Abstract
Clutch is the assembly which is directly connected with engine in the automobile power train. And its main function is to cut off or implement the power transmission in the power train. It ensured the engine and the power train perfectly smooth join together when the automobile starting up and insure the automobile smooth starting up. The clutch is disconnected the engine and the power train when the automobile stage changeover. It reduced the impact between the shift gears of the transmission. When the transmission worked by the great dynamic load, the clutch can limit the breakdown torque of the power train, to prevent the accessory of the power train damage due to overload. It effectively reduced the vibration and noise of the power train.
In this paper, based on the analysis of the Santana 2000 car parameters, on the basis of dismantle and install diaphragm spring clutch of Santana 2000 sedans and its structural analysis to redesign the sedan clutch for it makes the design of the car clutch more reasonable. First, we should be choose the structure of the car clutch reasonable. It is mainly choose the structure of the driven disk that wet or dry, the structure of pinched spring and the layout. And I make use of CAXA electronic drawing board software draw the assembly drawing of the cars Diaphragm spring clutch. Than I make sure the choice and design calculation of the clutch structure size and the basic parameters. Finally, I carry on the structure type slection of clutch parts and the design calculation. It is mainly design and checking the driven disk assembly, platen and patch of force. And I make sure diaphragm spring main parameters of the selection, design, strength check and draw the clutch detail drawing.
