前橋總成簡介

前橋(qiao)總(zong)成安(an)裝在車身的后半部分 用于撐起車身 包括 前橋(qiao)殼、半軸、制動器總(zong)成、差(cha)減(jian)速器總(zong)成 帶動輪(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

汽車前橋(qiao)主要是(shi)(shi)通(tong)過(guo)離(li)合器變速箱將發動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)減速并增(zeng)加扭矩，再通(tong)過(guo)前橋(qiao)總成(cheng)傳遞給動(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)的(de)(de)(de)(de)最(zui)終輸出輪(lun)。同(tong)時，前軸(zhou)(zhou)(zhou)(zhou)還(huan)起(qi)到(dao)轉向的(de)(de)(de)(de)作用(yong)。此外，前橋(qiao)還(huan)起(qi)到(dao)承(cheng)載整車重(zhong)量的(de)(de)(de)(de)作用(yong)，即車身和(he)前懸(xuan)架(jia)通(tong)過(guo)連桿機(ji)(ji)構與前橋(qiao)總成(cheng)連接，起(qi)到(dao)承(cheng)載的(de)(de)(de)(de)作用(yong)。如(ru)(ru)果前橋(qiao)不是(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)，后(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)就是(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)。此時除了(le)承(cheng)載功能(neng)外，還(huan)起(qi)到(dao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)、減速、差速的(de)(de)(de)(de)作用(yong)。在(zai)四輪(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)情(qing)況(kuang)下(xia)，通(tong)常在(zai)后(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)前面有(you)一個(ge)分動(dong)(dong)(dong)(dong)(dong)(dong)(dong)箱。后(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)分為整體橋(qiao)和(he)半(ban)軸(zhou)(zhou)(zhou)(zhou)。橋(qiao)梁采(cai)用(yong)非獨立(li)懸(xuan)掛，如(ru)(ru)鋼板彈(dan)簧懸(xuan)掛；半(ban)軸(zhou)(zhou)(zhou)(zhou)采(cai)用(yong)獨立(li)懸(xuan)架(jia)，如(ru)(ru)麥弗遜懸(xuan)架(jia)。前軸(zhou)(zhou)(zhou)(zhou)和(he)后(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)之間有(you)著本質的(de)(de)(de)(de)區別，不僅僅是(shi)(shi)在(zai)外觀上。后(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)指的(de)(de)(de)(de)是(shi)(shi)汽車后(hou)部(bu)的(de)(de)(de)(de)車軸(zhou)(zhou)(zhou)(zhou)。如(ru)(ru)果車輛由前軸(zhou)(zhou)(zhou)(zhou)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，那么后(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)只是(shi)(shi)一個(ge)從(cong)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)(zhou)，只起(qi)軸(zhou)(zhou)(zhou)(zhou)承(cheng)的(de)(de)(de)(de)作用(yong)。相反，如(ru)(ru)果前橋(qiao)不是(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)，那么后(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)就是(shi)(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)橋(qiao)。前軸(zhou)(zhou)(zhou)(zhou)除了(le)承(cheng)載功能(neng)外，還(huan)起(qi)到(dao)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)、減速和(he)差速器的(de)(de)(de)(de)作用(yong)。在(zai)四輪(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)情(qing)況(kuang)下(xia)，通(tong)常在(zai)后(hou)輪(lun)軸(zhou)(zhou)(zhou)(zhou)前面有(you)一個(ge)分動(dong)(dong)(dong)(dong)(dong)(dong)(dong)箱。
