摘 要
變速器是汽車傳動系統(tǒng)的重要組成部分，它的性能直接影響到汽車的動力性和燃油經濟性，因此變速器的設計是關系到汽車整體使用性能的重要總成設計。
本次設計主要研究了中間軸式五擋手動變速器，主要設計內容包括變速器傳動機構方案的選擇分析；變速器主要參數的計算；變速器操縱機構的設計；變速器傳動機構的計算及其校核；變速器軸承的選擇計算及校核；同步器的設計計算及選用；變速器箱體的結構設計。最后，經過整體的計算、分析與校核，設計出結構性能合理、符合技術要求的變速器。
關鍵詞：變速器；傳動比；參數；設計計算；校核
ABSTRACT
Transmission is an important part of automobile transmission, which directly affects the performance of vehicle dynamics and fuel economy, so the design of transmission is related to the overall performance of major vehicle assembly design.
The design of the main shaft of the middle five-speed manual transmission, the main design elements include the choice of transmission of transmission programs; transmission main parameters of the calculation; transmission control mechanism design; transmission, calculation and check of drive mechanism; transmission bearing The choice of calculation and checking; synchronizer design calculation and selection; transmission box structure design. Finally, after the whole calculation, analysis and verification, the performance and structure of the transmission is reasonable, meeting the technical requirements of transmission.
