前橋總成簡介

前橋總成(cheng)安(an)裝在車身(shen)的后(hou)半部(bu)分(fen) 用(yong)于(yu)撐起車身(shen) 包(bao)括 前橋殼、半軸、制動器(qi)總成(cheng)、差減速器(qi)總成(cheng) 帶動輪胎的運(yun)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)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)主要是(shi)通(tong)過離合(he)器變速箱(xiang)(xiang)將發動(dong)(dong)(dong)(dong)機動(dong)(dong)(dong)(dong)力(li)減速并增加扭矩，再通(tong)過前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)總(zong)成(cheng)傳遞給(gei)動(dong)(dong)(dong)(dong)力(li)的(de)最終輸出輪(lun)(lun)。同(tong)時，前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)還起(qi)(qi)到轉向(xiang)的(de)作(zuo)用。此外(wai)(wai)，前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)還起(qi)(qi)到承載整(zheng)車(che)重量的(de)作(zuo)用，即車(che)身和(he)前(qian)(qian)(qian)(qian)(qian)懸(xuan)架通(tong)過連桿機構與(yu)前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)總(zong)成(cheng)連接(jie)，起(qi)(qi)到承載的(de)作(zuo)用。如(ru)果(guo)前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)不(bu)是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)(qiao)，后輪(lun)(lun)軸(zhou)(zhou)(zhou)就(jiu)是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)(qiao)。此時除(chu)了承載功能(neng)外(wai)(wai)，還起(qi)(qi)到驅(qu)(qu)動(dong)(dong)(dong)(dong)、減速、差速的(de)作(zuo)用。在四輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)的(de)情況(kuang)下(xia)，通(tong)常(chang)在后輪(lun)(lun)軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面有一個分(fen)(fen)(fen)動(dong)(dong)(dong)(dong)箱(xiang)(xiang)。后輪(lun)(lun)軸(zhou)(zhou)(zhou)分(fen)(fen)(fen)為整(zheng)體橋(qiao)(qiao)(qiao)(qiao)(qiao)和(he)半(ban)軸(zhou)(zhou)(zhou)。橋(qiao)(qiao)(qiao)(qiao)(qiao)梁(liang)采用非獨立懸(xuan)掛(gua)，如(ru)鋼(gang)板彈簧(huang)懸(xuan)掛(gua)；半(ban)軸(zhou)(zhou)(zhou)采用獨立懸(xuan)架，如(ru)麥弗遜(xun)懸(xuan)架。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)和(he)后輪(lun)(lun)軸(zhou)(zhou)(zhou)之間有著本質的(de)區(qu)別，不(bu)僅(jin)僅(jin)是(shi)在外(wai)(wai)觀上(shang)。后輪(lun)(lun)軸(zhou)(zhou)(zhou)指的(de)是(shi)汽(qi)車(che)后部的(de)車(che)軸(zhou)(zhou)(zhou)。如(ru)果(guo)車(che)輛(liang)由前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)驅(qu)(qu)動(dong)(dong)(dong)(dong)，那么后輪(lun)(lun)軸(zhou)(zhou)(zhou)只(zhi)是(shi)一個從(cong)動(dong)(dong)(dong)(dong)軸(zhou)(zhou)(zhou)，只(zhi)起(qi)(qi)軸(zhou)(zhou)(zhou)承的(de)作(zuo)用。相反(fan)，如(ru)果(guo)前(qian)(qian)(qian)(qian)(qian)橋(qiao)(qiao)(qiao)(qiao)(qiao)不(bu)是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)(qiao)，那么后輪(lun)(lun)軸(zhou)(zhou)(zhou)就(jiu)是(shi)驅(qu)(qu)動(dong)(dong)(dong)(dong)橋(qiao)(qiao)(qiao)(qiao)(qiao)。前(qian)(qian)(qian)(qian)(qian)軸(zhou)(zhou)(zhou)除(chu)了承載功能(neng)外(wai)(wai)，還起(qi)(qi)到驅(qu)(qu)動(dong)(dong)(dong)(dong)、減速和(he)差速器的(de)作(zuo)用。在四輪(lun)(lun)驅(qu)(qu)動(dong)(dong)(dong)(dong)的(de)情況(kuang)下(xia)，通(tong)常(chang)在后輪(lun)(lun)軸(zhou)(zhou)(zhou)前(qian)(qian)(qian)(qian)(qian)面有一個分(fen)(fen)(fen)動(dong)(dong)(dong)(dong)箱(xiang)(xiang)。

寶馬3系(進口)簡介

作為(wei)寶馬的(de)當家花(hua)旦，3系以卓越的(de)性能，特有的(de)駕駛樂趣，得到了真正的(de)世界車(che)的(de)美譽，被認為(wei)是全球緊湊級(ji)豪華轎車(che)執牛耳者，而其(qi)真實表現也不(bu)愧于這個稱(cheng)號。干練(lian)舒展的(de)車(che)身(shen)造型，已經可以被歸(gui)入(ru)經典(dian)設計的(de)行列，車(che)內空間也許在(zai)眾多國(guo)人的(de)認識中會(hui)覺得很小，但我們認為(wei)，其(qi)空間也絕對夠用，不(bu)能成為(wei)拒絕購買的(de)理由，前置發動機(ji)加(jia)后輪(lun)驅動，是其(qi)真正的(de)精髓所在(zai)。
