A fat composition for use in homokinetic joints comprising at least one trinuclear molybdenum compound and a urea derivative thickener

摘要

Grease composition having good compatibility with cuffs made of rubber or thermoplastic elastomer, and which moreover provides low wear and low friction when used in a CVJ and is primarily intended for use in homokinetic joints a) a base oil composition; b) at least one trinuclear molybdenum compound corresponding to the formula Mo SUB 3 / SUB S SUB k / SUB L SUB n / SUB Q SUB z / SUB, in the L's are independently selected ligands having organo groups with a sufficient number of carbon atoms to render the compound soluble or dispersible in the oil, where n ranges from 1 to 4, k ranges from 4 to 7, Q from the group of neutral Electron donor compounds such as amines, alcohols, phosphines and ethers, and z ranges from 0 to 5 and includes non-stoichiometric values; c) at least one urea derivative thickener.
