Disclosed is a magneto-rheological fluid composition which comprises magnetic particles, a fluid, a dispersant, a structure stabilizer and an anti-friction additive. Particularly, the magnetic particles include non-coated magnetic particles and polyvinyl butyral-coated magnetic particles at the weight ratio of about 1:1 to 4:1. Accordingly, dispersion stability and yield stress are improved substantially when magnetic field is applied to the magneto-rheological fluid.

Magneto-rheological fluid composition

This invention relates to a grease for constant velocity joints which comprises of organic molybdenum compound, antimondialkyl dithiocarbamate (referred as Sb-DTC), zinc dithiophosphate and organic sulfide with conventionally used lithium grease or lithium aluminum grease and particularly as an organic molybdenum compound is used molybdenum dialkyldithio carbamate having good thermal stability, low friction coefficient and good extreme pressure.
