DETAILED DESCRIPTION

[0068] FIG. 1 shows a schematic representation of a wheel control arm 100, according to a first example, in a top view. The wheel control arm 100 is employed in a wheel suspension of a vehicle, whereby the wheel suspension exhibits a wheel carrier for the support of a wheel of the vehicle. In this manner, the wheel control arm 100, according to this disclosure, allows for an effective absorption of forces, which have an effect on the wheel control arm 100 during the driving of the vehicle.

[0069] The wheel control arm 100 exhibits a first profile body 101, which exhibits a first narrow end 103-1, and a second narrow end 103-2 which extends opposite the first narrow end 103-1. Hereby, the first narrow end 103-1 is open and the second narrow end 103-2 is closed. The first profile body 101 moreover exhibits a first broadside 105-1 and a second broadside 105-2 that faces the first broadside 105-1. In the representation selected in FIG. 1, the second broadside 105-2 is not visible.

[0070] The first profile body 101 is curved along a longitudinal axis 107 of the profile body around the first narrow end 103-1. The first profile body 101 exhibits a first profile body end 109-1 and a second profile body end 109-2, whereby the broadsides 105-1, 105-2 of the first profile body 101 of the first profile body end 109-1 taper down towards the second profile body end 109-2.

[0071] The first profile body end 109-1 exhibits a first bearing seat 111-1 for fastening of the wheel control arm 100 to a vehicle component. The second profile body end 109-2 exhibits a second bearing seat 111-2 for fastening of the wheel control arms 100 to a wheel carrier.

[0072] The wheel control arm 100 furthermore exhibits a second profile body 113, which exhibits a third profile body end 115-1 and a fourth profile body end 115-2. Hereby, the third profile body end 115-1 exhibits a third bearing seat 117-1 that is not represented in FIG. 1 for fastening of the wheel control arm 100 to the vehicle component. The fourth profile body end 115-2 of the second profile body 113 is inserted in the open first narrow end 103-1 of the first profile body 101, and is, in particular, inserted between the first profile body end 109-1 and the second profile body end 109-2 in the open first narrow end 103-1 of the first profile body 101.
