Description
Case No. 3218 TITLE
Transmission Lubricating Compositions with Improved Performance, Contain-ing Acid/Polyamine Condensation Product FIELD OF INVENTION
[0001] The present invention relates to an oil of lubricating viscosity con-taining the condensation product of a polyamine and an acid, a hydrocarbyl phosphite and boron containing compounds. The composition has improved wear properties. The composition can be used in automatic transmission fluids.
BACKGROUND OF THE INVENTION
Transmission Lubricating Compositions with Improved Performance, Contain-ing Acid/Polyamine Condensation Product FIELD OF INVENTION
[0001] The present invention relates to an oil of lubricating viscosity con-taining the condensation product of a polyamine and an acid, a hydrocarbyl phosphite and boron containing compounds. The composition has improved wear properties. The composition can be used in automatic transmission fluids.
BACKGROUND OF THE INVENTION
[0002] It is known to add various additives to an oil of lubricating viscosity for automatic transmission fluids (hereinafter referred to as ATF) to improve resistance to wear, decrease anti-shudder properties and provide the appropriate friction properties. Friction properties of an ATF have to be balanced to provide high dynamic torque for efficient clutch engagement capacity and high static friction for good clutch holding. The ATF also has to provide a positive friction versus speed curve slope for good anti-shudder durability. These competing requirements are difficult to balance. In addition antiwear properties need to be sufficient for gear durability.
[0003] In an effort to overcome these issues vehicle manufacturers have defined specifications; for example, The Ford Motor Company have the MER-CONOV specification. These specifications highlight a number of tests that ATF's and other lubricating oil compositions should satisfy. For ATF's to satisfy wear requirements, to decrease anti-shudder properties and to have the appropriate friction properties, important tests include "The Ford/Greening Low Speed Friction Test", "The Timken Wear Test" and "The Ford Clutch Friction Durability Test." Many known lubricating oil compositions for ATF systems successfully pass one or two of the named tests above. From an automotive manufacturers perspective it would be desirable to have one composition capa-ble of passing all three of the above named tests.
[0004] US Patent 6,482,777 discloses a lubricating composition for a trans-mission package containing at least one saturated fatty phosphate ester or salt and optionally either at least one fatty acid imidazoline or the reaction product of a fatty acid and polyalkylene polyamine and/or a borated dispersant, wherein the lubricating composition is free of saturated fatty phosphites. The composi-tion exhibits improved friction properties and optionally improved thermal stability.
[0005] US 5,759,965 discloses the combination of boron containing over-based materials, borated epoxides, borated dispersants, a variety of phosphorus acid esters and derivatives thereof and an oil of lubricating viscosity.
[0006] US 6,528,458 disclose the combination of 2,5-dimercapto-1,3,4-thiadiazole, imidazoline, borated epoxides and short chain phosphites and, in a different example, borated dispersants.
[0007] US Patent 6,103,673 discloses a composition containing at least 0.1 wt% of an overbased metal salt and contributing 0.5 to 10 total base number (TBN) to the composition, at least 0.1 wt% of a phosphorus compound, 0.1 to 0.25 wt% of a combination of friction modifiers selected from zinc salts of fatty acids with at least 10 carbon atoms, hydrocarbyl imidazolines containing at least 12 carbon atoms in the hydrocarbyl group and borated epoxides.

[0009] It would be desirable to have compositions with improved wear resistance. The invention further provides anti-shudder properties and the appropriate friction properties. The invention further provides compositions suitable for use in a variety of automatic transmission fluids.
