具有改进的摩擦性能和燃料经济性的自动变速器油组合物及包含其的自动变速器的离合器
摘要：
本发明提供具有改进的摩擦性能和燃料经济性的自动变速器油组合物及包含其的自动变速器的离合器。具体地，本发明提供一种具有改进的摩擦性能和燃料经济性的自动变速器油组合物，所述自动变速器油组合物包含：约68重量％至80重量％的基础油；约5重量％至15重量％的聚亚烷基二醇油；以及约3重量％至10重量％的由以下化学式1表示的琥珀酸酐衍生物，其中R为C2‑C30的烯基。该组合物通过提高离合器的摩擦性能并改进自动变速器的效率来改进燃料经济性和耐磨性。
摘要（英）：

The invention provides an automatic transmission oil composition improving frictional property and fuel economy and a clutch for the automatic transmission comprising the same. Particularly, the invention provides an automatic transmission oil composition improving frictional property and fuel economy. The automatic transmission oil composition includes: : about 68% to 80% by weight of base oil; about 5% to 15% by weight of polyalkylene glycol oil; and about 3% to 10% by weight of the following a succinic anhydride derivative represented by a chemical formula 1, wherein R is an alkenyl group of C2-C30. The composition improves fuel economy and abrasion resistance by enhancing a frictional property of a clutch and improving efficiency of the automatic transmission.
