后橋總成簡介

后橋是指連接兩個后輪的一個橋，向后驅動車的后橋稱之為驅動橋，不是后驅車的后橋稱之為支撐橋
后懸架總成 往往出現在乘用車中，一般由彈簧、減震器、連接桿、等組成的起到傳遞和支撐輪胎和車身的之間的激勵的部件。 
一般分為三種 獨立懸架（連桿式的）、半獨立懸架（扭力梁式）、非獨立懸架（橋或者軸式的）。后橋是指連接兩個后輪的一個橋，向后驅動車的后橋稱之為驅動橋，不是后驅車的后橋稱之為支撐橋，
后懸架總成是指用來支撐車輛后部車身的，一般為獨立懸架 

后橋總成/前橋總成安裝方法

1、將橋(qiao)殼下(xia)部的放油螺塞擰下(xia)，放出橋(qiao)殼的潤滑油；拆(chai)下(xia)主動錐齒輪凸緣(yuan)與(yu)傳動軸的連接螺栓；

2、半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)的拆卸。拆卸前，應將(jiang)(jiang)前輪用(yong)(yong)掩(yan)(yan)木掩(yan)(yan)住(zhu)，松(song)開駐車(che)制(zhi)動器(qi)。拆卸時，松(song)開并擰下全(quan)部(bu)半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)緊固螺母及墊圈；用(yong)(yong)銅錘輕輕打擊半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)尾部(bu)中央2至3下，使半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)法(fa)蘭面與輪轂連接面分(fen)離后，用(yong)(yong)手(shou)(shou)拉半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)法(fa)蘭，即可將(jiang)(jiang)半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)抽出(chu)。注意(yi)在半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)花鍵部(bu)分(fen)即將(jiang)(jiang)通過油封(feng)時，要用(yong)(yong)手(shou)(shou)托住(zhu)半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)桿部(bu)，并緩(huan)緩(huan)轉動半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)，使半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)并行移出(chu)，不(bu)致將(jiang)(jiang)半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)油封(feng)損壞，也預(yu)防半(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)掉(diao)地(di)扎傷人；

3、主減(jian)速器(qi)總(zong)成的(de)拆卸(xie)：卸(xie)下(xia)后制(zhi)動(dong)軟管(guan)與(yu)三通(tong)接頭；用小車，將減(jian)速器(qi)殼(ke)(ke)(ke)支承(cheng)好，拆下(xia)減(jian)速器(qi)殼(ke)(ke)(ke)與(yu)后橋(qiao)連接的(de)12個(ge)螺(luo)栓(shuan)，將減(jian)速器(qi)總(zong)成從橋(qiao)殼(ke)(ke)(ke)上取下(xia)；斷開制(zhi)動(dong)氣室軟管(guan)、管(guan)路之間的(de)連接，拆下(xia)制(zhi)動(dong)氣室，拆下(xia)調整臂總(zong)成；

4、拆除輪(lun)轂(gu)調整螺母(mu)鎖(suo)片緊固(gu)螺釘，取出鎖(suo)片用(yong)，專用(yong)套筒拆掉輪(lun)轂(gu)調整螺母(mu)；稍(shao)稍(shao)轉(zhuan)動(dong)輪(lun)轂(gu)及制(zhi)動(dong)鼓總(zong)成(cheng)，用(yong)拉馬(ma)向外拉輪(lun)轂(gu)，同(tong)時在制(zhi)動(dong)鼓上輕(qing)輕(qing)敲擊(ji)，以震松(song)外軸(zhou)承內圈，待外軸(zhou)承內圈松(song)動(dong)后(hou)，取下輪(lun)轂(gu)及制(zhi)動(dong)鼓總(zong)成(cheng)，但此時應注(zhu)意該總(zong)成(cheng)重量較重，不要(yao)摔壞或砸傷人(ren)，同(tong)時要(yao)注(zhu)意保護外軸(zhou)承內圈不要(yao)摔壞；

5、用(yong)(yong)拉(la)馬拆(chai)出內軸承內圈總成(cheng)(cheng)(cheng)和油封(feng)座圈總成(cheng)(cheng)(cheng)；用(yong)(yong)回位彈(dan)簧(huang)拆(chai)卸工(gong)具，拆(chai)下(xia)(xia)(xia)制(zhi)動(dong)(dong)(dong)器回位彈(dan)簧(huang)，取下(xia)(xia)(xia)凸(tu)輪(lun)軸；用(yong)(yong)板(ban)(ban)手拆(chai)下(xia)(xia)(xia)制(zhi)動(dong)(dong)(dong)器底(di)板(ban)(ban)緊固(gu)螺栓，取下(xia)(xia)(xia)制(zhi)動(dong)(dong)(dong)器底(di)板(ban)(ban)帶蹄片及防塵(chen)罩總成(cheng)(cheng)(cheng)；拆(chai)下(xia)(xia)(xia)制(zhi)動(dong)(dong)(dong)氣室支(zhi)架，拆(chai)下(xia)(xia)(xia)橋殼總成(cheng)(cheng)(cheng)；

6、最后安裝拆卸的(de)反序安裝即可。

途安簡介

途(tu)(tu)安(an)是(shi)(shi)2003年誕生在大(da)(da)眾(zhong)PQ35平(ping)臺上(shang)(shang)的(de)(de)新車(che)(che)，這次進入國內(nei)市(shi)場，上(shang)(shang)海大(da)(da)眾(zhong)為其(qi)專門打(da)造(zao)了(le)MPS（多(duo)(duo)(duo)功(gong)(gong)能(neng)轎(jiao)(jiao)車(che)(che)）的(de)(de)新概念。雖然與(yu)SMPV的(de)(de)叫法不同，但(dan)它們都是(shi)(shi)誕生在轎(jiao)(jiao)車(che)(che)平(ping)臺上(shang)(shang)的(de)(de)多(duo)(duo)(duo)功(gong)(gong)能(neng)車(che)(che)型(xing)，既(ji)具備轎(jiao)(jiao)車(che)(che)的(de)(de)舒適性又有(you)MPV的(de)(de)多(duo)(duo)(duo)功(gong)(gong)能(neng)性。途(tu)(tu)安(an)Touran 的(de)(de)名稱來自(zi)于“Tour”（旅行(xing)(xing)）與(yu)“-an”（代表多(duo)(duo)(duo)用途(tu)(tu)）的(de)(de)組合，意寓它是(shi)(shi)一(yi)款強調(diao)舒適旅行(xing)(xing)（Tour）的(de)(de)多(duo)(duo)(duo)用途(tu)(tu)（-an）車(che)(che)輛。途(tu)(tu)安(an)Touran是(shi)(shi)德國大(da)(da)眾(zhong)汽(qi)車(che)(che)公(gong)司繼(ji)傳(chuan)統的(de)(de)MPV產品線之(zhi)(zhi)外(wai)開(kai)發的(de)(de)首款緊湊型(xing)多(duo)(duo)(duo)功(gong)(gong)能(neng)轎(jiao)(jiao)車(che)(che)，也是(shi)(shi)上(shang)(shang)海大(da)(da)眾(zhong)在長期醞釀之(zhi)(zhi)后推出(chu)的(de)(de)第一(yi)款多(duo)(duo)(duo)功(gong)(gong)能(neng)轎(jiao)(jiao)車(che)(che)，填補了(le)傳(chuan)統轎(jiao)(jiao)車(che)(che)和MPV之(zhi)(zhi)間(jian)的(de)(de)市(shi)場空(kong)白，開(kai)創(chuang)國內(nei)多(duo)(duo)(duo)功(gong)(gong)能(neng)轎(jiao)(jiao)車(che)(che)（MPS）時代。Touran途(tu)(tu)安(an)新一(yi)代多(duo)(duo)(duo)功(gong)(gong)能(neng)性的(de)(de)市(shi)場定位和獨(du)特(te)的(de)(de)設計(ji)亮點，使(shi)Touran途(tu)(tu)安(an)新一(yi)代在上(shang)(shang)海大(da)(da)眾(zhong)的(de)(de)產品線上(shang)(shang)具有(you)革新性意義，同時其(qi)優(you)雅的(de)(de)造(zao)型(xing)、多(duo)(duo)(duo)變的(de)(de)空(kong)間(jian)和先進的(de)(de)技術也在同級別(bie)車(che)(che)中樹立了(le)嶄新的(de)(de)標準。
