前橋總成簡介

前(qian)橋總(zong)(zong)成(cheng)安(an)裝在(zai)車身(shen)(shen)的(de)后半(ban)(ban)部分 用于撐起車身(shen)(shen) 包括(kuo) 前(qian)橋殼(ke)、半(ban)(ban)軸(zhou)、制動器總(zong)(zong)成(cheng)、差減速器總(zong)(zong)成(cheng) 帶動輪胎(tai)的(de)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。
