摘要
對于以內燃機為動力的汽車，離合器在機械傳動系中是作為一個獨立的總成而存在的，它是汽車傳動系中直接與發動機相連的總成。目前，各種汽車廣泛采用的摩擦離合器是一種依靠主從動部分之間的摩擦來傳遞動力且能分離的裝置。它主要包括主動部分、從動部分、壓緊機構、和操縱機構等四部分。
    離合器的功用主要的功用是切斷和實現發動機對傳動系的動力傳遞，保證汽車起步時將發動機與傳動系平順地接合，確保汽車平穩起步；在換檔時將發動機與傳動系分離，減少變速器中換檔齒輪之間的沖擊；在工作中受到較大的動載荷時，能限制傳動系所承受的最大轉矩，以防止傳動系各零件因過載而損壞；有效地降低傳動系中的振動和噪聲。
    本次設計包括離合器各零件的結構,離合器主要參數的選擇與優化,膜片彈簧的計算與優化,扭轉減振器的設計,離合器操縱機構的設計計算和相關設計圖紙,最后撰寫了說明書。對離合器設計具有一定的研究價值。

Abstract
Regarding take the internal combustion engine as the power automobile, the coupling is takes an independent unit in the mechanical power transmission to exist, it is in the automobile power transmission direct and the engine connected unit. At present, each kind of automobile widely uses the friction clutch is one kind depends upon between the main secondary part the friction to transmit the power, and can separate installment. It mainly includes the driving part, the secondary part, the compaction organization, and the control mechanism and so on four parts. Coupling's function main function is shuts off and realizes the engine to the power transmission power transmission, guarantees the automobile starts when the engine and the power transmission joins smoothly, guaranteed that the automobile starts steadily; When shifting gears separates the engine and the power transmission, reduces in the transmission gearbox between change gear's impact; Receives when the work big moves the load, can limit the biggest torque which the power transmission withstands, prevents power transmission various components because to overload damages; Reduces in the power transmission effectively the vibration and the noise. This design including the coupling various components' structure, the coupling main parameter's choice and the optimization, disk spring's computation and the optimization, the reverse shock absorber's design, the coupling control mechanism's design calculation and is related the design paper, finally has composed the instruction booklet. Has certain research value to the coupling design.
key word: The coupling, pushes the type disk spring, the structural design
