前門外飾板簡介

汽車(che)的車(che)門下部外(wai)飾板是通過卡(ka)扣與鈑金件卡(ka)接在(zai)一起,外(wai)飾板的邊(bian)緣位置(zhi)與鈑金貼(tie)合,通過雙面膠粘接固(gu)定。

汽車前圍板作用：

1、汽車(che)(che)覆(fu)蓋(gai)(gai)件(jian)(jian)（簡(jian)稱(cheng)覆(fu)蓋(gai)(gai)件(jian)(jian)）是指構成汽車(che)(che)車(che)(che)身或駕(jia)駛室、覆(fu)蓋(gai)(gai)發動機和底盤的異形體表面和內部的汽車(che)(che)零(ling)件(jian)(jian)。汽車(che)(che)覆(fu)蓋(gai)(gai)件(jian)(jian)既是外觀(guan)裝飾性(xing)的零(ling)件(jian)(jian)，又是封閉薄殼(ke)狀的受力(li)零(ling)件(jian)(jian)；
2、覆(fu)蓋件(jian)(jian)表面上任何微小的(de)(de)(de)缺(que)陷(xian)都會在涂(tu)漆后引起光線的(de)(de)(de)漫(man)反射而損壞(huai)(huai)外形的(de)(de)(de)美(mei)觀，因此(ci)覆(fu)蓋件(jian)(jian)表面不允許有(you)波紋、皺折、邊緣拉痕和其他(ta)破壞(huai)(huai)表面美(mei)感的(de)(de)(de)缺(que)陷(xian)。歐、美(mei)、日等發達(da)國家生產的(de)(de)(de)A級(ji)表面精(jing)度的(de)(de)(de)汽車覆(fu)蓋件(jian)(jian)有(you)引擎蓋板(ban)；
3、車頂蓋(gai)(gai)(gai)，左、右車側(ce)圍，前(qian)(qian)(qian)(qian)、后(hou)(hou)車門，前(qian)(qian)(qian)(qian)、后(hou)(hou)、左、右翼子板(ban)(ban)(ban)(ban)(ban)，行(xing)禮箱蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，發(fa)(fa)動(dong)機前(qian)(qian)(qian)(qian)支撐板(ban)(ban)(ban)(ban)(ban)，發(fa)(fa)動(dong)機前(qian)(qian)(qian)(qian)裙板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)(qian)圍上蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，后(hou)(hou)圍板(ban)(ban)(ban)(ban)(ban)，后(hou)(hou)圍上蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)(qian)裙板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)(qian)框(kuang)架(jia)，前(qian)(qian)(qian)(qian)翼子板(ban)(ban)(ban)(ban)(ban)，車輪(lun)擋(dang)泥(ni)板(ban)(ban)(ban)(ban)(ban)、后(hou)(hou)翼子板(ban)(ban)(ban)(ban)(ban)、后(hou)(hou)圍板(ban)(ban)(ban)(ban)(ban)、行(xing)李倉蓋(gai)(gai)(gai)，后(hou)(hou)圍上蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)、頂蓋(gai)(gai)(gai)、前(qian)(qian)(qian)(qian)圍側(ce)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)(qian)圍板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)(qian)圍上蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)(qian)擋(dang)泥(ni)板(ban)(ban)(ban)(ban)(ban)、發(fa)(fa)動(dong)機罩。覆蓋(gai)(gai)(gai)件的(de)制造(zao)是(shi)汽車車身制造(zao)的(de)關鍵環節(jie)。
前圍板(ban)(ban)(ban)(ban)是指發(fa)動機艙(cang)與車廂(xiang)之間(jian)的隔板(ban)(ban)(ban)(ban)，它和地(di)板(ban)(ban)(ban)(ban)、前立柱聯接，安裝(zhuang)(zhuang)在前圍上(shang)蓋板(ban)(ban)(ban)(ban)之下。前圍板(ban)(ban)(ban)(ban)上(shang)有許多孔口，作(zuo)為操縱用(yong)(yong)的拉線、拉桿(gan)、管(guan)路和電線束通過之用(yong)(yong)，還要配(pei)合踏板(ban)(ban)(ban)(ban)、方(fang)向機柱等機件安裝(zhuang)(zhuang)位(wei)置。為防止發(fa)動機艙(cang)里的廢氣(qi)、高溫(wen)、噪(zao)聲竄入車廂(xiang)，前圍板(ban)(ban)(ban)(ban)上(shang)要有密(mi)封(feng)(feng)措施和隔熱(re)裝(zhuang)(zhuang)置。在發(fa)生意外事故時，它應具(ju)有足(zu)夠的強度(du)和剛度(du)。對比(bi)車身其它部件而(er)言，前圍板(ban)(ban)(ban)(ban)裝(zhuang)(zhuang)配(pei)最重要的工(gong)藝技術(shu)是密(mi)封(feng)(feng)和隔熱(re)，它的優劣往往反映(ying)了車輛運行的質量(liang)。
