Title
(DE) AXIAL-FEDERRING UND LAMELLENKUPPLUNG MIT EINEM SOLCHEN AXIAL-FEDERRING
(EN) AXIAL SPRING RING AND MULTI-PLATE CLUTCH HAVING SUCH AN AXIAL SPRING RING
(FR) RONDELLE-RESSORT AXIALE ET EMBRAYAGE À DISQUES MULTIPLES COMPRENANT UNE TELLE RONDELLE-RESSORT AXIALE
Abstract
(DE)
Die Erfindung betrifft einen Axial-Federring zur Separierung von Lamellen in einer Lamellenkupplung, mit umfangsverteilten Ringsegmentabschnitten (4) und Kröpfungen (5, 6), wobei die Ringsegmentabschnitte (4) eine Ebene (E) definieren, und die Kröpfungen (5, 6) von den Ringsegmentabschnitten (4) aus der Ebene (E) abgebogen und unter axialer Krafteinwirkung in Richtung der Ebene elastisch verformbar sind, wobei der Axial-Federring (2) aus einem zu einem Ring gebogenen und in einem Umfangsbereich einer Kröpfung (5, 6) gefügten Draht hergestellt ist. Die Erfindung betrifft weiter eine Lamellenkupplung (23) mit einem solchen Axial-Federring.
(EN)
The invention relates to an axial spring ring for separating plates in a multi-plate clutch, having circumferentially distributed ring segment portions (4) and offsets (5, 6), wherein the ring segment portions (4) define a plane (E), and the offsets (5, 6) of the ring segment portions (4) are bent out of the plane (E) and are elastically deformable in the direction of the plane under axial action of force, wherein the axial spring ring (2) is produced from a wire which is bent to form a ring and which is joined in a circumferential region of an offset (5, 6). The invention further relates to a multi-plate clutch (23) having such an axial spring ring.
(FR)
L'invention concerne une rondelle-ressort axiale destinée à séparer les disques dans un embrayage à disques multiples, comprenant des parties de segments annulaires (4) et des déports (5, 6) répartis sur la circonférence. Les parties de segments annulaires (4) définissent un plan (E) et les déports (5, 6) sont courbés hors du plan (E) à partir des parties de segments annulaires (4) et peuvent être déformés élastiquement sous l'action d'une force axiale en direction du plan. La rondelle-ressort axiale (2) est fabriquée à partir d'un fil métallique plié en un anneau et emboîté dans une zone périphérique d'un déport (5, 6). L'invention concerne également un embrayage à disques multiples (23) comprenant une telle rondelle-ressort axiale.
