A view of the wheel bearing outer ring with a line of vision being a central axis of the wheel bearing outer ring at least one angle between a first one of the fastening elements and a second one of the fastening elements, which are neighbouring with respect to the circumferential direction of the wheel bearing outer ring, differs from an angle between a third one of the fastening elements and one of the fastening elements, which is neighbouring to the third one of the fastening elements with respect to the circumferential direction. All the angles are measured with respect to the central axis and in the circumferential direction. ## Claims ### Claim 1 A wheel bearing outer ring with a plurality of fastening elements that are configured to be fixed to the wheel bearing outer ring to a knuckle of a car and which are arranged at a radial outer side of the wheel bearing outer ring, wherein with respect to a view of the wheel bearing outer ring with a line of vision being a central axis of the wheel bearing outer ring at least one angle between a first one of the fastening elements and a second one of the fastening elements, which are neighbouring with respect to the circumferential direction of the wheel bearing outer ring, differs from an angle between a third one of the fastening elements and one of the fastening elements, which is neighbouring to the third one of the fastening elements with respect to the circumferential direction, and wherein all the angles are measured with respect to the central axis and in the circumferential direction. ### Claim 2 (depends on 1) The wheel bearing outer ring according to claim 1, wherein the number of the fastening elements is at most four. ### Claim 3 (depends on 1) The wheel bearing outer ring according to claim 1, wherein in the view central to the fixation points three of the fastening elements are within an angle of 90°, and wherein the angle is measured with respect to the central axis and in the circumferential direction. ### Claim 4 (depends on 1) The wheel bearing outer ring according to claim 1, wherein in the view one of the fastening elements is positioned a first angle away from a first neighbouring one of the fastening elements and is positioned a second angle away from a second neighbouring one of the fastening elements and the first angle differs at most by twenty percent of the first angle from the second angle. ### Claim 5 (depends on 1) The wheel bearing outer ring according to claim 1, wherein two of the fastening elements lie with respect to a radial direction of the wheel bearing outer ring approximately opposite to each other. ### Claim 6 (depends on 1) The wheel bearing outer ring according to claim 1, wherein the fastening elements extend in the view less than 40° in circumferential direction. ### Claim 7 (depends on 1) The wheel bearing outer ring according to claim 1, wherein all of the fastening elements are intersected by at least one imaginary plane that is perpendicular to the central axis. ### Claim 8 A structural unit comprising: a wheel bearing outer ring having with a plurality of fastening elements that are configured to be fixed to the wheel bearing outer ring to a knuckle of a car and which are arranged at a radial outer side of the wheel bearing outer ring, wherein with respect to a view of the wheel bearing outer ring with a line of vision being a central axis of the wheel bearing outer ring at least one angle between a first one of the fastening elements and a second one of the fastening elements, which are neighbouring with respect to the circumferential direction of the wheel bearing outer ring, differs from an angle between a third one of the fastening elements and one of the fastening elements, which is neighbouring to the third one of the fastening elements with respect to the circumferential direction, and wherein all the angles are measured with respect to the central axis and in the circumferential direction, and wherein the structural unit comprises a knuckle, to which the wheel bearing outer ring is fixed. ### Claim 9 A car comprising: a structural unit having a wheel bearing outer ring having with a plurality of fastening elements that are configured to be fixed to the wheel bearing outer ring to a knuckle of a car and which are arranged at a radial outer side of the wheel bearing outer ring, wherein with respect to a view of the wheel bearing outer ring with a line of vision being a central axis of the wheel bearing outer ring at least one angle between a first one of the fastening elements and a second one of the fastening elements, which are neighbouring with respect to the circumferential direction of the wheel bearing outer ring, differs from an angle between a third one of the fastening elements and one of the fastening elements, which is neighbouring to the third one of the fastening elements with respect to the circumferential direction, and wherein all the angles are measured with respect to the central axis and in the circumferential direction, and wherein the structural unit comprises a knuckle, to which the wheel bearing outer ring is fixed. ### Claim 10 (depends on 9) A motor vehicle according to claim 9, wherein a radial direction of extension of at least one of the fastening elements points vertically upwards in a condition in which the motor vehicle stands on a completely plain and horizontal underground.
