Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Examples of the principles of this disclosure are explained in greater detail with reference to the appended drawings.

[0023] FIG. 1 shows a sleeve-like bearing receiving member according to an example; and

[0024] FIG. 2 is a view of a sleeve-like bearing receiving member according to an example.

DETAILED DESCRIPTION OF THE DRAWINGS

[0025] FIG. 1 is a schematic illustration of a sleeve-like bearing receiving member 100 with a cylindrical sleeve wall 101 for receiving a plastics material sleeve 105 with a plurality of apertures 103. Furthermore, there is provided an aperture 109 which has a larger diameter than a diameter of the plurality of apertures 103.

[0026] In an advantageous example, the plurality of apertures 103 may be formed in a circular manner and/or be arranged with a fixed spacing along a diameter of the sleeve-like bearing receiving member 100.

[0027] The apertures 103 may be configured in several rows 113-1 to 113-5 and columns 115-1 to 115-4 along the cylindrical sleeve wall 101 so that a, for example, regular rectangular grid of apertures 103 is produced. The grid may, however, also be irregular.

[0028] The rows 113-1 to 113-5 of the apertures 103 may have a smaller spacing with respect to each other than with respect to the edges 119, 121 of the sleeve-like bearing receiving member 100.

[0029] In an advantageous example, the plurality of apertures 103 may form a regular, hexagonal grid along the cylindrical sleeve wall 101.

[0030] In an advantageous example, the apertures 103 may be formed in an irregular manner.

[0031] In an advantageous example, the plurality of apertures 103 may be subdivided into groups which in comparison with the spacing of the apertures 103 within a group, have a greater spacing between the groups.

[0032] In an advantageous example, one of the edges 119, 121 of the sleeve-like bearing receiving member 100 may be interrupted by a recess 117.

[0033] In an advantageous example, the plurality of apertures 103 are arranged in such a manner that there is no intersection between the apertures 103 and the edges 119, 121 of the sleeve-like bearing receiving member 100.

[0034] FIG. 2 is a schematic illustration of the bearing arrangement 200, formed by a sleeve-like bearing receiving member 100 with a cylindrical sleeve wall 101 which has a plurality of apertures 103, wherein there are configured at the apertures 103 collars 107 which engage in the plastics material sleeve 105 of the resilient bearing 201.

[0035] The plurality of apertures 103 is, for example, formed by means of a punching tool. This can be carried out in an operating step with the punching of the basic shape of the sheet metal bar piece.

[0036] Each aperture 103 is in this instance at least partially bordered by a collar 107 which protrudes into the inner side of the sleeve-like bearing receiving member 100. The plurality of collars 107 are marked by way of example by a selection. The positive-locking connection between the sleeve-like bearing receiving member 100 and plastics material sleeve 105 is preferably brought about by pressing the plastics material sleeve 105 into the sleeve-like bearing receiving member 100. This can be carried out using a pressing tool.

[0037] The collars 107 can after the pressing of the plastics material sleeve 105 engage in a positive-locking manner in the plastics material sleeve 105 and increase the retention between the plastics material sleeve 105 and sleeve-like receiving member 100.

[0038] In an advantageous example, the resilient bearing 201 may terminate in a positive-locking manner with the edge 119 and/or the edge 121 of the sleeve-like bearing receiving member 100.

[0039] In an advantageous example, there is a spacing between the termination of the resilient bearing 105 and the edges 119, 121 of the sleeve-like bearing receiving member 100.

[0040] The plastics material sleeve 105 often comprises plastics material for cost reasons. According to an advantageous example, the plastics material sleeve can be replaced by a metal sleeve.

[0041] The sleeve-like bearing receiving member may be part of a chassis component.
