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、將橋殼下部的(de)放油(you)螺塞(sai)擰下，放出(chu)橋殼的(de)潤滑油(you)；拆下主動錐齒輪(lun)凸緣與傳動軸的(de)連接螺栓；

2、半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)的拆卸(xie)(xie)。拆卸(xie)(xie)前，應(ying)將(jiang)前輪用(yong)(yong)掩木(mu)掩住(zhu)(zhu)，松開(kai)駐(zhu)車制動(dong)器。拆卸(xie)(xie)時，松開(kai)并(bing)擰下全部半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)緊固螺母及墊圈；用(yong)(yong)銅(tong)錘(chui)輕輕打擊(ji)半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)尾(wei)部中央2至(zhi)3下，使(shi)(shi)半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)法蘭面(mian)與輪轂連接面(mian)分離后(hou)，用(yong)(yong)手拉半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)法蘭，即(ji)可將(jiang)半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)抽出。注(zhu)意在半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)花鍵部分即(ji)將(jiang)通過油(you)封時，要用(yong)(yong)手托住(zhu)(zhu)半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)桿部，并(bing)緩(huan)緩(huan)轉動(dong)半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)，使(shi)(shi)半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)并(bing)行(xing)移出，不致將(jiang)半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)油(you)封損(sun)壞，也預防半(ban)(ban)(ban)(ban)(ban)(ban)軸(zhou)(zhou)掉地扎傷人；

3、主減(jian)速器(qi)(qi)總成的(de)(de)拆(chai)卸(xie)：卸(xie)下(xia)后制(zhi)動軟管(guan)與(yu)三通接頭；用(yong)小車，將(jiang)減(jian)速器(qi)(qi)殼支承好，拆(chai)下(xia)減(jian)速器(qi)(qi)殼與(yu)后橋(qiao)連接的(de)(de)12個螺(luo)栓，將(jiang)減(jian)速器(qi)(qi)總成從橋(qiao)殼上取下(xia)；斷開制(zhi)動氣室軟管(guan)、管(guan)路之間(jian)的(de)(de)連接，拆(chai)下(xia)制(zhi)動氣室，拆(chai)下(xia)調整臂總成；

4、拆除輪(lun)轂(gu)(gu)調整螺母(mu)(mu)鎖(suo)片緊固(gu)螺釘(ding)，取出鎖(suo)片用，專用套筒拆掉輪(lun)轂(gu)(gu)調整螺母(mu)(mu)；稍稍轉動(dong)(dong)(dong)輪(lun)轂(gu)(gu)及制(zhi)動(dong)(dong)(dong)鼓總成，用拉馬向外拉輪(lun)轂(gu)(gu)，同(tong)時(shi)(shi)在制(zhi)動(dong)(dong)(dong)鼓上輕(qing)輕(qing)敲擊，以震松外軸承(cheng)內(nei)(nei)圈，待外軸承(cheng)內(nei)(nei)圈松動(dong)(dong)(dong)后(hou)，取下輪(lun)轂(gu)(gu)及制(zhi)動(dong)(dong)(dong)鼓總成，但此時(shi)(shi)應注意(yi)(yi)該總成重(zhong)量較重(zhong)，不要(yao)摔壞(huai)或砸傷人，同(tong)時(shi)(shi)要(yao)注意(yi)(yi)保護外軸承(cheng)內(nei)(nei)圈不要(yao)摔壞(huai)；

5、用(yong)(yong)拉(la)馬(ma)拆(chai)出內軸(zhou)承內圈總成和(he)油封座圈總成；用(yong)(yong)回位彈簧(huang)拆(chai)卸工具，拆(chai)下制(zhi)(zhi)(zhi)動器回位彈簧(huang)，取下凸輪(lun)軸(zhou)；用(yong)(yong)板(ban)手(shou)拆(chai)下制(zhi)(zhi)(zhi)動器底板(ban)緊固(gu)螺栓，取下制(zhi)(zhi)(zhi)動器底板(ban)帶蹄片及防塵罩總成；拆(chai)下制(zhi)(zhi)(zhi)動氣(qi)室支架，拆(chai)下橋(qiao)殼(ke)總成；

6、最(zui)后安裝拆卸的(de)反序安裝即可(ke)。
