摘　　要：目前在市场上主要有液力机械自动变速器(AT)、无级自动变速器(CVT)、电控机械式自动变速器(AMT)以及双离合器式自动变速器(DCT)。它们都有各自的特点,分别占据一定的市场份额。不同结构的自动变速器所用润滑油均为专用油,那么专用油主要区别在哪?文章以CVT变速箱油(CVTF)标准中LFW-1钢对钢摩擦特性试验为例,来阐述不同油品摩擦性能的差异,以及不同类型自动变速箱油品不能通用和互换的原因。Currently,there are mainly hydraulic mechanical automatic transmissions(AT),continuously variable transmissions(CVT),electronically controlled mechanical automated manual transmission(AMT)and dual-clutch transmissions(DCT)on the market,which occupy a certain market share for their own characteristics respectively.The lubricants used in automatic transmissions with different structures are all special oils.So what are the main differences between them?Taking the LFW-1 steel-to-steel friction characteristics test in the CVT fluid(CVTF)standards as an example,the paper expounds the differences in friction properties of different oils and the reasons why different types of automatic transmission oils are not universal and interchangeable.
