Multi-disk friction device having improved lubrication characteristics

A multi-disk friction device comprising:

• a drive member having a plurality of drive disks supported for rotation with said drive member and a driven member having a plurality of driven disks supported for rotation with said driven member, said drive and driven disks interleaved relative to each other such that each drive disk is adjacent a driven disk and moveable toward and away from one another for providing selective frictional engagement therebetween and to transmit torque between said drive and driven members;
• each of said drive and driven disks including a working face which is disposed for frictional engagement with the working face of an adjacent one of said disks, at least one of said working faces on said adjacent one of said disks including a plurality of micro-pockets formed thereon with a depth of thirty percent of the thickness of said working face and arranged in a predetermined pattern relative to one another, said micro-pockets acting to store lubricating agents on said working face.
