    摘要: An object of the present invention is to provide a lubricating oil composition capable of improving oxidation stability by allowing a base number to remain, preserving seizure resistance, preventing generation of precipitation to be caused due to addition of a base, and inhibiting a lowering of traction coefficient. The lubricating oil composition for traction drive transmission includes (A) a base oil, (B) a phosphate ester-based compound, (C) an antioxidant, and (D) an amine represented by the following general formula (I) and/or an amine oxide of the amine. In the general formula (I), each of R1 and R2 independently represents a linear, branched, or cyclic alkyl group having 1 to 26 carbon atoms, a linear, branched, or cyclic alkenyl group having 1 to 26 carbon atoms, (R4—O)m—H, or (R5—O)n1—(R6—O)n2—H, and R1 and R2 may be the same as or different from each other; each of R4 to R6 independently represents an alkylene group having 2 to 3 carbon atoms; each of m, n1, and n2 independently represents a number of 2 to 25; and R3 represents a substituted or unsubstituted, linear, branched, or cyclic alkyl group having 1 to 26 carbon atoms, or a substituted or unsubstituted, linear, branched, or cyclic alkenyl group having 1 to 26 carbon atoms.

    摘要: A dispersant includes the reaction product of an amine and at least one equivalent of glycidyl ether where the amine is selected from a group consisting of aminoethylpiperazine, bis(2-(piperazin-1-yl)ethyl)amine, 4,4′-methylenebiscyclohexylamine, m-xylenediamine, diethylenetriamine, and triethylenetetramine and where the glycidyl ether has the structure (A), where R is selected from aromatic carbon chains, non-aromatic carbon chains and polyalkylene glycol groups. The dispersant is useful in a lubricant with a base oil for increasing soot dispersibility of the lubricant.
