Description

The invention relates to a centering device for a release bearing of a release device.

Conventional release bearing centering devices typically have a self-centering function.

For this purpose, according to the known state of the art, an additional flanging ring with a disc spring must be mounted on one of the two bearing rings (outer or inner ring) of a release bearing.

Currently, this is done by a crimping in the assembly. The crimp ring serves to define the mounting position of the disc spring and the radial displacement and to attach the bearing to the associated Umbauil (for example, a piston of a release system).

By the bias of the diaphragm spring an axial force is effected. In conjunction with the coefficient of friction of the contact partners, a defined radial displacement force arises from the axial force of the disc spring.

Due to the design, the flanging operation of the flanging ring takes place without an anvil. As a result, the folding of the intended area on the flare ring takes place undefined, whereby an exact deformation of the defined area on the flare ring by 90 ° is difficult.

This leads to fluctuations with respect to the installation position of the plate spring and thus to fluctuations in the radial displacement force.

It is therefore an object of the present invention to provide a centering device for a release bearing of a release device, which is inexpensive and material-saving to produce and ensures improved, defined installation with a low tolerance.

This object is achieved by the features of the independent claim. Further advantageous developments are the subject of the dependent claims.
