效使用寿命。驱动桥一般由桥壳、主减速器、差速器和半壳等元件组成，转向驱动桥还包括各种等速联轴节，结构更复杂。 传统设计是以生产经验为基础，以运用力学、数学和回归方法形成的公式、图表、手册等为依据进行的。现代设计是传统设计的深入、丰富和发展，而非独立于传统设计的全新设计。以计算机辅助设计技术为核心，以设计理论为指导，是现代设计的主要特征。利用这种方法指导设计可以减小经验设计的盲目性和随意性，提高设计的主动性、科学性和准确性。 同样，对驱动桥的研究不应仅停留在传统设计方法上，而应借助于现代设计方法以精益求精。本毕业设计对研究驱动桥所涉及的现代设计方法做了比较深入的分析，提出各种设计方法互相结合，针对不同的设计内容分别应用不同的方法，以促进其设计过程趋于合理化和科学化。首先通过查阅各种汽车驱动桥设计的文献以撰写设计说明书和各种计算公式结果，然后对驱动桥各零部件进行三维建模，分析设计过程是否存在干涉或者其它问题，最后通过三维模型出工程图，用CAD修改图纸以便加工部对图纸的查阅。 关键词：主减速器；减速器；桥壳；计算机辅助设计 全套图纸，三维加153893706  A light-driven rear axle assembly design ABSTRACT Drive axle is an important carrier of automotive assembly, its performance directly affects the performance and useful life of the vehicle. Usually by the axle drive axle, the main reduction gear, differential and half-shell and other components, steering drive axle also includes various coupling constant, the structure is more complicated. Traditional design is based on production experience, to apply the formula mechanics, mathematics and regression method of forming, charts, manuals, etc. as the basis for the. Modern design is the traditional design of deep, rich and development, rather than independent of the traditional design of the new design. In computer-aided design technology as the core, design theory, are the main features of modern design. Using this method can reduce the experience to guide the design design of blindness and randomness, the initiative to improve the design, scientific and accurate. Similarly, the study of the drive axle should not only stay in the traditional design methods, but should by means of modern design methods to excellence. The graduation of Modern Design Method of driving axle involved in doing more in-depth analysis, various design methods combined with each other, for different design elements were applied different methods to promote their design process rationalization and scientific . First, a review of various automotive d
