前門外飾板簡介

汽車(che)的車(che)門下部(bu)外飾板是通過(guo)卡扣與鈑(ban)(ban)金(jin)件卡接在一起,外飾板的邊(bian)緣位置與鈑(ban)(ban)金(jin)貼合,通過(guo)雙面膠粘接固定。

汽車前圍板作用：

1、汽(qi)車(che)(che)覆(fu)蓋件(jian)（簡稱覆(fu)蓋件(jian)）是指構(gou)成(cheng)汽(qi)車(che)(che)車(che)(che)身或(huo)駕(jia)駛室、覆(fu)蓋發動機和底盤(pan)的(de)異形(xing)體表面和內部的(de)汽(qi)車(che)(che)零件(jian)。汽(qi)車(che)(che)覆(fu)蓋件(jian)既(ji)是外觀裝飾性的(de)零件(jian)，又是封閉薄殼(ke)狀(zhuang)的(de)受力(li)零件(jian)；
2、覆蓋(gai)件(jian)(jian)表面上任何(he)微小(xiao)的(de)缺(que)陷都會在涂漆后引(yin)(yin)起光線的(de)漫反射(she)而(er)損壞(huai)外(wai)形的(de)美觀，因(yin)此覆蓋(gai)件(jian)(jian)表面不允許有(you)波紋、皺折、邊緣(yuan)拉痕和其他破壞(huai)表面美感的(de)缺(que)陷。歐、美、日等發(fa)達國家(jia)生產的(de)A級表面精度的(de)汽(qi)車覆蓋(gai)件(jian)(jian)有(you)引(yin)(yin)擎(qing)蓋(gai)板；
3、車(che)(che)頂蓋(gai)(gai)(gai)(gai)，左、右車(che)(che)側圍(wei)(wei)，前(qian)(qian)(qian)、后(hou)(hou)(hou)車(che)(che)門(men)，前(qian)(qian)(qian)、后(hou)(hou)(hou)、左、右翼子板(ban)(ban)(ban)(ban)，行禮(li)箱蓋(gai)(gai)(gai)(gai)板(ban)(ban)(ban)(ban)，發動(dong)機(ji)前(qian)(qian)(qian)支撐(cheng)板(ban)(ban)(ban)(ban)，發動(dong)機(ji)前(qian)(qian)(qian)裙板(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)圍(wei)(wei)上(shang)蓋(gai)(gai)(gai)(gai)板(ban)(ban)(ban)(ban)，后(hou)(hou)(hou)圍(wei)(wei)板(ban)(ban)(ban)(ban)，后(hou)(hou)(hou)圍(wei)(wei)上(shang)蓋(gai)(gai)(gai)(gai)板(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)裙板(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)框架，前(qian)(qian)(qian)翼子板(ban)(ban)(ban)(ban)，車(che)(che)輪(lun)擋(dang)(dang)泥板(ban)(ban)(ban)(ban)、后(hou)(hou)(hou)翼子板(ban)(ban)(ban)(ban)、后(hou)(hou)(hou)圍(wei)(wei)板(ban)(ban)(ban)(ban)、行李倉蓋(gai)(gai)(gai)(gai)，后(hou)(hou)(hou)圍(wei)(wei)上(shang)蓋(gai)(gai)(gai)(gai)板(ban)(ban)(ban)(ban)、頂蓋(gai)(gai)(gai)(gai)、前(qian)(qian)(qian)圍(wei)(wei)側板(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)圍(wei)(wei)板(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)圍(wei)(wei)上(shang)蓋(gai)(gai)(gai)(gai)板(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)擋(dang)(dang)泥板(ban)(ban)(ban)(ban)、發動(dong)機(ji)罩。覆蓋(gai)(gai)(gai)(gai)件的(de)(de)制造是汽車(che)(che)車(che)(che)身(shen)制造的(de)(de)關(guan)鍵環節。
前(qian)圍板(ban)(ban)(ban)是(shi)指發(fa)動機艙(cang)與(yu)車廂之(zhi)間的(de)隔板(ban)(ban)(ban)，它(ta)和(he)地板(ban)(ban)(ban)、前(qian)立(li)柱聯接(jie)，安裝(zhuang)在(zai)前(qian)圍上蓋(gai)板(ban)(ban)(ban)之(zhi)下。前(qian)圍板(ban)(ban)(ban)上有許多孔口，作為(wei)操縱(zong)用(yong)的(de)拉線(xian)、拉桿、管路和(he)電(dian)線(xian)束通(tong)過(guo)之(zhi)用(yong)，還要(yao)配合踏(ta)板(ban)(ban)(ban)、方向(xiang)機柱等機件安裝(zhuang)位置。為(wei)防止發(fa)動機艙(cang)里(li)的(de)廢氣(qi)、高(gao)溫、噪聲竄入車廂，前(qian)圍板(ban)(ban)(ban)上要(yao)有密封措(cuo)施和(he)隔熱裝(zhuang)置。在(zai)發(fa)生意外事(shi)故時，它(ta)應具有足(zu)夠(gou)的(de)強度和(he)剛度。對比車身其它(ta)部件而(er)言，前(qian)圍板(ban)(ban)(ban)裝(zhuang)配最重要(yao)的(de)工藝(yi)技術(shu)是(shi)密封和(he)隔熱，它(ta)的(de)優劣往(wang)往(wang)反(fan)映(ying)了車輛運(yun)行的(de)質量(liang)。
