[0031] The disclosure will be explained further below with reference to an exemplary embodiment.

[0032] FIG. 1 shows a three-dimensional view of an exemplary wheel suspension obliquely from the front.

[0033] FIG. 2 shows a view of the wheel suspension from FIG. 1 from below.

[0034] FIG. 3 shows a three-dimensional top view of the wheel suspension.

DETAILED DESCRIPTION OF THE DRAWINGS

[0035] The wheel suspension according to FIG. 1 comprises a first wheel guiding element 1, which is designed in the form of what is known as a transverse link. The first wheel guiding element is oriented at least approximately in the vehicle transverse direction Q. The wheel suspension also comprises further wheel guiding elements 2, which in this specific case, are likewise designed as transverse links, and are oriented at least approximately in the vehicle transverse direction Q. All wheel guiding elements 1, 2 connect a vehicle body, which is formed by an axle support 3 in this case, to a wheel carrier 4 of the vehicle here. The wheel guiding elements 1, 2 are connected to the axle support 3 or to the wheel carrier 4 via bearings or joints here.

[0036] As shown in FIG. 1, and in particular, in FIG. 3, the wheel suspension also comprises what is known as a damper strut 5 and a helical spring 6 arranged separately from this damper strut 5.

[0037] The damper strut 5 and the helical spring 6 serve to damp or cushion vibrations of the wheel with respect to the chassis of the vehicle. Therefore, they are both, that is to say, both the helical spring 6 and the damper strut 5, at their upper end when viewed in the vehicle vertical direction H, supported on a vehicle chassis or vehicle body, not depicted. Both the damper strut 5 and the helical spring 6 are arranged oriented at least approximately in the vehicle vertical direction H.

[0038] Here, the damper strut 5 is mounted, by way of its lower end, on the wheel carrier 4. The connection of the damper strut 5 to the wheel carrier 4 is clearly shown, in particular, in FIG. 2, in the view of the wheel suspension from below.

[0039] Here, the damper strut 5 is arranged in a manner projecting through a passage opening 1.1 in the first wheel guiding element 1. For this purpose, the first wheel guiding element 1 comprises a passage opening 1.1 which is arranged in the first wheel guiding element 1 in a concavely formed position. The passage or insertion of the damper strut 5 through the first wheel guiding element 1 allows the damper strut 5 to be connected to the wheel carrier 4 in a very deep position, when viewed in the vehicle vertical direction. This deep connection to the wheel carrier 4 allows sufficiently high damper transmission ratio, and at the same time, a greater damper strut length.

[0040] As shown in FIG. 3, in particular, the helical spring 6, in contrast to the damper strut 5, is not connected to or supported on the wheel carrier 4, but rather one of the wheel guiding elements 2 (here referred to as spring links).

[0041] Both the spring link 2, on which the helical spring is supported, or on which the helical spring rests, and the first wheel guiding element 1, through which the damper strut 5 projects, are arranged in a lower link plane. This lower link plane is spanned by the first wheel guiding element 1, the spring link 2, and a further of the wheel guiding elements 2 (which is designed as what is known as a toe link in this case), the first wheel guiding element 1 and the spring link 2 being provided below the wheel rotation axis R, when viewed in a vehicle vertical axis H.

[0042] The first wheel guiding element 1 is arranged in front of the wheel center axis M, or the wheel rotation axis in the vehicle direction of travel L (which is also the vehicle longitudinal direction L in this case), when viewed during forward travel of the vehicle here, while the spring link 2 is arranged behind the wheel center axis M.

[0043] In this exemplary embodiment, two of the further wheel guiding elements 2 are located in an upper link plane (that is to say, above the wheel center axis M, when viewed in he vehicle vertical direction H).
