Abstract[German]
Die Erfindung betrifft einen Drehschwingungsdämpfer (10) zur Verringerung von Drehschwingungen in einem Antriebsstrang eines Fahrzeugs, aufweisend ein um eine Drehachse (12) drehbares Innenbauteil (14), mehrere umfangsseitig zueinander beabstandete Speichenfedern (16), ein mit dem Innenbauteil (14) über die Speichenfedern (16) mitdrehend verbundenes und entgegen einer Federkraft der Speichenfedern (16) gegenüber dem Innenbauteil (14) begrenzt verdrehbares Aussenbauteil (18), wenigstens ein reibwirksam zwischen dem Innenbauteil (14) und dem Aussenbauteil (18) angeordnetes Reibelement (42), wobei wenigstens eine der Speichenfedern (16) unter Bildung eines eine Verdrehbarkeit zwischen der Speichenfeder (16) und dem wenigstens einen Reibelement (42) zulassenden Freiwinkels (50) mit dem Reibelement (42) gekoppelt ist.[English]
The invention relates to a torsional vibration damper (10) for reducing torsional vibrations in a drive train of a vehicle, having an inner component (14) which can be rotated about an axis of rotation (12), a plurality of spoke springs (16) which are circumferentially spaced apart from one another, an outer component (18) which is connected via the spoke springs (16) to the inner component (14) so as to rotate therewith and which can be rotated to a limited extent with respect to the inner component (14) counter to a spring force of the spoke springs (16), at least one friction element (42) which is frictionally arranged between the inner component (14) and the outer component (18), wherein at least one of the spoke springs (16) is coupled to the friction element (42) so as to form a free angle (50) which allows rotatability between the spoke spring (16) and the at least one friction element (42).[French]
L'invention concerne un amortisseur de vibrations de torsion (10) permettant de réduire les vibrations de torsion dans une chaîne cinématique d'un véhicule, comportant un composant interne (14) qui peut tourner autour d'un axe de rotation (12), une pluralité de ressorts de torsion (16) qui sont espacés circonférentiellement les uns des autres, un composant externe (18) qui est relié par l'intermédiaire des ressorts de torsion (16) au composant interne (14) de manière à tourner avec celui-ci et qui peut tourner dans une mesure limitée vis-à-vis du composant interne (14) à l'encontre d'une force de rappel des ressorts de torsion (16), au moins un élément de frottement (42) qui est disposé en frottement entre le composant interne (14) et le composant externe (18), au moins l'un des ressorts de torsion (16) étant accouplé à l'élément de frottement (42) de manière à former un angle libre (50) qui autorise une rotation entre le ressort de torsion (16) et ledit élément de frottement (42).
