ABSTRACT:
The present invention utilizes simple dimethylsilicone fluids of the proper viscosity/molecular weight distribution to modify the low temperature properties of cycloaliphatic hydrocarbon fluids. Addition of the dimethylsilicone fluid to cycloaliphatic fluids improves their low temperature performance without degrading the requisite elastohydrodynamic shear strength properties. Low viscosity dimethylsilicone lubricating fluids combined with cycloaliphatic hydrocarbon fluids are suitable for use in infinitely variable transmissions and other traction-drive transmission providing good low temperature flow properties and high elastohydrodynamic shear strength.
