前門外飾板簡介

汽車的車門(men)下(xia)部外飾板是(shi)通過(guo)卡(ka)扣與(yu)(yu)鈑金(jin)件(jian)卡(ka)接(jie)在一起,外飾板的邊緣位置與(yu)(yu)鈑金(jin)貼(tie)合(he),通過(guo)雙面膠粘接(jie)固定。

汽車前圍板作用：

1、汽車覆(fu)蓋件(jian)(jian)（簡稱(cheng)覆(fu)蓋件(jian)(jian)）是(shi)指(zhi)構成汽車車身或駕駛室、覆(fu)蓋發動機和底盤的(de)異形體(ti)表面和內(nei)部的(de)汽車零(ling)(ling)件(jian)(jian)。汽車覆(fu)蓋件(jian)(jian)既(ji)是(shi)外觀裝飾性的(de)零(ling)(ling)件(jian)(jian)，又是(shi)封閉(bi)薄殼狀(zhuang)的(de)受力零(ling)(ling)件(jian)(jian)；
2、覆蓋件(jian)表面上(shang)任何微小(xiao)的(de)(de)(de)缺陷都會在涂漆后(hou)引起光線(xian)的(de)(de)(de)漫反射而損壞(huai)外形(xing)的(de)(de)(de)美(mei)(mei)(mei)觀，因(yin)此(ci)覆蓋件(jian)表面不允許有波紋、皺折、邊緣拉痕和其(qi)他破壞(huai)表面美(mei)(mei)(mei)感(gan)的(de)(de)(de)缺陷。歐、美(mei)(mei)(mei)、日等發達國(guo)家生產(chan)的(de)(de)(de)A級表面精度的(de)(de)(de)汽(qi)車(che)覆蓋件(jian)有引擎蓋板；
3、車(che)頂(ding)蓋(gai)(gai)(gai)，左、右(you)車(che)側(ce)圍(wei)(wei)(wei)，前(qian)(qian)(qian)、后(hou)車(che)門，前(qian)(qian)(qian)、后(hou)、左、右(you)翼(yi)(yi)子板(ban)(ban)(ban)(ban)(ban)，行禮箱蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，發動機(ji)前(qian)(qian)(qian)支(zhi)撐板(ban)(ban)(ban)(ban)(ban)，發動機(ji)前(qian)(qian)(qian)裙板(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)，后(hou)圍(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)，后(hou)圍(wei)(wei)(wei)上(shang)蓋(gai)(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，前(qian)(qian)(qian)翼(yi)(yi)子板(ban)(ban)(ban)(ban)(ban)，車(che)輪擋(dang)泥板(ban)(ban)(ban)(ban)(ban)、后(hou)翼(yi)(yi)子板(ban)(ban)(ban)(ban)(ban)、后(hou)圍(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)、行李倉蓋(gai)(gai)(gai)，后(hou)圍(wei)(wei)(wei)上(shang)蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)、頂(ding)蓋(gai)(gai)(gai)、前(qian)(qian)(qian)圍(wei)(wei)(wei)側(ce)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)圍(wei)(wei)(wei)板(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)、前(qian)(qian)(qian)擋(dang)泥板(ban)(ban)(ban)(ban)(ban)、發動機(ji)罩(zhao)。覆蓋(gai)(gai)(gai)件的制造(zao)是汽車(che)車(che)身制造(zao)的關(guan)鍵(jian)環節。
前(qian)圍(wei)板(ban)(ban)(ban)是指(zhi)發動機(ji)艙與車(che)廂之間的(de)(de)隔(ge)(ge)板(ban)(ban)(ban)，它(ta)和(he)地板(ban)(ban)(ban)、前(qian)立(li)柱聯接，安裝在前(qian)圍(wei)上蓋板(ban)(ban)(ban)之下。前(qian)圍(wei)板(ban)(ban)(ban)上有(you)許多孔口，作為操縱用的(de)(de)拉線、拉桿、管路和(he)電線束通過之用，還要配(pei)(pei)合踏板(ban)(ban)(ban)、方向機(ji)柱等(deng)機(ji)件安裝位置(zhi)。為防止發動機(ji)艙里(li)的(de)(de)廢氣(qi)、高溫、噪聲竄入車(che)廂，前(qian)圍(wei)板(ban)(ban)(ban)上要有(you)密(mi)封措施和(he)隔(ge)(ge)熱(re)裝置(zhi)。在發生意(yi)外事故時，它(ta)應(ying)具有(you)足夠的(de)(de)強度(du)(du)和(he)剛度(du)(du)。對比車(che)身其它(ta)部(bu)件而言，前(qian)圍(wei)板(ban)(ban)(ban)裝配(pei)(pei)最(zui)重(zhong)要的(de)(de)工藝(yi)技術是密(mi)封和(he)隔(ge)(ge)熱(re)，它(ta)的(de)(de)優(you)劣(lie)往(wang)往(wang)反映了車(che)輛運行(xing)的(de)(de)質量。
