前橋總成簡介

前橋(qiao)總成(cheng)安(an)裝在車身(shen)的后(hou)半部分 用于撐(cheng)起(qi)車身(shen) 包括 前橋(qiao)殼、半軸(zhou)、制動(dong)器(qi)總成(cheng)、差(cha)減速器(qi)總成(cheng) 帶動(dong)輪(lun)胎的運轉。

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(qi)車(che)(che)(che)前(qian)(qian)(qian)(qian)橋(qiao)主要是(shi)通(tong)過(guo)離(li)合器變(bian)速(su)箱(xiang)將發動(dong)(dong)(dong)機動(dong)(dong)(dong)力減(jian)速(su)并增加(jia)扭矩，再(zai)通(tong)過(guo)前(qian)(qian)(qian)(qian)橋(qiao)總(zong)成(cheng)傳遞(di)給動(dong)(dong)(dong)力的(de)(de)(de)最終輸出輪(lun)(lun)。同(tong)時，前(qian)(qian)(qian)(qian)軸(zhou)還(huan)起到轉向的(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)(yong)。此(ci)外，前(qian)(qian)(qian)(qian)橋(qiao)還(huan)起到承(cheng)(cheng)載(zai)整車(che)(che)(che)重量的(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)(yong)，即車(che)(che)(che)身(shen)和(he)前(qian)(qian)(qian)(qian)懸架(jia)(jia)通(tong)過(guo)連桿機構與前(qian)(qian)(qian)(qian)橋(qiao)總(zong)成(cheng)連接，起到承(cheng)(cheng)載(zai)的(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)(yong)。如(ru)(ru)果前(qian)(qian)(qian)(qian)橋(qiao)不(bu)(bu)是(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)，后(hou)輪(lun)(lun)軸(zhou)就是(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)。此(ci)時除了(le)(le)承(cheng)(cheng)載(zai)功(gong)能(neng)外，還(huan)起到驅(qu)(qu)(qu)動(dong)(dong)(dong)、減(jian)速(su)、差(cha)速(su)的(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)(yong)。在四(si)輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)(de)情(qing)(qing)況下，通(tong)常(chang)在后(hou)輪(lun)(lun)軸(zhou)前(qian)(qian)(qian)(qian)面有(you)(you)一(yi)個(ge)分(fen)動(dong)(dong)(dong)箱(xiang)。后(hou)輪(lun)(lun)軸(zhou)分(fen)為整體(ti)橋(qiao)和(he)半軸(zhou)。橋(qiao)梁采用(yong)(yong)(yong)(yong)(yong)非獨立懸掛(gua)，如(ru)(ru)鋼板彈簧懸掛(gua)；半軸(zhou)采用(yong)(yong)(yong)(yong)(yong)獨立懸架(jia)(jia)，如(ru)(ru)麥(mai)弗遜懸架(jia)(jia)。前(qian)(qian)(qian)(qian)軸(zhou)和(he)后(hou)輪(lun)(lun)軸(zhou)之(zhi)間有(you)(you)著本質的(de)(de)(de)區別，不(bu)(bu)僅僅是(shi)在外觀上。后(hou)輪(lun)(lun)軸(zhou)指的(de)(de)(de)是(shi)汽(qi)車(che)(che)(che)后(hou)部(bu)的(de)(de)(de)車(che)(che)(che)軸(zhou)。如(ru)(ru)果車(che)(che)(che)輛由前(qian)(qian)(qian)(qian)軸(zhou)驅(qu)(qu)(qu)動(dong)(dong)(dong)，那么后(hou)輪(lun)(lun)軸(zhou)只是(shi)一(yi)個(ge)從動(dong)(dong)(dong)軸(zhou)，只起軸(zhou)承(cheng)(cheng)的(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)(yong)。相反，如(ru)(ru)果前(qian)(qian)(qian)(qian)橋(qiao)不(bu)(bu)是(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)，那么后(hou)輪(lun)(lun)軸(zhou)就是(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)。前(qian)(qian)(qian)(qian)軸(zhou)除了(le)(le)承(cheng)(cheng)載(zai)功(gong)能(neng)外，還(huan)起到驅(qu)(qu)(qu)動(dong)(dong)(dong)、減(jian)速(su)和(he)差(cha)速(su)器的(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)(yong)。在四(si)輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)(de)情(qing)(qing)況下，通(tong)常(chang)在后(hou)輪(lun)(lun)軸(zhou)前(qian)(qian)(qian)(qian)面有(you)(you)一(yi)個(ge)分(fen)動(dong)(dong)(dong)箱(xiang)。
