Friction couplings, especially for motorized vehicles, with a coupling carrier disc which can be secured to the crankshaft of an engine, an axially movable pressure plate, a leaf spring provided between the latter and the coupling carrier disc and which is supported, via radially outer zones, against the coupling carrier disc and which works on the pressure plate via zones which are radially located further inwards, in which, between this latter pressure plate and the coupling carrier disc, provision is made for elements for the transfer of the overturning (turning) moment, and with a pressure counterplate which, via spacer elements, may be held axially and firmly in rotation against the coupling carrier disc and with a coupling disc located between the aforesaid disc and the pressure counterplate. The aim of the present invention was to make these frictional couplings cheaper, to make them smaller or, also under given spatial conditions, to increase the diameter of the friction and thereby the work capacity, and, moreover, the object was to improve functioning and to lengthen effective duration. This is achieved in accordance with the present invention in that the spacer element is configured as a sheet moulding and in that said piece opens to the counterpressure plate on that side which is remote from the engine.
