前門外飾板簡介

汽(qi)車(che)的車(che)門下(xia)部外飾(shi)板是通(tong)過卡(ka)扣與(yu)鈑金(jin)件卡(ka)接(jie)在一起,外飾(shi)板的邊緣位置與(yu)鈑金(jin)貼合(he),通(tong)過雙面膠(jiao)粘接(jie)固定。

汽車前圍板作用：

1、汽(qi)車(che)覆蓋件（簡(jian)稱覆蓋件）是指構成汽(qi)車(che)車(che)身或駕駛室、覆蓋發動機和底盤的(de)(de)異形體表面和內部的(de)(de)汽(qi)車(che)零(ling)(ling)件。汽(qi)車(che)覆蓋件既是外觀裝(zhuang)飾性的(de)(de)零(ling)(ling)件，又是封閉薄(bo)殼狀(zhuang)的(de)(de)受力零(ling)(ling)件；
2、覆(fu)蓋(gai)件表(biao)面(mian)(mian)上任何微小的(de)缺陷(xian)(xian)都會在(zai)涂漆(qi)后引起光(guang)線的(de)漫(man)反射(she)而損壞外形的(de)美(mei)(mei)觀，因此覆(fu)蓋(gai)件表(biao)面(mian)(mian)不允許有(you)(you)波紋、皺折、邊緣拉(la)痕和(he)其(qi)他破壞表(biao)面(mian)(mian)美(mei)(mei)感的(de)缺陷(xian)(xian)。歐、美(mei)(mei)、日等發達(da)國家生產(chan)的(de)A級表(biao)面(mian)(mian)精度的(de)汽車(che)覆(fu)蓋(gai)件有(you)(you)引擎蓋(gai)板；
3、車(che)頂(ding)蓋(gai)(gai)，左、右(you)車(che)側(ce)圍(wei)(wei)，前(qian)(qian)(qian)、后(hou)車(che)門，前(qian)(qian)(qian)、后(hou)、左、右(you)翼子板(ban)(ban)(ban)(ban)(ban)，行禮箱蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，發動機前(qian)(qian)(qian)支撐板(ban)(ban)(ban)(ban)(ban)，發動機前(qian)(qian)(qian)裙板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)圍(wei)(wei)上(shang)(shang)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，后(hou)圍(wei)(wei)板(ban)(ban)(ban)(ban)(ban)，后(hou)圍(wei)(wei)上(shang)(shang)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)裙板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)框架(jia)，前(qian)(qian)(qian)翼子板(ban)(ban)(ban)(ban)(ban)，車(che)輪擋泥板(ban)(ban)(ban)(ban)(ban)、后(hou)翼子板(ban)(ban)(ban)(ban)(ban)、后(hou)圍(wei)(wei)板(ban)(ban)(ban)(ban)(ban)、行李倉蓋(gai)(gai)，后(hou)圍(wei)(wei)上(shang)(shang)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)、頂(ding)蓋(gai)(gai)、前(qian)(qian)(qian)圍(wei)(wei)側(ce)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)圍(wei)(wei)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)圍(wei)(wei)上(shang)(shang)蓋(gai)(gai)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)擋泥板(ban)(ban)(ban)(ban)(ban)、發動機罩。覆蓋(gai)(gai)件(jian)的(de)制(zhi)造(zao)是汽車(che)車(che)身制(zhi)造(zao)的(de)關(guan)鍵環(huan)節。
前(qian)圍(wei)(wei)板(ban)是指(zhi)發(fa)動(dong)機艙(cang)與車(che)廂(xiang)之(zhi)間的隔(ge)板(ban)，它和(he)(he)地板(ban)、前(qian)立柱(zhu)聯接，安(an)裝(zhuang)在(zai)前(qian)圍(wei)(wei)上蓋板(ban)之(zhi)下(xia)。前(qian)圍(wei)(wei)板(ban)上有(you)(you)許多孔(kong)口，作為(wei)操縱用的拉(la)線(xian)、拉(la)桿、管路(lu)和(he)(he)電線(xian)束通過(guo)之(zhi)用，還(huan)要(yao)配合踏板(ban)、方向機柱(zhu)等機件安(an)裝(zhuang)位置。為(wei)防止(zhi)發(fa)動(dong)機艙(cang)里的廢氣、高溫、噪聲(sheng)竄入車(che)廂(xiang)，前(qian)圍(wei)(wei)板(ban)上要(yao)有(you)(you)密(mi)封措(cuo)施和(he)(he)隔(ge)熱裝(zhuang)置。在(zai)發(fa)生(sheng)意外事故時，它應具有(you)(you)足夠的強度(du)和(he)(he)剛度(du)。對比(bi)車(che)身(shen)其它部件而言，前(qian)圍(wei)(wei)板(ban)裝(zhuang)配最重要(yao)的工藝(yi)技術是密(mi)封和(he)(he)隔(ge)熱，它的優劣往往反映了(le)車(che)輛運行的質(zhi)量。
