    • 1428557 Resilient couplings FRANCAISE DU FERODO SA 4 May 1973 [5 May 1972 (2)] 21318/73 Heading F2U The friction damper of a resilient coupling (e.g. in an automotive clutch plate) comprises axially between relatively rotatable (at least over a sector) parts 11, 14 with interposed circumferentially acting resilient means (e.g. springs 20) two friction washers, 27A, 27B, 28A, 28B, each (e.g. 27A, 28A) co-rotative with one of the parts (e.g. 11) from which it is separated by another of the washers (e.g. 27B, 28B) co-rotative with the other part (e.g. 14). The clutch plate may comprise either a hub flange 11 between two plates 14, 15 rigidly connected, or one plate between two hub flanges. The springs 20 may be all similar or not, and some may be mounted with lost motion. The plates 14, 15 may be connected by a rivet (17), Fig. 2 (not shown), received loosely in a recess in either the flange perimeter or in the inner edge of the flange window 12 for the spring, to limit the relative rotation. The friction washers 27A, 27B, 28A, 28B may be connected to the respective parts either by axial tongues 30B, 32A on the washers or the parts engaging recesses 31B, 33A, or by recesses in radial lugs on the washers engaging the rivets (17). The washers may be connected with lost motion, and may have a low friction (e.g. PTFE) washer adjacent one of the parts. The washers may be axially loaded by a corrugated spring 25.
