前橋總成簡介

前(qian)橋(qiao)總(zong)(zong)成(cheng)安裝在車(che)(che)身(shen)的后半(ban)部分(fen) 用于撐(cheng)起車(che)(che)身(shen) 包括 前(qian)橋(qiao)殼、半(ban)軸(zhou)、制(zhi)動器總(zong)(zong)成(cheng)、差減(jian)速器總(zong)(zong)成(cheng) 帶動輪胎的運轉。

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

汽車前(qian)(qian)(qian)橋(qiao)(qiao)主要是(shi)(shi)(shi)(shi)通(tong)(tong)(tong)過(guo)(guo)離合器變速(su)箱(xiang)將(jiang)發動(dong)(dong)(dong)(dong)(dong)機動(dong)(dong)(dong)(dong)(dong)力(li)減速(su)并增(zeng)加扭矩，再通(tong)(tong)(tong)過(guo)(guo)前(qian)(qian)(qian)橋(qiao)(qiao)總(zong)成(cheng)傳(chuan)遞給動(dong)(dong)(dong)(dong)(dong)力(li)的(de)(de)最終輸出輪(lun)(lun)。同(tong)時(shi)(shi)，前(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)還起到(dao)(dao)轉向(xiang)的(de)(de)作用。此(ci)(ci)外，前(qian)(qian)(qian)橋(qiao)(qiao)還起到(dao)(dao)承(cheng)(cheng)載(zai)整車重量(liang)的(de)(de)作用，即(ji)車身和前(qian)(qian)(qian)懸(xuan)架通(tong)(tong)(tong)過(guo)(guo)連桿機構與前(qian)(qian)(qian)橋(qiao)(qiao)總(zong)成(cheng)連接(jie)，起到(dao)(dao)承(cheng)(cheng)載(zai)的(de)(de)作用。如(ru)果(guo)前(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)(shi)(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)，后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)就(jiu)是(shi)(shi)(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)。此(ci)(ci)時(shi)(shi)除了承(cheng)(cheng)載(zai)功(gong)(gong)能外，還起到(dao)(dao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)、減速(su)、差(cha)速(su)的(de)(de)作用。在(zai)四輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)情況(kuang)下，通(tong)(tong)(tong)常(chang)在(zai)后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)前(qian)(qian)(qian)面有(you)一個(ge)分動(dong)(dong)(dong)(dong)(dong)箱(xiang)。后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)分為(wei)整體橋(qiao)(qiao)和半軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)。橋(qiao)(qiao)梁采(cai)用非獨立(li)懸(xuan)掛，如(ru)鋼板彈(dan)簧(huang)懸(xuan)掛；半軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)采(cai)用獨立(li)懸(xuan)架，如(ru)麥(mai)弗遜懸(xuan)架。前(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)和后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)之間有(you)著(zhu)本質(zhi)的(de)(de)區別，不僅僅是(shi)(shi)(shi)(shi)在(zai)外觀(guan)上。后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)指(zhi)的(de)(de)是(shi)(shi)(shi)(shi)汽車后(hou)(hou)部的(de)(de)車軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)。如(ru)果(guo)車輛由前(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)，那么后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)只是(shi)(shi)(shi)(shi)一個(ge)從(cong)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)，只起軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)(cheng)的(de)(de)作用。相反，如(ru)果(guo)前(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)(shi)(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)，那么后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)就(jiu)是(shi)(shi)(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)。前(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)除了承(cheng)(cheng)載(zai)功(gong)(gong)能外，還起到(dao)(dao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)、減速(su)和差(cha)速(su)器的(de)(de)作用。在(zai)四輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)情況(kuang)下，通(tong)(tong)(tong)常(chang)在(zai)后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)前(qian)(qian)(qian)面有(you)一個(ge)分動(dong)(dong)(dong)(dong)(dong)箱(xiang)。
