摘 要
本次設(shè)計(jì)為東風(fēng)EQ1181W型載貨汽車設(shè)計(jì)離合器。提出了雙片離合器相較于單片離合器的優(yōu)勢(shì)，并最終確定了離合器的形式為雙片離合器。方案確定后完成了離合器的相關(guān)計(jì)算。
離合器是汽車傳動(dòng)系中的重要部件，主要功用是切斷和實(shí)現(xiàn)發(fā)動(dòng)機(jī)對(duì)傳動(dòng)系的動(dòng)力傳遞，保證汽車平穩(wěn)起步，保證傳動(dòng)系統(tǒng)換擋時(shí)工作平順以及限制傳動(dòng)系統(tǒng)所承受的最大轉(zhuǎn)矩，防止傳動(dòng)系統(tǒng)過載，有效的降低傳動(dòng)系統(tǒng)中的振動(dòng)和噪聲。離合器是汽車傳動(dòng)系中的重要部件，它的構(gòu)造特性與發(fā)展和傳動(dòng)系緊密相關(guān)。
雙片離合器設(shè)計(jì)的內(nèi)容主要包括壓盤總成、從動(dòng)盤總成、螺旋彈簧三個(gè)部分。首先，對(duì)離合器各零件的參數(shù)、尺寸、材料、及結(jié)構(gòu)進(jìn)行設(shè)計(jì)，最后轉(zhuǎn)為Auto CAD工程圖。

ABSTRACT
The designing for the type of truck Dongfeng EQ1181W is to design clutch. To proposed the two-plate clutch’s advantages compared to monolithic, and ultimately determine the form of the two-plate clutch. After the plan to be the program completed, I finish the correlation calculation
The clutch is an important component of the car transmission and main function is to cut and realize engine power transmission system,ensure the smooth start,car transmission system shift work smoothly and limit when the maximum transmission system to prevent transmission torque,overload,Reducing effectively the transmission of the vibration and noise.The clutch is an important part of the automobile’s power training, its characteristic and development have close relation with the power train.
There are three main parts of the clutch design: pressure plate design, helical spring design and the driving disc design. Firstly, this paper calculates the parameters, and chooses sizes and materials for the clutch’s parts. Finally transforms the three-dimension-blueprint into Auto CAD engineering plat.
Key words: Clutch；Helical spring ；Pressure plate；Design；Calculation
