ABSTRACT:
A grease composition for constant velocity joints comprises (a) a base oil; (b) a lithium-containing thickener selected from the group consisting of lithium soap and lithium complex soap; (c) an organic molybdenum compound selected from the group consisting of molybdenum dithiophosphates and molybdenum dithiocarbamates; (d) a zinc dithiophosphate; (e) a sulfur-phosphorus extreme pressure agent free of any metal; and (f) a calcium salt selected from the group consisting of calcium salts of oxidized waxes, calcium salts of petroleum sulfonates and calcium salts of alkyl aromatic sulfonates. The grease composition for constant velocity joints exhibits a substantially improved effect of reducing friction coefficient and a substantially improved effect of reducing the axial force proportional to the third order component of rotation.
