【導(dǎo)讀】本次課程設(shè)計(jì)確定了離合器的基本參數(shù)及尺寸，及其約束條件。主要零部件進(jìn)行了設(shè)計(jì)計(jì)算，包括膜片彈簧、壓盤、離合器蓋、從動(dòng)盤、操縱機(jī)構(gòu)等。這一系列工作，設(shè)計(jì)出一款能滿足后備功率較大的輕型載重汽車性能需求的新型離合器。它是汽車傳動(dòng)系中直接與發(fā)動(dòng)機(jī)相連的總成。目前，各種汽車廣泛采用的摩擦離合器是一種。依靠主從動(dòng)部分之間的摩擦來(lái)傳遞動(dòng)力且能分離的裝置。矩，以防止傳動(dòng)系各零件因過(guò)載而損壞；有效地降低傳動(dòng)系中的振動(dòng)和噪聲。為單片，選擇KD=17。初選D以后，還需注意摩擦片尺寸的系列化和標(biāo)準(zhǔn)化，表2-1. 查出本車將使用單片式離合器，且離合器摩擦片外徑為296mm。選取24顆鉚釘鉚接.其鉚接位置為R1=137mm與R2=99mm，則其鉚接的平均半徑Ra=. 鉚釘材料選為15號(hào)鋼。為被鉚件中較薄板的厚度，mm；的特點(diǎn)，初步選定后備系數(shù)β。擦片的材料及質(zhì)量等因素有關(guān)。離合器使用頻繁，發(fā)動(dòng)機(jī)后備功率較小時(shí)，P0應(yīng)取小些；當(dāng)
