毕业设计（论文）--奥迪离合器分析.docVIP

在工作中受到大的动载荷时，能限制传动系所承受的最大转矩，防止传动系各零件因过载而损坏；有效地降低传动系中的振动和噪声。 本文通过对桑塔纳2000整车参数的分析，并在拆装桑塔纳2000轿车膜片弹簧离合器及对其进行结构分析的基础上，对轿车离合器进行重新设计，使得轿车离合器设计更合理。首先对轿车离合器的结构型式进行合理选择，主要是对从动盘数及干湿式的选择、压紧弹簧的结构型式及布置和从动盘的结构型式选择，并利用CAXA电子图板软件绘制轿车膜片弹簧离合器装配图；再进行离合器的基本结构尺寸和参数的选择及计算；最后进行离合器零件的结构选型及设计计算，主要是对从动盘总成设计，压盘、传力片的设计校核，膜片弹簧主要参数的选择、设计和强度校核，并绘制离合器零件图。 The Design of the Car Clutch Student: Jin Jianping Advisor: Dr. Li Xiqin School of Mechanical and Automotive Engineering Zhejiang University of Science and Technology Abstract 　 Clutch is the assemblydirectly 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
