Description

The radial bearing part has a radially inner sliding surface facing a sliding partner and a peripherally extending edge region, and wherein the axial bearing part substantially in a radial Level, that is orthogonal to the axial direction and has at least one substantially extending in the radial plane and inwardly projecting retaining tongue, which is brought into engagement with a respective holding recess in the edge region of the radial bearing part and held captive on the radial bearing part.

Built-up bundle shells are widely known. For example, deal EP 0 962 670 B1 . EP 0 962 671 B1 . EP 0 962 672 B2 . EP 2 233 759 B1 and DE 40 15 256 A1 with the attachment of the disc-shaped thrust bearing on the half-shell-shaped radial bearing part. In the cited documents, the attachment is carried out by deformation or caulking certain sections of the axial or radial bearing part.

It has been shown that unwanted stresses and deformations on the axial and / or radial bearing part are produced by the force acting on the axial or radial bearing part necessary for deformation or caulking. The present invention is therefore based on the object to further improve the attachment of the disc-shaped thrust bearing part to the effect that an economical and procedurally reliable and easy executable assembly is possible, which does not adversely affect the dimensional accuracy of the components.

This object is achieved in a built flange bearing shell of the type mentioned in the present invention that in the edge region outside the sliding surface extending in the circumferential direction groove-shaped recess is formed radially outwardly that the respective retaining recess extends in the radial direction up to the groove-shaped recess, ie opens there, that in the groove-shaped recess in the circumferential direction extending metallic wire-shaped part is inserted and that the retaining recess engaging in the holding recess is materially connected to the wire-shaped part, so that the thrust bearing Although at least in the axial direction slightly playful but in all directions, That is, in the axial direction, circumferential direction and radial direction, positively held captive on the radial bearing part.

Due to the inventive extension of the retaining recess into the groove-shaped recess, the retaining tongue engaging in the retaining recess can be brought into contact with the inserted wire-shaped part. As a result, in particular by welding, a cohesive connection of the retaining tongue to the wire-shaped part can be realized. The thrust bearing is thereby captive in all directions, that is, in the axial direction, circumferential direction and radial direction, held on the radial bearing part, without acting on the axial or radial bearing part deforming.

It proves to be advantageous in terms of mountability and to allow a slightly play-affixed mounting of the thrust bearing on the radial bearing part when the thickness of the wire-shaped part is greater than the depth of the groove-shaped recess.

In a further development of the invention, it proves to be advantageous if the depth of the groove-shaped recess is at least 30%, in particular at least 50%, and at most 100%, in particular at most 80%, of the thickness of the wire-shaped part.

In a further development of the invention, it proves to be advantageous if the radial bearing part has a plurality, preferably two or three, retaining recesses and the thrust bearing part correspondingly several, preferably two or three, retaining tongues. Of these two or three retaining recesses and their associated two or three retaining tongues of the thrust bearing part, two are then preferably arranged in the region of the lubrication grooves of the axial bearing part and the third in the vertex of the flange bearing shell.

In this way, with two or three retaining recesses and, correspondingly, two or three retaining tongues, it is possible to achieve a fixation of the axial bearing part on the radial bearing part uniformly distributed over the circumference of the half-shell-shaped flange bearing shell.

In a further advantageous embodiment of the invention it is provided that is attached to both sides of the respective end faces of the radial bearing part depending on a thrust bearing.

In a further development of the invention, it proves to be advantageous if all retaining recesses of the radial bearing part are formed open edge in the axial direction. In this way, the thrust bearing can be brought by a single translational axial joining operation on the radial bearing part in a mounting position. So there is no tilting with respect to the plane of the radial bearing part or an additional joining operation in the radial direction required.

Furthermore, it proves to be advantageous if the thrust bearing part has one or more substantially in the radial plane extending stop tongues, which cooperate with a respective stop recess in the radial bearing part such that a rotatability in the circumferential direction is limited. In this way, the thrust bearing is held in the mounting position limited rotatably on the radial bearing part.

The edge region of the radial bearing part is in an advantageous development of the invention over the sliding surface of the radial bearing part in the radial direction by machining, in particular by 0.35 mm to 1.5 mm, reset.

In terms of economy and to obtain a very accurate weld, it proves to be particularly advantageous if the cohesive connection is preferably made in an electron beam or laser beam welding process.

Furthermore, it proves to be advantageous if the wire-shaped part is a steel part and the thrust bearing part and / or the radial bearing part consists of a steel / aluminum or steel / copper composite material.
