    摘要: Grease composition for constant velocity joints comprising a base oil and urea-based thickener, which grease further comprises, (A) from 0.1 to 10% by weight of an optionally substituted molybdenum-organocyclic compound containing at least 5 ring atoms, wherein each ring atom attached directly to the molybdenum atom is a hetero atom, (B) from 0.1 to 5% by weight of at least one sulphur-containing additive chosen from the group consisting of sulphur olefins, sulphur-phosphorus extreme-pressure agents, ashless dithiocarbamates, polysulphides, thiadiazoles and zinc dithiocarbamate, and (C) from 0.1 to 5% by weight of at least one phosphorous-containing additive chosen from the group consisting of molybdenum dithiophosphate, zinc dithiophosphate and triphenylphosphorothionate; a method of lubricating a constant velocity joint comprising packing it with said grease and a constant velocity joint packed with said grease.
