前橋總成簡介

前橋總成(cheng)安裝在車(che)身(shen)的后(hou)半部分 用(yong)于撐起車(che)身(shen) 包括 前橋殼、半軸、制動(dong)器(qi)總成(cheng)、差減(jian)速(su)器(qi)總成(cheng) 帶動(dong)輪胎的運轉(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(qi)車(che)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)主要(yao)是(shi)(shi)(shi)通過離合器變速(su)(su)箱將(jiang)發動(dong)(dong)(dong)機動(dong)(dong)(dong)力減(jian)速(su)(su)并增加扭矩，再(zai)通過前(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)總成傳遞給(gei)動(dong)(dong)(dong)力的(de)(de)(de)(de)最終輸出輪(lun)(lun)。同(tong)時(shi)，前(qian)(qian)(qian)(qian)軸(zhou)(zhou)還起到(dao)(dao)(dao)轉向的(de)(de)(de)(de)作用(yong)。此(ci)外，前(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)還起到(dao)(dao)(dao)承載(zai)(zai)(zai)整車(che)重量的(de)(de)(de)(de)作用(yong)，即(ji)車(che)身和前(qian)(qian)(qian)(qian)懸(xuan)(xuan)(xuan)架通過連(lian)桿機構與前(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)總成連(lian)接，起到(dao)(dao)(dao)承載(zai)(zai)(zai)的(de)(de)(de)(de)作用(yong)。如(ru)(ru)(ru)果前(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)不(bu)是(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)，后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)就是(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)。此(ci)時(shi)除了(le)承載(zai)(zai)(zai)功(gong)(gong)能外，還起到(dao)(dao)(dao)驅(qu)(qu)(qu)動(dong)(dong)(dong)、減(jian)速(su)(su)、差速(su)(su)的(de)(de)(de)(de)作用(yong)。在(zai)四輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)(de)(de)情(qing)況下，通常(chang)在(zai)后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)前(qian)(qian)(qian)(qian)面有(you)(you)一(yi)個分動(dong)(dong)(dong)箱。后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)分為整體(ti)橋(qiao)(qiao)(qiao)和半軸(zhou)(zhou)。橋(qiao)(qiao)(qiao)梁(liang)采用(yong)非(fei)獨(du)立懸(xuan)(xuan)(xuan)掛，如(ru)(ru)(ru)鋼(gang)板彈簧懸(xuan)(xuan)(xuan)掛；半軸(zhou)(zhou)采用(yong)獨(du)立懸(xuan)(xuan)(xuan)架，如(ru)(ru)(ru)麥弗遜懸(xuan)(xuan)(xuan)架。前(qian)(qian)(qian)(qian)軸(zhou)(zhou)和后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)之間有(you)(you)著(zhu)本質的(de)(de)(de)(de)區別，不(bu)僅(jin)僅(jin)是(shi)(shi)(shi)在(zai)外觀上(shang)。后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)指的(de)(de)(de)(de)是(shi)(shi)(shi)汽(qi)車(che)后(hou)(hou)(hou)部的(de)(de)(de)(de)車(che)軸(zhou)(zhou)。如(ru)(ru)(ru)果車(che)輛由前(qian)(qian)(qian)(qian)軸(zhou)(zhou)驅(qu)(qu)(qu)動(dong)(dong)(dong)，那么(me)后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)只(zhi)是(shi)(shi)(shi)一(yi)個從動(dong)(dong)(dong)軸(zhou)(zhou)，只(zhi)起軸(zhou)(zhou)承的(de)(de)(de)(de)作用(yong)。相反(fan)，如(ru)(ru)(ru)果前(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)不(bu)是(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)，那么(me)后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)就是(shi)(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)(qiao)(qiao)。前(qian)(qian)(qian)(qian)軸(zhou)(zhou)除了(le)承載(zai)(zai)(zai)功(gong)(gong)能外，還起到(dao)(dao)(dao)驅(qu)(qu)(qu)動(dong)(dong)(dong)、減(jian)速(su)(su)和差速(su)(su)器的(de)(de)(de)(de)作用(yong)。在(zai)四輪(lun)(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)(de)(de)情(qing)況下，通常(chang)在(zai)后(hou)(hou)(hou)輪(lun)(lun)軸(zhou)(zhou)前(qian)(qian)(qian)(qian)面有(you)(you)一(yi)個分動(dong)(dong)(dong)箱。
