LUBRICATING OIL COMPOSITION FOR CONTINUOUSLY VARIABLE TRANSMISSION

摘要

There is provided a lubricating oil composition for continuously variable transmission which is capable of enhancing a power transmission capacity of CVTs of various type including a metallic belt type, a chain type and a traction drive type, and keeping the enhanced power transmission capacity. The lubricating oil composition for continuously variable transmission according to the present invention includes (A) a base oil comprising a hydrocarbon compound having a cohesive energy density at 40°C of 0.180 GPa or more, and having a kinematic viscosity at 40°C of 5 to 150 mm 2 /s, and (B) a phosphoric ester containing a alkyl group having a thioether bond, and/or (C) at least one compound selected from the group consisting of phosphoric esters and amine salts thereof, and an overbased calcium sulfonate.
