前橋總成簡介

前橋(qiao)總(zong)成安(an)裝在車身的后半(ban)部分 用于撐(cheng)起車身 包括 前橋(qiao)殼、半(ban)軸(zhou)、制動器總(zong)成、差減速器總(zong)成 帶(dai)動輪胎的運轉。

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(qi)車(che)前(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)主要是(shi)通(tong)(tong)過離合器(qi)變速箱(xiang)將發動(dong)(dong)(dong)(dong)機(ji)動(dong)(dong)(dong)(dong)力減(jian)速并增加(jia)扭矩(ju)，再通(tong)(tong)過前(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)總(zong)成(cheng)(cheng)傳遞給動(dong)(dong)(dong)(dong)力的(de)(de)(de)最終輸出輪(lun)。同時，前(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)還(huan)起到(dao)(dao)轉(zhuan)向的(de)(de)(de)作(zuo)用(yong)(yong)(yong)。此外(wai)，前(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)還(huan)起到(dao)(dao)承(cheng)載整車(che)重量的(de)(de)(de)作(zuo)用(yong)(yong)(yong)，即車(che)身和前(qian)(qian)懸架通(tong)(tong)過連桿機(ji)構與(yu)前(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)總(zong)成(cheng)(cheng)連接，起到(dao)(dao)承(cheng)載的(de)(de)(de)作(zuo)用(yong)(yong)(yong)。如(ru)果(guo)前(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)不(bu)是(shi)驅(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)(qiao)，后(hou)(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)就是(shi)驅(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)(qiao)。此時除了(le)承(cheng)載功能外(wai)，還(huan)起到(dao)(dao)驅(qu)動(dong)(dong)(dong)(dong)、減(jian)速、差速的(de)(de)(de)作(zuo)用(yong)(yong)(yong)。在四輪(lun)驅(qu)動(dong)(dong)(dong)(dong)的(de)(de)(de)情況下，通(tong)(tong)常(chang)在后(hou)(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)前(qian)(qian)面有一(yi)個分(fen)動(dong)(dong)(dong)(dong)箱(xiang)。后(hou)(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)分(fen)為(wei)整體(ti)橋(qiao)(qiao)(qiao)(qiao)(qiao)和半軸(zhou)(zhou)(zhou)(zhou)。橋(qiao)(qiao)(qiao)(qiao)(qiao)梁采(cai)用(yong)(yong)(yong)非(fei)獨(du)(du)立(li)懸掛(gua)，如(ru)鋼板(ban)彈(dan)簧懸掛(gua)；半軸(zhou)(zhou)(zhou)(zhou)采(cai)用(yong)(yong)(yong)獨(du)(du)立(li)懸架，如(ru)麥弗遜懸架。前(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)和后(hou)(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)之(zhi)間(jian)有著本質(zhi)的(de)(de)(de)區別，不(bu)僅(jin)僅(jin)是(shi)在外(wai)觀上。后(hou)(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)指(zhi)的(de)(de)(de)是(shi)汽(qi)車(che)后(hou)(hou)部(bu)的(de)(de)(de)車(che)軸(zhou)(zhou)(zhou)(zhou)。如(ru)果(guo)車(che)輛由前(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)驅(qu)動(dong)(dong)(dong)(dong)，那么后(hou)(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)只是(shi)一(yi)個從動(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)(zhou)，只起軸(zhou)(zhou)(zhou)(zhou)承(cheng)的(de)(de)(de)作(zuo)用(yong)(yong)(yong)。相反，如(ru)果(guo)前(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)不(bu)是(shi)驅(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)(qiao)，那么后(hou)(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)就是(shi)驅(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)(qiao)。前(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)除了(le)承(cheng)載功能外(wai)，還(huan)起到(dao)(dao)驅(qu)動(dong)(dong)(dong)(dong)、減(jian)速和差速器(qi)的(de)(de)(de)作(zuo)用(yong)(yong)(yong)。在四輪(lun)驅(qu)動(dong)(dong)(dong)(dong)的(de)(de)(de)情況下，通(tong)(tong)常(chang)在后(hou)(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)前(qian)(qian)面有一(yi)個分(fen)動(dong)(dong)(dong)(dong)箱(xiang)。
