It is also an assembly which is used for automotive transmission lines connected directly to the engine. Now many kinds of the automotive adopt the friction clutch which is a device separation relies on the primary, and driven to deliver the friction between the parts and can power It mainly includes four parts: driving part??, driven part?, hold-down mechanism and control mechanism. Its function as: the car a smooth start, to interrupt the transmission of power to meet the shift, to prevent transmission of the overload. In recent years theca spring clutch is a kind of clutch that widely adopted in vehicle. It has great capacity of torque And more stable, manipulate easy and convenient, well equilibrium, And also can produce batch .so the research of the clutch is more and more important . This design manual elaborated on the construction form, parametre choose and process of calculate of the passenger car. This article is passenger cars diaphragm spring clutch design.. According to traffic conditions and vehicle parameters, in accordance with the clutch system of steps and requirements, mainly for the following work：Select the design for the main parameters: the determination of friction-diameter, the determining factor clutch reserve, the pressure on the units identified . And the design of the main assembly: the separation device design, set design and follower (the hub-driven design) and cylindrical coil spring design, and so on. Key words: passenger cars; clutch; diaphragm spring; friction disc 目錄 1概述------------------------------------------------------------------------------------------1 2 離合總體方案的初定--------------------------------------------------------------------1 2.1確定所選發(fā)動(dòng)機(jī)的基本參數(shù)---------------------------------------------------------1 2.2結(jié)構(gòu)設(shè)計(jì)---------------------------------------------------------------------------------2 3 離合器基本結(jié)構(gòu)參數(shù)的確定-----------------------------------------------------------5 3.1離合器后備系數(shù)的確定------------------------------------------------------------5 3.2單位壓力P的確定---------------------------------------------------------------------5 3.3 摩擦片外徑及其它尺寸的確定-----------------------------------------------------6 4 離合器膜片彈簧的設(shè)計(jì)-----------------------------------------------------------------7 4.1 膜片彈簧的作用方式選擇及工作過程--------------------------------------------7 4.2膜片彈簧的彈性變形特性及其工作------------------------------------------------7 4.3 膜片彈簧的參數(shù)尺寸及材料的確定-----------------------------------------------7 4.4 膜片彈簧的計(jì)算-----------------------------------------------------------------------9 5 扭轉(zhuǎn)減振器簡單設(shè)計(jì)-------------------------------------------------------------------10 5.1 扭轉(zhuǎn)減振器的結(jié)構(gòu)和工作原理----------------------------------------------------10 5.2 減振彈簧的參數(shù)設(shè)計(jì)------------------------------------------------------------ --11 6 離合器從動(dòng)盤總成設(shè)計(jì)----------------------------------------------------------------13 6.1從動(dòng)盤結(jié)構(gòu)及工作原理--------------------------------------------------------------13 6.2 從動(dòng)盤設(shè)計(jì)要求----------------------------------------------------------------------14 6.3 軸向彈性從動(dòng)盤的結(jié)構(gòu)形式選擇-------------------------------------------------14 6.4從動(dòng)盤轂的設(shè)計(jì)-----------------------------------------------------------------------14 6.5摩擦片的選取--------------------------------------------------------------------------16 7 離合器蓋總成設(shè)計(jì)----------------------------------------------------------------------17 7.1離合器蓋設(shè)計(jì)------------------------------------------------------------------------- 17 7.2壓盤及傳動(dòng)片設(shè)計(jì)--------------------------------------------------------------------17 7.3分離杠桿裝置設(shè)計(jì)--------------------------------------------------------------------19 7.4支撐環(huán)設(shè)計(jì)-----------------------------------------------------------------------------19 8 分離軸承總成及離合器殼體的設(shè)計(jì)-------------------------------------------------19 8.1分離軸承總成設(shè)計(jì)--------------------------------------------------------------------19 8.2離合器殼的設(shè)計(jì)-----------------------------------------------------------------------20 9 結(jié)論---------------------------------------------------------------------------------------
