Description

The present invention relates to an axial roller bearing for a drive train of a motor vehicle, in particular for a torque transmission device, such as a transducer and / or damper. Furthermore, the invention relates to two Axialwälzlageranordnungen for a torque transmission device of a drive train of a motor vehicle. Furthermore, the invention relates to a torque transmission device for a drive train of a motor vehicle, in particular a converter and / or damper, preferably a torque converter and / or torsional vibration damper.

In the prior art, an axial rolling bearing of a torque converter of the torque converter constructed as a torsional vibration damper is supported on a circumferential side of a turbine hub of the torque converter and on a stator of a torque converter. By way of the turbine hub which can be configured in the axial direction on the turbine damper, an axial distance between the turbine hub and a damper hub can be bridged, taking into account an axial extent of the axial rolling bearing arranged therebetween. A trained as a Mitnehmerflansch input disk of the turbine damper is firmly connected by means of a Schweißnietverbindung with a turbine of the torque converter and thus also with the turbine hub. The use of a turbine hub is constructive and therefore relatively expensive to manufacture and consequently expensive and installation-intensive.

The DE 10 2009 030 442 A1 discloses for a drive train of a motor vehicle, a radial sliding bearing designed as a Mitnehmerflansch input disk of a torsional vibration damper for a turbine of a hydrodynamic torque converter on a damper hub of the torsional vibration damper. For this purpose, the input disk has a collar extending in the axial direction, on which radially on the outside sits an axial roller bearing which bridges a distance in the axial direction between the input disk and a stator or a stator component of the torque converter. A turbine wheel of the torque converter is thereby fixed by means of a welded rivet connection to the input disk, which is axially supported on a circlip on the one hand and axially via a counterplate of the weld rivet connection on an extension of the damper hub or an extension of an output disk of the torsional vibration damper designed as a force transmission flange.

Here, for example, in the application of the invention to a turbine damper of a hydrodynamic torque converter, can be dispensed with a turbine hub. Furthermore, a distance in the axial direction between an input disk of the turbine damper and a stator or a Leitradbauteil the torque converter should be realized in terms of design and manufacturing technology simple and inexpensive, taking into account a small radial space.
