A friction clutch including interleaved compressible friction plates or overlapping conical rings and selectively operable structure effecting engagement thereof. One aspect of the invention relates to the structure for utilizing torque generated between the parts to be clutched for providing the compression force to be applied to the plates or the cone rings. Roller and ramp structure is provided between driving and driven parts responding to torque initially applied to the driving member for generating an axial force which is then applied to the clutch pack compressing structure. The roller has an elongated structure which will permit it to first roll about an axis perpendicular to the axis of rotation of the friction clutch and subsequently slide along its axial length. This structure will prevent or at least considerably reduce the power surges following a complete clutching operation.
In a shiftable friction clutch for gear drives including a shaft, a carrier having inclined first surfaces thereon, a collar which surrounds and is supported axially movably with respect to said shaft, and first and second clutch halves having cooperable friction surfaces, said first clutch half having at least one friction ring which is axially movable with respect to said shaft and has second surfaces which are arranged on an axially facing surface thereof facing away from said clutch friction surfaces and are inclined with respect to the plane of rotation of said friction ring, said first and second surfaces opposing one another, the improvement comprising at least one sliding member provided between said second inclined surfaces on said friction ring and said first inclined surfaces on said carrier.
