前橋總成簡介

前橋(qiao)總(zong)成(cheng)安裝在車(che)身的(de)后半(ban)部分(fen) 用于撐起車(che)身 包括 前橋(qiao)殼(ke)、半(ban)軸、制動器(qi)總(zong)成(cheng)、差減(jian)速器(qi)總(zong)成(cheng) 帶(dai)動輪胎的(de)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)(qian)橋(qiao)(qiao)(qiao)主(zhu)要是(shi)通(tong)過離合器變速箱將發(fa)動(dong)(dong)(dong)(dong)機動(dong)(dong)(dong)(dong)力(li)減(jian)速并增(zeng)加(jia)扭矩，再通(tong)過前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)總(zong)成傳遞給動(dong)(dong)(dong)(dong)力(li)的(de)(de)最終輸出輪(lun)(lun)。同時(shi)(shi)，前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)還起(qi)(qi)(qi)到轉向的(de)(de)作(zuo)(zuo)(zuo)用(yong)。此外(wai)，前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)還起(qi)(qi)(qi)到承載(zai)整車(che)重量的(de)(de)作(zuo)(zuo)(zuo)用(yong)，即車(che)身和前(qian)(qian)(qian)(qian)(qian)懸(xuan)(xuan)架通(tong)過連桿機構與前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)總(zong)成連接，起(qi)(qi)(qi)到承載(zai)的(de)(de)作(zuo)(zuo)(zuo)用(yong)。如果(guo)前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)不(bu)是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)，后(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)就(jiu)是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)。此時(shi)(shi)除了(le)(le)承載(zai)功能外(wai)，還起(qi)(qi)(qi)到驅(qu)(qu)動(dong)(dong)(dong)(dong)、減(jian)速、差(cha)速的(de)(de)作(zuo)(zuo)(zuo)用(yong)。在四(si)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)的(de)(de)情況下，通(tong)常在后(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面(mian)有(you)一(yi)個分動(dong)(dong)(dong)(dong)箱。后(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)分為整體橋(qiao)(qiao)(qiao)和半(ban)軸(zhou)(zhou)(zhou)。橋(qiao)(qiao)(qiao)梁采用(yong)非獨(du)立(li)懸(xuan)(xuan)掛，如鋼(gang)板彈簧懸(xuan)(xuan)掛；半(ban)軸(zhou)(zhou)(zhou)采用(yong)獨(du)立(li)懸(xuan)(xuan)架，如麥弗遜懸(xuan)(xuan)架。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)和后(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)之間有(you)著(zhu)本(ben)質的(de)(de)區(qu)別，不(bu)僅(jin)(jin)僅(jin)(jin)是(shi)在外(wai)觀(guan)上。后(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)指的(de)(de)是(shi)汽(qi)車(che)后(hou)部(bu)的(de)(de)車(che)軸(zhou)(zhou)(zhou)。如果(guo)車(che)輛由前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)驅(qu)(qu)動(dong)(dong)(dong)(dong)，那(nei)么后(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)只(zhi)是(shi)一(yi)個從動(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)，只(zhi)起(qi)(qi)(qi)軸(zhou)(zhou)(zhou)承的(de)(de)作(zuo)(zuo)(zuo)用(yong)。相反，如果(guo)前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)不(bu)是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)，那(nei)么后(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)就(jiu)是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)除了(le)(le)承載(zai)功能外(wai)，還起(qi)(qi)(qi)到驅(qu)(qu)動(dong)(dong)(dong)(dong)、減(jian)速和差(cha)速器的(de)(de)作(zuo)(zuo)(zuo)用(yong)。在四(si)輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)的(de)(de)情況下，通(tong)常在后(hou)輪(lun)(lun)軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面(mian)有(you)一(yi)個分動(dong)(dong)(dong)(dong)箱。

力帆邁威簡介
