Abstract
A reversible friction plate including a generally circular, disk-like member having generally parallel, opposed friction surfaces, an opening in the center of the member, at least three, equally angularly spaced tangs extending radially outwardly from the periphery of the member, reaction member receiving apertures in each tang displaced from the center thereof in the circumferential direction, the reaction member receiving apertures in each tang being equally angularly spaced, and a spring mounting formation on each tang displaced from the center thereof in the circumferential direction oppositely from the reaction member receiving apertures. Also disclosed is a friction pack utilizing a plurality of the friction plates and a planetary gear transmission employing such a friction pack which eliminates precision machining in the fabrication thereof.
