前橋總成簡介

前橋總成(cheng)(cheng)安裝在(zai)車(che)身(shen)的后半部分 用于(yu)撐(cheng)起車(che)身(shen) 包括(kuo) 前橋殼(ke)、半軸、制動(dong)器(qi)總成(cheng)(cheng)、差減速器(qi)總成(cheng)(cheng) 帶動(dong)輪胎的運(yun)轉(zhuan)。

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)(che)(che)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)主要是(shi)(shi)(shi)(shi)通(tong)過離合器(qi)變(bian)速(su)箱將發動(dong)(dong)(dong)機動(dong)(dong)(dong)力減速(su)并增加扭矩(ju)，再通(tong)過前(qian)(qian)(qian)(qian)橋(qiao)(qiao)總(zong)成傳遞(di)給動(dong)(dong)(dong)力的(de)(de)(de)最終輸出輪(lun)。同(tong)時(shi)(shi)，前(qian)(qian)(qian)(qian)軸還起(qi)到轉向的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)。此外(wai)(wai)，前(qian)(qian)(qian)(qian)橋(qiao)(qiao)還起(qi)到承(cheng)(cheng)載整(zheng)車(che)(che)(che)重量的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)，即(ji)車(che)(che)(che)身和(he)前(qian)(qian)(qian)(qian)懸(xuan)架通(tong)過連桿機構(gou)與前(qian)(qian)(qian)(qian)橋(qiao)(qiao)總(zong)成連接，起(qi)到承(cheng)(cheng)載的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)。如(ru)果(guo)(guo)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)，后(hou)(hou)輪(lun)軸就是(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)。此時(shi)(shi)除(chu)了承(cheng)(cheng)載功能外(wai)(wai)，還起(qi)到驅(qu)(qu)(qu)動(dong)(dong)(dong)、減速(su)、差速(su)的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)。在四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)(de)情況下，通(tong)常在后(hou)(hou)輪(lun)軸前(qian)(qian)(qian)(qian)面(mian)有一個分(fen)動(dong)(dong)(dong)箱。后(hou)(hou)輪(lun)軸分(fen)為整(zheng)體橋(qiao)(qiao)和(he)半軸。橋(qiao)(qiao)梁采用(yong)(yong)(yong)(yong)(yong)非獨立懸(xuan)掛(gua)(gua)，如(ru)鋼(gang)板彈(dan)簧懸(xuan)掛(gua)(gua)；半軸采用(yong)(yong)(yong)(yong)(yong)獨立懸(xuan)架，如(ru)麥弗遜懸(xuan)架。前(qian)(qian)(qian)(qian)軸和(he)后(hou)(hou)輪(lun)軸之間有著本質的(de)(de)(de)區別，不僅(jin)僅(jin)是(shi)(shi)(shi)(shi)在外(wai)(wai)觀上。后(hou)(hou)輪(lun)軸指的(de)(de)(de)是(shi)(shi)(shi)(shi)汽車(che)(che)(che)后(hou)(hou)部的(de)(de)(de)車(che)(che)(che)軸。如(ru)果(guo)(guo)車(che)(che)(che)輛由前(qian)(qian)(qian)(qian)軸驅(qu)(qu)(qu)動(dong)(dong)(dong)，那么后(hou)(hou)輪(lun)軸只是(shi)(shi)(shi)(shi)一個從動(dong)(dong)(dong)軸，只起(qi)軸承(cheng)(cheng)的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)。相反，如(ru)果(guo)(guo)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)，那么后(hou)(hou)輪(lun)軸就是(shi)(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)。前(qian)(qian)(qian)(qian)軸除(chu)了承(cheng)(cheng)載功能外(wai)(wai)，還起(qi)到驅(qu)(qu)(qu)動(dong)(dong)(dong)、減速(su)和(he)差速(su)器(qi)的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)。在四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)(de)情況下，通(tong)常在后(hou)(hou)輪(lun)軸前(qian)(qian)(qian)(qian)面(mian)有一個分(fen)動(dong)(dong)(dong)箱。
