FIG. 2 shows a schematic sectional illustration for illustrating the construction of a pendulum support with the device according to the invention according to FIG. 1.
Gemäß Figur 1 weist eine erfindungsgemäße Vorrichtung 1 zur Drehmomententkopplung und Übertragung einer axialen Kraft von einem ersten - hier nicht dargestellten - Bauteil auf ein zweites - hier nicht dargestelltes - Bauteil eine erste Buchse 2 und eine zweite Buchse 3 auf. Die erste Buchse 2 ist über ein stoffschlüssig daran ausgebil- detes Verbindungselement 10 mit dem ersten Bauteil verbunden. Ferner ist die zweite Buchse 3 unmittelbar mit dem zweiten Bauteil verbunden. According to FIG. 1, a device 1 according to the invention for torque decoupling and transmission of an axial force from a first component (not shown here) to a second component (not shown here) has a first socket 2 and a second socket 3. The first socket 2 is connected to the first component via a connecting element 10 formed integrally thereon. Furthermore, the second bushing 3 is directly connected to the second component.
Räumlich zwischen den beiden Buchsen 2, 3 sind zwei als Nadellager ausgebildete Axiallagerelemente 4, 5 zur drehbaren Lagerung der beiden Buchsen 2, 3 zueinander angeordnet. Das jeweilige Nadellager umfasst einen Axialnadelkranz mit einem aus einem Axialkäfig 13, 14 mit integrierten Nadelrollen 1 1 , 12. Die erste Buchse 2 bildet eine Einhausung für die beiden Axiallagerelemente 4, 5, sodass die beiden Axiallagerelemente 4, 5 radial und axial innerhalb der ersten Buchse 2 angeordnet sind. Die zweite Buchse 3 weist eine radiale Ausprägung 6 auf, an der die Nadelrollen 1 1 , 12 der beiden Axiallagerelemente 4, 5 axial zur Anlage kommen. Mithin bildet die radiale Ausprägung 6 eine jeweilige Laufbahn für die Nadelrollen 1 1 , 12 des jeweiligen Axiallagerelements 4, 5 aus. Ferner ist eine jeweilige Axialscheibe 7, 8 axial zwischen der ersten Buchse 2 und dem jeweiligen Axiallagerelement 4, 5 angeordnet.

Zum axialen Vorspannen der beiden Axiallagerelemente 4, 5 ist axial zwischen der ersten Buchse 2 und der am ersten Axiallagerelement 4 angeordneten Axialscheibe 7 ein Federelement 9 angeordnet, das als Tellerfeder ausgebildet ist. Dabei ist die Kraft des Federelements 9 kleiner als eine Kraft, die ein umlaufend umgebördelter Schenkel der ersten Buchse 2 aufnehmen kann. Spatially between the two bushes 2, 3 are designed as a needle bearing thrust bearing elements 4, 5 for rotatably supporting the two sockets 2, 3 to each other.

For axial prestressing of the two axial bearing elements 4, 5, a spring element 9 is arranged axially between the first bushing 2 and the axial disk 7 arranged on the first axial bearing element 4, which spring element is designed as a disk spring. The force of the spring element 9 is smaller than a force that can receive a circumferentially flanged leg of the first sleeve 2.
Die erste Buchse 2 ist über das erste Bauteil mit einem Drehmoment und einer axialen Kraft beaufschlagbar, wobei die zweite Buchse 3 aufgrund der beiden im Kraftfluss zwischen der ersten und der zweiten Buchse 2, 3 angeordneten Axiallagerelemente 4, 5 die axiale Kraft im Wesentlichen drehmomentfrei aufnimmt.
