Lubricating oil composition for continuously variable transmission |
摘要 |
To provide a lubricating oil composition for continuously variable transmission which ensures both a high coefficient of friction between metals required for a push belt-type CTV oil and an excellent wear preventing property relative to a belt and a pulley. A lubricating oil composition for continuously variable transmission is provided, which comprises a lubricating base oil made of a mineral oil and/or a synthetic oil formulated with a metal detergent and a phosphorus-based wear preventive characterized in that a ratio between a content (ppm) of a metal derived from said metal detergent and based on the total weight of the lubricating oil composition and a total base number (mg KOH/g) ranges 0.75-4.5 (ppm/mg KOH/g), and a ratio between the content (ppm) of the metal derived from said metal detergent and a content of phosphorus derived from said phosphorus-based wear preventive ranges 0.5-2.0 (ppm/ppm).
