前橋總成簡介

前橋(qiao)總(zong)成(cheng)安裝(zhuang)在車身(shen)的后半(ban)部分 用于撐(cheng)起車身(shen) 包括 前橋(qiao)殼、半(ban)軸、制動(dong)器(qi)總(zong)成(cheng)、差減速(su)器(qi)總(zong)成(cheng) 帶(dai)動(dong)輪胎的運轉。

我們經常提及汽車的前橋和后橋，那你清楚前橋到底位于車的哪個部位嗎？
汽車的前橋分布在汽車的前段，它將車的前部與兩個輪胎連接起來，同時也承擔著傳遞車架與前輪之間各向作用力，以及其所產生的彎矩和轉矩的作用。汽車前橋的主要組成部分分為前軸、輪轂組合、主銷、節臂、轉向節、制動器總成、橫拉桿總成等等。
前橋對于汽車結構來說發揮著重要作用，具體如下：

1、汽車前橋不僅對車輛前端起到承載的作用，而且具有較強的相對抗對沖擊力。

2、對于車輛的轉向、制動、行走，汽車前橋也發揮了一定的作用。

前橋是車輛的重要部件，平日車主在行車時要注意不要超載行駛，以免造成損壞，同時要定期檢查和維修前橋，出現故障及時修理或更換。

前橋總成的作用

汽車(che)前(qian)(qian)(qian)橋(qiao)(qiao)主要是(shi)通(tong)(tong)過(guo)離合器變速(su)(su)箱(xiang)將發動(dong)(dong)(dong)(dong)(dong)(dong)機(ji)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)減(jian)速(su)(su)并增加扭矩，再通(tong)(tong)過(guo)前(qian)(qian)(qian)橋(qiao)(qiao)總(zong)成傳遞給動(dong)(dong)(dong)(dong)(dong)(dong)力(li)的(de)(de)(de)最(zui)終輸出(chu)輪(lun)(lun)(lun)(lun)。同時(shi)，前(qian)(qian)(qian)軸(zhou)還(huan)(huan)起(qi)到(dao)轉向的(de)(de)(de)作用(yong)(yong)。此(ci)外，前(qian)(qian)(qian)橋(qiao)(qiao)還(huan)(huan)起(qi)到(dao)承(cheng)(cheng)(cheng)載(zai)(zai)整(zheng)車(che)重量(liang)的(de)(de)(de)作用(yong)(yong)，即車(che)身和(he)(he)前(qian)(qian)(qian)懸架通(tong)(tong)過(guo)連(lian)桿機(ji)構與前(qian)(qian)(qian)橋(qiao)(qiao)總(zong)成連(lian)接，起(qi)到(dao)承(cheng)(cheng)(cheng)載(zai)(zai)的(de)(de)(de)作用(yong)(yong)。如(ru)果前(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)，后(hou)(hou)輪(lun)(lun)(lun)(lun)軸(zhou)就是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)。此(ci)時(shi)除了(le)承(cheng)(cheng)(cheng)載(zai)(zai)功(gong)能外，還(huan)(huan)起(qi)到(dao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)、減(jian)速(su)(su)、差速(su)(su)的(de)(de)(de)作用(yong)(yong)。在(zai)四輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)情況下(xia)，通(tong)(tong)常在(zai)后(hou)(hou)輪(lun)(lun)(lun)(lun)軸(zhou)前(qian)(qian)(qian)面有一個(ge)分(fen)動(dong)(dong)(dong)(dong)(dong)(dong)箱(xiang)。后(hou)(hou)輪(lun)(lun)(lun)(lun)軸(zhou)分(fen)為整(zheng)體橋(qiao)(qiao)和(he)(he)半(ban)軸(zhou)。橋(qiao)(qiao)梁(liang)采用(yong)(yong)非(fei)獨立懸掛，如(ru)鋼板彈簧懸掛；半(ban)軸(zhou)采用(yong)(yong)獨立懸架，如(ru)麥弗(fu)遜懸架。前(qian)(qian)(qian)軸(zhou)和(he)(he)后(hou)(hou)輪(lun)(lun)(lun)(lun)軸(zhou)之間有著本質的(de)(de)(de)區(qu)別，不僅僅是(shi)在(zai)外觀上(shang)。后(hou)(hou)輪(lun)(lun)(lun)(lun)軸(zhou)指的(de)(de)(de)是(shi)汽車(che)后(hou)(hou)部(bu)的(de)(de)(de)車(che)軸(zhou)。如(ru)果車(che)輛由前(qian)(qian)(qian)軸(zhou)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)，那(nei)么后(hou)(hou)輪(lun)(lun)(lun)(lun)軸(zhou)只是(shi)一個(ge)從(cong)動(dong)(dong)(dong)(dong)(dong)(dong)軸(zhou)，只起(qi)軸(zhou)承(cheng)(cheng)(cheng)的(de)(de)(de)作用(yong)(yong)。相(xiang)反，如(ru)果前(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)，那(nei)么后(hou)(hou)輪(lun)(lun)(lun)(lun)軸(zhou)就是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)。前(qian)(qian)(qian)軸(zhou)除了(le)承(cheng)(cheng)(cheng)載(zai)(zai)功(gong)能外，還(huan)(huan)起(qi)到(dao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)、減(jian)速(su)(su)和(he)(he)差速(su)(su)器的(de)(de)(de)作用(yong)(yong)。在(zai)四輪(lun)(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)情況下(xia)，通(tong)(tong)常在(zai)后(hou)(hou)輪(lun)(lun)(lun)(lun)軸(zhou)前(qian)(qian)(qian)面有一個(ge)分(fen)動(dong)(dong)(dong)(dong)(dong)(dong)箱(xiang)。
