## Abstract

A link for a link system for the attachment of a wheel carrier to a body of a vehicle, having a main body with a joint portion with a joint bearing receptacle for the articulated fastening to the body of the vehicle, a wheel carrier portion with a wheel carrier joint receptacle for the articulated fastening to a wheel carrier of the vehicle, and a connecting portion between the wheel carrier portion and the joint portion. In the joint portion, centers of area of the main body form a center of gravity line which is oriented centrally with respect to the longitudinal axis of the main body.

## Claims

### Claim 1

A link for a link system for the attachment of a wheel carrier to a body of a vehicle, said link comprising:
a main body including (i) a joint portion having a joint bearing receptacle for the articulated fastening to the body of the vehicle, (ii) a wheel carrier portion with a wheel carrier joint receptacle for the articulated fastening to the wheel carrier of the vehicle, and (iii) a connecting portion between the wheel carrier portion and the joint portion,
wherein, in the joint portion of the main body, a center of gravity line (S) of the main body is oriented centrally with respect to a longitudinal axis (LA) of the main body,
wherein a joint longitudinal axis passing through the wheel carrier joint receptacle is oriented non-parallel with respect to a joint longitudinal axis passing through the joint bearing receptacle,
wherein an acute angle extends between the joint longitudinal axis of the joint bearing receptacle and the longitudinal axis (LA) of the main body.

### Claim 2 (depends on 1)

The link as claimed in claim 1, wherein, in the joint portion, a depression is at least partially surrounded by lateral elevations.

### Claim 3 (depends on 1)

The link as claimed in claim 1, wherein the joint portion, the connecting portion and/or the wheel carrier portion are formed symmetrically or substantially symmetrically with respect to the longitudinal axis (LA) of the main body.

### Claim 4 (depends on 1)

The link as claimed in claim 1, wherein the joint portion is of bending-free or substantially bending-free form.

### Claim 5 (depends on 4)

The link as claimed in claim 4, wherein, in the joint portion, the center of gravity line (S) is arranged either on or substantially on a force action line (KL) between the joint portion and the wheel carrier portion.

### Claim 6 (depends on 1)

The link as claimed in claim 1, wherein, in the connecting portion, the center of gravity line (S) is vertically spaced from a force action line (KL) between the joint portion and the wheel carrier portion.

### Claim 7 (depends on 6)

The link as claimed in claim 6, wherein, in the wheel carrier portion, the center of gravity line (S) is arranged either on or substantially on the force action line (KL).

### Claim 8 (depends on 6)

The link as claimed in claim 6, wherein, at least in the connecting portion, the center of gravity line (S) is curved and spaced apart from the force action line (KL).

### Claim 9 (depends on 1)

A link system for the attachment of the wheel carrier to the body of the vehicle, the link system comprising at least one of the links of claim 1.

### Claim 10 (depends on 9)

The link system as claimed in claim 9, wherein the at least one link is formed as a transverse link.

### Claim 11 (depends on 1)

The link as claimed in claim 1, wherein the connecting portion is curved with respect to the longitudinal axis (LA) of the main body.

### Claim 12 (depends on 1)

The link as claimed in claim 1, further comprising depressions formed in opposing surfaces of the connecting portion.

### Claim 13 (depends on 1)

The link as claimed in claim 1, further comprising openings formed in the main body that are not oriented parallel to either of the joint longitudinal axes.

### Claim 14 (depends on 13)

The link as claimed in claim 13, wherein one of the openings has a larger diameter than the joint bearing receptacle.

### Claim 15 (depends on 13)

The link as claimed in claim 13, wherein, as viewed in a cross-section taken along an axis that is orthogonal to the longitudinal axis (LA) of the main body, a thickness of the connecting portion is reduced in a central portion as compared with side portions of the connecting portion.
