Fluid for traction drive

Details

Inventors: Tsubouchi, Toshiyuki; Hata, Hitoshi;
Assignee: Idemitsu Kosan Company Limited (Tokyo, JP)
Primary Examiner:

Attorney, Agent or Firm:

A fluid for traction drive is described, containing a liquid material as a base stock wherein the liquid material is prepared by bringing naphthalene or tetralin into contact with a Friedel-Crafts catalyst and then hydrogenating the resulting compounds. This traction drive fluid exhibits a superior traction coefficient from low temperature to elevated temperature and further has a low viscosity. Thus the fluid contributes to the production of small-sized drive mechanisms and can be widely used in various machines.

DETAILED DESCRIPTION An object of the invention is to provide a fluid for traction drive which is free from the problems as described above and meets various requirements.
The present invention relates to a fluid for traction drive which contains as a base stock a liquid material prepared by bringing naphthalene or tetralin into contact with a Friedel-Crafts catalyst and, thereafter, hydrogenating resultant compounds.
