前橋總成簡介

前橋總(zong)成(cheng)安裝在車(che)(che)身的后(hou)半(ban)部分 用于撐(cheng)起車(che)(che)身 包括 前橋殼、半(ban)軸、制動器(qi)總(zong)成(cheng)、差(cha)減速器(qi)總(zong)成(cheng) 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)(che)(che)前(qian)(qian)(qian)(qian)(qian)橋(qiao)主要是通(tong)(tong)過離合器(qi)變速(su)(su)(su)箱(xiang)(xiang)將發動(dong)(dong)(dong)機動(dong)(dong)(dong)力減(jian)速(su)(su)(su)并增加(jia)扭矩，再通(tong)(tong)過前(qian)(qian)(qian)(qian)(qian)橋(qiao)總成(cheng)傳遞給動(dong)(dong)(dong)力的(de)(de)最終(zhong)輸出(chu)輪(lun)。同時(shi)，前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)還起(qi)(qi)到轉向的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)(yong)。此外，前(qian)(qian)(qian)(qian)(qian)橋(qiao)還起(qi)(qi)到承(cheng)(cheng)(cheng)載整車(che)(che)(che)重(zhong)量(liang)的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)(yong)，即車(che)(che)(che)身和前(qian)(qian)(qian)(qian)(qian)懸(xuan)(xuan)架通(tong)(tong)過連(lian)(lian)桿(gan)機構與前(qian)(qian)(qian)(qian)(qian)橋(qiao)總成(cheng)連(lian)(lian)接，起(qi)(qi)到承(cheng)(cheng)(cheng)載的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)(yong)。如(ru)(ru)果(guo)(guo)前(qian)(qian)(qian)(qian)(qian)橋(qiao)不是驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)，后(hou)輪(lun)軸(zhou)(zhou)(zhou)就是驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)。此時(shi)除了承(cheng)(cheng)(cheng)載功能外，還起(qi)(qi)到驅(qu)(qu)(qu)動(dong)(dong)(dong)、減(jian)速(su)(su)(su)、差(cha)速(su)(su)(su)的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)(yong)。在(zai)(zai)四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)情況(kuang)下，通(tong)(tong)常在(zai)(zai)后(hou)輪(lun)軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面有(you)一個分動(dong)(dong)(dong)箱(xiang)(xiang)。后(hou)輪(lun)軸(zhou)(zhou)(zhou)分為整體(ti)橋(qiao)和半(ban)軸(zhou)(zhou)(zhou)。橋(qiao)梁采用(yong)(yong)(yong)非(fei)獨(du)立懸(xuan)(xuan)掛(gua)，如(ru)(ru)鋼板彈簧懸(xuan)(xuan)掛(gua)；半(ban)軸(zhou)(zhou)(zhou)采用(yong)(yong)(yong)獨(du)立懸(xuan)(xuan)架，如(ru)(ru)麥弗遜(xun)懸(xuan)(xuan)架。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)和后(hou)輪(lun)軸(zhou)(zhou)(zhou)之間有(you)著本質的(de)(de)區別，不僅(jin)僅(jin)是在(zai)(zai)外觀上。后(hou)輪(lun)軸(zhou)(zhou)(zhou)指(zhi)的(de)(de)是汽車(che)(che)(che)后(hou)部的(de)(de)車(che)(che)(che)軸(zhou)(zhou)(zhou)。如(ru)(ru)果(guo)(guo)車(che)(che)(che)輛由前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)驅(qu)(qu)(qu)動(dong)(dong)(dong)，那(nei)么后(hou)輪(lun)軸(zhou)(zhou)(zhou)只是一個從動(dong)(dong)(dong)軸(zhou)(zhou)(zhou)，只起(qi)(qi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)(yong)。相反，如(ru)(ru)果(guo)(guo)前(qian)(qian)(qian)(qian)(qian)橋(qiao)不是驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)，那(nei)么后(hou)輪(lun)軸(zhou)(zhou)(zhou)就是驅(qu)(qu)(qu)動(dong)(dong)(dong)橋(qiao)。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)除了承(cheng)(cheng)(cheng)載功能外，還起(qi)(qi)到驅(qu)(qu)(qu)動(dong)(dong)(dong)、減(jian)速(su)(su)(su)和差(cha)速(su)(su)(su)器(qi)的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)(yong)。在(zai)(zai)四輪(lun)驅(qu)(qu)(qu)動(dong)(dong)(dong)的(de)(de)情況(kuang)下，通(tong)(tong)常在(zai)(zai)后(hou)輪(lun)軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面有(you)一個分動(dong)(dong)(dong)箱(xiang)(xiang)。
