傳動軸在我國各行業得到廣泛應用，其在汽車上的應用如何？和十字萬向節的小編簡單了解。

傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)軸是(shi)由軸管、伸縮(suo)套和萬向(xiang)(xiang)(xiang)(xiang)節(jie)組成。伸縮(suo)套能自動(dong)(dong)(dong)(dong)(dong)(dong)(dong)調(diao)節(jie)變速(su)器與(yu)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋之(zhi)間(jian)距離的(de)(de)變化(hua)。萬向(xiang)(xiang)(xiang)(xiang)節(jie)是(shi)保證(zheng)變速(su)器輸(shu)出(chu)(chu)軸與(yu)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋輸(shu)入軸兩軸線夾角的(de)(de)變化(hua)，并實現兩軸的(de)(de)等角速(su)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)。萬向(xiang)(xiang)(xiang)(xiang)節(jie)是(shi)汽車傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)軸上(shang)的(de)(de)關鍵部(bu)件。在前置(zhi)發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機后輪驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)車輛(liang)上(shang)，萬向(xiang)(xiang)(xiang)(xiang)節(jie)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)軸安裝在變速(su)器輸(shu)出(chu)(chu)軸與(yu)驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋主減速(su)器輸(shu)入軸之(zhi)間(jian)；而前置(zhi)發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機前輪驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)車輛(liang)省略(lve)了傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)軸，萬向(xiang)(xiang)(xiang)(xiang)節(jie)安裝在既負責驅(qu)(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)又(you)負責轉(zhuan)向(xiang)(xiang)(xiang)(xiang)的(de)(de)前橋半軸與(yu)車輪之(zhi)間(jian)。

汽車(che)是一(yi)個(ge)(ge)(ge)運動的物(wu)體。在后驅動汽車(che)上，發動機、離合器(qi)與變(bian)速器(qi)作(zuo)為一(yi)個(ge)(ge)(ge)整體安裝在車(che)架(jia)上，而(er)驅動橋通過(guo)彈性懸(xuan)掛與車(che)架(jia)連接，兩者(zhe)之間(jian)有一(yi)個(ge)(ge)(ge)距(ju)離，需要進行連接。汽車(che)運行中路面不平產(chan)生(sheng)跳動，負(fu)荷變(bian)化或(huo)者(zhe)兩個(ge)(ge)(ge)總成(cheng)安裝位置差(cha)異，都會(hui)使得變(bian)速器(qi)輸出軸(zhou)與驅動橋主減速器(qi)輸入軸(zhou)之間(jian)的夾角和(he)距(ju)離發生(sheng)變(bian)化，因(yin)此要用(yong)一(yi)個(ge)(ge)(ge)“以(yi)變(bian)應(ying)變(bian)”的裝置來解決這一(yi)個(ge)(ge)(ge)問題，因(yin)此就有了萬向節(jie)。
