ABSTRACT:
A torque transfer device embodying the concepts of the present invention utilizes a plurality of first apply torque plates and a plurality of second reaction torque plates. Each torque plate has a generally flat annular disk portion, and passages penetrate the flat disk portion of the torque plates. The disk portions of the first and second torque plates are interleaved, and an annular friction disk is interposed between the successively adjacent interleaved disk portions. Circumferentially spaced and annularly disposed apertures penetrate each friction disk. The passages in the flat disk portion of the first and second torque plates are located in register with the apertures penetrating the friction disks. Each friction disk may have a planar reverse surface that is attached to the disk portion of one torque plate. Each friction disk also has an obverse engaging face operatively to engage the successively adjacent disk portions. An annular channel is provided in the obverse engaging face of each friction disk, and the apertures are located within the channel. A plurality of circumferentially spaced recesses extend radially of the obverse engaging surface to intersect the channel.
