Unit comprising a wheel bearing and at least one vehicle-sided fixed support

1. A unit, comprising:

a wheel bearing; and

at least one vehicle-sided fixed support, the wheel bearing being seated fixedly by way of at least one outer part in at least one bearing seat which is formed as an axial passage of a sheet metal formed part of the support, and at least one end section of the outer part being folded over radially in a plastic manner at least near the passage, in such a way that the end section engages axially behind the support,

wherein the passage has a linear inner contour forming a first side wall, a linear outer contour forming a second side wall, a first concavely curved contour extending from the inner contour, a second concavely curved contour extending from the outer contour, and a linear base interposed between the first concavely curved contour and the second concavely curved contour, and

wherein centrally located at the base is a radial narrow point, and axially, from the radial narrow point toward the inner contour and the outer contour, a radial internal cross-section of the passage uniformly decreases at decreasing axial distance intervals from the narrow point toward the inner contour and the outer contour.

2. The unit as claimed in claim 1 , wherein the axial spacing from the location, from which the internal cross-section begins to decrease in the direction of the narrow point, corresponds to at least half the maximum axial width of the passage which is oriented in the same direction as the bearing rotational axis.

3. The unit as claimed in claim 2 , wherein the outer contour, which is surrounded by the bearing seat, of an outer part of the wheel bearing which is seated in the bearing seat bears toward the inner contour of the passage, at least starting from a location and at the narrow point.

4. The unit as claimed in claim 3 , wherein the inner contour protrudes radially the furthest into the passage at least at the narrow point, in a circumferential manner about the bearing's rotational axis.

5. The unit as claimed in claim 3 wherein the outer contour which corresponds with the inner contour of the passage is deformed at least partially plastically toward the inner contour.

6. The unit as claimed in claim 1 , wherein the outer part is an outer ring of the wheel hearing having at least one raceway for rolling bodies, and in that at least the end section is configured on the outside to be rotationally symmetrical about the bearing's rotational axis of the wheel bearing.

7. The unit as claimed in claim 1 , wherein two of the passages are formed in the support.

8. The unit as claimed in claim 1 , wherein the support has at least two of the sheet metal formed parts, each of the sheet metal formed parts having one of the bearing seats.
