離合器是汽車傳動(dòng)系統(tǒng)的重要部件，它承擔(dān)著傳遞扭矩、減震和防止系統(tǒng)過載等重要的作用。而離合器一般通過螺釘安裝在發(fā)動(dòng)機(jī)與變速箱間的飛輪殼中，變速器的輸入軸即為離合器的輸出軸。汽車行駛時(shí)松開或者踩下離合器后，相應(yīng)地會(huì)令發(fā)動(dòng)機(jī)與變速器平緩地接合或者分離，從而傳遞或切斷發(fā)動(dòng)機(jī)向變速器的動(dòng)力傳輸?，F(xiàn)階段普遍應(yīng)用于各種型號(hào)汽車的是依仗主動(dòng)部分和從動(dòng)部分之間的摩擦力來傳遞動(dòng)力而且易于分離的摩擦式離合器。
本設(shè)計(jì)是針對(duì)中型載貨汽車膜片式彈簧離合器來進(jìn)行設(shè)計(jì)。根據(jù)設(shè)計(jì)任務(wù)書所給的汽車型號(hào)和參數(shù)，按照離合器設(shè)計(jì)的整體步驟和要求，先確定了基本參數(shù)，然后對(duì)相關(guān)構(gòu)件進(jìn)行設(shè)計(jì)包括主動(dòng)部分、從動(dòng)部分、壓緊機(jī)構(gòu)、操縱機(jī)構(gòu)。最后根據(jù)各零部件工況對(duì)其進(jìn)行相關(guān)校核，從而確保設(shè)計(jì)出來的離合器綜合性能指標(biāo)達(dá)到最大化。

title The Design of Diaphragm Spring Clutch for Medium-duty

Truck

Abstract
The clutch is one of the important parts of the automobile transmission system it plays a significant role to transfer powerto prevent vibration and overload system.Automobile clutch is generally assembled with screws on the flywheel shell between the engine and gearbox and the input shaft of the gearbox is the output shaft of the clutch.In the carthe clutch pedal can be released or downso that the gradual bondingand the temporarily separating of the engine and gearbox to transfer or cut off the engine to the transmission input power.At presentfriction clutch is widely used in all kinds of cars which can separate easily and depends on the friction between driving part and driven part to transfers power.
This design is basically to design diaphragm type spring clutch of the medium truckloads.According to the procedures and requirements of the clutch designthe basic parameters is the first choicesecond to parts design:driving partdriven partpressing agency and control agency.At lastanalysing the relevant respectively according to various spare parts working conditionsso as to ensure the best comprehensive performance of the clutch designed.
