Document Type and Number:
WIPO Patent Application WO/2019/167812
Kind Code:
A1
Abstract:
The present invention relates to a lubricating oil composition and a continuously-variable transmission filled with the lubricating oil composition. The present invention also relates to a friction control method for a continuously-variable transmission, the method using the lubricating oil composition. This lubricating oil composition is characterized by containing: (A) a base oil; (B) a diamine; (C) a glycolic acid amide; and (D) a phosphorous ester. With this lubricating oil composition, it is possible to provide different wear characteristics between different parts, so in a preferable embodiment of the present invention, the lubricating oil composition is suitably used as a lubricating oil for variable transmissions, in particular, metal-belt continuously-variable transmissions.
