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、將橋殼下部的放油螺塞擰(ning)下，放出橋殼的潤滑油；拆下主動錐齒(chi)輪凸緣與傳動軸的連(lian)接螺栓；

2、半(ban)(ban)(ban)(ban)(ban)軸(zhou)的拆(chai)(chai)卸。拆(chai)(chai)卸前(qian)，應將(jiang)前(qian)輪(lun)用(yong)(yong)掩木掩住，松開駐車制動器。拆(chai)(chai)卸時，松開并擰下全部半(ban)(ban)(ban)(ban)(ban)軸(zhou)緊固螺母及墊(dian)圈；用(yong)(yong)銅(tong)錘輕輕打(da)擊半(ban)(ban)(ban)(ban)(ban)軸(zhou)尾部中央2至3下，使(shi)(shi)半(ban)(ban)(ban)(ban)(ban)軸(zhou)法蘭(lan)面與輪(lun)轂連接面分(fen)(fen)離后，用(yong)(yong)手拉半(ban)(ban)(ban)(ban)(ban)軸(zhou)法蘭(lan)，即可將(jiang)半(ban)(ban)(ban)(ban)(ban)軸(zhou)抽出。注意(yi)在半(ban)(ban)(ban)(ban)(ban)軸(zhou)花鍵(jian)部分(fen)(fen)即將(jiang)通過油(you)封(feng)時，要用(yong)(yong)手托住半(ban)(ban)(ban)(ban)(ban)軸(zhou)桿部，并緩緩轉(zhuan)動半(ban)(ban)(ban)(ban)(ban)軸(zhou)，使(shi)(shi)半(ban)(ban)(ban)(ban)(ban)軸(zhou)并行移出，不致(zhi)將(jiang)半(ban)(ban)(ban)(ban)(ban)軸(zhou)油(you)封(feng)損壞(huai)，也(ye)預防半(ban)(ban)(ban)(ban)(ban)軸(zhou)掉地扎(zha)傷人(ren)；

3、主減(jian)速(su)器(qi)總成的拆卸：卸下后制動軟管(guan)與三通(tong)接頭；用小(xiao)車，將減(jian)速(su)器(qi)殼支承好，拆下減(jian)速(su)器(qi)殼與后橋連接的12個螺栓，將減(jian)速(su)器(qi)總成從橋殼上取下；斷開(kai)制動氣(qi)(qi)室軟管(guan)、管(guan)路之間(jian)的連接，拆下制動氣(qi)(qi)室，拆下調(diao)整臂總成；

4、拆(chai)除輪(lun)(lun)轂(gu)調(diao)整螺(luo)母鎖片緊固螺(luo)釘，取出鎖片用，專用套筒拆(chai)掉輪(lun)(lun)轂(gu)調(diao)整螺(luo)母；稍稍轉動輪(lun)(lun)轂(gu)及(ji)(ji)制動鼓(gu)總成(cheng)(cheng)，用拉馬(ma)向(xiang)外(wai)拉輪(lun)(lun)轂(gu)，同時(shi)在制動鼓(gu)上(shang)輕(qing)(qing)輕(qing)(qing)敲擊，以震(zhen)松外(wai)軸承(cheng)內(nei)圈，待(dai)外(wai)軸承(cheng)內(nei)圈松動后，取下輪(lun)(lun)轂(gu)及(ji)(ji)制動鼓(gu)總成(cheng)(cheng)，但此時(shi)應(ying)注意(yi)該總成(cheng)(cheng)重(zhong)量較重(zhong)，不(bu)(bu)要摔(shuai)(shuai)壞或砸傷人，同時(shi)要注意(yi)保護外(wai)軸承(cheng)內(nei)圈不(bu)(bu)要摔(shuai)(shuai)壞；

5、用拉馬(ma)拆(chai)(chai)出內軸承內圈總成和油封(feng)座圈總成；用回位彈簧拆(chai)(chai)卸工具(ju)，拆(chai)(chai)下制動器(qi)回位彈簧，取(qu)下凸輪軸；用板(ban)手(shou)拆(chai)(chai)下制動器(qi)底(di)板(ban)緊固螺栓，取(qu)下制動器(qi)底(di)板(ban)帶(dai)蹄片及(ji)防塵(chen)罩總成；拆(chai)(chai)下制動氣(qi)室支(zhi)架，拆(chai)(chai)下橋殼總成；

6、最后(hou)安裝(zhuang)拆(chai)卸的反序安裝(zhuang)即可。
