一、手動變速箱油和自動變速箱油的區別有哪些
變(bian)(bian)速箱(xiang)(xiang)(xiang)分為手動(dong)變(bian)(bian)速箱(xiang)(xiang)(xiang)和(he)(he)自動(dong)變(bian)(bian)速箱(xiang)(xiang)(xiang)兩大類,它們使用的變(bian)(bian)速箱(xiang)(xiang)(xiang)油也是不同的,手動(dong)變(bian)(bian)速箱(xiang)(xiang)(xiang)油和(he)(he)自動(dong)變(bian)(bian)速箱(xiang)(xiang)(xiang)油的區別主要(yao)有:
1、作用不同
手動(dong)變(bian)速箱(xiang)油(you)和自動(dong)變(bian)速箱(xiang)油(you)都具(ju)有對行星齒輪組起(qi)到潤(run)滑、散(san)熱、清潔的作用,但(dan)自動(dong)變(bian)速箱(xiang)油(you)還具(ju)有作為液壓傳動(dong)的媒(mei)介的作用,這一點是手動(dong)變(bian)速箱(xiang)油(you)所不具(ju)有的。
2、性質不同
由于作(zuo)用不(bu)同,手(shou)動(dong)(dong)變(bian)速箱(xiang)(xiang)(xiang)油(you)和自動(dong)(dong)變(bian)速箱(xiang)(xiang)(xiang)油(you)黏度有明顯差(cha)異,手(shou)動(dong)(dong)變(bian)速箱(xiang)(xiang)(xiang)油(you)較為黏稠,自動(dong)(dong)變(bian)速箱(xiang)(xiang)(xiang)油(you)的(de)主要(yao)作(zuo)用是(shi)起(qi)到液壓傳動(dong)(dong),因此流(liu)動(dong)(dong)性非常(chang)好,抗泡性能和空氣(qi)釋放(fang)性能也比手(shou)動(dong)(dong)變(bian)速箱(xiang)(xiang)(xiang)油(you)的(de)要(yao)求更嚴(yan)。
3、顏色差別
手(shou)動變(bian)(bian)(bian)速(su)箱油大(da)部(bu)分是(shi)淺黃(huang)色(se)(新油),使(shi)(shi)用(yong)之后顏色(se)逐(zhu)(zhu)漸變(bian)(bian)(bian)深(shen)變(bian)(bian)(bian)黑。自動變(bian)(bian)(bian)速(su)箱油大(da)部(bu)分是(shi)鮮紅色(se)(也有(you)少(shao)數(shu)是(shi)淺黃(huang)色(se)),使(shi)(shi)用(yong)后顏色(se)逐(zhu)(zhu)漸變(bian)(bian)(bian)深(shen),變(bian)(bian)(bian)成暗紅色(se)、紅褐色(se)。
4、換法不同
手動變(bian)速箱(xiang)油(you)(you)的(de)更(geng)換(huan)一般是采(cai)用的(de)重力換(huan)油(you)(you)的(de)方法;自動變(bian)速箱(xiang)油(you)(you)更(geng)換(huan)則大多用的(de)是循環(huan)機換(huan)油(you)(you)的(de)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)(dong)(dong)變(bian)(bian)(bian)速(su)箱(xiang)(xiang)和(he)自動(dong)(dong)(dong)變(bian)(bian)(bian)速(su)箱(xiang)(xiang)由(you)于結構的(de)不(bu)同(tong),工作方式也(ye)不(bu)同(tong),使(shi)用(yong)(yong)(yong)的(de)變(bian)(bian)(bian)速(su)箱(xiang)(xiang)油在性(xing)能(neng)(neng)方面也(ye)有(you)較大的(de)區別,手動(dong)(dong)(dong)變(bian)(bian)(bian)速(su)箱(xiang)(xiang)的(de)油俗稱齒輪油,該油看起(qi)來比較干黏度也(ye)比較大;而自動(dong)(dong)(dong)變(bian)(bian)(bian)速(su)箱(xiang)(xiang)為自動(dong)(dong)(dong)變(bian)(bian)(bian)速(su)箱(xiang)(xiang)專用(yong)(yong)(yong)的(de)潤滑油,對(dui)流動(dong)(dong)(dong)性(xing)、抗(kang)泡(pao)性(xing)能(neng)(neng)和(he)空氣釋放性(xing)能(neng)(neng)等方面要求更高,二者不(bu)能(neng)(neng)通用(yong)(yong)(yong)。如果(guo)貿然將手動(dong)(dong)(dong)變(bian)(bian)(bian)速(su)箱(xiang)(xiang)油加到自動(dong)(dong)(dong)變(bian)(bian)(bian)速(su)箱(xiang)(xiang)里,可能(neng)(neng)會(hui)導致變(bian)(bian)(bian)速(su)箱(xiang)(xiang)機械(xie)部分損壞。
其實,不光是手動變速箱油和自動變速箱油不能通(tong)用,即使同為自動(dong)變速箱油(you),很多(duo)時候也是不能通(tong)用的(de),要根(gen)據汽車保養手冊(ce)的(de)要求(qiu)選擇合適型號的(de)變速箱油(you),切不可隨意選用。
