600_輕型貨車設(shè)計（離合器及操縱機構(gòu)與傳動軸設(shè)計）,輕型,貨車,設(shè)計,離合器,操縱,機構(gòu),傳動軸 輕型貨車設(shè)計（離合器及操縱機構(gòu)與傳動軸設(shè)計） 摘要 在這三個月的時間里，我的最重要的任務(wù)之一就是設(shè)計汽車離合器、其操縱機構(gòu)，以及傳動軸的設(shè)計。 眾所周知汽車底盤包括傳動系、行駛系和轉(zhuǎn)向系，傳動系部件包括離合器、變速器、傳動軸、驅(qū)動橋、半軸及驅(qū)動輪。在傳動系的這些部件中，離合器和變速器無疑是兩個最為重要的部件。駕駛員通過操縱離合器既可以在變速器換檔時使發(fā)動機與離合器暫時分離，也可以在汽車起步時使發(fā)動機與離合器平穩(wěn)接合。離合器的設(shè)計采用膜片彈簧壓緊機構(gòu)，液壓式操縱機構(gòu)。在國外，常采用液壓操縱機構(gòu)的離合器以減輕駕駛員的疲勞， 通過對傳動軸的傳動類型分析，對傳動方式和傳動軸進行了選型；通過對傳動軸的類型與結(jié)構(gòu)分析，選擇了傳動軸的十字軸滾針軸承的密封形式——蓋板式密封。通過對萬向節(jié)的十字軸、滾針軸承、萬向節(jié)叉的設(shè)計計算，確定了所設(shè)計車輛使用的這些部件的具體尺寸。 綜合各部分的設(shè)計及校核結(jié)果，所設(shè)計的離合器、傳動軸能滿足所設(shè)計的輕型貨車的傳動要求。 關(guān)鍵詞：離合器，傳動軸，十字軸，操縱機構(gòu) THE DESING OF A LIGHT TRUCK (THE CLUTCKAND THE MANIPULATION OF INSTITUTIONS AND SHAFT DESIGN) ABSTRACT In these two month-long time, one of my most vital duties is designs the automobile clutch ,Its control mechanism, as well as drive shaft design. The well known motor car chassis including the power transmission, the travel is and the steering system, the power transmission part including the meeting and parting Transmission gearbox, drive shaft, driving axle, rear axle and driving gear. In power transmission these parts, to Gathering and the transmission gearbox are two most important parts without doubt. The pilot through operates the coupling already to be possible in The transmission gearbox shifts gears when causes the engine and the coupling separates temporarily, also may starts when the automobile cause the engine and Coupling steady joint. The coupling design used the disk spring to contract the organization, hydraulic control organization. In overseas, often uses the hydraulic control organization the coupling by to reduce pilot's weariness. Through to the drive shaft transmission type analysis, has carried on the shaping to the type of drive and the drive shaft; Through to the drive shaft type and the structure analysis, chose the drive shaft cross axle needle bearing seal form to cover the board style seal. Through to the universal joint cross axle, the needle bearing, the universal joint sliding yoke design calculation, had determined designs these parts concrete sizes which the vehicles uses. Synthesizes each part of designs and the check result, designs the coupling, the drive shaft can satisfy skin truck which designs to use the transport vehicle the transmission request.
