前橋總成簡介

前橋總(zong)成(cheng)(cheng)安裝在車身的(de)后半部分 用于撐起車身 包括 前橋殼、半軸、制動器總(zong)成(cheng)(cheng)、差減速器總(zong)成(cheng)(cheng) 帶動輪胎的(de)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)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)主要是(shi)(shi)(shi)通過離合器變速箱將(jiang)發動(dong)(dong)(dong)(dong)(dong)機(ji)(ji)動(dong)(dong)(dong)(dong)(dong)力減速并增加扭矩，再通過前(qian)(qian)(qian)(qian)橋(qiao)(qiao)總成(cheng)傳遞(di)給動(dong)(dong)(dong)(dong)(dong)力的(de)(de)最終(zhong)輸出(chu)輪。同(tong)時，前(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)還(huan)起(qi)(qi)到(dao)轉(zhuan)向(xiang)的(de)(de)作(zuo)(zuo)(zuo)用(yong)。此外(wai)，前(qian)(qian)(qian)(qian)橋(qiao)(qiao)還(huan)起(qi)(qi)到(dao)承(cheng)載(zai)整車(che)重(zhong)量(liang)的(de)(de)作(zuo)(zuo)(zuo)用(yong)，即車(che)身和(he)(he)前(qian)(qian)(qian)(qian)懸架通過連桿機(ji)(ji)構(gou)與前(qian)(qian)(qian)(qian)橋(qiao)(qiao)總成(cheng)連接(jie)，起(qi)(qi)到(dao)承(cheng)載(zai)的(de)(de)作(zuo)(zuo)(zuo)用(yong)。如(ru)果(guo)(guo)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)(shi)(shi)驅(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)，后(hou)(hou)輪軸(zhou)(zhou)(zhou)就是(shi)(shi)(shi)驅(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)。此時除(chu)了(le)承(cheng)載(zai)功能外(wai)，還(huan)起(qi)(qi)到(dao)驅(qu)動(dong)(dong)(dong)(dong)(dong)、減速、差速的(de)(de)作(zuo)(zuo)(zuo)用(yong)。在(zai)四輪驅(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)情(qing)況(kuang)下(xia)(xia)，通常(chang)在(zai)后(hou)(hou)輪軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)面(mian)有(you)一個分(fen)動(dong)(dong)(dong)(dong)(dong)箱。后(hou)(hou)輪軸(zhou)(zhou)(zhou)分(fen)為(wei)整體橋(qiao)(qiao)和(he)(he)半軸(zhou)(zhou)(zhou)。橋(qiao)(qiao)梁采(cai)用(yong)非獨立懸掛，如(ru)鋼板彈簧懸掛；半軸(zhou)(zhou)(zhou)采(cai)用(yong)獨立懸架，如(ru)麥弗遜懸架。前(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)和(he)(he)后(hou)(hou)輪軸(zhou)(zhou)(zhou)之間有(you)著(zhu)本質(zhi)的(de)(de)區別，不僅僅是(shi)(shi)(shi)在(zai)外(wai)觀上。后(hou)(hou)輪軸(zhou)(zhou)(zhou)指的(de)(de)是(shi)(shi)(shi)汽(qi)車(che)后(hou)(hou)部的(de)(de)車(che)軸(zhou)(zhou)(zhou)。如(ru)果(guo)(guo)車(che)輛由前(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)驅(qu)動(dong)(dong)(dong)(dong)(dong)，那么后(hou)(hou)輪軸(zhou)(zhou)(zhou)只(zhi)是(shi)(shi)(shi)一個從動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)，只(zhi)起(qi)(qi)軸(zhou)(zhou)(zhou)承(cheng)的(de)(de)作(zuo)(zuo)(zuo)用(yong)。相(xiang)反，如(ru)果(guo)(guo)前(qian)(qian)(qian)(qian)橋(qiao)(qiao)不是(shi)(shi)(shi)驅(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)，那么后(hou)(hou)輪軸(zhou)(zhou)(zhou)就是(shi)(shi)(shi)驅(qu)動(dong)(dong)(dong)(dong)(dong)橋(qiao)(qiao)。前(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)除(chu)了(le)承(cheng)載(zai)功能外(wai)，還(huan)起(qi)(qi)到(dao)驅(qu)動(dong)(dong)(dong)(dong)(dong)、減速和(he)(he)差速器的(de)(de)作(zuo)(zuo)(zuo)用(yong)。在(zai)四輪驅(qu)動(dong)(dong)(dong)(dong)(dong)的(de)(de)情(qing)況(kuang)下(xia)(xia)，通常(chang)在(zai)后(hou)(hou)輪軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)面(mian)有(you)一個分(fen)動(dong)(dong)(dong)(dong)(dong)箱。
