轎車驅動橋畢業設計
摘要

隨著汽車工業的發展和汽車技術的提高，驅動橋的設計和制造工藝都在日益完善。驅動橋和其他汽車總成一樣，除了廣泛采用新技術外，在結構設計中日益朝著“零件標準化、部件通用化、產品系列化”的方向發展及生產組織專業化目標前進。
本說明書中，根據給定的參數，首先對主減速器進行設計。主要是對主減速器的結構，以及幾何尺寸進行了設計。主減速器的形式設計為單級主減速器。而主減速器的齒輪形式主要有螺旋錐齒輪、雙曲面齒輪、圓柱齒輪和蝸輪蝸桿等形式。本次設計采用的是齒輪形式是漸開式圓柱斜齒輪。其次，對差速器的形式進行選擇，差速器的形式主要分為普通對稱式圓錐行星齒輪差速器和防滑差速器兩種。本次設計采用普通對稱式圓錐行星齒輪差速器。最后，對半軸的結構、支承形式，以及橋殼的形式和特點進行了分析設計。本次設計采用半浮式半軸和整體式驅動橋殼。在設計之后對以上的零件進行了強度的校核，并用AUTOCAD和SOLIDWORKS繪制了二維和三維的圖紙。
關鍵詞：驅動橋、主減速器、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 "standardization of parts, components universal product series" professional goal.
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.
Keywords: Drive axle、Main reducer、Differential、AUTOCAD、SOLIDWORKS
