Title
(DE) TORSIONSDÄMPFVORRICHTUNG
(EN) TORSION DAMPING DEVICE
(FR) DISPOSITIF D'AMORTISSEMENT DE TORSION
Abstract
(DE)
Die Erfindung betrifft eine Torsionsdämpfvorrichtung (1), insbesondere für eine Kraftfahrzeugkupplung, die zur Halterung einer Anzahl Federelemente (2) einen Käfig (3) aufweist, der zwei im axialen Abstand (a) zueinander angeordnete Deckscheiben (4, 5) umfasst, wobei die beiden Deckscheiben (4, 5) mittels U-förmig ausgebildeter Abstandsstücke (6) verbunden sind und auf Abstand (a) gehalten werden und wobei die U-förmigen Abstandsstücke (6) jeweils zwei Schenkel (7, 8) sowie einen zwischen diesen liegenden Verbindungsabschnitt (9) aufweisen. Um den Bauraum zwischen den Deckscheiben möglichst wenig zu beschränken, sieht die Erfindung vor, dass der eine Schenkel (7) des Abstandsstücks (6) an der von der einen Deckscheibe (4) abgewandten Stirnseite (10) der anderen Deckscheibe (5) aufliegt.
(EN)
The invention relates to a torsion damping device (1), particularly for a motor vehicle clutch, having a cage (3) for holding a number of spring elements (2). The cage comprises two cover plates (4, 5) disposed at an axial distance (a) to each other, wherein the two cover plates (4, 5) are connected by means of spacers (6) that are configured in a U-shape, and are kept at a distance (a), and wherein the U-shaped spacers (6) each have two legs (7, 8) and a connecting section (9) located between them. In order to limit the available space between the cover plates as little as possible, the invention provides that one leg (7) of the spacer (6) comes to rest on the face (10) of the one cover plate (5) facing away from the other cover plate (4).
(FR)
L'invention concerne un dispositif d'amortissement de torsion (1), en particulier pour un dispositif d'accouplement de véhicule automobile, qui présente, pour le support d'un certain nombre d'éléments de ressort (2), une cage (3) comprenant deux disques de recouvrement (4, 5) disposés à une certaine distance axiale (a) l'un de l'autre, les deux disques de recouvrement (4, 5) étant reliés au moyen d'entretoises (6) réalisées en forme de U et étant maintenus à la distance (a), et les entretoises (6) en forme de U présentant respectivement deux branches (7, 8) ainsi qu'une section de liaison (9) située entre ces dernières. Afin de limiter le moins possible l'encombrement entre les disques de recouvrement, l'invention prévoit qu'une première branche (7) de l'entretoise (6) s'appuie contre une face frontale (10), opposée à un premier disque de recouvrement (4), de l'autre disque de recouvrement (5).
