Title (EN) CORRUGATED SPRING FOR A TORSIONAL VIBRATION DAMPER
(FR) RONDELLE ONDULÉE POUR AMORTISSEUR DE VIBRATIONS DE TORSION
(DE) WELLFEDER FÜR EINEN TORSIONSSCHWINGUNGSDÄMPFER
Abstract:
(EN) The invention relates to a corrugated spring (26), in particular for a torsional vibration damper (2) for a clutch disc (1), said corrugated spring (26) being essentially annular and has at least one first wave crest (32) and a second wave crest (34), the first wave crest (32) being arranged in a first corrugated spring region (28) having a first outer diameter (A1) and the second wave crest (34) being arranged in a second corrugated spring region (30) having a second outer diameter (A2) which is different from the first outer diameter (A1). The invention also relates to a torsional vibration damper (2) comprising said type of corrugated spring (26) and a clutch disc (1) comprising said type of torsional vibration damper (2).
(FR) L'invention concerne une rondelle ondulé (26), destinée en particulier à un amortisseur de vibrations de torsion (2) d'une plaque d'embrayage (1). La rondelle ondulée (26) a une forme sensiblement annulaire et comporte au moins un premier sommet (32) et un deuxième sommet (34). Le premier sommet (32) est disposé dans une première zone (28) de la rondelle ondulée qui a un premier diamètre extérieur (A1) et le deuxième sommet (34) est disposé dans une deuxième zone (30) de la rondelle ondulée qui a un deuxième diamètre extérieur (A2) différent du premier diamètre extérieur (A1). L'invention concerne également un amortisseur de vibrations de torsion (2) équipé d'une telle rondelle ondulée (26) et un disque d'embrayage (1) équipé d'un tel amortisseur de vibrations de torsion (2).
(DE) Offenbart wird eine Wellfeder (26), insbesondere für einen Torsionsschwingungsdämpfer (2) für eine Kupplungsscheibe (1), wobei die Wellfeder (26) im Wesentlichen ringförmig ausgebildet ist und mindestens einen ersten Wellenberg (32) und einen zweiten Wellenberg (34) aufweist, wobei der erste Wellenberg (32) in einem ersten Wellfederbereich (28) mit einem ersten Außendurchmesser (A1) und der zweite Wellenberg (34) in einem zweiten Wellfederbereich (30) mit einem zweiten, vom ersten Außendurchmesser (A1) verschiedenen, Außendurchmesser (A2) angeordnet ist, ein Torsionsschwingungsdämpfer (2) mit einer derartigen Wellfeder (26) und eine Kupplungsscheibe (1) mit einem derartigen Torsionsschwingungsdämpfer (2).
