COMPOSITION OF Grease FOR USE IN CONSTANT SPEED JOINTS. To provide a grease composition for reducing or preventing noise, vibration and roughness (NVH) in the driving unit, a grease composition for use in constant speed joints is suggested, which comprises a) a base oil composition; b) at least one trinuclear molybdenum compound of the formula Mo ~ 3 ~ S ~ k ~ L ~ n ~ Q ~ 2 ~, where L are independently selected ligands that have the organo groups with a sufficient number of carbon atoms to take the oil-soluble or dispersible compound, n is from 1 to 4, k ranges from 4 to 7, Q is selected from the group of neutral electron donating compounds such as amines, alcohols, phosphines and ethers and z is in the range 0 to 5 and includes non-stoichiometric values. c) at least one other compound containing molybdenum and d) at least one simple and / or thickening complex soap. |
