前橋總成簡介

前橋(qiao)總成(cheng)安(an)裝在(zai)車身(shen)(shen)的(de)(de)后半部分 用于(yu)撐起車身(shen)(shen) 包括 前橋(qiao)殼、半軸、制動(dong)(dong)器總成(cheng)、差減速器總成(cheng) 帶動(dong)(dong)輪胎的(de)(de)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)車前(qian)(qian)橋(qiao)(qiao)(qiao)主(zhu)要是通過(guo)離合器變(bian)速(su)箱(xiang)將發動(dong)(dong)(dong)(dong)(dong)機動(dong)(dong)(dong)(dong)(dong)力(li)減速(su)并增加扭矩(ju)，再通過(guo)前(qian)(qian)橋(qiao)(qiao)(qiao)總成傳遞(di)給動(dong)(dong)(dong)(dong)(dong)力(li)的(de)(de)最終輸(shu)出輪(lun)(lun)。同時(shi)，前(qian)(qian)軸(zhou)(zhou)還(huan)(huan)(huan)起到(dao)(dao)轉向的(de)(de)作用(yong)(yong)(yong)。此外，前(qian)(qian)橋(qiao)(qiao)(qiao)還(huan)(huan)(huan)起到(dao)(dao)承(cheng)(cheng)載整車重量的(de)(de)作用(yong)(yong)(yong)，即車身和前(qian)(qian)懸(xuan)架通過(guo)連(lian)(lian)桿(gan)機構與前(qian)(qian)橋(qiao)(qiao)(qiao)總成連(lian)(lian)接(jie)，起到(dao)(dao)承(cheng)(cheng)載的(de)(de)作用(yong)(yong)(yong)。如(ru)果前(qian)(qian)橋(qiao)(qiao)(qiao)不(bu)(bu)是驅(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)，后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)就(jiu)是驅(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)。此時(shi)除(chu)了(le)承(cheng)(cheng)載功能外，還(huan)(huan)(huan)起到(dao)(dao)驅(qu)動(dong)(dong)(dong)(dong)(dong)、減速(su)、差速(su)的(de)(de)作用(yong)(yong)(yong)。在四(si)輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)情況下(xia)，通常在后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)前(qian)(qian)面(mian)(mian)有一(yi)個(ge)分動(dong)(dong)(dong)(dong)(dong)箱(xiang)。后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)分為(wei)整體橋(qiao)(qiao)(qiao)和半(ban)軸(zhou)(zhou)。橋(qiao)(qiao)(qiao)梁采用(yong)(yong)(yong)非獨立(li)懸(xuan)掛，如(ru)鋼(gang)板彈簧懸(xuan)掛；半(ban)軸(zhou)(zhou)采用(yong)(yong)(yong)獨立(li)懸(xuan)架，如(ru)麥弗(fu)遜懸(xuan)架。前(qian)(qian)軸(zhou)(zhou)和后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)之間有著(zhu)本質的(de)(de)區別，不(bu)(bu)僅僅是在外觀上。后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)指的(de)(de)是汽(qi)車后(hou)(hou)部的(de)(de)車軸(zhou)(zhou)。如(ru)果車輛由前(qian)(qian)軸(zhou)(zhou)驅(qu)動(dong)(dong)(dong)(dong)(dong)，那么后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)只是一(yi)個(ge)從動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)，只起軸(zhou)(zhou)承(cheng)(cheng)的(de)(de)作用(yong)(yong)(yong)。相反，如(ru)果前(qian)(qian)橋(qiao)(qiao)(qiao)不(bu)(bu)是驅(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)，那么后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)就(jiu)是驅(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)。前(qian)(qian)軸(zhou)(zhou)除(chu)了(le)承(cheng)(cheng)載功能外，還(huan)(huan)(huan)起到(dao)(dao)驅(qu)動(dong)(dong)(dong)(dong)(dong)、減速(su)和差速(su)器的(de)(de)作用(yong)(yong)(yong)。在四(si)輪(lun)(lun)驅(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)情況下(xia)，通常在后(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)前(qian)(qian)面(mian)(mian)有一(yi)個(ge)分動(dong)(dong)(dong)(dong)(dong)箱(xiang)。
