前橋總成簡介

前橋總成安裝在車身(shen)的后(hou)半(ban)部分 用于撐(cheng)起車身(shen) 包括 前橋殼、半(ban)軸、制動(dong)器總成、差減(jian)速(su)器總成 帶動(dong)輪(lun)胎的運(yun)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)(che)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)主要是(shi)(shi)(shi)通(tong)(tong)過離(li)合器(qi)變速(su)箱將(jiang)發動(dong)(dong)機動(dong)(dong)力(li)減(jian)速(su)并增加扭(niu)矩，再通(tong)(tong)過前(qian)(qian)(qian)(qian)橋(qiao)(qiao)總成傳遞給動(dong)(dong)力(li)的(de)(de)最終輸出輪(lun)(lun)(lun)(lun)(lun)(lun)。同時(shi)，前(qian)(qian)(qian)(qian)軸(zhou)(zhou)還起(qi)(qi)到(dao)(dao)轉向的(de)(de)作(zuo)用(yong)(yong)(yong)。此(ci)外(wai)(wai)(wai)，前(qian)(qian)(qian)(qian)橋(qiao)(qiao)還起(qi)(qi)到(dao)(dao)承(cheng)(cheng)載整車(che)(che)重量的(de)(de)作(zuo)用(yong)(yong)(yong)，即車(che)(che)身和前(qian)(qian)(qian)(qian)懸架通(tong)(tong)過連(lian)桿機構與前(qian)(qian)(qian)(qian)橋(qiao)(qiao)總成連(lian)接，起(qi)(qi)到(dao)(dao)承(cheng)(cheng)載的(de)(de)作(zuo)用(yong)(yong)(yong)。如果(guo)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)(shi)(shi)驅(qu)動(dong)(dong)橋(qiao)(qiao)，后(hou)輪(lun)(lun)(lun)(lun)(lun)(lun)軸(zhou)(zhou)就是(shi)(shi)(shi)驅(qu)動(dong)(dong)橋(qiao)(qiao)。此(ci)時(shi)除(chu)了(le)承(cheng)(cheng)載功能外(wai)(wai)(wai)，還起(qi)(qi)到(dao)(dao)驅(qu)動(dong)(dong)、減(jian)速(su)、差速(su)的(de)(de)作(zuo)用(yong)(yong)(yong)。在(zai)四輪(lun)(lun)(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)的(de)(de)情況下，通(tong)(tong)常在(zai)后(hou)輪(lun)(lun)(lun)(lun)(lun)(lun)軸(zhou)(zhou)前(qian)(qian)(qian)(qian)面有(you)一(yi)個分(fen)動(dong)(dong)箱。后(hou)輪(lun)(lun)(lun)(lun)(lun)(lun)軸(zhou)(zhou)分(fen)為(wei)整體(ti)橋(qiao)(qiao)和半軸(zhou)(zhou)。橋(qiao)(qiao)梁采用(yong)(yong)(yong)非獨(du)立懸掛，如鋼板彈(dan)簧懸掛；半軸(zhou)(zhou)采用(yong)(yong)(yong)獨(du)立懸架，如麥(mai)弗遜懸架。前(qian)(qian)(qian)(qian)軸(zhou)(zhou)和后(hou)輪(lun)(lun)(lun)(lun)(lun)(lun)軸(zhou)(zhou)之(zhi)間有(you)著本質的(de)(de)區別，不僅(jin)僅(jin)是(shi)(shi)(shi)在(zai)外(wai)(wai)(wai)觀(guan)上(shang)。后(hou)輪(lun)(lun)(lun)(lun)(lun)(lun)軸(zhou)(zhou)指的(de)(de)是(shi)(shi)(shi)汽車(che)(che)后(hou)部的(de)(de)車(che)(che)軸(zhou)(zhou)。如果(guo)車(che)(che)輛由前(qian)(qian)(qian)(qian)軸(zhou)(zhou)驅(qu)動(dong)(dong)，那(nei)么后(hou)輪(lun)(lun)(lun)(lun)(lun)(lun)軸(zhou)(zhou)只(zhi)是(shi)(shi)(shi)一(yi)個從動(dong)(dong)軸(zhou)(zhou)，只(zhi)起(qi)(qi)軸(zhou)(zhou)承(cheng)(cheng)的(de)(de)作(zuo)用(yong)(yong)(yong)。相反，如果(guo)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)(shi)(shi)驅(qu)動(dong)(dong)橋(qiao)(qiao)，那(nei)么后(hou)輪(lun)(lun)(lun)(lun)(lun)(lun)軸(zhou)(zhou)就是(shi)(shi)(shi)驅(qu)動(dong)(dong)橋(qiao)(qiao)。前(qian)(qian)(qian)(qian)軸(zhou)(zhou)除(chu)了(le)承(cheng)(cheng)載功能外(wai)(wai)(wai)，還起(qi)(qi)到(dao)(dao)驅(qu)動(dong)(dong)、減(jian)速(su)和差速(su)器(qi)的(de)(de)作(zuo)用(yong)(yong)(yong)。在(zai)四輪(lun)(lun)(lun)(lun)(lun)(lun)驅(qu)動(dong)(dong)的(de)(de)情況下，通(tong)(tong)常在(zai)后(hou)輪(lun)(lun)(lun)(lun)(lun)(lun)軸(zhou)(zhou)前(qian)(qian)(qian)(qian)面有(you)一(yi)個分(fen)動(dong)(dong)箱。
