前橋總成簡介

前橋(qiao)總成(cheng)安裝在車(che)身的(de)后半(ban)部(bu)分 用于撐(cheng)起車(che)身 包(bao)括 前橋(qiao)殼、半(ban)軸、制動(dong)器(qi)總成(cheng)、差減速器(qi)總成(cheng) 帶動(dong)輪胎(tai)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

汽車(che)前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)主要(yao)是(shi)(shi)通(tong)過離合(he)器(qi)(qi)變速(su)(su)箱將(jiang)發動(dong)(dong)(dong)(dong)機動(dong)(dong)(dong)(dong)力(li)減(jian)速(su)(su)并增加扭矩，再通(tong)過前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)總成傳遞給動(dong)(dong)(dong)(dong)力(li)的(de)(de)最終(zhong)輸出(chu)輪(lun)(lun)。同時(shi)，前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)(zhou)還(huan)起(qi)到(dao)(dao)轉(zhuan)向(xiang)的(de)(de)作(zuo)用(yong)。此(ci)(ci)外，前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)還(huan)起(qi)到(dao)(dao)承(cheng)(cheng)載(zai)整車(che)重量的(de)(de)作(zuo)用(yong)，即(ji)車(che)身和(he)(he)前(qian)(qian)(qian)(qian)(qian)懸架通(tong)過連桿機構與前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)總成連接，起(qi)到(dao)(dao)承(cheng)(cheng)載(zai)的(de)(de)作(zuo)用(yong)。如(ru)(ru)(ru)果前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)不(bu)(bu)是(shi)(shi)驅動(dong)(dong)(dong)(dong)橋(qiao)(qiao)，后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)就是(shi)(shi)驅動(dong)(dong)(dong)(dong)橋(qiao)(qiao)。此(ci)(ci)時(shi)除了(le)承(cheng)(cheng)載(zai)功(gong)能外，還(huan)起(qi)到(dao)(dao)驅動(dong)(dong)(dong)(dong)、減(jian)速(su)(su)、差(cha)速(su)(su)的(de)(de)作(zuo)用(yong)。在四輪(lun)(lun)驅動(dong)(dong)(dong)(dong)的(de)(de)情況下(xia)，通(tong)常在后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面有一個分動(dong)(dong)(dong)(dong)箱。后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)分為整體橋(qiao)(qiao)和(he)(he)半軸(zhou)(zhou)(zhou)(zhou)(zhou)。橋(qiao)(qiao)梁采用(yong)非獨立懸掛，如(ru)(ru)(ru)鋼板(ban)彈簧懸掛；半軸(zhou)(zhou)(zhou)(zhou)(zhou)采用(yong)獨立懸架，如(ru)(ru)(ru)麥弗遜(xun)懸架。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)(zhou)和(he)(he)后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)之間有著本(ben)質的(de)(de)區別，不(bu)(bu)僅僅是(shi)(shi)在外觀上。后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)指的(de)(de)是(shi)(shi)汽車(che)后(hou)(hou)(hou)部的(de)(de)車(che)軸(zhou)(zhou)(zhou)(zhou)(zhou)。如(ru)(ru)(ru)果車(che)輛由前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)(zhou)驅動(dong)(dong)(dong)(dong)，那(nei)么后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)只是(shi)(shi)一個從(cong)動(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)(zhou)(zhou)，只起(qi)軸(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)(cheng)的(de)(de)作(zuo)用(yong)。相反(fan)，如(ru)(ru)(ru)果前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)不(bu)(bu)是(shi)(shi)驅動(dong)(dong)(dong)(dong)橋(qiao)(qiao)，那(nei)么后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)就是(shi)(shi)驅動(dong)(dong)(dong)(dong)橋(qiao)(qiao)。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)(zhou)除了(le)承(cheng)(cheng)載(zai)功(gong)能外，還(huan)起(qi)到(dao)(dao)驅動(dong)(dong)(dong)(dong)、減(jian)速(su)(su)和(he)(he)差(cha)速(su)(su)器(qi)(qi)的(de)(de)作(zuo)用(yong)。在四輪(lun)(lun)驅動(dong)(dong)(dong)(dong)的(de)(de)情況下(xia)，通(tong)常在后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面有一個分動(dong)(dong)(dong)(dong)箱。
