Title:
LUBRICANT COMPOSITION FOR NON-STAGE TRANSMISSION
Document Type and Number:
Japanese Patent JP2021006617
Kind Code:
A
Abstract:
To provide a lubricant composition that satisfies seizure resistance, wear resistance, and fatigue resistance required for a push belt type non-stage transmission oil, and can improve fuel efficiency of a wet clutch and a metal belt while maintaining a high transmission torque capacity of the wet clutch and the metal belt.SOLUTION: The lubricant composition for a push belt type non-stage transmission comprises: (A) a lubricant base oil containing one or more wax isomerized base oils and having a specific kinematic viscosity and viscosity index; (B) poly (meth) acrylate with a specific weight average molecular weight; (C) a boron-containing succinate imide compound; (D) a boric acid ester compound; and (E) an over basic calcium-based cleaning agent, wherein kinematic viscosity at 40°C is 25 mm2/s or less, the viscosity index is 180 or more, and a ratio of boron content to calcium content is 0.5 to 1.5.SELECTED DRAWING: None
