    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.

    (54) DEVICE FOR GASH FRICTION CLUTCH CLUTCH 1 The invention relates to a transport engineering, namely to devices for damping oscillations of a vehicle friction clutch. A device for damping torsional vibrations of a friction clutch of a vehicle coupling comprising at least one notch disk mounted with the possibility of angular displacement on the hub of a clutch driven disk made with a flange having openings, springs located in the openings of the flange and the notches of the said disk, and at least the friction washers located between the disk and the hub flange l. A disadvantage of the known devices is the insufficient efficiency of damping torsion rings. Fucking due to insufficient size of the working surface friction. The aim of the invention is to increase its efficiency by increasing the working surfaces of the friction. This goal is achieved by the fact that in the proposed device one of the mentioned friction washers of the swirling oscillations of the vehicle with the flange of the hub and the other with the disk. On the periphery of the friction washers, protrusions can be made, and on the disk with recesses and the flange of the hub, there are holes in which the legs of the corresponding friction washers are located.
