傳動軸介紹中英文對照

-!專業(yè)英語實訓(xùn)報告班級：094022學(xué)號：09402213姓名：劉軍-!傳動軸各式各樣的傳動軸傳動軸是一個高轉(zhuǎn)速、少支承的旋轉(zhuǎn)體，因此它的動平衡是至關(guān)重要的。一般傳動軸在出廠前都要進行動平衡試驗，并在平衡機上進行了調(diào)整。對前置引擎后輪驅(qū)動的車來說是把變速器的轉(zhuǎn)動傳到主減速器的軸，它可以是好幾節(jié)的，節(jié)與節(jié)之間可以由萬向節(jié)連接。謝謝閱讀一.簡介傳動軸是由軸管、伸縮套和萬向節(jié)組成。傳動軸(DriveShaft)連接或裝配各項配精品文檔放心下載件，而又可移動或轉(zhuǎn)動的圓形物體配件，一般均使用輕而抗扭性佳的合金鋼管制成。對前置引擎后輪驅(qū)動的車來說是把變速器的轉(zhuǎn)動傳到主減速器的軸，它可以是好幾節(jié)由萬向節(jié)連接。它是一個高轉(zhuǎn)速、少支承的旋轉(zhuǎn)體，因此它的動平衡是至關(guān)重要的。一般傳動軸在出廠前都要進行動平衡試驗，并在平衡機上進行了調(diào)整。謝謝閱讀二.結(jié)構(gòu)-!傳動軸是由軸管、伸縮套和萬向節(jié)組成。伸縮套能自動調(diào)節(jié)變速器與驅(qū)動橋之間感謝閱讀距離的變化。萬向節(jié)是保證變速器輸出軸與驅(qū)動橋輸入軸兩軸線夾角的變化，并實現(xiàn)兩軸的等角速傳動。精品文檔放心下載萬向節(jié)1.作用：一般萬向節(jié)由十字軸、十字軸承和凸緣叉等組成。萬向節(jié)是汽車傳動軸上的關(guān)鍵部件。在前置發(fā)動機后輪驅(qū)動的車輛上，萬向節(jié)傳動軸安裝在變速器輸出軸與驅(qū)動橋主減速器輸入軸之間；而前置發(fā)動機前輪驅(qū)動的車輛省略了傳動軸，萬向節(jié)安裝在既負責驅(qū)動又負責轉(zhuǎn)向的前橋半軸與車輪之間。車輛在運行中路面不平產(chǎn)生跳動，負荷變化或者兩個總成安裝位置差異，都會使得變速器輸出軸與驅(qū)動橋主減速器輸入軸之間的夾角和距離發(fā)生變化，因此要用一個“以變應(yīng)變”的裝置來解決這一個問題，因此就有了萬向節(jié)。精品文檔放心下載2.傳動特點：在發(fā)動機前置后輪驅(qū)動（或全輪驅(qū)動）的汽車上，由于汽車在運動過程中懸架變形，驅(qū)動軸主減速器輸入軸與變速器（或分動箱）輸出軸間經(jīng)常有相對運動，此外，為有效避開某些機構(gòu)或裝置（無法實現(xiàn)直線傳遞），必須有一種裝置來實現(xiàn)動力的正常傳遞，于是就出現(xiàn)了萬向節(jié)傳動。萬向節(jié)傳動必須具備以下特點：精品文檔放心下載a、保證所連接兩軸的相對位置在預(yù)計范圍內(nèi)變動時，能可靠地傳遞動力；b、保證所連接兩軸能均勻運轉(zhuǎn)。由于萬向節(jié)夾角而產(chǎn)生的附加載荷、振動和噪聲應(yīng)在允許范圍內(nèi)；精品文檔放心下載、傳動效率要高，使用壽命長，結(jié)構(gòu)簡單，制造方便，維修容易。對汽車而言，由于一個十字軸萬向節(jié)的輸出軸相對于輸入軸（有一定的夾角）是不等速旋轉(zhuǎn)的，為此必須采用雙萬向節(jié)（或多萬向節(jié)）傳動，并把同傳動軸相連的兩個萬向節(jié)叉布置在同一平面，且使兩萬向節(jié)的夾角相等。這一點是十分重要的。在設(shè)計時應(yīng)盡量減小萬向節(jié)的夾角。謝謝閱讀伸縮套傳統(tǒng)結(jié)構(gòu)的傳動軸伸縮套是將花鍵套與凸緣叉焊接在一起，將花鍵軸焊在傳動軸精品文檔放心下載管上。新型的的傳動軸一改傳統(tǒng)結(jié)構(gòu)，將花鍵套與傳動軸管焊接成一體，將花鍵軸與凸緣叉制成一體。并將矩形齒花鍵改成大壓力角漸開線短齒花鍵，這樣既增加了強度謝謝閱讀-!又便于擠壓成形，適應(yīng)大轉(zhuǎn)矩工況的需要。在伸縮套管和花鍵軸的牙齒表面，整體涂浸了一層尼龍材料，不僅增加了耐磨性和自潤滑性，而且減少了沖擊負荷對傳動軸的損害，提高了緩沖能力。精品文檔放心下載此種傳動軸在凸緣花鍵軸外增加了一個管形密封保護套，在該保護套端部設(shè)置了兩道聚氨酯橡膠油封，使伸縮套內(nèi)形成廠一個完全密封的空間，使伸縮花鍵軸不受外界沙塵的侵蝕，不僅防塵而且防銹。因此在裝配時在花鍵軸與套內(nèi)一次性涂抹潤滑脂，就完全可以滿足使用要求，不需要裝油嘴潤滑，減少了保養(yǎng)內(nèi)容。謝謝閱讀軸套是為了減少軸運動時的摩擦與磨損而設(shè)計出來的，基本用途與軸承無異，而且相對成本較便宜，但摩擦阻力較大，所以只會使用于部份部件上。軸套大多都以銅制成，但亦有塑膠制的軸套。軸套多被放置于軸與承托結(jié)構(gòu)中，而且非常緊貼承托結(jié)構(gòu)，只有軸能在軸套上轉(zhuǎn)動。在裝配軸與軸套時，兩者間會加入潤滑劑以減少其轉(zhuǎn)動時產(chǎn)生的摩擦力。精品文檔放心下載三.類型按彈性分傳動軸按其重要部件--萬向節(jié)的不同，可有不同的分類。如果按萬向節(jié)在扭轉(zhuǎn)的方向是否有明顯的彈性可分為剛性萬向節(jié)傳動軸和撓性萬向節(jié)傳動軸。感謝閱讀1.剛性萬向節(jié)：靠零件的鉸鏈式聯(lián)接傳遞動力的。2.撓行萬向節(jié)：靠彈性零件傳遞動力，并具有緩沖減振作用。感謝閱讀按角速率分-!剛性萬向節(jié)又可分為不等速萬向節(jié)（如十字軸式萬向節(jié)）、準等速萬向節(jié)（如雙聯(lián)式萬向節(jié)、三銷軸式萬向節(jié)）和等速萬向節(jié)（如球籠式萬向節(jié)、球叉式萬向節(jié)）。等速與不等速，是指從動軸在隨著主動軸轉(zhuǎn)動時，兩者的轉(zhuǎn)動角速率是否相等而言的，當然，主動軸和從動軸的平均轉(zhuǎn)速是相等的。謝謝閱讀1.等速萬向節(jié)：主、從動軸的角速度在兩軸之間的夾角變動時仍然相等的萬向節(jié)，稱為等速萬向節(jié)或等角速萬向節(jié)。它們主要用于轉(zhuǎn)向驅(qū)動橋、斷開式驅(qū)動橋等的車輪傳動裝置中，主要用于轎車中的動力傳遞。精品文檔放心下載2.不等速萬向節(jié)：主、從動軸的角速度在兩軸之間的夾角變動時不相等的萬向節(jié)，稱為不等速萬向節(jié)，也叫做十字軸式萬向節(jié)。謝謝閱讀十字軸式剛性萬向節(jié)傳動軸在汽車傳動系中用得最廣泛，歷史也最悠久。當轎車為后輪驅(qū)動時，常采用十字軸式萬向節(jié)傳動軸，對部分高檔轎車，也有采用等速球頭的；當轎車為前輪驅(qū)動時，則常采用等速萬向節(jié)——等速萬向節(jié)也是一種傳動軸，只是稱謂不同而已。平時所說的傳動軸一般指的就是十字軸式剛性萬向節(jié)傳動軸。十字軸式剛性萬向節(jié)主要用于傳遞角度的變化，一般由突緣叉、十字軸帶滾針軸承總成、萬向節(jié)叉或滑動叉、中間連接叉或花鍵軸叉、滾針軸承的軸向固定件等組成。感謝閱讀突緣叉是一個帶法蘭的叉形零件，一般采用中碳鋼或中碳合金鋼的鍛造件，也有采用球墨鑄鐵的砂型鑄造件和中碳鋼或中碳優(yōu)質(zhì)合金鋼的精密鑄造件。突緣叉一般帶一個平法蘭，也有帶一個端面梯形齒法蘭的。十字軸帶滾針軸承總成一般包括四個滾針軸承、一個十字軸、一個滑脂嘴。滾針軸承一般由若干個滾針、一個軸承碗、一個多刃口橡膠油封（部分帶骨架）組成。在某些滾針軸承中，還有一個帶油槽的圓形墊片，有尼龍的，也有采用銅片或其他材料的，主要用于減小萬向節(jié)軸向間隙，提高傳動軸動平衡品質(zhì)。萬向節(jié)叉是一個叉形零件，一般采用中碳鋼或中碳合金鋼的鍛造件，也有采用中碳鋼的精密鑄造件。滾針軸承的軸向固定件一般是孔（或軸）用彈性擋圈（內(nèi)外卡式），或軸承壓板、鎖片、螺栓等。謝謝閱讀四.用途專用汽車傳動軸主要用在油罐車，加油車，灑水車，吸污車，吸糞車，消防車，高壓清洗車，道路清障車，高空作業(yè)車，垃圾車等車型上。感謝閱讀-!五.使用與保養(yǎng)為了確保傳動軸的正常工作，延長其使用壽命，在使用中應(yīng)注意：精品文檔放心下載1．嚴禁汽車用高速檔起步。2．嚴禁猛抬離合器踏板。3．嚴禁汽車超載、超速行駛。4．應(yīng)經(jīng)常檢查傳動軸工作狀況。5．應(yīng)經(jīng)常檢查傳動軸吊架緊固情況，支承橡膠是否損壞，傳動軸各連接部位是否松曠，傳動軸是否變形。謝謝閱讀6．為了保證傳動軸的動平衡，應(yīng)經(jīng)常注意平衡焊片是否脫焊。新傳動軸組件是配套提供的，在新傳動軸裝車時應(yīng)注意伸縮套的裝配標記，應(yīng)保證凸緣叉在一個平面內(nèi)。在維修拆卸傳動軸時，應(yīng)在伸縮套與凸緣軸上打印裝配標記，以備重新裝配時保持原裝配關(guān)系不變。感謝閱讀7．應(yīng)經(jīng)常為萬向節(jié)十字軸承加注潤滑脂，夏季應(yīng)注入3號鋰基潤滑脂，冬季注入2號鋰基潤滑脂。感謝閱讀差速器-!汽車發(fā)動機的動力經(jīng)離合器、變速器、傳動軸，最后傳送到驅(qū)動橋再左右分配給半軸驅(qū)動車輪，在這條動力傳送途徑上，驅(qū)動橋是最后一個總成，它的主要部件是減速器和差速器。感謝閱讀一.簡介減速器的作用就是減速增矩，這個功能完全靠齒輪與齒輪之間的嚙合完成，比較容易理解。而差速器就比較難理解，什么叫差速器，為什么要“差速”？汽車差速器是驅(qū)動橋的主件。它的作用就是在向兩邊半軸傳遞動力的同時，允許兩邊半軸以不同的轉(zhuǎn)速旋轉(zhuǎn)，滿足兩邊車輪盡可能以純滾動的形式作不等距行駛，減少輪胎與地面的摩擦。謝謝閱讀二.功能-!汽車在拐彎時車輪的軌線是圓弧，如果汽車向左轉(zhuǎn)彎，圓弧的中心點在左側(cè)，在相同的時間里，右側(cè)輪子走的弧線比左側(cè)輪子長，為了平衡這個差異，就要左邊輪子慢一點，右邊輪子快一點，用不同的轉(zhuǎn)速來彌補距離的差異。謝謝閱讀如果后輪軸做成一個整體，就無法做到兩側(cè)輪子的轉(zhuǎn)速差異，也就是做不到自動調(diào)整。為了解決這個問題，早在一百年前，法國雷諾汽車公司的創(chuàng)始人路易斯·雷諾就設(shè)計出了差速器這個東西。感謝閱讀三.構(gòu)成普通差速器由行星齒輪、行星輪架（差速器殼）、半軸齒輪等零件組成。發(fā)動機的動力經(jīng)傳動軸進入差速器，直接驅(qū)動行星輪架，再由行星輪帶動左、右兩條半軸，分別驅(qū)動左、右車輪。差速器的設(shè)計要求滿足：（左半軸轉(zhuǎn)速）（右半軸轉(zhuǎn)速）=2（行星輪架轉(zhuǎn)速）。當汽車直行時，左、右車輪與行星輪架三者的轉(zhuǎn)速相等處于平衡狀態(tài)，而在汽車轉(zhuǎn)彎時三者平衡狀態(tài)被破壞，導(dǎo)致內(nèi)側(cè)輪轉(zhuǎn)速減小，外側(cè)輪轉(zhuǎn)速增加。謝謝閱讀四.原理-!差速器的這種調(diào)整是自動的，這里涉及到“最小能耗原理”，也就是地球上所有物體都傾向于耗能最小的狀態(tài)。例如把一粒豆子放進一個碗內(nèi)，豆子會自動停留在碗底而絕不會停留在碗壁，因為碗底是能量最低的位置（位能），它自動選擇靜止（動能最?。┒粫粩噙\動。同樣的道理，車輪在轉(zhuǎn)彎時也會自動趨向能耗最低的狀態(tài)，自動地按照轉(zhuǎn)彎半徑調(diào)整左右輪的轉(zhuǎn)速。精品文檔放心下載當轉(zhuǎn)彎時，由于外側(cè)輪有滑拖的現(xiàn)象，內(nèi)側(cè)輪有滑轉(zhuǎn)的現(xiàn)象，兩個驅(qū)動輪此時就會產(chǎn)生兩個方向相反的附加力，由于“最小能耗原理”，必然導(dǎo)致兩邊車輪的轉(zhuǎn)速不同，從而破壞了三者的平衡關(guān)系，并通過半軸反映到半軸齒輪上，迫使行星齒輪產(chǎn)生自轉(zhuǎn)，使外側(cè)半軸轉(zhuǎn)速加快，內(nèi)側(cè)半軸轉(zhuǎn)速減慢，從而實現(xiàn)兩邊車輪轉(zhuǎn)速的差異。精品文檔放心下載驅(qū)動橋兩側(cè)的驅(qū)動輪若用一根整軸剛性連接，則兩輪只能以相同的角度旋轉(zhuǎn)。這樣，當汽車轉(zhuǎn)向行駛時，由于外側(cè)車輪要比內(nèi)側(cè)車輪移過的距離大，將使外側(cè)車輪在滾動的同時產(chǎn)生滑拖，而內(nèi)側(cè)車輪在滾動的同時產(chǎn)生滑轉(zhuǎn)。即使是汽車直線行駛，也會因路面不平或雖然路面平直但輪胎滾動半徑不等（輪胎制造誤差、磨損不同、受載不均或氣壓不等）而引起車輪的滑動。感謝閱讀車輪滑動時不僅加劇輪胎磨損、增加功率和燃料消耗，還會使汽車轉(zhuǎn)向困難、制動性能變差。為使車輪盡可能不發(fā)生滑動，在結(jié)構(gòu)上必須保證各車輪能以不同的角度轉(zhuǎn)動。感謝閱讀軸間差速器：通常從動車輪用軸承支承在主軸上，使之能以任何角度旋轉(zhuǎn)，而驅(qū)動車輪分別與兩根半軸剛性連接，在兩根半軸之間裝有差速器。這種差速器又稱為軸間差速器。感謝閱讀多軸驅(qū)動的越野汽車，為使各驅(qū)動橋能以不同角速度旋轉(zhuǎn)，以消除各橋上驅(qū)動輪的滑動，有的在兩驅(qū)動橋之間裝有軸間差速器。精品文檔放心下載-!五.差速器的檢修1．差速器殼不能有任何性質(zhì)的裂紋，殼體與行星齒輪墊片,差速器半軸齒輪之間的接觸，應(yīng)光滑無溝槽；若有輕微溝槽或磨損,可修磨后繼續(xù)使用，否則應(yīng)予更換或予以修理。謝謝閱讀2．差速器殼上行星齒輪軸孔與行星齒輪輪軸的配合間隙不得大于0.1-0.15mm,半軸齒輪軸頸與殼孔的配合為間隙配合，應(yīng)無明顯松精品文檔放心下載曠感覺,否則應(yīng)予更換或修理。半軸半軸（DriverShaft）也叫驅(qū)動軸（CVJ）。半軸是變速箱減速器與驅(qū)動輪之間傳遞扭矩的軸，其內(nèi)外端各有一個萬向節(jié)（U/JOINT)分別通過萬向節(jié)上的花鍵與減速器齒輪及輪轂軸承內(nèi)圈連接。謝謝閱讀半軸（DriverShaft）也叫驅(qū)動軸（CVJ）。謝謝閱讀半軸是變速箱減速器與驅(qū)動輪之間傳扭矩的軸（以前實心居多，但由于空心軸轉(zhuǎn)動不平衡控制更容易，因此，很多轎車上都采用空心軸），其內(nèi)外端各有一個萬向節(jié)（U/JOINT)分別通過萬向節(jié)上的花鍵與減速器齒輪及輪轂軸承內(nèi)圈連接。精品文檔放心下載現(xiàn)代汽車常用的半軸，根據(jù)其支承型式不同，有全浮式和半浮式兩種：謝謝閱讀-!全浮式半軸只傳遞轉(zhuǎn)矩，不承受任何反力和彎矩，與獨立懸掛配合有利于提高車輛的舒適性，因而廣泛應(yīng)用于各類汽車上。全浮式半軸易于拆裝，維修保養(yǎng)時只需擰下半軸的固定螺栓即可抽出半軸，而車輪與橋殼照樣能支持汽車，從而給汽車維護帶來方便。感謝閱讀半浮式半軸既傳遞扭矩又承受全部反力和彎矩。它的支承結(jié)構(gòu)簡單、成本低，主要適用在對舒適型要求不高的皮卡及SUV車輛上。但這種半軸支承拆取麻煩，且汽車行駛中若半軸折斷則易造成車輪飛脫的危險，屬于即將淘汰的形式。謝謝閱讀TransmissionshaftAwiderangeofdriveshaftdriveshaftisahigh-speed,lesssupportrotation,soit'sdynamicbalanceiscrucial.Generaldriveshaftshouldbecarriedoutatthefactorydynamicbalancetest,andwereadjustedonthebalancingmachine.Thefront-enginerear-wheeldrivecaristherotationofthetransmissionreachedthefinaldriveshaft,whichcanbeseveralsections,connectedbyuniversaljointsbetweentheFestivalandtheFestival.謝謝閱讀I.IntroductionThedriveshaftistheshafttube,telescopicuniversaljoin.Thedriveshaft(DriveShaft,)orassemblyofthevariousaccessoriesandaremovableor感謝閱讀rotatingcircularobjectparts,generallylightandtorsionresistanceofalloysteelcontrol.Thefront-enginerear-wheeldrivecaristherotationofthetransmissionreachedthefinaldriveshaft,whichcanbeseveralsectionsconnectedbyuniversaljoints.Itisahighspeedrotatingbody,andlesssupport,sothatit'sdynamicbalanceiscrucial.Generaldriveshaftshouldbecarriedoutatthefactorydynamicbalancetest,andwereadjustedonthebalancingmachine.精品文檔放心下載II.StructureThedriveshaftistheshafttube,telescopicuniversaljoint.Thetelescopicautomaticallyadjustthedistancebetweenthetransmissionanddriveaxle.Theuniversaljointistoensurethatthechangeofthetransmissionoutputshaftanddriveaxleinputshaftaxisangle,andtwoaxesoftheisometricspeedtransmission.精品文檔放心下載Universaljointrole:generaluniversaljointcrossshaftcrossbearingsandflangeforkcomponents.Theuniversaljointisakeycomponentofautomotivetransmission.Onthefrontenginerear-wheeldrivevehicles,shaftsinstalledinbetweenthetransmissionoutputshaftanddriveaxlemaingearboxinputshaft;frontenginefront-wheeldrivevehicleisomitted,thedriveshaft,universaljointinstallationresponsibleforboththedriverisalsoresponsibleforsteeringthefrontaxleaxlebetweenthewheels.Vehiclerunningroadsurfaceroughnessgeneratedbeat,changesinloadortwoassemblyinstallationlocationdifferenceswillmaketheangleanddistancebetweenthetransmissionoutputshaftanddriveaxlemaingearboxinputshaftchange,souseavariablestrain"ofthedevicetosolvethisproblem,sotherewillbeauniversaljoint.感謝閱讀Transmissioncharacteristics:inthefrontenginerear-wheeldrive(orall-wheeldrive)car,carsuspensiondeformationprocessinmotion,driveshaftmaingearboxinputshaftandthetransmissionoutputshaft(ortransfercase)oftenhaverelativemotion,Inaddition,toeffectivelyavoidcertaininstitutionsordevice(cannotachieveastraightlinepassing),theremustbeadevicetothenormaltransferofpowertoachieve,soitwasauniversaljointdrive.UniversalJointsmusthavethefollowingcharacteristics:感謝閱讀toensuretherelativepositionofconnectingthetwoaxesintheexpectedrangeofchangescanbereliablydeliverpower;bguaranteethatconnectthetwoaxesareuniformoperation.Additionalload,vibrationandnoiseduetothegimbalangleshouldbewithintheallowablerange;謝謝閱讀Toensurethatthechangesoftherelativepositionwithintheexpectedrangeconnectingthetwoaxes,reliabledeliveryofpower.謝謝閱讀Ensurethatconnectingthetwoaxescanevenoperate.Additionalload,vibrationandnoiseduetothegimbalangleshouldbewithintheallowablerange.謝謝閱讀Transmissionefficiency,longlife,simplestructure,andtheconvenienceandeasymaintenance.Thecar,theoutputshaftofacrossshaftuniversaljointrelativetotheinputshaft(theangle)isthetransmissionofconstantspeedrotation,thismustbetheuniversaljoint(orgimbal)andtwoyokesconnectedwiththedriveshaftisarrangedinthesameplane,andtwentythousandtothesectionangleequal.Thisisveryimportant.Shouldbedesignedtominimizetheangleofthegimbal.感謝閱讀TelescopicThetraditionalstructureofthedriveshafttelescopicsplinedsleeveandflangeforkweldedtogether,thesplinedshaftweldedtothed
