液(ye)(ye)(ye)(ye)(ye)壓傳(chuan)動(dong)(dong)(dong)(dong)是利用液(ye)(ye)(ye)(ye)(ye)體壓力能傳(chuan)遞動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong)，又稱(cheng)(cheng)為容積式(shi)液(ye)(ye)(ye)(ye)(ye)壓傳(chuan)動(dong)(dong)(dong)(dong)。液(ye)(ye)(ye)(ye)(ye)力傳(chuan)動(dong)(dong)(dong)(dong)是借助于液(ye)(ye)(ye)(ye)(ye)體動(dong)(dong)(dong)(dong)能傳(chuan)遞動(dong)(dong)(dong)(dong)力的傳(chuan)動(dong)(dong)(dong)(dong)，實際是一種(zhong)以液(ye)(ye)(ye)(ye)(ye)體為工作(zuo)介質(zhi)的能量轉(zhuan)換裝置(zhi)，有耦合器(qi)、變矩(ju)器(qi)兩種(zhong)形式(shi)。用作(zuo)液(ye)(ye)(ye)(ye)(ye)壓系統傳(chuan)動(dong)(dong)(dong)(dong)介質(zhi)的油稱(cheng)(cheng)為液(ye)(ye)(ye)(ye)(ye)壓油，我們稱(cheng)(cheng)之為液(ye)(ye)(ye)(ye)(ye)力傳(chuan)動(dong)(dong)(dong)(dong)油，又稱(cheng)(cheng)液(ye)(ye)(ye)(ye)(ye)壓液(ye)(ye)(ye)(ye)(ye)。用作(zuo)液(ye)(ye)(ye)(ye)(ye)力傳(chuan)動(dong)(dong)(dong)(dong)介質(zhi)的油。我們稱(cheng)(cheng)之為液(ye)(ye)(ye)(ye)(ye)力傳(chuan)動(dong)(dong)(dong)(dong)油，又稱(cheng)(cheng)自動(dong)(dong)(dong)(dong)排檔油、方向機(ji)油、助力器(qi)油等，昆侖抗磨液(ye)(ye)(ye)(ye)(ye)壓油價格，國外稱(cheng)(cheng)之為自動(dong)(dong)(dong)(dong)變速器(qi)油。

液(ye)力傳動用油(you)(you)(you)國外叫做自動變(bian)速器(qi)(qi)油(you)(you)(you)(ATF)，國內(nei)稱液(ye)力傳動油(you)(you)(you)。自動變(bian)速器(qi)(qi)是一(yi)種以(yi)液(ye)體為(wei)介(jie)質轉(zhuan)換能量的(de)裝置，內(nei)裝有變(bian)矩(ju)器(qi)(qi)、齒(chi)輪(lun)機(ji)構、液(ye)壓機(ji)構、濕(shi)式離(li)合(he)器(qi)(qi)等(deng)。由于這(zhe)些機(ji)構都是使用一(yi)種油(you)(you)(you)，所以(yi)要(yao)求所用油(you)(you)(you)品(pin)應該(gai)具有齒(chi)輪(lun)油(you)(you)(you)的(de)抗燒結(jie)性(xing)(xing)(xing)能，液(ye)壓油(you)(you)(you)的(de)低溫流動性(xing)(xing)(xing)，內(nei)燃機(ji)油(you)(you)(you)的(de)清(qing)凈(jing)分(fen)散(san)性(xing)(xing)(xing)，以(yi)及(ji)優良的(de)防止氧化安定性(xing)(xing)(xing)、抗泡性(xing)(xing)(xing)、防銹(xiu)性(xing)(xing)(xing)，耐橡校的(de)密封性(xing)(xing)(xing)等(deng)，山東抗磨液(ye)壓油(you)(you)(you)，因(yin)此，該(gai)油(you)(you)(you)在(zai)潤滑油(you)(you)(you)中是要(yao)求綜(zong)合(he)性(xing)(xing)(xing)能的(de)一(yi)種，選(xuan)用其它任何油(you)(you)(you)品(pin)代用都是不(bu)適宜的(de)。
