Patent ID: 7399249

Claim:
A multidisk clutch ( 13 , 213 ) comprising a rotary body ( 22 , 250 ) having splines with spline surfaces formed thereon so as to extend helically along said rotary body, a number of planar disks ( 19 , 100 ) having side surfaces and central openings with inwardly extending teeth formed thereon, said disks being disposed on said rotary body in rotationally positive locking engagement with said rotary body ( 22 , 250 ), each of said teeth having engagement face areas ( 30 a , 30 b ) extending normal to the planar side surfaces of the teeth, said teeth being twisted out of the plane of the disks so as to extend in a direction normal to the surfaces of the helically extending splines wherein the face areas of the twisted teeth are in planar contact with the spline surfaces of the rotary body for the transmission of a torque between the rotary body and the disks ( 19 , 100 ).
