Zugkraftbetätigter Kupplungsmechanismus mit Drehsicherung der Tellerfeder, insbesondere für ein Kraftfahrzeug.

摘要

Pulled-type diaphragm-spring clutch mechanism, comprising a cover (10) with a crown (13) and a skirt (12), at least one pressure plate (20), a diaphragm spring (30) and means (34, 40) to prevent the rotation of the diaphragm spring (30), comprising at least one radial protrusion (34) of the diaphragm spring (30). The mechanism according to the invention is characterised in that, for forming means of prevention of rotation of the diaphragm spring (30), the skirt (12) of the cover (10) has at least one local deformation (40) extending towards the outside of the cover and capable of interacting in a complementary manner and at least in a circumferential direction with the said radial protrusion of the cover. Application: motor vehicles.
