Abstract (en)

A traction drive fluid composition comprising the following component (A), <CHEM> wherein R1 to R10 are hydrogen, C1-C3 alkyl, or cyclohexyl, Q1 to Q4 are C1-C3 alkyl or cyclohexyl, and n1 to n4 are an integer from 0 to 5; component (B) which is a heat copolymer of a cyclopentadiene compound and a vinyl aromatic hydrocarbon compound or a hydrogenated product of thereof having a softening point of 40 DEG C or higher or a weight average molecular weight of 250 or larger; and, optionally, component (C) which is a compound with a viscosity smaller than that of component (A); a phosphorous compound; and a friction modifier. The composition exhibits a high traction coefficient over a wide temperature range and excellent friction characteristics required for a traction drive device.
