Transmission speed bya variable speed transmission and control mechanism of two parts. The main role of the variable-speed transmission is to change the value of torque and rotational speed and direction; manipulation of anization's main role is to control the transmission mechanism, transmission gear ratio to achieve the exchange, that is, to achieve shift in order to achieve variable-speed pitch. This subject, mainly for automotive six-axis mechanical transmission gear structural design, including the gear drive parts, control of part of the, etc., and the associated calculation and verification, through the design and verification,The main structure of the transmission line design standards, parts intensity reached the use requirements. Keywords: Automotive Mechanical Transmission ; Axis 6 block ; gear ratio ; gear wheel 购买后包含有 CAD 图纸和说明书,咨询 Q401339828 - III- 目录摘要································································································ I Abstract ·························································································· II 第1章绪论···················································································· 1 选题的背景及意义·&#
