【正文】 esign calculation process, the design part describe the subactuator’s design process. The design is mainly divided into design and technology parts, select configuration, main parameters, gear design, shaft design, calculation check, and design of other structural ponents. Crafts part mainly diagnose typical ponent’s technology process, determine the materials of all kinds of ponents. Keywords: Subactuator。設(shè)計部分較詳細的敘述了分動器的設(shè)計過程，選擇結(jié)構(gòu)方案、主要參數(shù)、齒輪設(shè)計、軸設(shè)計、計算校核、其他結(jié)構(gòu)部件的設(shè)計。分動器也是一個齒輪傳動系統(tǒng)，它單獨固定在車架上，其輸入軸與分動器的輸出軸用萬向傳動 裝置連接，分動器的輸出軸有若干根，分別經(jīng)萬向傳動裝置與各驅(qū)動橋相連。這就要求增加汽車驅(qū)動輪的數(shù)目，因此，越野車都采用多軸驅(qū)動。 目 錄 摘 要 .....................................................................................................
