汽(qi)車(che)的(de)(de)雨(yu)刷器(qi)(qi)是通(tong)過(guo)雨(yu)刷器(qi)(qi)電(dian)機(ji)驅動(dong)(dong)(dong)(dong)。用電(dian)位器(qi)(qi)來控制幾(ji)個檔(dang)位的(de)(de)電(dian)機(ji)轉(zhuan)速(su)。雨(yu)刷器(qi)(qi)電(dian)機(ji)后(hou)端(duan)的(de)(de)有封閉在同一個殼體(ti)內的(de)(de)小型(xing)齒輪變速(su)器(qi)(qi),使(shi)輸出的(de)(de)轉(zhuan)速(su)降低至需要的(de)(de)轉(zhuan)速(su)。這個裝置(zhi)(zhi)俗稱叫雨(yu)刷驅動(dong)(dong)(dong)(dong)總(zong)(zong)成(cheng)。該總(zong)(zong)成(cheng)的(de)(de)輸出軸(zhou)連接雨(yu)刷端(duan)部機(ji)械裝置(zhi)(zhi),通(tong)過(guo)撥叉驅動(dong)(dong)(dong)(dong)和彈簧復位提升雨(yu)刷的(de)(de)往復擺(bai)(bai)動(dong)(dong)(dong)(dong)。比如說，汽(qi)車(che)雨(yu)刮器(qi)(qi)電(dian)路原理，雨(yu)刮器(qi)(qi)總(zong)(zong)成(cheng)含(han)有電(dian)動(dong)(dong)(dong)(dong)機(ji)、減(jian)(jian)速(su)器(qi)(qi)、四連桿機(ji)構、刮水臂心軸(zhou)、刮水片(pian)總(zong)(zong)成(cheng)等。當司機(ji)按下雨(yu)刮器(qi)(qi)的(de)(de)開關時,電(dian)動(dong)(dong)(dong)(dong)機(ji)啟動(dong)(dong)(dong)(dong),電(dian)動(dong)(dong)(dong)(dong)機(ji)的(de)(de)轉(zhuan)速(su)經過(guo)蝸輪蝸桿的(de)(de)減(jian)(jian)速(su)增扭作用驅動(dong)(dong)(dong)(dong)擺(bai)(bai)臂,擺(bai)(bai)臂帶動(dong)(dong)(dong)(dong)四連桿機(ji)構,四連桿機(ji)構帶動(dong)(dong)(dong)(dong)安裝在前圍板上的(de)(de)轉(zhuan)軸(zhou)左(zuo)右擺(bai)(bai)動(dong)(dong)(dong)(dong),后(hou)由轉(zhuan)軸(zhou)帶動(dong)(dong)(dong)(dong)雨(yu)刮片(pian)刮掃擋風玻璃。

? 現在汽車(che)的(de)(de)雨刮(gua)(gua)(gua)臂(bei)有(you)(you)(you)兩個(ge),電(dian)機(ji)一般是一個(ge),稱為“單機(ji)雙臂(bei)”,也有(you)(you)(you)每(mei)個(ge)雨刮(gua)(gua)(gua)器(qi)帶一只電(dian)機(ji),稱為“單機(ji)單臂(bei)”。有(you)(you)(you)些雨刮(gua)(gua)(gua)臂(bei)還附帶膠(jiao)水(shui)管,水(shui)管接至(zhi)洗(xi)滌器(qi)上,按一下開關會有(you)(you)(you)水(shui)注噴向前(qian)檔(dang)(dang)風玻(bo)璃。在一些中轎(jiao)車(che)上,不(bu)(bu)但前(qian)后檔(dang)(dang)風玻(bo)璃有(you)(you)(you)雨刮(gua)(gua)(gua)器(qi),就(jiu)是前(qian)大燈也有(you)(you)(you)一支小小的(de)(de)雨刮(gua)(gua)(gua)片,用以清(qing)除前(qian)燈玻(bo)璃上的(de)(de)塵埃。汽車(che)雨刮(gua)(gua)(gua)電(dian)機(ji)需要多少錢，主要看(kan)用什么(me)檔(dang)(dang)次的(de)(de)車(che)來確(que)定(ding)了，國產的(de)(de)幾十元，德國的(de)(de)幾千(qian)元都有(you)(you)(you)的(de)(de)。車(che)型不(bu)(bu)同決(jue)定(ding)了汽車(che)雨刮(gua)(gua)(gua)電(dian)機(ji)也不(bu)(bu)同，使用的(de)(de)不(bu)(bu)同價(jia)格上也不(bu)(bu)相(xiang)同。
