Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Examples of the principles of this disclosure are explained in greater detail with reference to the appended drawings.

(2) FIG. 1 shows a sleeve-like bearing receiving member according to an example; and

(3) FIG. 2 is a view of a sleeve-like bearing receiving member according to an example.

DETAILED DESCRIPTION OF THE DRAWINGS

(4) 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.

(5) 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.

(6) 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.

(7) 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.

(8) In an advantageous example, the plurality of apertures 103 may form a regular, hexagonal grid along the cylindrical sleeve wall 101.

(9) In an advantageous example, the apertures 103 may be formed in an irregular manner.

(10) 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.

(11) 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.

(12) 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.

(13) 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.

(14) 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.

(15) 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.

(16) 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.

(17) 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.

(18) 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.

(19) 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.

(20) The sleeve-like bearing receiving member may be part of a chassis component.
