WORKING FLUID FOR TRACTION DRIVE

摘要

The working fluid for traction drive use has a particularly high traction coefficient at high temperatures and the principal ingredient thereof is a decahydronaphthalene compound substituted, on either one or both of the decahydronaphthalene rings, with two or three substituent groups which may be cyclohexyl groups, cyclohexyl alkyl groups, e.g. cyclohexyl methyl, cyclohexyl ethyl, 1-methyl-1-cyclohexyl ethyl and 1methyl-1-(methylcyclohexyl) ethyl groups, or a combination thereof. The working fluid can be a mixture of a base oil of various types and the above mentioned decahydronaphthalene compound in an amount of 5 to 250 parts by weight per 100 parts by weight of the base oil.
