前橋總成簡介

前橋總成安(an)裝在車(che)身的后半部分 用于撐(cheng)起車(che)身 包括 前橋殼(ke)、半軸、制(zhi)動器(qi)總成、差減速器(qi)總成 帶動輪胎(tai)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(che)前(qian)(qian)(qian)橋(qiao)(qiao)(qiao)主要是(shi)(shi)通(tong)過離合器變速(su)(su)箱(xiang)將(jiang)發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)機動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力減速(su)(su)并增加扭矩，再通(tong)過前(qian)(qian)(qian)橋(qiao)(qiao)(qiao)總成傳遞給(gei)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力的(de)最終輸出輪(lun)(lun)(lun)。同(tong)時，前(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)還(huan)起(qi)(qi)到(dao)(dao)轉向的(de)作(zuo)用(yong)。此外，前(qian)(qian)(qian)橋(qiao)(qiao)(qiao)還(huan)起(qi)(qi)到(dao)(dao)承(cheng)(cheng)載(zai)整(zheng)車(che)重量(liang)的(de)作(zuo)用(yong)，即車(che)身和(he)前(qian)(qian)(qian)懸(xuan)架通(tong)過連(lian)桿機構(gou)與前(qian)(qian)(qian)橋(qiao)(qiao)(qiao)總成連(lian)接，起(qi)(qi)到(dao)(dao)承(cheng)(cheng)載(zai)的(de)作(zuo)用(yong)。如(ru)(ru)(ru)果(guo)前(qian)(qian)(qian)橋(qiao)(qiao)(qiao)不是(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)，后(hou)(hou)(hou)輪(lun)(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)就(jiu)是(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)。此時除(chu)了承(cheng)(cheng)載(zai)功能外，還(huan)起(qi)(qi)到(dao)(dao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、減速(su)(su)、差速(su)(su)的(de)作(zuo)用(yong)。在四輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)情(qing)況下，通(tong)常(chang)(chang)在后(hou)(hou)(hou)輪(lun)(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)前(qian)(qian)(qian)面(mian)有一(yi)個分(fen)(fen)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)箱(xiang)。后(hou)(hou)(hou)輪(lun)(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)分(fen)(fen)為(wei)整(zheng)體(ti)橋(qiao)(qiao)(qiao)和(he)半軸(zhou)(zhou)(zhou)(zhou)。橋(qiao)(qiao)(qiao)梁采(cai)用(yong)非獨立懸(xuan)掛(gua)，如(ru)(ru)(ru)鋼板彈簧懸(xuan)掛(gua)；半軸(zhou)(zhou)(zhou)(zhou)采(cai)用(yong)獨立懸(xuan)架，如(ru)(ru)(ru)麥弗(fu)遜(xun)懸(xuan)架。前(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)和(he)后(hou)(hou)(hou)輪(lun)(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)之間有著本質的(de)區別，不僅僅是(shi)(shi)在外觀上。后(hou)(hou)(hou)輪(lun)(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)指的(de)是(shi)(shi)汽車(che)后(hou)(hou)(hou)部的(de)車(che)軸(zhou)(zhou)(zhou)(zhou)。如(ru)(ru)(ru)果(guo)車(che)輛(liang)由前(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，那么(me)后(hou)(hou)(hou)輪(lun)(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)只(zhi)是(shi)(shi)一(yi)個從(cong)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)(zhou)，只(zhi)起(qi)(qi)軸(zhou)(zhou)(zhou)(zhou)承(cheng)(cheng)的(de)作(zuo)用(yong)。相反，如(ru)(ru)(ru)果(guo)前(qian)(qian)(qian)橋(qiao)(qiao)(qiao)不是(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)，那么(me)后(hou)(hou)(hou)輪(lun)(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)就(jiu)是(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)。前(qian)(qian)(qian)軸(zhou)(zhou)(zhou)(zhou)除(chu)了承(cheng)(cheng)載(zai)功能外，還(huan)起(qi)(qi)到(dao)(dao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、減速(su)(su)和(he)差速(su)(su)器的(de)作(zuo)用(yong)。在四輪(lun)(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)情(qing)況下，通(tong)常(chang)(chang)在后(hou)(hou)(hou)輪(lun)(lun)(lun)軸(zhou)(zhou)(zhou)(zhou)前(qian)(qian)(qian)面(mian)有一(yi)個分(fen)(fen)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)箱(xiang)。
