Title The design of AMT clutch cover used in passenger car Abstract The clutch is directly connected with the engine parts of automobile driving system. In this main, driven in part by friction between the transmission power. It ensure the transmission shi ft smooth and prevent the overload of the system, to ensure car body smooth start. Clutch cover assembly is an important part of the clutch, mainly by the clutch cover , the pressure plate , diaphragm spring and other components. The engine torque through it. The structure and shape are complex of load bearing member. Through the design of clutch cover, determine cover structure of AMT clutch. The main parts of the clutch cover based on a simple finite element analysis, Compared with the check result of mechanical strength, carry on mechanical optimization of the system. The system mainly included the choice of the structure , size of the pressure plate, clutch cover, diaphragm spring and other parts design. Finally, compose the 3D modeling with CATIA software and draw the clutch parts.
