一、手動變速箱油和自動變速箱油的區別有哪些
變(bian)(bian)(bian)速箱分為手(shou)動變(bian)(bian)(bian)速箱和(he)自(zi)動變(bian)(bian)(bian)速箱兩(liang)大類,它們使用的變(bian)(bian)(bian)速箱油(you)也是不同的,手(shou)動變(bian)(bian)(bian)速箱油(you)和(he)自(zi)動變(bian)(bian)(bian)速箱油(you)的區別主(zhu)要有:
1、作用不同
手動變速(su)(su)箱(xiang)油(you)和自動變速(su)(su)箱(xiang)油(you)都具(ju)有(you)對行星(xing)齒輪組(zu)起到潤滑、散(san)熱、清潔的作(zuo)用(yong),但(dan)自動變速(su)(su)箱(xiang)油(you)還具(ju)有(you)作(zuo)為液壓傳動的媒介(jie)的作(zuo)用(yong),這一點是手動變速(su)(su)箱(xiang)油(you)所不具(ju)有(you)的。
2、性質不同
由于作用不同,手(shou)(shou)動(dong)(dong)變速(su)(su)箱(xiang)(xiang)(xiang)油和自動(dong)(dong)變速(su)(su)箱(xiang)(xiang)(xiang)油黏度有明顯差異,手(shou)(shou)動(dong)(dong)變速(su)(su)箱(xiang)(xiang)(xiang)油較為黏稠,自動(dong)(dong)變速(su)(su)箱(xiang)(xiang)(xiang)油的主要作用是起(qi)到液壓傳動(dong)(dong),因(yin)此流動(dong)(dong)性(xing)非常好,抗(kang)泡性(xing)能和空氣釋放性(xing)能也比手(shou)(shou)動(dong)(dong)變速(su)(su)箱(xiang)(xiang)(xiang)油的要求更嚴。
3、顏色差別
手動(dong)(dong)變(bian)(bian)速箱油大部(bu)分(fen)是淺黃色(新油),使(shi)用(yong)之后顏(yan)色逐漸(jian)變(bian)(bian)深(shen)變(bian)(bian)黑。自動(dong)(dong)變(bian)(bian)速箱油大部(bu)分(fen)是鮮紅色(也有少數是淺黃色),使(shi)用(yong)后顏(yan)色逐漸(jian)變(bian)(bian)深(shen),變(bian)(bian)成(cheng)暗紅色、紅褐(he)色。
4、換法不同
手(shou)動變速(su)箱(xiang)油(you)(you)的更換(huan)(huan)一般是采用的重力換(huan)(huan)油(you)(you)的方法;自動變速(su)箱(xiang)油(you)(you)更換(huan)(huan)則大多用的是循環機換(huan)(huan)油(you)(you)的方法。
二、手動變速箱油和自動變速箱油通用嗎
不通用。
手動(dong)變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)和(he)自動(dong)變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)由(you)于結(jie)構的不(bu)同,工(gong)作方(fang)式也(ye)不(bu)同,使用的變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)油(you)在性(xing)能方(fang)面也(ye)有較大(da)的區別(bie),手動(dong)變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)的油(you)俗稱齒輪油(you),該油(you)看起來(lai)比較干黏度也(ye)比較大(da);而自動(dong)變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)為自動(dong)變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)專用的潤滑油(you),對流動(dong)性(xing)、抗泡性(xing)能和(he)空(kong)氣釋(shi)放性(xing)能等方(fang)面要求更高(gao),二者不(bu)能通(tong)用。如果貿(mao)然將(jiang)手動(dong)變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)油(you)加到自動(dong)變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)里,可(ke)能會導(dao)致(zhi)變(bian)(bian)(bian)速(su)(su)(su)箱(xiang)機(ji)械部分損壞。
其實,不光是手動變速箱油和自動變速箱油不(bu)(bu)能(neng)通(tong)(tong)用(yong)(yong),即使(shi)同為自動(dong)變速箱油,很(hen)多時候也是不(bu)(bu)能(neng)通(tong)(tong)用(yong)(yong)的,要根據汽(qi)車保養手冊的要求選擇合適型號的變速箱油,切不(bu)(bu)可隨意選用(yong)(yong)。
