汽車的(de)(de)雨(yu)(yu)(yu)刷(shua)器(qi)(qi)(qi)是通(tong)過(guo)雨(yu)(yu)(yu)刷(shua)器(qi)(qi)(qi)電(dian)(dian)(dian)機(ji)(ji)傳(chuan)動(dong)(dong)(dong)(dong)。用(yong)電(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)來(lai)控(kong)制幾個(ge)檔位(wei)的(de)(de)電(dian)(dian)(dian)機(ji)(ji)轉(zhuan)(zhuan)速。雨(yu)(yu)(yu)刷(shua)器(qi)(qi)(qi)電(dian)(dian)(dian)機(ji)(ji)后端的(de)(de)有封閉在(zai)同一(yi)個(ge)殼體內的(de)(de)小(xiao)型齒輪變速器(qi)(qi)(qi),使(shi)輸(shu)出的(de)(de)轉(zhuan)(zhuan)速降低至(zhi)需要的(de)(de)轉(zhuan)(zhuan)速。這個(ge)裝(zhuang)置俗稱叫雨(yu)(yu)(yu)刷(shua)傳(chuan)動(dong)(dong)(dong)(dong)總(zong)(zong)成。該(gai)總(zong)(zong)成的(de)(de)輸(shu)出軸連接雨(yu)(yu)(yu)刷(shua)端部(bu)機(ji)(ji)械裝(zhuang)置,通(tong)過(guo)撥(bo)叉傳(chuan)動(dong)(dong)(dong)(dong)和彈(dan)簧(huang)復位(wei)實現雨(yu)(yu)(yu)刷(shua)的(de)(de)往復擺(bai)動(dong)(dong)(dong)(dong)。比如說，汽車雨(yu)(yu)(yu)刮(gua)器(qi)(qi)(qi)電(dian)(dian)(dian)路(lu)原理，雨(yu)(yu)(yu)刮(gua)器(qi)(qi)(qi)總(zong)(zong)成含有電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)、減速器(qi)(qi)(qi)、四(si)(si)連桿(gan)機(ji)(ji)構、刮(gua)水(shui)臂心軸、刮(gua)水(shui)片總(zong)(zong)成等。當(dang)司(si)機(ji)(ji)按下雨(yu)(yu)(yu)刮(gua)器(qi)(qi)(qi)的(de)(de)開關時,電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)啟動(dong)(dong)(dong)(dong),電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)的(de)(de)轉(zhuan)(zhuan)速經過(guo)蝸輪蝸桿(gan)的(de)(de)減速增扭(niu)作用(yong)傳(chuan)動(dong)(dong)(dong)(dong)擺(bai)臂,擺(bai)臂帶(dai)動(dong)(dong)(dong)(dong)四(si)(si)連桿(gan)機(ji)(ji)構,四(si)(si)連桿(gan)機(ji)(ji)構帶(dai)動(dong)(dong)(dong)(dong)安裝(zhuang)在(zai)前圍板(ban)上的(de)(de)轉(zhuan)(zhuan)軸左右擺(bai)動(dong)(dong)(dong)(dong),后由轉(zhuan)(zhuan)軸帶(dai)動(dong)(dong)(dong)(dong)雨(yu)(yu)(yu)刮(gua)片刮(gua)掃擋風(feng)玻璃。

? 現在汽車的雨刮臂有兩個,電機一般是一個,稱為“單機雙臂”,也有每個雨刮器帶一只電機,稱為“單機單臂”。有些雨刮臂還附帶膠水管,水管接至洗滌器上,按一下開關會有水注噴向前檔風玻璃。在一些中轎車上,不但前后檔風玻璃有雨刮器,就是前大燈也有一支小小的雨刮片,用以清除前燈玻璃上的塵埃。汽車雨刮電機需要多少錢，主要看用什么檔次的車來確定了，國產的幾十元，德國的幾千元都有的。車型不同決定了汽車雨刮電機也不同(tong)，使用的不同(tong)價格上也不相同(tong)。
