前橋總成簡介

前(qian)橋總(zong)成(cheng)安(an)裝(zhuang)在車(che)身(shen)的(de)后半部分 用于撐起車(che)身(shen) 包括 前(qian)橋殼、半軸、制動(dong)器總(zong)成(cheng)、差減(jian)速器總(zong)成(cheng) 帶動(dong)輪(lun)胎的(de)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(qi)車(che)前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)主要(yao)是(shi)(shi)通過(guo)離合器變速(su)(su)(su)箱(xiang)將發動(dong)(dong)(dong)機(ji)動(dong)(dong)(dong)力減速(su)(su)(su)并增加扭矩，再(zai)通過(guo)前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)總(zong)(zong)成(cheng)傳遞給動(dong)(dong)(dong)力的最終(zhong)輸出(chu)輪(lun)(lun)。同時，前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)還(huan)起(qi)到(dao)(dao)轉(zhuan)向的作(zuo)用(yong)(yong)(yong)。此外，前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)還(huan)起(qi)到(dao)(dao)承(cheng)載整(zheng)車(che)重量(liang)的作(zuo)用(yong)(yong)(yong)，即車(che)身和(he)前(qian)(qian)(qian)(qian)(qian)懸(xuan)(xuan)架通過(guo)連(lian)桿機(ji)構與前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)總(zong)(zong)成(cheng)連(lian)接，起(qi)到(dao)(dao)承(cheng)載的作(zuo)用(yong)(yong)(yong)。如果前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)不(bu)是(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)，后(hou)(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)就是(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)。此時除了承(cheng)載功(gong)能外，還(huan)起(qi)到(dao)(dao)驅(qu)(qu)(qu)動(dong)(dong)(dong)、減速(su)(su)(su)、差(cha)(cha)速(su)(su)(su)的作(zuo)用(yong)(yong)(yong)。在四(si)輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的情況(kuang)下，通常在后(hou)(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面(mian)有(you)(you)一(yi)(yi)個(ge)分動(dong)(dong)(dong)箱(xiang)。后(hou)(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)分為整(zheng)體橋(qiao)(qiao)和(he)半(ban)(ban)軸(zhou)(zhou)(zhou)。橋(qiao)(qiao)梁采用(yong)(yong)(yong)非獨(du)立(li)懸(xuan)(xuan)掛(gua)(gua)，如鋼板(ban)彈(dan)簧懸(xuan)(xuan)掛(gua)(gua)；半(ban)(ban)軸(zhou)(zhou)(zhou)采用(yong)(yong)(yong)獨(du)立(li)懸(xuan)(xuan)架，如麥弗遜懸(xuan)(xuan)架。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)和(he)后(hou)(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)之間(jian)有(you)(you)著(zhu)本質(zhi)的區別，不(bu)僅僅是(shi)(shi)在外觀上。后(hou)(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)指的是(shi)(shi)汽(qi)車(che)后(hou)(hou)(hou)(hou)部的車(che)軸(zhou)(zhou)(zhou)。如果車(che)輛由前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)驅(qu)(qu)(qu)動(dong)(dong)(dong)，那么后(hou)(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)只是(shi)(shi)一(yi)(yi)個(ge)從動(dong)(dong)(dong)軸(zhou)(zhou)(zhou)，只起(qi)軸(zhou)(zhou)(zhou)承(cheng)的作(zuo)用(yong)(yong)(yong)。相(xiang)反，如果前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)不(bu)是(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)，那么后(hou)(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)就是(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)除了承(cheng)載功(gong)能外，還(huan)起(qi)到(dao)(dao)驅(qu)(qu)(qu)動(dong)(dong)(dong)、減速(su)(su)(su)和(he)差(cha)(cha)速(su)(su)(su)器的作(zuo)用(yong)(yong)(yong)。在四(si)輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的情況(kuang)下，通常在后(hou)(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面(mian)有(you)(you)一(yi)(yi)個(ge)分動(dong)(dong)(dong)箱(xiang)。
