前門外飾板簡介

汽車的車門下部外飾(shi)板(ban)是通過卡(ka)扣與鈑金件卡(ka)接在一起,外飾(shi)板(ban)的邊緣位(wei)置(zhi)與鈑金貼合,通過雙面(mian)膠粘(zhan)接固定。

汽車前圍板作用：

1、汽(qi)車(che)覆(fu)(fu)蓋(gai)件(jian)(jian)(jian)（簡稱(cheng)覆(fu)(fu)蓋(gai)件(jian)(jian)(jian)）是(shi)指(zhi)構成汽(qi)車(che)車(che)身或駕駛室、覆(fu)(fu)蓋(gai)發動機(ji)和底盤的異形體表面和內部的汽(qi)車(che)零件(jian)(jian)(jian)。汽(qi)車(che)覆(fu)(fu)蓋(gai)件(jian)(jian)(jian)既是(shi)外觀裝飾性的零件(jian)(jian)(jian)，又是(shi)封閉(bi)薄(bo)殼狀的受(shou)力零件(jian)(jian)(jian)；
2、覆(fu)蓋(gai)件表面上任何微小(xiao)的(de)缺陷(xian)都會在涂漆后引起光線(xian)的(de)漫反射而(er)損(sun)壞外形的(de)美觀，因此(ci)覆(fu)蓋(gai)件表面不(bu)允許有(you)波(bo)紋、皺折、邊緣拉痕和其他破壞表面美感的(de)缺陷(xian)。歐、美、日等(deng)發達國家(jia)生產的(de)A級表面精度的(de)汽車(che)覆(fu)蓋(gai)件有(you)引擎蓋(gai)板；
3、車頂蓋(gai)(gai)(gai)，左、右(you)車側(ce)圍(wei)(wei)(wei)，前(qian)(qian)(qian)、后(hou)(hou)車門，前(qian)(qian)(qian)、后(hou)(hou)、左、右(you)翼子(zi)板(ban)(ban)(ban)(ban)(ban)(ban)，行(xing)禮箱蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)，發(fa)動機前(qian)(qian)(qian)支撐板(ban)(ban)(ban)(ban)(ban)(ban)，發(fa)動機前(qian)(qian)(qian)裙板(ban)(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)圍(wei)(wei)(wei)上(shang)蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)，后(hou)(hou)圍(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)(ban)，后(hou)(hou)圍(wei)(wei)(wei)上(shang)蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)裙板(ban)(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)框架，前(qian)(qian)(qian)翼子(zi)板(ban)(ban)(ban)(ban)(ban)(ban)，車輪擋泥板(ban)(ban)(ban)(ban)(ban)(ban)、后(hou)(hou)翼子(zi)板(ban)(ban)(ban)(ban)(ban)(ban)、后(hou)(hou)圍(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)(ban)、行(xing)李倉(cang)蓋(gai)(gai)(gai)，后(hou)(hou)圍(wei)(wei)(wei)上(shang)蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)、頂蓋(gai)(gai)(gai)、前(qian)(qian)(qian)圍(wei)(wei)(wei)側(ce)板(ban)(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)圍(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)圍(wei)(wei)(wei)上(shang)蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)擋泥板(ban)(ban)(ban)(ban)(ban)(ban)、發(fa)動機罩。覆(fu)蓋(gai)(gai)(gai)件的(de)制(zhi)造(zao)(zao)是汽車車身(shen)制(zhi)造(zao)(zao)的(de)關鍵環(huan)節。
前(qian)圍(wei)板(ban)是指發(fa)動機(ji)艙(cang)與車廂之(zhi)(zhi)間的隔(ge)板(ban)，它(ta)和(he)地板(ban)、前(qian)立(li)柱聯接，安裝(zhuang)(zhuang)在(zai)前(qian)圍(wei)上(shang)蓋板(ban)之(zhi)(zhi)下。前(qian)圍(wei)板(ban)上(shang)有(you)許多孔口，作為操縱用(yong)的拉(la)線、拉(la)桿、管路和(he)電線束通(tong)過之(zhi)(zhi)用(yong)，還要配合踏板(ban)、方向機(ji)柱等機(ji)件安裝(zhuang)(zhuang)位置。為防止(zhi)發(fa)動機(ji)艙(cang)里的廢氣、高(gao)溫(wen)、噪(zao)聲(sheng)竄入車廂，前(qian)圍(wei)板(ban)上(shang)要有(you)密(mi)封(feng)措施和(he)隔(ge)熱(re)裝(zhuang)(zhuang)置。在(zai)發(fa)生意外事故時，它(ta)應具有(you)足夠的強(qiang)度和(he)剛(gang)度。對比(bi)車身(shen)其它(ta)部件而言，前(qian)圍(wei)板(ban)裝(zhuang)(zhuang)配最重要的工藝技術是密(mi)封(feng)和(he)隔(ge)熱(re)，它(ta)的優劣往(wang)往(wang)反映(ying)了車輛(liang)運行的質量。
