摘要 本次畢業(yè)設(shè)計主要是對安裝在驅(qū)動橋的兩個半軸之間的差速器進行設(shè)計，主要涉及到了差速器非標(biāo)準零件如齒輪結(jié)構(gòu)和標(biāo)準零件的設(shè)計計算，同時也介紹了差速器的發(fā)展現(xiàn)狀和差速器的種類，對于差速器的方案選擇和工作原理也作出了簡略的說明。在設(shè)計中參考了大量的文獻，因此對差速器的結(jié)構(gòu)和作用有了更透徹的了解，通過利用Proe軟件對差速器進行建模工作，也讓我在學(xué)習(xí)方面得到了提高。 參考了東風(fēng)EQ1090E載重汽車驅(qū)動橋，在論述載重汽車汽車驅(qū)動橋運行機理的基礎(chǔ)上，提練出了在驅(qū)動橋設(shè)計中應(yīng)掌握的滿足汽車行駛的平順性和通過性、降噪技術(shù)的應(yīng)用及零件的標(biāo)準化、部件的通用化、產(chǎn)品的系列化等三大關(guān)鍵技術(shù)。 關(guān)鍵詞：差速器；標(biāo)準零件；齒輪結(jié)構(gòu) I Abstract This graduation design is mainly carries on the design to the differential is mounted between the 2.5 axis of the drive axle, mainly related to the design of differential non standard parts such as gear structure and standard parts of the calculation, and the types of the development status and the differential differential is also introduced, the selection of schemes and work principle in differential also made a brief description. In reference to the design of a large number of literature, so the structure and function of the differential have a more thorough understanding of the differential work, by modeling using Proe software, also let me learn improved. The reference of Dongfeng EQ1090E truck drive axle, based on analyzing the truck driving axle of automobile running mechanism, refined the in the driving bridge design should be mastered meet automotive ride comfort and through sex, noise reduction technology application and the standardization of parts, components of the general, a collection of products three key technology. Keywords: differential gear structure; standard parts;gear structure
