Abstract (en)
[origin: WO2008040382A1] In order to provide for a grease composition reducing or preventing noise, vibration and harshness (NVH) in the driveline, a grease composition for use in constant velocity joints is suggested, comprising a) a base oil composition; b) at least one tri-nuclear molybdenum compound of the formula Mo<SUB>3</SUB>S<SUB>k</SUB>L<SUB>n</SUB>Q<SUB>2</SUB>, wherein L are independently selected ligands having organo groups with a sufficient number of carbon atoms to render the compound soluble or dis- persible in the oil, n is from 1 to 4, k varies from 4 though 7, Q is selected from the group of neutral electron donating compounds such as amines, al- cohols, phosphines, and ethers, and z ranges from 0 to 5 and includes non- stoichiometric values. c) at least one further molybdenum containing compound; and d) at least one simple and/or complex soap thickener.
