Abstract:
The present invention relates to an antiwear agent and lubricating compositions thereof. The invention further provides for a method of lubricating a driveline device application by employing a lubricating composition containing the antiwear agent.

Claim (Index 1):
A method for lubricating a driveline device comprising supplying to the driveline device a lubricating composition comprising an oil of lubricating viscosity and an antiwear package wherein the antiwear package comprises\n (a) 0.01 wt % to 3 wt % of a derivative of a hydroxycarboxylic acid, wherein the derivative of a hydroxycarboxylic acid is represented by the formula: wherein\n n and m both equal 2; \n X is an aliphatic or alicyclic group, or an aliphatic or alicyclic group containing an oxygen atom in the carbon chain, or a substituted group of the foregoing types, said group containing up to 6 carbon atoms and having n+m available points of attachment; \n two Ys together representing the nitrogen of an imide structure R\u2014N<formed between two carbonyl groups; \n R is a hydrocarbyl group; \n each R 2  is independently hydrogen, a hydrocarbyl group or an acyl group, further provided that at least one \u2014OR 2  group is located on a carbon atom within X that is \u03b1 or \u03b2 to at least one of the \u2014C(O)\u2014Y\u2014R groups, and \n (b) 0.05 wt % to 2 wt % of a phosphorus compound, wherein the phosphorus compound is an amine salt of a phosphate hydrocarbon ester represented by the formula: \n wherein R 3  and R 4  are independently hydrogen or hydrocarbon containing 4 to 40 carbon atoms, with the proviso that at least one is a hydrocarbon group; and\n R 5 , R 6 , R 7  and R 8  independently hydrogen or a hydrocarbyl group, with the proviso that at least one is a hydrocarbyl group.
